Planet generator

The Imperium contains millions of settled planets. Such is the number of these planets that an almost limitless variety of environments can be created for the setting of your game. Below is detailed a method for generating planetary information, and a standardized layout for presenting the information. The steps below allow the generation of a planet within the Imperium that holds some form of settlement and society.

Obviously, there are many more planets in the galaxy that are devoid of life than there are which bear civilisation: in any star system, usually only one, sometimes two, rarely three, and virtually never more than four of the planets will be settled. Most of the planets in a system are simply too inhospitable, even for the most inventive of colonists and most lengthy of terraforming projects. The steps detailed below for generating a planet will create a planet that is within the parameters where civilisation can be easily established, or made possible by the stubbornness of humanity and the technology of the Adeptus Mechanicus.

Some of the steps have tables which allow you to randomly generate traits for the planet, all of which use a d100, and some of which will then require the rolling of one or more d10 to get a further definition. Other steps have no random tables, and are merely a suggestion of what kind of details you should create for the planet to make it complete and distinctive.

When generating a planet you can use as many of the random tables as you wish, or you can simply select one of the options from each table. While it can be entertaining to randomly generate as many of the planet’s features as possible, a planet is sometimes being created because it is required for a particular scene or scenario in a game of Dark Heresy, so the randomly generated traits may not be suitable or desirable: the GM should ignore or reroll any features that do not suit the requirements or tone of the game being played, or simply select the most suitable.

The details generated by this system provide only the basics of a planet’s size, geography and social basics. The details, colour and flavour must be added by the Dark Heresy GM (or other 40k RPG) and players as required by their campaign.

Check out the System generator for fluffing the system the planet in question is present in.

Class:

The class of a world describes what type of planet it is, what kind of civilisation and society can be found on the planet, what level of technology is commonly used on the world, and what kind of relationship the people of the planet have with the Imperium.

Planet Class (d100)
01-15	Hive World: The most heavily-developed worlds in the Imperium, covered in hive arcologies, with populations often peaking at the tens of billions. Life is generally good on the surface, but generally sucks eggs on the underside. Keep in mind that this generator was made with the relatively densely-populated Calixis sector in mind. For other sectors, these worlds will be a much rarer sight. If rolling multiple worlds, this world type needs at least one nearby Agri-world to feed its citizens.
16-19	Penal World: Class of Imperial world that functions as a military prison planet. A single such world's population consists entirely of criminals drawn from hundreds of different worlds.
20-27	Agri-World: Lightly-urbanized worlds which have been completely converted for use in food production, be it natural or hydroponic; grain, vegetables, meat and hide, or the occasional alien fungus or long pork casserole. Sometimes ruled directly by the Administratum.
28-32	Forge World: Overworked factory planets owned by the Adeptus Mechanicus to pump out all sorts of goodies for the Astra Militarum: Guns, Titans, Ships, Power armor, or simple consumer goods are all manufactured in continent-spanning manufactorums. The Adeptus Mechanicus Forge World Creation Tables aren't a bad supplement for this result. If rolling multiple worlds, this world type needs at least one nearby mining world to supply it with raw materials.
33-38	Mining World: Metal and mineral-rich planets, covered in city-sized mines and refineries, producing a fuckton of raw materials for the local Forge world. Often the retirement home and final resting place for criminals and 'criminals' alike.
39-44	Developing/Civilised World: 'Adolescent' colony Worlds that just sort of sat there and were allowed to develop on their own before the IoM came around asking for tithes. Often highly balkanized and highly culturally diverse, yet decently developed with a population somewhere in the million-billion bracket.
45-49	Fortress World: Well-guarded and armed to the teeth, these worlds are the haunts of the best of the Astra Militarum, and may even be graced by a passing Space Marine chapter. Military service is often on these worlds what agriculture is on a primitive world: Everybody does it, has done it for generations, and will do it until everybody dies.
50-53	Feudal World: Sword-and-Psykery worlds whose development peaked in the late medieval/early renaissance age, but stalled at gunpowder, castles, thatched roofing, and courtly intrigues. These worlds generally keep to themselves, unless something has gone seriously wrong.
54-58	Feral World: Wild, backwater worlds that only technically qualify as a colony, with nomadic hunter-gatherers fighting tooth-and-nail to live another day. May be a failed colony, or a plain Death World. Many inhabitants don't even know there is an Imperium.
59-64	Shrine World: So you go to church every Sunday? How about living there? How about having your whole planet being one mega-Vatican, covered in shiny gothic cathedrals and temples, and living and breathing its own brand of the Imperial Cult? Naturally, these worlds are often dominated by the Ecclesiarchy, and many a true believer from around the galaxy makes pilgrimage here.
65-68	Cemetery World: Consecrated worlds that serve as the final resting place of the Martyrs and heroes of the Imperium. They may range from the mausoleums of a noble house or a brave Space Marine company, or the unmarked and paved-over field from a nearby hive world.
69-73	Pleasure/Paradise/Garden World: Walled gardens where the rich and powerful can unwind and sow their oats, with the populace living to wait on them hand and foot, or step aside and make art, music, and pretty things. Often a beautiful place to live, as long as nobody takes it too far.
74-76	Death World: If it's not the molecular acid rain, it's the Rape-spiders. These worlds are near impossible to live on. Anyone who can live here more than ten years would make a perfect Space Marine.
77-80	Frontier World: A newly discovered, newly settled, poorly-explored world that's a bit rough around the edges. Usually, inhabitants must fend for themselves while their sponsor world focuses on other matters.
81-83	Quarantined World: Something bad has happened here, but not quite bad enough for Old Reliable. Instead, all access to this world has been cut off while the upstart WAAAGH!, crotchrot epidemic, or warp outbreak runs its course, one way or the other. Whatever happened, roll 1d80 on this table to establish this world's original class, before everything went to shit in a stain.
84-89	War World: You know the mantra. In the grim darkness, there is only war. There's only been war here for generations. It's likely nobody remembers what all the fighting is about, and the thing they've been fighting over was long since destroyed, and that that thing is the planet itself. But it wasn't always this way. Roll 1d80 on this table to see what this world was originally like before one thing led to another.
90-92	Dead World: Be it naturally barren, Tyranids, Exterminatus, natural disaster, unsustainable living, the end result is the same: No atmosphere, no civilization, not a cell of life to be found. The vast majority of planets are lifeless, but this particular world was once inhabited. Roll 1d80 on this table to estalish this world's original class.
93-94	Forbidden World: As on a Quarantine world, for one reason or another, Imperial Authority has barred access to this world. Usually a very good reason. So good they won't tell you what it is. They have a good reason for that, too. They can tell you it, but only if you ask, and anyone asking that many questions is either an Inquisitor or a heretic.
95-98	Xenos World: This world is the homeworld or colony of a primitive xenos race, and lies outside the control of the Imperium of Man. Usually tolerated as long as they pose no threat to the Imperium, and aren't sitting on anything too valuable.
99-100	Gas Giant: A giant planet made mostly of hydrogen and helium gas, with no solid ground to speak of. If anyone lives here, they live in the drifting cloud cities. More likely, though, it's the myriad of moons these planets tend to have, that have been settled. If you really like this table, you'll really like this type of planet. If the planet size is rolled very high, you can rule it to be a Brown Dwarf rather than a Super Jupiter. Check out the System generator table for a better way to determine whether its a regular Gas Giant, a Gas Titan or a Brown Dwarf.

Tech Level:

The level of technology common on a planet will determine a lot about its society and economy, and will limit what is available to be bought and traded there. The tech level given for a world is not an absolute limit on what can be found there; it is simply a measure of what technological level the indigenous people possess, and is what is most common on the world. An ‘Industrial’ world can still have a spaceport in orbit and a ‘High Imperial’ settlement as its capital; the mass of the locals are simply kept at the lower level so that they may be more easily controlled and administered.

The tech level of a planet is determined by generating a value based on the class of the world. Find the class on the first table below, and use the listed value to determine the planet’s tech level, as defined on the second table.

Tech Value
Hive	36+2d10
Penal	15+3d10
Agri	15+3d10
Forge	50+1d10
Mining	15+4d10
Developing	20+2d10
Fortress	40+2d10
Feudal	5+1d10
Feral	1d10

Quarantined/Dead	Use prev. class
War	Prev. class or 20+2d10
Death	4d10
Frontier	15+2d10
Forbidden	6d10
Xenos	6d10
Gas Giant	30±4d10

\*Quarantined worlds and Dead worlds are worlds that previously had another class before being subjected to whatever event gave them their current class. Use the value for the planet’s original class. War Worlds are the same, except that a backward world can't sustain total war conditions without a tech upgrade; use prev class for what tech it had before the outbreak of the war, *but* if it was formerly Feral or Feudal, roll 20+2d10 for the tech the war is being fought with.

Tech Level
01-05	Stone Age: Inhabited by people who live in small family groups, dwell in caves or rough shelters and use only the most basic of tools made of stone. People survive by hunting and gathering.
06-10	Iron Age: The people have started to learn how to shape and work iron to make more effective tools and weapons. They are also living in more substantial and sturdy buildings. Hunting and gathering is still common, though small farms may be seen dotted about.
11-15	Steel Age: The use of iron has evolved into the manufacture of alloys to make steel for weapons, armour and tools. Farming and trade are ways of life for most people, and civilisation has started to gather in fortified villages and towns. The ruling classes live in large stone castles. Communication networks of couriers and carrier birds are common.
16-20	Pre-Industrial: The underclass lives mostly by farming, and there is a richer class starting to make use of new technologies and mechanical devices to aid in manufacturing. Printing presses make education and distribution of information more efficient.
21-25	Industrial: Has completely moved on from small farms and independent manufactories. Everything is mechanised and automated. The population mostly lives in large cities, and computers are starting to become common in all things. Solid projectile weapons are the norm for military forces, and advanced armour has started to appear for personnel and vehicles.
26-30	Early Space: Has developed basic space flight, and may have established settlements on its own moons, and even close neighbouring planets in the same system. Basic las weapons may have been developed.
31-35	Advanced Space: Has explored their own system, and colonised any viable planets to be found there. Las weapons are common, and cybernetics are starting to become practical.
36-40	Warp Space: Has seen the development of warp drives and Geller fields, and the inhabitants are capable of traveling the galaxy beyond their own system. Powerful computers are common. Cybernetics and advanced medical techniques have been developed that border on Imperial level augmentation and rejuvenants. Primitive models of more advanced weapons, like plasma and needle weapons, are rare but present.
41-45	Low Imperial: The advanced technologies of the Imperium start to be seen, but are not always available. Standard issue and common weapons and armour can be easily found, but rare, expensive or very high tech items are still unavailable most of the time (no items with rare or very rare availability can be found on these worlds).
46-50	Mid Imperial: Most of the technology of the Imperium can be found. Only the most obscure or scarcely found items of technology can’t be found on these worlds (very rare availability items cannot be purchased). Most Imperial worlds are at this level.
51-55	High Imperial: The peak of Imperium technological advancement outside of the greatest hive worlds and Adeptus Mechanicus worlds. Anything and everything that can be bought on the open market can be found on these worlds, and the local troops have access to the most advanced weapons, armour and equipment.
56-60	Advanced: Have access to limited or developing technology. In the Imperium of Man only the greatest hive worlds and forge worlds have this level of technology. Although it wouldn't be surprising if some Inquisitors, who at least can be trusted to not fuck up all the time by both their fellows and the Mechanicus, have a planet or two that run an actual research facility that legitimately researches new technology.

Size of Star:

The size of the star that a planet orbits can have a significant effect on the economy and military importance of the planet, as the gravity well projected by the star determines the size of the system’s warp zone.

Size (d100)
01-05	Tiny
06-15	Small
16-75	Medium
76-85	Large
86-95	Huge
96-100	Giant

Galactic Position:

The coordinates which describe the planet’s location in the galaxy. The coordinates are given as 5 pieces of information, and is written with each separated by a slash, like this: AB/CDE/FG/123/456.

The first two letters are used to indicate what Segmentum the planet is in. The codes used are: SO for Solar, OB for Obscurus, PA for Pacificus, TE for Tempestus and UL for Ultima.

The next piece of information is a three letter code that indicates the sector of space that the planet is in. In the case of Calixis, CAL is used. Every sector of the Imperium has its own three digit code that is used in the coordinates of planets in that sector.

Third is a two letter code that indicates what sub-sector of the indicated sector the planet is in. Calixis’ sub-sectors use the following codes: PE for The Periphery, MM for the Markayn Marches, MA for Malfian, GR for Golgenna Reach, JR for Josian Reach, DM for Drusus Marches, AD for Adrantis and HA for Hazeroth.

On the last page of this article is a chart of the Calixis Sector. This chart is divided into squares, each of which is 2 light years across. The squares are numbered across the bottom (Trailing) edge and up the left (Rimward) edge. These numbers are used as grid reference coordinates to indicate a planet’s location within the sector.

The first three-digit number is used to indicate the planet’s grid reference along the Trailing edge. The second three-digit number is used to indicate the planet’s grid reference up the Rimward edge. The first two digits in each case indicates what square the planet is in, and the third digit is a measure of how many tenths of a square the planet lies into the square. Using this system it is easy to give the location of any planet in the Imperium.

Obviously this system is not precise enough for stellar navigation, but it adequately fills the role of allowing us to plot a planet’s location for purposes of game-play.

Sector:

The galaxy of the Imperium is divided into administrative sectors, each of which has its own sector governor and administratum infrastructure. While each sector’s administration and authority is obviously still beholden to the powers of Holy Terra, they are mostly self functioning and largely autonomous. A sector usually also has a Conclave of the Inquisition assigned to watch over it, led by a Lord Inquisitor.

Sub-sector: All sectors are divided into sub-sectors, and this is which sub-sector the planet can be found in.

Planetary Governer: One person on each planet is held responsible for the payment of the required tithe when the Imperium shows up to collect. The manner in which the planet is governed and the methods used to gather the tithe are beyond the concern of the Imperium. All the powers of Terra care to know of planetary politics is who the responsible individual is. The title used on the planet varies from place to place; ‘Governor’ is simply a generic title used for bureaucratic ease.

Adepta Presence:

The branches of the Adeptus Terra are present on different worlds in varying degrees. To determine what Adepta are present on a planet, and to what extent they are involved in the planet’s politics and daily life, consult the tables below. At each class of world each branch of the Adeptus Terra is listed with a dice value. Roll the indicated dice for each Adepta and consult the ADEPTA PRESENCE table below to determine the normal everyday presence and influence that Adepta has on the world.

Following the tables there is a brief explanation of what each level of presence means. For purposes of simplicity, the Inquisition and Adeptus Ministorum are included here as well, even though they are not strictly branches of the Adeptus Terra. The system is very broken however, and you’re best of just using your own method to determine these numbers

For each Adeptus, the result you obtained corresponds to a line on this table, indicating how important is the presence of this adeptus :

Roll Adepta Presence
01-03	None. No purpose at all best used for Xenos Worlds
04-06	Token. For administrative purposes only.
07-09	Slight. Specific duties; not involved in wider planetary affairs.
10-12	Small. Involved, but quietly and unobtrusively.
13-15	Moderate. Has offices and planetary duties, and are widely known.
16-18	Notable. A powerful force in its own area of the planet.
19-21	Significant. Controls its area, and has a say in wider planetary matters.
22-24	Major. A powerful and influential force throughout the planet.
25+	Dominating: One of, if not the, most powerful and influential forces on the planet.

Size:

The size of a world is defined by its equatorial circumference. The smallest planets may have a circumference of only 5,000 kilometres, and the truly massive planets may reach 500,000 kilometres. (To provide a sense of scale, Holy Terra herself has a circumference of 40,000 kilometres).

91-95	Enormous: (10d10)x4
96-100	Massive: (10d10)x5
Gas Giant Modifier: +55

Axial Tilt:

The degree by which a planet leans to the side on its axis determines how severe its seasonal variations are. A planet with no axial tilt experiences no change of seasons, with a greater tilt causing greater variation in seasonal conditions. Thus, it gets hotter in the summer, and colder in the winter. The northern hemisphere will experience summer while the southern has its winter, and vice versa.

For the table below, the planet's temperature is modified for its summer and winter, but stays as given for its autumn and spring. The rolled modifier is applied to both the maximum and minimum temperatures given, so, for instance, ±10°C to a 30°C world, with a 50°C equator would result in a seasonal range of 20°C to 40°C, with 40°C to 60°C equatorial temperatures.

The seasonal modifier may move the temperature into another bracket on the temperature table. When this happens, the affects of the new bracket take effect.

Tilt
d100	Axial Tilt	Seasonal Variation
01-05	None	None
06-15	Slight (1-5°)	± 5°C/41°F
16-30	Notable (6-15°)	± 10°C/50°F
31-70	Moderate (16-25°)	± 20°C/68°F
71-85	Large (26-35°)	± 40°C/104°F
86-95	Severe (36-45°)	± 60°C/140°F
96-100	Extreme (46°+)	± 80°C/176°F

Length of Day:

The length of a planet’s day, the time taken for it to complete a single revolution around its polar axis, is given as a number of standard hours. The roll to randomly determine the length of a planet’s day gets a modifier based on the size of the planet:

Length of Year:

The length of a planet’s year is given as the number of Terran days it takes to complete one full rotation of its local star. Divide the rolled number by 365 to see how many Terran years this is. To determine how many local days make up a local year, simply multiply the number of days in the year by 24, then divide that number by the length of the planet’s day.

Gravity:

Most planets that have civilisation on them have a gravity that is equal to Terran gravity, or close enough that humanity can easily adapt to life there.

Roll Gravity Level
01-05	Very Light (0.1 to 0.5 G): Don't trip and fly into orbit! +4 Agility bonus for movement, +8 to Strength and Toughness levels for Encumbrance, +4 Strength for Throwing. Jumping and leaping distances get quadrupled, fall damage gets quartered.
06-15	Light (0.5 to 0.7 G): Lightfooted. +2 Agility bonus for movement, +4 to Strength and Toughness levels for Encumbrance, +2 Strength for Throwing. Jumping and leaping distances get doubled, fall damage gets halved.
16-90	Standard (0.8 to 1.2 G): Normal or easily adaptable. No modifiers.
91-95	Heavy (1.3 to 1.5 G): A bit of a workout. -2 Agility bonus for movement, -4 to Strength and Toughness levels for Encumbrance, -2 Strength for Throwing. Jumping and leaping distances get halved, fall damage gets doubled.
96-100	Very Heavy (1.5 to 2 G): Don't trip and shatter your bones! -4 Agility bonus for movement, -8 to Strength and Toughness levels for Encumbrance, -4 Strength for Throwing. Jumping and leaping distances get quartered, fall damage gets quadrupled.

Atmosphere:

The gasses that make up a planet’s atmosphere are numerous, and occur in varying degrees and proportions. A detailed description of a planet’s atmospheric makeup is not necessary for gaming purposes; we need only be concerned with whether or not humans can breathe easily, and how dangerous the air is if it is not within the range that is conducive to human respiration.

Gas Giant Modifier +60 Roll Atmosphere

Atmosphere
01-70	Normal: Safe to breathe
71-85	Bearable: A Bearable atmosphere can be breathed normally for a short time, but carries a slight abnormality, will create an unfavourable taste in the mouth, and will prove fatal if breathed for too long. Any character subject to such an environment without a respirator or rebreather can breath normally for a number of hours equal to their Toughness bonus, and must then return to a normal atmosphere (natural or artificial). Being subject to a bearable atmosphere for any longer will give the character one fatigue level per hour. Once the character falls unconscious due to fatigue they will die one hour later if not provided with proper air to breathe.
86-92	Tainted: A Tainted atmosphere is even more dangerous. A character can only breathe a tainted atmosphere for a number of minutes equal to their Toughness bonus, and then gain a fatigue level per minute longer. Once unconscious due to fatigue, the character will die one minute later if still in the tainted atmosphere.
93-97	Poisonous: A Poisonous atmosphere is made up of gasses that are quickly lethal to humans. A character can only survive unhampered in such conditions for a number of rounds equal to their Toughness bonus, and then gain a level of fatigue each round until unconscious. They will die after one more round in the poisonous atmosphere.
98-100	Deadly: In a deadly atmosphere, a character will survive for a number of rounds equal to their Toughness modifier, gaining a fatigue level each round, and will then die instantly. At the GMs discretion, the natives of a planet, through evolutionary change, may be able to endure a bearable, tainted or poisonous atmosphere without penalty.

Hydrosphere:

The hydrosphere of a planet is how much water the surface and the atmosphere contains. This can be water vapour in the air, streams and rivers, lakes, seas and oceans.

Hydrosphere
01-10	Waterless: This world is completely deprived of water. Bring your own bottles.
11-20	Parched: This world Has some water but it is hard to locate and make use of. Perhaps all of the planet’s moisture is vapour in the air which must be farmed, or held in reservoirs deep underground and must be mined.
21-35	Arid: This world is mostly dry, having large desert landmasses, infrequent rainfall, and a peppering of oases. There is also usually a substantial water table underground which can have wells dug into it. There will be some small seas and oceans.
36-55	Average: This world has appreciable oceans, seas, lakes and rivers, and gets frequent rainfall, but also sees its fair share of inland deserts.
56-70	Damp: This world has swollen seas and oceans, with a high sea level resulting in vast inland seas. The broken-up continents get average to high rainfall, but soak up the moisture like a sponge, making it damp year-round.
71-80	Moist: This world has enormous oceans, a ton of rainfall, permanently sodden ground, and likely something big, toothy and tentacle-y lurking in those bogs and jungles.
81-90	Watery: This world is mostly ocean, with only a few island landmasses and microcontinents.
91-100	Aquatic: This world is one giant ocean, with no land whatsoever. Any settlements will have to take the form of underwater bubble-towns, drifting space yachts, or flying cloud-cities.

Temperature:

The mean temperature of a planet is one of the most significant deciding factors on how much shelter and technological assistance humans require to comfortably survive there. Temperature is always given as a range, as there will invariably be variations from equator to poles, and through the seasons.

Temperature
01-05	Bitter (-201°C/-330°F or lower): As cold as it gets. Maybe too cold for an atmosphere. Only the best heating and most complex equipment can keep the habs habitable. Going outside means flash-freezing and becoming part of the icy terrain.
06-10	Cold (-200°C to -101°C/-328°F to -150°F): Chances are, this world is made of ice, and any 'oceans' are either rock-solid, or not water at all. Giant heating networks and sealed structures are a must. If you find yourself outside, you'd better be wearing top-of-the-line protective equipment. Any sad sod finding himself outside without at least 23 parkas lasts a number of rounds equal to their toughness bonus before re-enacting the end of The Shining.
11-20	Chilly (-100°C to -41°C/-148°F to -42°F): Cold, but not uninhabitable. Sealed buildings are still a good idea, but smaller heating systems should work just fine. Going outside requires exceptionally warm clothing but this planet is still likely to be inhabited in numbers larger than a few outposts. If unprotected, you'll last a number of rounds equal to your toughness bonus, after which you gain +1 fatigue until unconscious. Death follows in one round.
21-35	Frosty (-40°C to -11°C/-40°F to 12°F): Tundras and snowbound taigas abound, but the settlements only need minor tweaking -- small windows, thick walls, the usual. If unprotected, you'll last a number of minutes equal to your toughness bonus, after which you gain +1 fatigue until unconscious. Death follows in one minute.
36-60	Average (-10°C to +30°C/14°F to 86°F): Humans are comfortable in normal clothing and need only the most basic of shelters to survive. Honestly just walk outside, chances are it'll be within this range.
61-75	Warm (+31°C to +50°C/88°F to 122°F): Depending on moisture, this world may either be a baked desert, a steamy jungle, or even a storm-wracked archipelago. Architecture will require plenty of cross-breeze. If unprotected, you'll last a number of minutes equal to your toughness bonus, after which you gain +1 fatigue until unconscious. Death follows in one minute.
76-85	Tepid (+51°C to +100°C/124°F to 202°F): A world on the edge. Any hotter, and any water will just boil away. If outside and unprotected, you'll last a number of rounds equal to your toughness bonus, after which you gain +1 fatigue until unconscious. Death follows in one round.
86-90	Hot (+101°C to +150°C/204°F to 302°F): Any water has long since boiled away, leaving this a parched or waterless world. Vast power networks and strong construction are required to keep any sealed settlements reasonably cool. If you find yourself outside, you'd better either be wearing top-of-the-line thermal protection. Otherwise, you'll last a number of rounds equal to your toughness bonus before boiling alive like a clam.
91-95	Roasting (+151°C to +300°C/304°F to 572°F): A scorcher, a tortured wasteland, an oven, where exposure and spontaneous combustion are synonymous.
96-100	Searing (+300°C/+572°F or more): Fire tornadoes and acid rain! One of the most extreme environments imaginable. You can forget about any kind of life that's not inside a liquid nitrogen and ceramite bunker. Unless you're inside said bunker, or are part dragon, you're gonna burst into flame instantly, no matter what you're wearing.

Terrain:

Some planets have a single dominant terrain type, a particular model that describes all of the land to be found on the planet. Other planets have more than one terrain present. Roll on the first table below to determine how many terrains the planet has, then generate each on the second table.

You can divide a planet between different terrains by having more than one landmass with a terrain each, or simply divide a landmass into regions of each terrain. You could even overlap and mix different terrains. Exactly what the terrain will look like will depend on other factors, like the temperate and hydrosphere of the planet. You must decide yourself how the terrain manifests when combined with the other planetary traits.

Gas Giants do not roll here as they have one terrain - gas clouds - whether or not something lies in the middle and what that might be is up to GMs discretion

Climate:

Created by the combined effects of the planet’s qualities, such as terrain, temperature and hydrosphere, the climate is a brief description of the prevalent conditions on the surface of the world. You will have to look at the contributing factors, imagine how they will interact, and give a brief description of what it is like on the planet. If you want the planet to have climactic variations, maybe for different regions, or through changing seasons, describe them here.

Native Flora and Fauna: If you wish, you can create the details of any native plant and animal life on the planet. Doing this can breathe some personality into a planet, bring it alive and make it distinctive from the millions of other planets in the Imperium.

Countries and Continents: How is the planet divided? Is the entire population united as a single political body, or are there rival or friendly factions or countries? Does land on the planet form a single mass, or does it form continents divided by oceans? These are details that you must decide based on the other features of the planet and the requirements the planet has to fill in your campaign.

Population:

The population of a planet in the Imperium can vary from a few dozen settlers or scientists on a frontier world up to the billions on a hive world.

Note that the Imperium does contain worlds with a population higher than that possible on the following table. The reason for the maximum on this table is that Dark Heresy is set against the backdrop of the Calixis Sector where the capital of Scintilla has, at 25 billion, the largest population in the sector. If you are generating a world that is to be set outside of the Calixis Sector, you may wish to extend or modify this table to create even larger populations.

The roll to determine the population of a planet gets two modifiers applied, based on the class and size of the planet.

Society:

Although all planets of the Imperium are beholden to the authority of Holy Terra, the Emperor cares little for how any individual planet is organised. Different social structures exist, and even within each of the broad definitions on the table below there can be variance and variety. You can define the politics and social structure of the planet as broadly or as narrowly as you desire or is required.

Obviously the types of society on the following table contain certain options that are more compatible with certain types of planet than with others. For example, a forge world will almost always have a Religious (Machine God) society, but very few, if any, other worlds will. More than with any other section of planet generation, the GM should consider rejecting unsuitable rolls, or simply selecting the most suitable option. If the planet has more than one country or continent, you can even have different society types playing against each other for dominance, like a feral world being made up of separate tribes, a feudal world having competing kingdoms, an industrial era world having separate nations or a civilized world having competition between different agencies and noble families. However, all must bow before the Administratum, and rights and provenances of citizens, nobles or else matter little if the Imperium doesn't receive its fair (the law requires that we state this) tithe, the Lex Imperialis is not obeyed, the Imperial Cult or its approved local form or the Machine Cult of the Mechanicus is not properly obeyed, then the lives of the rulers of politically disunited worlds or the Planetary Governor(regardless of whether they are a king/queen, dictator, elected official or a puppet to the power cliques)'s in a one world government and its factions are forfeit.

Society Type
01-08	Democracy: The government is run, at least on paper, on the principals of civil rights, freedom, and equal treatment and representation under the law. The population is responsible for electing their leaders and representatives, and for making important civic decisions. In addition, the government is often divided into three codependent branches: Legislative, administrative, and judicial.
09-17	Elected Dictator: The population or a designated body politic elected a man into the role of dictator, who then holds absolute power. Their will is law, the law is whatever they will. A dictator often has a group of advisors, and an administratum for day-to-day management, but in the end Dear Leader's decision is final.
18-26	Hereditary Dictator: The role of dictator is hereditary on this planet. When one person retires, a designated successor, usually a close relative, inherits their position. The successor holds absolute power over the law and their people upon coming of age. This transition is not always peaceful, and rarely seamless.
27-35	Tyrannical Dictator: The dictator has illegally seized power, and often rules with a bloody fist as they purge or 'disappear' the planet's dissidents, political enemies, scapegoats of the day, and anyone who poses a threat to the tyrant's ambitions. This brand of leadership can be the result of a warlord, a particularly psychotic heir, or even, distressingly often, a rogue democratic leader who played the long game and finally made his move. After all, power corrupts, absolute power corrupts absolutely, and is absolutely sought by the absolutely corrupt.
36-44	Elected Monarchy: The world is ruled by a monarch who, while ruling by fiat, is bound by a written constitution and a governing body, with the power to veto any declarations made that violates said constitution. Here, the monarch is elected by either the governing party, or by the people at large.
45-54	Hereditary Monarchy: The world is under the rule of a long line of monarchs, who pass the crown from generation to generation by a complex code of inheritance. The monarch is, however, limited by the constitution and the governing body, whose job it is to keep the monarch in check. Results may vary spectacularly.
55-63	Military Junta/Dictatorship: The world’s culture is either built around a military cause, or there have been events in its history which caused a great demand for military action and organisation. Either way, society is ruled by the military. Rather than noble or bureaucratic rank, Military rank is the position of highest political authority. Everything is arranged and run in a military fashion. The Imperial Guard (and/or the Imperial Navy) have major influence here.
64-72	Religious (Local): Planetary society has either been built around, or founded because of, a local religious sect. Or events have brought the church to the fore of all politics. This religion functions as the planet's government, and everyone must follow, or at least not bad-mouth, the religion. Depending on the religion's origins and compatibiity with the Imperial Creed, it is likely to have a close eye kept on it.
73-81	Religious (Ministorum): Live for the Emperor, Work for the Emperor, die for the Emperor. The Ecclesiarchy, the state church or the Imperium of Man, functions as the planet's government, making sure everybody, top to bottom, follows their branch's interpretation of the Imperial Creed. Or at least aren't spouting HERESY!!
82-90	Religious (Machine God): The Church of the Machine God functions as the planet's government, and makes sure all the trains run on time. Obviously, the default on Forge Worlds, and other worlds governed by the Adeptus Mechanicus.
91-99	Oligarchy: On this world, a small body of wealthy people, not necessarily of noble birth or having military, religious or bureaucratic rank, rule the area. They may be merchants, artisans, or some other type of guild members, but whatever their origins or source of wealth, they keep their authority only through that wealth and the fact that they finance society from their own pockets. A world producing an important specialty good will see the Imperium backing those with knowledge and means to make it (possibly and preferably infintely long) over other power cliques or alternatively a rich class may have already been present in such a scenario and the Imperium saw fit to retain it. The Planetary Governor will either be a puppet of the guild/society/mafia council or be its most powerful member.
100	Direct Control by the Administratum or Offworld Appointed Goverment: This world has direct and constant control by the overall Imperial bureaucracy or a direct representative of it as, possibly due to being a strategic location making the Imperium unable to trust its important governance to the locals, its status as a sub-sector or sector capital or having been recently colonized, conquered, (re)discovered and forcibly integrated or (re)discovered and peacefully integrated (in the latter case, it maybe that a planet is in a lower tech level that the Imperium saw fit to increase due to a benefit or because a politically divided but imperial accepting political class needing a neutral arbiter of power before settling into the new form).

Economy:

The economy of a planet is a description of how the people of that world manage their resources and finances. Look at the important contributing factors form the other aspects of the world determined in this process (class of world, population and society in particular), think about your own ideas for the world and the function you wish it to fill in your campaign, and note as many points as you can, or desire, about the planet’s economy.

Examples of detail you could give are: What is the local currency called? Do imports from other worlds get paid for in cash or simply a trade value to be swapped directly for exports? How extreme is the gulf between the poor and the wealthy on the world? How much does wealth dictate about lifestyle and opportunities on the world? This is an example of an area where the GM and players can go into as much detail as they wish, or simply create only the bare essential facts.

Exports: Decide what the planet produces that will be valuable on other planets. The produce of a planet is traded to merchant captains who ship it off across the stars.

Imports: Whatever the planet is in need of is brought to them by the merchant captains and traded for exports.

Here is a chart of trade goods for exports and imports. Keep in mind that a planet could have unique or unusual goods not on the list, or that some planets would find it difficult if not impossible to produce certain goods at a surplus. Roll D10 or choose.

Trade Goods	Common Goods	Luxury Goods
1.Agriculture: Plant based food. Fruits, vegetables,fungi, algae, anything grown and edible. Can also include spices and herbs. Must be export if agri-world.	Basic staple foods, such as wheat or rice. Algae chips, bread, anything cheap.	Exotic fruits, rare mushrooms or pungent spices.
2.Animal Products: The hides, flesh, bones and byproducts of fauna can have a multitude of uses. Must be export if agri-world.	Processed grox meat is many a citizen's favorite meal. Eggs, fish and milk can all be plentiful depending on the planet's biome.	Exotic hides for ostentatious coats, bones to make regal tool handles, and the most succulent meats to dine on after a long day of oppressing Imperial subjects.
3.Minerals: Rocks from the ground that have value. Used in construction, technology, currency or decoration. Must be export if mineral world.	Basic materials for the construction of buildings, machines, etc.	Valuable and rare gems, precious bullion or marble.
4.Lumber: The body of a tree, used in construction of buildings, furniture, gun stocks and more.	It may be half rotten or break from a stiff breeze, but it's plentiful and takes less time to grow than the average lifespan of a guardsman.	Wood of a unique color or with peculiar qualities makes for fine lawn chairs.
5.Weapons: Tools made for putting holes in people. Either require contact with the target or fires projectiles.	Swords and knives, gunpowder firearms, nothing more advanced than the humble lasgun.	Fancy alloys folded over a thousand times to produce rapiers of exceptional quality, or powerful and arcane weaponry like meltas or plasma guns. Maybe the planet's culture has a unique and crazy weapon found only there?
6.Vehicles: Deliver people from point A to point B.	Large civilian transports designed to transfer citizens from their manufactoria shift to their hablock.	Luxury vehicles and custom craft to cruise in style.
7.Fuel: Generates power, which is released as heat, light or electricity.	Coal, oil, and promethium laced with local contaminants.	Highly potent promethium that can burn twice as many heretics with half the amount. Efficiency is loyalty!
8.Spacecraft: A vehicle capable of flying through the void of space. Those without warp drives cannot leave the system but are much cheaper than those with one.	Cheap intrasystem crafts, mass transports or frigates to bolster Imperial fleets.	From the personal craft of noble families to cruisers or even battleships of the Imperial Navy.
9.Alcohol/Drugs: Alters the mental state of the user, usually to create a sense of euphoria or ecstasy, though long term effects may be unpleasant. Alcohol is typically drunk, while drugs can be smoked, snorted, consumed or injected.	Cheap swill or chemicals that will tear up your guts worse than an enraged grox. You're better off drinking unrefined promethium.	The finest wines in the galaxy, usually only available for a limited season. Or maybe hookah's are all the rage among the nobles?
10.Contraband: Shit The Man doesn't want you to have. In a totalitarian, theocratic regime like the Imperium, there's a lot that can fall under this.	Illicit chems or texts that speak out against the Imperium's rule.	Scandalous works and dangerous knowledge that shed light on things man was not meant to know. Xenotech is in incredibly high demand by the elite; while anyone caught with such heresy is to be executed, some secrets can bring a fate worse than death...

Conflicts:

Decide if there are currently any violent conflicts underway on the planet. This could be a civil war between rival factions (such as contenders with equal claim to the throne, a trade war, or a popular uprising,) a struggle to fight off invading xenos forces (or even to conquer the native xenos!), a war against insurgents or terrorists, or any other type of conflict you can think of taking place on the world.

This is one of the details about the world that should be discussed between the GM and the players to create the right type of environment and mood for your game, or decided on by the GM as a suitable backdrop to their scenario or campaign idea.

Defences:

These are the planet’s local defence forces, always present and alert, against mankind's many enemies, both foreign and domestic. These defences do not include any Imperial Guard or Navy forces that may be sent here by the larger Astra Militarum. The forces that can be mustered in defence of a planet and its settlements come in a few different forms, which are described below:

Enforcers:	The local law enforcers and security forces.
Militia:	Part time soldiers, who have civilian jobs but can be called upon to fight when required.
Standing Army:	The normal full time, fully trained warriors of the planet. Usually known as the Planetary Defence Force (PDF).
Armoured Force:	Any tanks and APCs.
Titan Force:	Some worlds have mighty titan war machines stationed there permanently.
Private Army/Armies:	Wealthy people/organisations can have their own private armies.
Naval Force:	Ships belonging to the Imperial Navy that are usually stationed in orbit.
Orbital Station(s):	Space stations with defence weapons, like lasers and missiles.
Missile Silos (planet):	Missile silos that can launch missiles over the surface of the world.
Missile Silos (orbital):	Silos with the ability to launch against ships in orbit.
Defence Lasers:	Huge laser batteries that can fire on orbiting ships.
Mercenary Force:	Hired muscle, brought in to fight for money.

To determine what forces are present on a world, first find the class of world on the tables below, and the three pieces of information given for each type of force for that world. The first bit of information is a percentage chance of the planet having that type of defence force present: simply roll a d100, and on a result equal to or less than the number given, the planet has that type of force present.

The second bit of information is what dice to roll on the FORCE SIZE table to determine what size of force of the given type is present on the world. The third bit of information is what dice to roll on the FORCE QUALITY table to determine what quality that force is, if it is present on the world. Simply make all of these rolls for each type of defence force and record the results.

Imperial Guard Recruitment:

Decide whether the world has a tradition of supplying Imperial Guard regiments to the Imperium. How many regiments, if any, have been founded on this world? Is there anything about these Guard regiments that makes them distinctive or noteworthy? These are details that must be decided by the GM/players, again to add flavor and distinction to the world. You can also add if the planet is a Adeptus Astartes homeworld, or some planet specific things like Titan Legion for Forge Worlds. İt may also have a Schola Progenium.

Contact With Other Worlds

The Immaterium allows travel between any world given proper preparation and navigation, but there exist relatively safe, stable, and high-traffic warp routes between populated planets. Note which, if any, stable warp routes radiate from the planet, and to what other planets they lead.
