When Harrowstone Prison burned to the ground, prisoners, guards, and a host of other vicious madmen met a terrifying end. In the years since, the nearby town of Ravengro has shunned the fire-scarred ruins, telling tales of unquiet spirits that wander abandoned cellblocks. But when a mysterious evil disturbs Harrowstone's tenuous spiritual balance, a ghostly prison riot commences that threatens to consume the nearby village in madness and flames. Can the adventurers discover the secrets of Harrowstone and quell a rebellion of the dead? Or will they be the spirit-prison's next inmates?
