- "I hunger for it all: the water, the wind, the trees, the land. I will never be satisfied until it is all mine."
Created on Planet Fargett as a part of the superhuman project, Asmodeus was a success, and the people of Fargett were glad that they finally had a human that could easily survive on their world. However, Asmodeus was not too happy with the world he was on, and stole the Space-Time Laboratory, transporting it away from Fargett.
Asmodeus found himself in the Demon World, where he quickly went about experimenting on the local monsters. He also declared himself ruler of the Demon World, which the native monsters had no problem with. Noticing the portal that could lead him to Roak, Asmodeus began to plan the invasion.
At some point, a group called the Church of Sydonai began to worship Asmodeus. The Sydonaists hold Asmodeus in such a high status, almost like a god, believing that he can cleanse Roak and make it pure again. To "resurrect" Asmodeus, the Sydonaists must sacrifice a "maiden of pure blood," referring to a Featherfolk woman, and they end up choosing to sacrifice Sarah Jerand. The leader of the cult is Tamiel, a Grigori.

Eventually, Asmodeus created a super-weapon and attacked Roak, destroying the town of Durss for a "real-world example". Realizing that time wasn't on their side, Roddick and the party set off to the Demon World. They eventually got into the heart of the laboratory, where Asmodeus taunted them, claiming they were welcome to take his blood, if they could. In the final room, the party confront and kill Asmodeus, but before they could get a sample, soldiers from Fargett beamed in and stole a sample for themselves. After getting their own sample, the party left Asmodeus' corpse behind in the Demon World.
