More info: Mystara is a campaign setting for the Dungeons & Dragons fantasy role playing game. It originated as the Known World, a semi-generic setting used in early adventure modules, first mentioned in the Module X1, Isle of Dread, which was expanded upon in various D&D modules and sources, particularly a series of Gazeteers.
