Dark Sun
A campaign setting made for AD&D 2nd edition back in '90. There are 3e conversions approved by WotC, but they were never published as books or anything. WotC recently released an updated version for 4e
Setting
The game is set in the world of Athas, a dying planet. Once full of happiness and sunshine, the planet was drained of all resources during the long and rich history the creators came up with. There is no water, no minerals, and no hope: only cannibal halflings, a lot of sand and a dying sun. The world is so fucked up it makes Mad Max's setting look like a hippie paradise. The only few realms remaining are fascist police city-states rule by wizards (all of them retarded evil, except Hamanu, who is a pimp served only by the hottest females in Urik and each day in his life is an orgy) who are no longer human at all. Beyond civilized lands everything eats everything. The best weapon you can find is the femur of your party's cleric after being eaten by something that looked like a rock and the best armor is mostly the remains of a giant roach. There are no gnomes, orcs, kobolds, or furrys because all of them where exterminated by guys who where so badass that the only explanation for their power is that they were the extradimensional offspring of Chuck Norris. They were: The Champions of Rajaat.
Races
Most of the generic fantasy races were exterminated a long time ago, good riddance!
This means no gnomes! First reason why this setting is full of win and awesome.
- Halfling - Cannibals who live in the remaining strips of forest.
- Elf - No forests for them, ha! They are desert nomads, thieving and griefing all the time.
- Dwarf - Almost typical dorfs, except they're bald and are even more fixated on their stuff.
- Mul - Half-dorfs! Second reason why this setting is full of win and awesome!
- Half-giant - Big bad meanies, with a lolrandom alignment
- Thri-kreen - Sentient mantis. Strange, scary folk. Like their elves raw.
- Dray - Horribly deformed dragon-people. Basically a failed magic experiment.
- Aarakocra - Sentient birds, for those who don't want to play anything normal, but hate bugs or lizards.
- Human - Sentient halfling, only larger.
- Pterran - Pterodactyl shamanistic retards that remind you of a certain cheesy villain from the X-men comic books.
Classes
- Clerics - There are no real gods in the setting, so most clerics worship elements or quasi-elements. Druids serve nature spirits or some other stupidity. In a desert world, summoning water elementals will get you pussy until you realize that if you level up to much you become a true elemental too. Very nasty to be drank alive for being a water elemental.
- Gladiators - You know. Like the movie. Also one of the most overpowered classes in the times of AD&D, a low level gladiator could be the personification of a certain Frank Frazzeta illustration entitled "The Destroyer".
- Bards - Most bards sing songs and boost the other party members' rolls. Dark Sun bards will fucking kill and poison you.
- Templars - Replace Paladins, but more on the police side of things to the point they are like the Gestapo in Nazi occupied France. Worship the Sorcerer King who rules their city.
- Psions - Psionics are considered accepted and normal in this setting. In fact, every PC is guaranteed to have at least one psionic power!
- Wizards - Two types exist in the setting, but everyone hates them both:
- Defiler - Evil mages, who suck out the life force of things. When they level up enough, they usually have an allergic reaction called dragon metamorphosis.
- Preserver - Mages who are not manly enough to steal life force, so they sacrifice efficiency to keep the stuff around them alive. Unfortunately for them, the commoners think all wizards are the same. When they grow up enough to be considered bad ass they turn into the manta ray like aliens from Abyss.
