In an alchemical ritual gone wrong, Edward Elric lost his arm and his leg, and his brother Alphonse became nothing but a soul in a suit of armor. Equipped with mechanical ""auto-mail"" limbs, Edward becomes a state alchemist, seeking the one thing that can restore his and his brother´s bodies...the legendary Philosopher´s Stone.
With the Day of Reckoning at hand, war breaks out in Central City. On one side, the homunculi and corrupt military; on the other, the Elric family, Ishbalan refugees, and a ragtag alliance of soldiers loyal to Major General Armstrong of Fort Briggs and Roy Mustang. While Hohenheim confronts the homunculi´s "father," Mustang finally learns the truth about Hughes´s murder. Will he be consumed by hatred and do the unthinkable?
