Unwillingly forced to serve as a human trial for a crazy alchemist experimenting with time travel, Edward Elric finds himself standing across from Truth in the moment it takes his leg from him. Armed with the knowledge of what's to come and burdened with guilt for the choices he'd made as an adult, Ed sets out to fix every mistake he ever made and save every life they ever lost, no matter what it takes.

Edward grabs Marcoh’s arm and says, “That stone – what can it heal, exactly?” The old man’s eyebrows rise to his forehead, and he looks like he already knows the answer when he goes, “Why do you ask, Edward?” There's no metallic footsteps so there’s no way Al’s close enough to hear them. “I’m sick,” he admits after another moment of deliberation.
