Dragon's Crown is set primarily in the Kingdom of Hydeland, in the same fantasy world of GrimGrimoire and Odin Sphere, taking place within a different timeframe and location of the world. The game's world possesses vast labyrinths and catacombs that lay beneath the civilization, and fantastical monsters that stalk the darkest and most desolate forests. The plot revolves around a legendary relic, the Dragon's Crown, and the quest to retrieve it. A mysterious coven of magic-users with influence in even the highest levels of government seek the treasure and have used their sorcery to link long-forgotten ruins, dangerous labyrinths, and many other areas together in order to search for it. Players must take up the role of one of six adventurers charged with retrieving the crown before those who would use it for their own sinister purpose, as well as search for treasure and riches of their own.
