I have been instructed to lead this world. I will bring peace. Why do you bar my path?
— Idunn, to Roy.

Idunn (Japanese: イドゥン Idenn) is the primary antagonist and final boss of Fire Emblem: The Binding Blade. At one time, she was a Divine Dragon like Fae, before being turned into a Demon Dragon and having her soul destroyed by the warring dragon clans during The Scouring.

Fire Emblem: The Binding Blade


Though dragons were formidable opponents during the Scouring, mankind had strength in both numbers and, compared to dragons, the ability to reproduce efficiently. Eventually the war began to go in favor of humanity, the warring dragon tribes appealed to the Divine Dragons, asking them for one of their own to become a Demon Dragon, which could produce artificial War Dragons to increase their dragons' numbers and turn the tide of war.[3] The Divine Dragons, however, regarded the idea of War Dragons to be an abomination against nature and refused.[4] The Divine Dragons then vanished from history. The Divine Dragons are implied to have escaped to Arcadia, of which there are still some residing there by the time of The Binding Blade, such as Fae,[5] and Fire Emblem: The Blazing Blade depicts various dragon tribes, an Ice Dragon in particular, living in the village.[6]

Idunn, however, stayed behind because she feared the Divine Dragons would eventually get into conflict with the other dragons.[7] She was captured by the warring dragon tribes and turned into a Demon Dragon, but she still refused to create the War Dragons. Because of her refusal, the dragons destroyed her soul in order to make her follow their commands.[8] The War Dragons were born, and the war began to shift in favor of the dragons. However, when defeat was looming over humanity, they combined their greatest technology and magic to forge the Legendary Weapons, designed to battle dragons. The weapons were given to the Eight Legends, who used their power to fight Idunn's War Dragons. Mankind also used the calamity of Ending Winter, caused by the great power of the dragons and Legendary Weapons, to its benefit, leading to Idunn's defeat at the hands of Hartmut the Champion. The remaining dragons were either killed or banished to another universe lying beyond a magical portal located on Valor Isle.

Instead of killing Idunn, however, Hartmut took pity on her and sealed her away with the Binding Blade. She remained bound for nearly a thousand years until King Zephiel of Bern released the seal. Having lost his faith in humanity due to years of abuse and an assassination attempt by his father, King Desmond, Zephiel wished to crush the world of humans and give it to the dragons, who he believed should have won the Scouring. Jahn, one of the last, if not the last, members of the Fire Dragon clan remaining in Elibe, approached Zephiel after Idunn's release and assisted him in realizing his goal.

Under Zephiel's and Jahn's command, Bern moved to conquer the entirety of Elibe, but was stopped by the combined forces of Lycia and Etruria led by General Roy of Pherae. After Roy's defeat of Zephiel, if the player collected all the Legendary Weapons and the Binding Blade is intact, Roy will track down Jahn and Idunn. After Jahn is defeated, Roy faces Idunn, who has continued to follow her dead master's order to produce War Dragons to conquer the world. If the player defeats Idunn using the Binding Blade and Fae is still alive, the true ending will occur and Idunn will be spared by Roy (if not, Idunn will be killed by the falling rubble in the collapsing temple). She is brought to Arcadia, where the Divine Dragons restore her soul, though they are unsure as to whether she will ever return to normal, having been separated from it for so long. In the last scene of the Epilogue, Idunn is seen laughing with Fae, giving hope that she would eventually return to her previous self.

Personality and character

During the events of Fire Emblem: The Binding Blade Idunn is shown to have minimally functioning emotions, and follows Zephiel's orders with no objection. This is due to her soul being damaged by the other dragons that wished to use her power during the war with the humans, the Scouring.[9]

Before this, Idunn was a Divine Dragon, like the other Divine Dragons Idunn did not wish to participate in the war.[10] Idunn faltered in her resolve to vanish, she did not want the Divine Dragons and the other dragon tribes to turn against each other.[11] Idunn was unsure of causing the dragon tribes to conflict with each other, but she would also not serve the warring dragons, she refused to obey them, she seemingly did not wish to war with the humans.[12]

  3. "We were eventually overwhelmed by the sheer number of you humans. It was then we decided to form a demon dragon capable of creating war dragons. [...] Correct. The divine dragons, however, were opposed to the idea. They said it was an affront to the laws of nature." — Jahn, Fire Emblem: The Binding Blade
  4. "As we tried to persuade the divine dragons, they suddenly disappeared without a trace." — Jahn, Fire Emblem: The Binding Blade

  7. "It hesitated, however, as the rift between its tribe and the rest of us widened." — Jahn, Fire Emblem: The Binding Blade
  8. "Idunn was immature, but of enough strength to fulfill our purpose. Its heart, however, wasn't with us. It would not follow our commands." — Jahn, Fire Emblem: The Binding Blade
  9. "Agree? Ha. No. We destroyed its very soul to extinguish its will. It is a mindless drone intended to heed our every word." — Jahn, Fire Emblem: The Binding Blade
  10. "Correct. The divine dragons, however, were opposed to the idea. They said it was an affront to the laws of nature. As we tried to persuade the divine dragons, they suddenly disappeared without a trace." — Jahn, Fire Emblem: The Binding Blade
  11. "Precisely. The divine dragon Idunn was to become the demon dragon. It hesitated, however, as the rift between its tribe and the rest of us widened. Hesitation... Such folly is reserved for you humans. It serves no end." — Jahn, Fire Emblem: The Binding Blade
