Fullmetal Alchemist: The Conqueror of Shamballa

Edward Elric is stranded in 1923 Munich, separated from alchemy and from Alphonse after sacrificing everything to save his brother. He studies rocketry and searches for a path home while political extremism grows around a Germany still scarred by war.

In Amestris, Alphonse has restored his body but lost key memories and continues studying alchemy in hope of finding Edward. Their worlds begin drawing dangerously close when people on Edward's side seek a gateway to the place they call Shamballa.
