The ruse of Winry's abduction by Scar is revealed, but a plan of rescue must still be hatched. A brutal storm is coming - one which only Alphonse Elric can brave.

Long ago, the blood of a simple slave was used in an experiment which created a strange, shapeless being. In exchange for the gift of existence, the being gave the slave a name - and cursed him with immortality.

Bound by more than blood, the Elrics have long shared joy and pain. Now, with Al wandering the frigid void - and Ed losing blood by Kimblee's hand - the mystical connection of their souls could prove fatal.

May and Marcoh's efforts to decode the research of Scar's brother yield progress, but it might be too late to prevent catastrophe. Violence is spreading across the land, and it will soon reach the northern border.

In the snowy north, the soldiers of Fort Briggs engage an invading army, and Marcoh leads an attack against monstrous Envy. In Central, an ominous and shocking secret is revealed to Olivier Armstrong.

Hohenheim and Alphonse enjoy a chance to get reacquainted. Their bond is restored with ease, inspiring the father to share his secrets with his sons - but one of them is far away and on the run.

Quiet warnings spread near and far: the Promised Day is at hand. While most will face the coming chaos with their own kind, Edward forms a new cabal comprised of human, chimera - and Homunculus.

Those who have prepared to reclaim a nation find their plans exposed. The chaos multiplies after an assassin strikes down a mighty leader in broad daylight, and Alphonse falls prey to monsters in the dark.

A sinister voice rings out from the shell of Al's armor, and Ed and Greed find themselves under attack. As the Homunculi use the darkness to their advantage, a face from the past arrives to join the battle.

After investigating the twisted roots of the Bradley family tree, Mustang gathers his most loyal troops. Meanwhile, Ed and his allies continue fighting Selim, who shocks everyone by turning on his own kind.

With his father's help, Al takes incredible steps to contain the monstrous Pride. As the sun begins to rise on the Promised Day, the youngest Elric listens while the Homunculus ponders his very human mother.

Mustang leads a ragtag assault force of hardy northern troops - and welcome faces from the past - against Central's defenses. Victory seems certain until the military's most horrifying secret is revealed.
