Abraxas

Abraxas was a Demon Lord who called himself the Unfathomable. An avid collector of the Arcane, Abraxas spent his days trying to amass more magic items, learn more forgotten spells, and find and create arcane talismans, goals which often brought him into conflict with Scrix, another demon lord who reveled in the magical secrets. Abraxas dwelt on the layer of the Abyss known as Death's Reward, a blasted ruin that he, through the use of illusion magic, made to resemble a superficially beautiful paradise.
