Death stalks Corvis by night, and only an unlikely group of heroes known
as the Black River Irregulars can put an end to the terror. The
labyrinth of tunnels beneath Corvis is home to some of the city's worst
criminals, but now even these hardened thugs have reason to watch their
step in the dark, shadowy undercity. Death moves in that darkness,
leaving behind a trail of horribly mangled bodies. The identity of the
killer is a mystery, although his calling cards - brutally savaged
corpses and a distinct, repulsive odor - are constants at each bloody
murder scene. As business falters in the wake of the murders, the shady
owner of an illegal gambling hall hires a ragtag group of mercenaries
and adventurers to find the killer and end his reign of terror. Among
these mercenaries are the trollkin bounty hunter Gardek Stonebrow, the
enterprising mechanik and soldier Colbie Sterling, the investigator and
arcanist Eilish Garrity, and the skulking alchemist and thief Milo
Boggs.
Together, these four must work to overcome their differences, track down
a killer, and end the murder in Corvis before one of their own becomes
the next victim.
