A homunculus manages to breach impenetrable Fort Briggs, and the Elric brothers discover a terrible alchemical secret that penetrates every corner of the world as they know it! Meanwhile, Major Kimblee and a ruthless General Raven make Major General Olivier Mira Armstrong an offer she can't refuse... Whose side is she on, really? And how far is she willing to go?

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 brother and himself...the legendary Philosopher's Stone.
