However, their ritual went horribly wrong: Edward lost his leg, while Alphonse lost his whole body. Wanting nothing but to bring his brother back, Edward sacrificed his arm to bond his soul with 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.
