Welcome to the Salt Mine, a black ops agency that monitors and manages supernatural activity from its subterranean headquarters in the deep mineral mines of Detroit, Michigan. When magic is real, someone has to keep it in check. When jammer Slashy Sadie of the Detroit Roller Derby is found dead in her loft, Detroit PD is on the case. After all, what's supernatural to being stabbed in the chest? That is the burning question Agent Teresa Martinez-codename Lancer-must answer as she takes over esoteric surveillance of Detroit in Fulcrum's absence. Will the Salt Mine subvert the plots in motion before it's too late?
