It is 1923 in Munich. Two years have passed since Edward Elric's sacrifice ripped him out of his world and separating him from his younger brother, Alphonse. Ed's continued research into rocketry has allied him with Alphons Heiderich, a fellow researcher who oddly resembles Ed's brother. Progress has been slow, however, and Ed has become discouraged. But when he saves a quiet Gypsy girl with the power to read minds, Ed is quickly pulled into a plot by the Thule Society and the burgeoning Nazi Party that could drag both worlds into a terrible war.
