Frey, a former Ten Great Demon Lord, rules the Harpy Kingdom of Fulbrosia, her authority cemented by defeating her mother in ritual combat—a victory that exiled her sterile twin sister Nazim, deemed unfit for leadership. This formative clash honed her pragmatic, calculating approach to governance and power. Avian traits define her appearance: feathered wings, razor-sharp talons, and a humanoid guise she can adopt to mask her true form. White hair cascades around a crimson gem embedded in her forehead, while a red leotard and gilded adornments accentuate her regal presence. In battle, she dominates the skies, leveraging blinding speed and a unique skill to nullify opponents’ abilities by immobilizing them with her talons. A shrewd strategist, Frey orchestrated the Orc Lord scheme alongside Clayman to expand her reach, only to later ally with Milim Nava and dismantle his machinations during Walpurgis. Acknowledging her limitations against ancient demon lords, she abandoned her title to serve as Milim’s advisor, channeling her cunning into stabilizing the dragon princess’s realm. Her power surged after absorbing a beast army’s souls and defeating Nazim, ascending her to Awakened Demon Lord status. This metamorphosis transformed her into a Sky Spirit Bird, a celestial entity amplifying her aerial sovereignty and earning her the moniker “Sky Queen.” Relationships reveal her complexity: a patient, almost maternal dynamic with the capricious Milim contrasts with her rivalry-turned-respect for Karion, forged in joint campaigns against the Eastern Empire. She birthed three daughters—Claire, Luchia, Nemu—asexually, their lineage fatherless by harpy tradition. Beyond conquest, Frey’s intrigue with Tempest’s architectural innovations redirected her ambitions toward collaborative city-building, symbolizing her evolution from expansionist ruler to pragmatic unifier. Her arc weaves adaptability, strategic humility, and a shift from personal ambition to collective stewardship in a world shaped by primordial forces.
