The setting of "The Legend of Zelda: Twilight Princess" is a magical, Medieval European-style kingdom. The kingdom, named Hyrule, is also connected to a parallel dimension called the Realm of Twilight, which stands in opposition to Hyrule and seeks to conquer it. When Link is in the Realm of Twilight, he sheds his form and becomes a wolf. Link is also the protagonist of numerous other games in the Legend of Zelda series, and he has appeared in other game series, such as Super Smash Brothers.
