“One thousand years... My strength has long recovered. I can feel it...”
Jahn (ヤアン Yān) is an antagonist from Fire Emblem: The Binding Blade. He fought in The Scouring and survived the war, nursing his wounds in the Dragon Temple when Zephiel undid the temple seal. When Jahn approached him, Zephiel, now the King of Bern, expressed the desire to return the land of Elibe to dragons.
Jahn is the last boss before Idunn, the Demon Dragon, who can be fought if certain conditions are met. As the player fights to reach him in the temple, he tells Roy his story and what happened in the Scouring.
As the Scouring went on, the Dragons started to lose the war due to their inability to reproduce fast enough to keep up with human numbers. Due to this, the Dragons approached the Divine Dragons (who had remained neutral) to ask for one of their own to became a Demon Dragon who were able to produce artificial soldiers known as War Dragons.
The Divine Dragons refused and disappeared, though one stayed behind. This dragon, Idunn, was captured by the Dragons and was forcibly transformed into a Demon Dragon. In order to control her, her soul was shattered so that she would obey the Dragon's orders. Idunn would come to be viewed as a symbol of hope by the Dragons.
Though the dragons alone were blamed for the elemental imbalances in the world after the Scouring, Jahn reveals the Ending Winter was caused by the clashing of the tremendous power of the Divine Weapons. This forced Dragons to seal their powers in stones in order to survive.
The humans took full advantage of this weakness to ruthlessly crush the Dragons in their weak humanoid forms. During the storm of Dragon's Temple, Jahn battled one of the Eight Generals and was heavily wounded by a Divine Weapon, then left for dead.
Jahn would survive with a permanent scar and remained in the temple to recover from his heavy wounds. Due to the Scouring, Jahn would become the last Dragon not of the Divine Tribe to remain in Elibe.
Jahn, here referred to as "enigmatic man", also appears in the ending of Fire Emblem: The Blazing Blade, as a man in a red cloak who is talking to Zephiel, asking why he had awakened Idunn. He later recalls this conversation when telling his tale to Roy in The Binding Blade, noting that he did not trust Zephiel at the time, but worked with him because Zephiel was Idunn's master.
Jahn is a cunning individual, but also brutally honest, revealing the dubious tactics used by both human, and Dragon. Jahn is unemotional by the standards of humans and says that Dragons do not feel emotions in the same way as humanity.
Despite denying hatred towards humanity, Jahn seems devoted to the idea that dragons and humans cannot live together and that one race must be driven out of Elibe for the other to survive. When Roy mentions the existence of Arcadia, a place where the Dragons and Humans live together in harmony, he shrugs it off, calling such a place absurd.
“So, I have lost... Humans are truly unpredictable...”
—Jahn's death quote in The Binding Blade.
Jahn's battle theme is called The Last Dragon, which plays when he is fought in battle.
- According to a Japanese gaming news website, Jahn landed 51st place out of 80 in the character popularity poll for Fire Emblem: The Binding Blade.
