The home of Pokemon, as well as Pokemon
trainers like Ash. It is a large castle, where the dueling elite live. Pokemon are a unique species, they are unusually resistant to darkness, but if they are turned to heartless, they become shadow pokemon. Deep below the castle are the sacred catacombs, home to the temple of legends, with magic tablets of the legendary pokemon.
