Narnia

Narnia is the main basis of C.S. Lewis' novel series, and it's resulted film adaptations, The Chronicles of Narnia. A vast fantasy realm, inhabited by various magical creatures, ruled by it's righteous leader, Aslan, Narnia has been frequently threatened by various evil forces, including the White Witch, Jadis, and her fearsome armies, as well as the ruthless monarch, Miraz, and his Telmarine warriors, thus it sought help, through Aslan, from heroic figures, like the Pevensie family, or the future lord-to-be Prince Caspian, to defend the realm, from the villain forces.

It also appears in the villain tournaments, though in many of them, it is displayed by the presence of Jadis' domain. However, it also appears in full appearance in the second Disney Heroes vs. Villains War, as one of the main realms of the live-action universe.
