Plot Elements

 * Long ago, the continent of Archanea was invaded by the Dolhr Empire, led by the Shadow Dragon Medeus.
 * Anri, a youth from Altea, defeated the Shadow Dragon using the divine sword Falchion.
 * The Kingdom of Archanea was restored and the world entered an era of peace; however, 100 years later, Medeus is resurrected by the evil wizard Gharnef, who has conquered the mage-state of Khadein. The two form an alliance with the kingdoms of Macedon and Grust in order to conquer the world.
 * Cornelius, the king of Altea and successor of Anri, takes up Falchion and leaves to battle them, leaving his son Marth and daughter Elice in the care of a bastion manned by Altea's ally, Gra.
 * However, Gra betrays Altea to Dolhr; Cornelius is killed, Falchion is stolen, and Elice sacrifices herself so Marth can escape.
 * Accompanied by a handful of knights, Marth takes refuge in the island nation of Talys.
 * Several years later, Marth repels a pirate invasion of Talys, leading its king to conclude that he is ready to battle Dolhr; he sends Marth out with several of his most trusted men and his daughter, Princess Caeda.
 * Marth first rescues the kingdom of Aurelis and enlists the aid of its king's younger brother, Duke Hardin and his retainers.
 * Marth meets Princess Nyna, the last survivor of the Archanean royal family and leader of the resistance against Dohlr.
 * Nyna gives Marth the Fire Emblem, a legendary treasure given to the hero destined to save the world. The two march to Archanea and free it from Grust's grasp.
 * After briefly invading Khadein in search of Falchion, Marth retakes Altea.
 * Mrth learns that his mother was killed in the invasion and that Gharnef is holding Elice prisoner.
 * Marth next battles Grust and their top general, Camus, who rescued Nyna from execution at Dohlrian hands; he chooses to uphold his honor as a knight of Grust, and Marth is forced to defeat him.
 * Marth is contacted by Gotoh, a wise old sage, who informs him that Gharnef wields the tome Imhullu, making him invincible; the only thing capable of defeating him is the magic of Starlight.
 * Gotoh sends Marth to the Fane of Raman to find the materials needed to create Starlight; he also rescues the divine dragon, Tiki.
 * Marth then invades Macedon and deposes the tyrannical King Michalis with the aid of Michalis' sister Minerva. There, Gotoh reforges Starlight.
 * Marth invades Khadein once more, defeats Gharnef, reclaims Falchion, and rescues Elice. He then makes his way to Dohlr, battles, and defeats Medeus, returning peace to the land.
 * Caeda and Marth declare their love for one another.
