It is 1923 in Munich. Two years have passed since Edward ElricÂ’s sacrifice ripped him out of his world and into ours, separating him from his younger brother, Alphonse. In that time, EdÂ’s continued research into rocketry has allied him with Alphonse Heiderich, a fellow researcher who oddly resembles EdÂ’s brother. Back in his own world, Al has been unlocking new secrets of alchemy and gaining incredible powers, all in the hopes of finding Ed. Battling the occult, ideological extremists, and monstrous Homunculi lurking in the shadows, can the brothers find a way to reunite without causing chaos and bloodshed? What will happen when the world of alchemy and the world of modern science collide?
