The Wretched

From publisher blurb: The Wretched have origins of horrific scientific and magical experimentation. Vindari scientists using a combination of bhriota rituals, romni legends, and galvanizing equipment reanimated the corpses of fallen military soldiers. The goal was to create a more controllable undead, one that could be trained to fight the Spawn of the Old Ones and spare the lives of living people. Instead... they got something else.
