"A video game for the Commodore 64 developed and released by Ultimate Play The Game in late 1985. It is a sequel to The Staff of Karnath, Entombed and Blackwyche, and is the final title to feature the aristocrat adventurer, Sir Arthur Pendragon.
In this final game of the quadrilogy, Pendragon is in search of the powerful yet cursed Skull. The game is a flick-screen maze-puzzle solver, where the player must walk from room to room, avoiding the dangers while trying to figure out how to pass the obstacles."
