Story
Perugius neither reigns nor rules — he wanders the sky aboard the flying fortress “Chaos Breaker,” yet at the court of Asura he is still honored. Rudeus seeks an audience with him (through an acquaintance begun by Nanahoshi) and gradually wins his favor, astonishing him with his dolls and his tale of the clash with Atofe.
When, in battle, Zanoba holds Atofe back and Rudeus's lightning magic immobilizes him, Perugius at last gains the chance to settle scores with his old enemy with impunity (without, formally, breaking the ban on “killing each other”). In gratitude he gives Rudeus a whistle for summoning aid, promises to teach him summoning magic, and supports his cause.
Perugius becomes an important ally: he is received in Asura during Ariel's struggle for the throne, and his servants, who can be resurrected, along with his mastery, are invaluable. Together with Nanahoshi he spends years perfecting a Teleportation magic circle; when her return home falls through, he swears by the title of Dragon King to bring the circle to perfection.
