Vassago

One of the most powerful Demon Lords, Vassago's domain extends to the the earth, memory, and the past. He also has dominion over the undead, and he uses ancient secrets long lost to mortals to create his preferred servents: The Fleshcrawlers and Memory Eaters. Vassago knows the locations of many powerful artifacts, and will barter this information in return for the services of various loremasters and mages. Ironically, Vassago was behind the creation of the Voidgem which later imprisoned his father, Kuthian. Some whisper that he was also behind the creation of the Four Swords, powerful relics which have seen many hands over the years. Vassago teaches, "The domination of the future lies in the memories of the the past."

Domain
Vassago is sealed in the 7th layer of the Abyss. This land is a never ending tomb, where sarcophogi line the walls. The layer itself is hungry for more victems, and earth sucks anyone standing on it into it's depths. Stay in one spot too long, and the unlucky adventurer will find himself in one of the sarcophogi. In the center of this hellish land is the Unholy Library, a tower which is so tall that it streches into the 6th layer, a land of mind-breaking screams. It is said that Vassago's Memory Eaters listen to the screams, and take the tidbits of knowlege they gleam from the insanity back down to their master, who dwells on the Tombthrone, in a dark throneroom beneath the Unholy Library.

Summoning
To summon an Avatar of Vassago, the basic magical circle must be drwn on the ground. In the circle must be drawn the sun, and the fangs of an animal about to devour said Sun. A First Edition book must be buried in the circle, an offering to the Unholy Library. The following chant must be chanted,

"Prince of the Realm beyond, that place beyond death and our mortal shell, where mere men can find enlightenment and walk with the gods, I, unworthy seeker of knowlege forbidden, beseech thee! Come unto me, full of unknowlable might, and walk with men! I name thee bringer of the light that is the thought! I name thee, ruler of unlife! I name thee, Vassago!"
