with fan-made material. The continent of Skothar Very little was officially developed for this part of Mystara. Ever since the Mystara product line was discontinued, fans have created their own material for this part of Mystara. The Hollow World Mystara is a hollow planet, with a habitable surface on its interior called the Hollow World. This world is lit by an eternal red sun at the center of Mystara, and serves as a "cultural museum," preserving the societies that have become extinct in the outer world. The existence of the Hollow World is not, in general, known to the inhabitants of the outer world. The poles are actually huge, subtly curving holes that allow passage between the outer and inner world, although it is a long, hard trek through a cold, unlit, stormy and anti-magic area. The curvature of the holes is so subtle that explorers from either surface do not notice the transition until after it is already made, causing quite a shock for most. Moons Two moons orbit the planet. Matera is a moon much like our own, whose phases govern lycanthropy (werewolves, werebears, etc.). Only the Immortals inhabit Matera. They live in a city, Pandius, where they can meet and watch over Mystara. Patera, or Myoshima to its inhabitants, is an invisible moon that cannot be seen from Mystara. Patera's inhabitants have a culture similar to that of medieval Japan. Blackmoor Mystara (like Greyhawk) also incorporated the Blackmoor setting by placing it in the world's distant past. Blackmoor evolved from a feudal kingdom into a highly advanced civilization, using more and more powerful – and destructive — technology. It ended itself in an apocalyptic explosion so devastating that it changed the climate and geography of the entire planet. Mystara video games Five video games were set in Mystara, and they span three different genres. Order of the Griffon (TurboGrafx 16, 1992) and Dungeons & Dragons: Warriors of the Eternal Sun (Sega Genesis, 1992) are role-playing video games. Fantasy Empires (PC, 1993) is a strategy game. The plots and development teams of these games are unrelated. Dungeons & Dragons: Tower of Doom (1993) and its sequel Dungeons & Dragons: Shadow over Mystara (1996) are two arcade beat 'em up with minimal role-playing elements. These two games are among the few D&D video games developed by a Japanese company, in this case by Capcom. Novels Dark Knight of Karameikos
