_High Inquisitor Bronislaw Czevak was a distinguished and controversial member of the Ordo Xenos active in the Moebius Sub-sector during the second half of the 41st Millennium.
Spent much time during the 42nd Millenium as a prisoner in the Black Library.
He directs his main efforts against the Chaos Sorcerer Ahriman, who is his prime opponent and nemesis. Imperial authorities regard him at best as a Renegade in possession of dangerous but valuable knowledge, and at worst as a Heretic and Traitor liable to be summarily executed. _
