In witch-haunted Arkham, a restless spirit takes possession of an innocent woman and brings havoc to all who encounter her. Inspired in part by H. P. Lovecraft's "The Thing on the Doorstep," The Revenant of Rebecca Pascal takes you to ghostly houses and sinister Arkham burying grounds, where alchemy and madness join forces with a daemonic entity aroused from beyond the wall of sleep. But be warned: to learn these secrets of the worm is to have one's sanity infected!
