2000 years prior to Awakening, Ylisse was previously the continent of Akaneia.
1000 years prior to Awakening, the Fell Dragon Grima attempted to destroy the world. However, his actions were stopped by the Divine Dragon Naga, who granted the first Exalt of the Halidom of Ylisse her power through the Awakening ritual. Grima was defeated and put into a deep slumber. Because of the immense strength of the Fire Emblem, the five gemstones resting in it were removed and distributed to various countries during a time known as the Schism. Ylisse then separated itself into three separate nations, the Halidom of Ylisse, Regna Ferox, and the Theocracy of Plegia.
Regna Ferox comprises of the entire northern half of Ylisse and separated from its southern neighboring countries by a long wall stretching from one coast to another. Ferox has two rulers; Flavia, the East-Khan, and Basilio, the West-Khan. Only one of the Khans can hold sovereignty at a time, so they hold a tournament to decide who is the ruling Khan.
