After his experiences battling the demons Marrowit and Maries, Jez is convinced he can handle anything. All that changes when he receives a visit from Sariel himself, lord of all the Shadowguard. The seven pharim lords are among the most powerful beings in all of creation, and one of them is missing. No pharim permitted to interfere in the business of another, but that restriction doesn't apply to Jez. He and is friends must discover what could've happened to one of the most powerful beings in the universe.

Sharim is gone, driven into the abyss, from which there is, supposedly, no return. Jez isn't sure it will last though, and after months of study, he discovers the truth he'd always suspected. There is a way for Sharim to escape, and though the human demon doesn't know the way yet, he knows where to find that information. To stop him, Jez and his friends must go to a place mortalkind was never meant to walk and travel to where even pharim fear to tread.

The fabled Library of Zandra is now in the hands of the mages of the Carceri Academy. As they uncover its secrets Sharim beings to move, marching his demonic forces south and destroying everything in their path. Jez must use his full power, both as a mage and as the Baron of Korand, to oppose him, but even all of his strength and authority may not be enough to stop Sharim's demonic army from conquering the land and claiming the Carceri Academy itself.
