Jahn

Yahn (also translated Jahn) is a an antagonist from Fire Emblem:Fūin no Tsurugi. He fought in the Scouring and had been nursing his wounds in a temple when Zephiel undid the seal on the temple. When Yahn approached him, the King of Bern expressed the desire to return the land of Elibe to dragons.

Yahn is the last boss before Idoun, the Dark 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. During the Scouring, dragons were blamed for the elemental imbalances in the world. In truth, it was actually the tremendous power of Divine Weapons wielded by the Eight Heroes which had caused it. He also explains Idoun's stories.

Yahn also appears in the ending of Fire Emblem: Rekka no Ken as a man in a red cloak who is talking to Zephiel.
