'Cherubael threw itself at me as far as it could before the chains went taut and snapped it back. Its scream of rage and malice shook the cell and blew every last one of the candles out.

Gregor Eisenhorn, once one of the most zealous and puritanical young inquisitors, has long since discovered that there is a fine line between the utilisation of proper mystical resources in the protection of mankind - and dabbling with the corrupting forces of Chaos!
When an old friend is no longer able to tolerate his methods, leaving in disgust, and then a monstrous foe arises of Eisenhorn's own creation, the aged inquisitor is left wondering which side of that line he is now on. And worse, which side he wishes to be.
