Your goal is to drive back these horrors and redeem the family name. You are the heir of a former noble family, damned due to the actions of a hedonistic forebear who spent the family fortune excavating an ancient portal underneath the family estate and inadvertently releasing an untold number of Eldritch Abominations. Darkest Dungeon is a challenging Gothic Horror Dungeon Crawling RPG about the stresses of dungeon crawling, developed by Red Hook Studios.
