The frigid northern borderlands become a battlefield when Kimblee finally closes in on Scar. Deeper into the frozen wasteland, Ed and Al's fight is against the bitter elements as they struggle to reach Fort Briggs.

The soldiers at Fort Briggs remain ever vigilant against the threat of spies from Drachma. The massive compound may seem impenetrable - but a violent intruder offers destructive proof to the contrary.

Ed uncovers a conspiracy of staggering scope: a plot that has already claimed countless victims. Clues suggest that Fort Briggs will soon know bloodshed - and an entire nation will suffer.

As Raven tries to corrupt Armstrong, Ed and Al can only wait in their cell. Long ago, their father faced his own captivity, confined to an eternity of regret in an undying body. To escape the pain, he said goodbye.

Hawkeye is shocked when the first Homunculus reveals itself. Far away, Edward is surprised by an offer from Kimblee: Fullmetal can have all he has searched for - in exchange for becoming a mass murderer.

When Scar is cornered by a pair of gruesome chimeras, the Elrics enter the fray as his unlikely allies. Later, Winry's attempt to confront Scar over his role in her parent's death ends in disaster.

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.

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.

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.

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.

As Envy writhes within the firestorm unleashed by Mustang's vengeful rage, Hawkeye must take drastic measures to prevent the Flame Alchemist's hatred from burning out of control.

A rebel victory is imminent and hope takes hold among Mustang and Armstrong's troops. Central's forces teeter on the brink of collapse - until their fallen leader returns to take control.

Central's forces fight with renewed vigor following Bradley's return, and the Fuhrer himself enters the battle. His first opponent is an armored tank. His second foe is even tougher.

The battle for a nation's soul descends into chaos. Bradley unleashes death on those who dare engage him. Beneath Central, the one responsible for the Fuhrer's creation unleashes something far, far worse.

Mustang must make a difficult choice: will he break alchemy's greatest taboo? Or will he watch the person dearest to him die? Meanwhile, it grows ever more difficult to discern where Ling ends and Greed begins.
