Nein Auraa, director and first unit commander of the fairy-regulating agency Dorothea, once shaped battlefields as the "Witch of Ainedern" during the War of Unification. A veteran of the Seven Knights, her tactical brilliance and fairy Morzneak—a deer-like entity that freezes targets on contact—proved decisive against artificial fairy soldiers and rebels. Her wartime persona, marked by a strikingly feminine appearance, hardened post-conflict into the disciplined authority required to lead Dorothea, though flashes of warmth emerged, such as her wry humor with subordinates or sheltering the creature Chima.

Strategically secretive, Nein concealed Marlya Noel’s rare ability to summon a fairy without implantation while navigating alliances with Prime Minister Golbarn Helwise and Duke Schwarz Diese. Their collaboration fractured over political clashes, notably artificial fairy deployment, prompting Nein to quash Schwarz’s rebellion with her chainsword Aliadra—a weapon morphing between blade and whip.

Her influence extended beyond combat: rescuing Klara Kisenaria from wartime assault spurred Klara’s fairy organ transplantation and loyalty to Dorothea. Later, Nein overcame adversaries like Beevee Liscar, whose fairy Eizenkopf nearly bested her, by exploiting Morzneak’s freezing power despite injuries. Amid crises—Golbarn’s assassination, shifting political tides—she stabilized chaos through adaptive leadership.

Investigating Ministry of Fairies conspiracies with scholar-descendant Marco Bellwood, Nein pursued fragments of the Black Fairy Tome, aligning Dorothea’s missions with state interests despite betrayals. Her arc weaves tactical rigor with veiled compassion, forged by war and stewardship of a fractured postwar world, relentlessly confronting shadows of past conflicts to secure an uneasy peace.
