The '''Demonicus de Zoltun Kulle''' is a [[Vizjerei]] Horadric tome of demonic knowledge, primarily listing information about different demons. It was written by one of the founding members of the [[Horadrim]], [[Zoltun Kulle]], who later ventured down the path of evil. It's unknown how many copies exist of this book, but [[Abd al-Hazir]] is in possession of one known copythese texts.

The This book is used by Abd al-Hazir as a corroborating cross reference, as the [[Vizjerei]] tomes which cover similar topics are likely full of incorrect misleading information, or blatant lies. The texts written by the Vizjerei were often used as self-serving propaganda aimed at whitewashing heinous deeds committed by the [[mage clan]] during the [[Mage Clan Wars]]. Abd himself al-Hazir mentions the [[Khazra]], as an example and they are likely written about in Demonicus de Zoltun Kulle, but how their true history would be was covered up to portray them as lieutenants of [[Baal]].

Only a one section of Volume 5 is known has been seen so far: ===Fallen Ones <small>(Nanus Improbus)</small>===As hard as it is to believe, the [[Fallen One|fallen one]]s were once exalted demons of the [[Burning Hells]]. They served as [[Azmodan]]'s hands, performing acts that he would not, could not involve himself in. They were the instrument of Azmodan's first failed attempt to usurp power from [[Diablo]] and his brothers, and after that failure, the fallen were subjected to the full wrath of Diablo. They were twisted into small, ridiculous imps, in contrast to their previously powerful forms. Moreover, if they expected Azmodan to reverse their condition, they were sadly mistaken. The infuriated Azmodan held them responsible for the [[Prime Evils]]' continued reign, and so he left the fallen in their new bodies, where their degradation would serve to amuse him for all eternity. Their failure provided him with the information he required to succeed in dethroning Diablo and his brothers - the event now known as the "[[Dark Exile]]" - but that fact did nothing to soften his heart toward the fallen.  When unleashed upon our realm by their master, Azmodan, these impish terrors display a tendency to swarm like flesh-hungry locusts, and they have been known to tear apart a sleeping village in minutes. Small of stature and simian in appearance, these creatures possess surprising strength and unnatural agility. Other than feasting on human flesh, the only act that gives these unspeakable horrors pleasure is breeding; hence the tendency to encounter them in large packs.  However, due to their small size, cowardice appears to be one of the chief features of this species. They quickly retreat when one of their brethren falls in battle.

==Trivia==Check out ::However, due to their small size, cowardice appears to be one of the [[Diablo I Manual]] for other similar in-world writings. There you can also read the "cover-up" about the [[Khazra]] (Goatmen) etcchief features of this species. This is They quickly retreat when one of course a handy [[retcon]] by Blizzard.
