Editing Demonomicon of Iggwilv (section)

==The Grimoires==
The titular Grimoires are a set of six books written by Iggwilv containing her observations, understandings and strategems developed over centuries of studying the [[Abyss]] and the [[demon]]s that dwell therein. These books abound in abyssal and demonic lore, outline practical methodology when it comes to [[demon]] summoning, detail various spells Iggwilv invented to augment her skills as a conjurer, and usually contain the Truenames of various demons. The specific contents of each grimoire vary, mostly in terms of what Truenames are present. Not helping the matter is that the Demonomicon has been copied by other wizards and abyssal witch-priests, creating diluted versions that have scattered across the cosmos.

The very first appearance of the Demonomicon is in the [[Advanced Dungeons & Dragons]] adventure ''S4: [[The Lost Caverns of Tsojcanth]]'' for AD&D 1st edition, where it is one of seven tomes found near the coffin of Iggwilv's (now-)[[vampire]] daughter, a warrior-woman named Drelnza. Later sources will claim that this is specifically the first volume of the six, having begun its life as [[Zagig]]'s "Tome of Zyx" before Iggwilv stole it and began appending it with her own studies. This first version contains truenames, rules for magical circles and diagrams, and a bevvy of new spells; the [[cleric]] spells of ''Abjure'', ''Exaction'' and ''Henley's Digit of Disruption'', and the [[wizard]] spells of ''Dismissal'', ''Dolor'', ''Ensnarement'', ''Banishment'', ''Torment'' and ''Binding''.

Another Iggwilv-written grimoire, "Lore of Subtle Communication", is namedropped in Dragon #82's "Spells Between The Covers". It's unclear if this is part of the collective sextet that make up the Demonomicon, or if it's an entirely different book.

A third grimoire, "Iggwilv's Nethertome", is mentioned in Dragon #225's Campaign Classics: "Three Greyhawk Grimoires"; again, we don't know if this is or isn't part of three Demonomicon proper. We do know that it includes a long treatise on the [[Blood War]], chapters detailing the [[Abyss]], including safe travel and places to avoid, a discussion of demon psychology, and a bevvy of spells. Most of these are common Conjuration-related spells - Protection from Evil, Contact Other Plane, Conjure Elemental, Invisible Stalker, etc. However, it also has two new offensive spells pioneered by Iggwilv; Lightning Cage (like a Forcecage, but with lightning) and Timeless Sleep (traps the victim in temporal stasis).

Third edition finally saw a "Demonomicon of Iggwilv" article in Dragon #336, which converted the in-universe grimoire into a set of lesser artifacts. As well as converting the unique spells from back when it first appeared in the Lost Caverns of Tsojcanth, the grimoires themselves are magical; they grant the bearer +5 caster level when casting spells with the "Evil" keyword, as well as bonuses to various skills, and each has 5 blank pages that can be used as the focus for spells like ''Magic Jar'' and ''Trap The Soul''.

Finally, Dungeon #151 contained the adventure "Iggwilv's Legacy", a massive sequel-cum-revamp of the original Lost Caverns of Tsojcanth adventure.
