The Necromancer's Gambit

Knight, the sheriff of the local magical government, or "the Gambit," is called to recover a mutilated body, tainted with magic and dumped at a popular haunt. When the corpse is identified as a close associate of the Gambit, he suspects a larger conspiracy threatening the fragile peace amongst the city's magic-wielding factions. As more bodies fall, Knight finds himself fighting for the lives of those he cares about.
