After officially becoming the new Duke Aegir, Ferdinand set about reforming his territory. Thanks to the wisdom of his wife, Dorothea, Ferdinand's policies were of massive benefit to the commonfolk and brought about a swift recovery. In recognition of this achievement, he was called upon by Emperor Edelgard to introduce these reforms to the Empire at large as the new prime minister. Though the work kept him very busy, he always managed to find time for Dorothea. It is said that their children filled their loving household with beautiful music ever after.
