Trapped on the Shadow Plane, the heroes' only hope of returning to the Material Plane is to find and destroy the mad scientist whose machinations put them in this predicament. At a creepy spacedock controlled by worshipers of a god of darkness and pain, the PCs are able to retrieve a shadow version of their starship to fly back to the asteroid where the campaign began.
Fighting past disturbing vessels piloted by shadowy fiends who want to flay them alive, the heroes arrive at a twisted place where the moans and screams of unseen beings echo through unfamiliar halls. At the center of this web, the heroes confront the evil scientist, who has been transformed through her experimentation with pleasure and pain. With her notes and the use of partially living machinery, the PCs can cure themselves of their corruption and find a way home!
