Sorcerer

“The dominion of Man the Animal is done. The age of Man the Psyker has just begun!”
— Heretic Thaylon Sol, final words
Some psykers choose the path of damnation in their quest for power.
Heeding the whispered lure of Daemonic promises, they give up
their souls in return for secret knowledge, raw power and mastery
of things that man was not meant to know. These psykers embrace
the Dark Gods as their lords and masters, making vile pacts to
further their own depraved avarice. They are despised and feared
for their unnatural practices and Daemonic taint. The Inquisition
regards these sorcerers as highly dangerous foes, for they often act
as doors through which Daemons may enter realspace.
