Fire Emblem Echoes begins with a war happening, with Alm and Celica thrust into action. They begin their resistance by fighting simultaneously through Act 1 & Act 2, but by Act 3, they are separated into their own individual paths and storylines. As their paths continue to differ through Act 4 and they each recruit a number of followers and build their armies, their worlds will again collide to end the storyline. It is up to these two and the armies they build to overthrow the king and the evil that persists in the world. Will these old friends be able to end the war of Valentia for good once and for all?
