Synopsis

The game takes place approximately 2000 years after the events of Fire Emblem: Shadow Dragon and the Blade of Light. In ancient times, the Fell Dragon Grima attempted to destroy the world. To stop Grima, the Divine Dragon Naga (voiced by Mela Lee) chose the ruler of the Halidom of Ylisse (known as the First Exalt) and granted them power through two magical objects: Falchion, a sword with the power to slay dragons; and the Fire Emblem, a magical shield. Using these, the Exalt struck down Grima, sending it into a long slumber. In the intervening period, the continents of Archanea and Valentia became known as Ylisse and Valm. source: wikipedia
