Taking place three years after Ed and Al entered the real world. The War is almost over and Germany is on the verge of defeat. Its brave Fuhrer Hitler cannot save it from the enemies they have made. All of the world is against them. Ed and Al are stuck in a small town of Germany with nowhere to go. Shreds of their Alchemical powers still linger in their bodies but as days pass they feel it fading slowly but surely.Ed now works in a Explosive producing factory where his knowledge of explosives is paying him big bundles of money and Alphonse is surprisingly still unemployed.
Back in the alchemy world, Colonel Roy Mustang has risen to the rank of Fuhrer and is now known as Fuhrer Roy 'Hawkeyed' Mustang. The nickname comes from the fact that he is engaged with Leftenant Hawkeye. Major Armstrong has taken over as the Military Ambassador in Leor and is developing the city 'in his image'(By 'in his image' i mean LITERALLY in his image).
Winry competed in the Automail mechanics Award event and is now working for a huge automail engineering company in Central City. Unfortunately her grandmother died a year back. She has been laid to rest beside the house and Winry visits her once every month.And speaking of death, Hughes' grave is filled with flowers and is visited by his wife and daughter who is now 7 years old. Winry sometimes visits him as well. And some reports confirm that at night a figure is seen to pay his respects in secrecy to Hughes and according to the witnesses the figure looks similar to Fuhrer Roy Mustang although no confirmation has been found.
Everything is going as they should, when one day Fuhrer Mustang got a report stating that the sealed gate to the real world is showing signs of reactivation.
At the same time, a new type of explosive was being developed in Germany as a desperate means of winning the war. This new type of bomb had immense destructive power and some speculate that it might even destroy the entire planet. But all these fell into deaf ears as the war climbed its climax. Germany had finished developing the most powerful bomb the world had ever seen. Coincidentally, it was Edward's factory which got the order to mass produce this explosive.
Fuhrer Mustang sent out a group of state alchemists to investigate the phenomena. And sent a message to a very unlikely ally. The leader of New Ishbal. Oh i almost forgot to mention that the Ishbalites have been given freedom and the right to call them a country once again as soon as Roy Mustang was appointed Fuhrer. This new leader was a very shrewd and demanding leader who wanted to make Ishbal the most powerful nation in the alchemical world but strangely he was good friends with Roy Mustang.
The message was a request to study their ancient method of alchemy. Roy Mustang was trying to find a way to completely destroy the gate between the two worlds.
After a day of hard work, Ed returned home to his loving wife, and his brother. I forgot to mention that Ed has married as well. And if you guessed that it was the gypsy girl, you were right. He did marry her. Al still has feelings for Winry and longs to see her again although he knows its not possible anymore.
Unknown to the two brothers, the laws of equivalency has demanded that their time of peace come to an end and thus the two worlds are heading for a collision course that will reunite them with their old friends and some old nemesis.
