Fire Emblem is a tactical role-playing game where players take the role of story protagonists Lyn, Eliwood, and Hector as they navigate story-driven missions across the fictional continent of Elibe. The player takes the role of an unseen tactician directing the player army.
The events of Fire Emblem take place on the fictional continent of Elibe, twenty years before the events of Fire Emblem: The Binding Blade, in ancient times, humans and dragons coexisted, but humans turned against and banished the dragons in a conflict called "The Scouring". The player adopts the perspective of a tactician who is found by a girl named Lyn. Lyn discovers that she is the granddaughter of the marquess of Caelin, Hausen. She recruits companions in a quest to prevent Lundgren, her great uncle, from ascending the Caelin throne. Lundgren had wanted to gain power by poisoning the current marquess; he also sent soldiers out to destroy Lyn and any knowledge of her as she is higher in the line of succession. Lyn eventually defeats Lundgren and reunites with her grandfather.
The following chapters revolve around the Lycian lords Eliwood, Hector and their party, which the tactician, (and eventually Lyn) joins.
