Are you ready to journey to Dark Worlds?

You and your friends become unwitting pawns caught up in the blunders of a mad ruler. His insane attempt to curry favor with the dread Fungi from Yuggoth results in your being teleported across space to the nightmare world of Yuggoth. The ritual keeps you alive... for now. But how long will its effects last? Your only hope is to track down the wizard Mustafo who was transported along with you, and who knows the spell of return. Unfortunately, Mustafo has been taken by the Fungi for their dire purposes and your attempt to rescue him have drawn their attention...
