Raised as a wizard-priest in the church of the dark god Zon-Kuthon, Isiem escaped his sadistic masters and became a rebel, leaving behind everything he knew in order to follow his conscience.

Now, his unique heritage makes him perfect for a dangerous mission into an ancient dungeon said to hold the magical Nightblade, a weapon capable of slaying devils by the thousands and freeing the world of their fiendish taint.

Accompanied by companions ranging from righteous paladin to mercantile mercenaries, Isiem will lead the expedition back into shadowed lands that are all too familiar. And what the adventurers find at the dungeon's heart will change them all forever.
