Fullmetal Alchemist - Vol. 4: The Fall of Ishbal

The Elrics return to Eastern Headquarters to report their progress - which, as Mustang points out, is none. Ed and Al leave for the countryside to search for Doctor Marcoh, a State Alchemist who deserted during the Eastern Rebellion and is now a fugitive of the state. Unbeknownst to the brothers, Marcoh possesses secrets that could prove invaluable - if they can keep him alive. On the run from both Scar and the military, Doctor Marcoh confesses to the Elrics the reason these tragedies are happening.A decade ago, State Alchemists were called into Ishbal to end a seven-year civil war. What followed was a wave of unspeakable atrocities that neither the Ishbalans, nor the State Alchemists who committed them, can forget.
