It is 1923 in Munich, Germany. Two years have passed since Edward Elric was pulled from his world in Central City, Amestris, and landed in our own. Stripped of his alchemic abilities, Ed has been working feverishly to get back to his brother Alphonse but all his efforts have
so far been to no avail. When he helps a quiet gypsy girl, however, he sets in motion a series of events that will effect both worlds.

Meanwhile, it is 1917 in Amestris. Al still has no memory of their adventures, but he is determined to get Ed back and has developed his own alchemic abilities. When strange things begin to happen in Liore and Central, though, Al receives help from an unexpected source.
Soon he, too, is caught up in a nightmare that could tear two worlds apart.
