Setting.
All of the "Summon Night" games take place in Lyndbaum, a world similar to medieval Europe with the inclusion of modern factories and railroads, placing "Summon Night" in a steampunk setting. Lyndbaum is surrounded by four other worlds: Loreilal, the land from where mechanical creatures come; Silturn, the land of yokai; Sapureth, where angels and demons live; and Maetropa, from where half-humans, magical beasts, fairies and other mythical creatures hail. Besides those four there are also countless other worlds, including our world (the "real" world) where the main characters of the first game are transported from. Certain boundaries separate the worlds from each other, making the various summoning techniques the only way to transport things between them.
