Welcome to Theria, a dark medieval world where monster girls roam and the margins for survival are razor-thin. In the city of Aethelgard, you are the Assessor. A mid-level bureaucrat with the power to ruin lives or look the other way. Armed with nothing but a ledger, a silver badge and a pendulum that detects the world's newly awakened, illegal magic, you walk the line between duty and desire. Your routine assessments end up dragging you into a dangerous web of criminal syndicates, forbidden magic and powerful women who know exactly how to make a man compromise.

This is a story about a tired, corruptible man trying to survive a harsh world.
