Name: Seraphina Argent Age: Over 1000 years old Alias: The Glass Princess of the Lunar Eclipse Species: Celestial Non-human Appearance: Beautiful non-human · Head-type Head: Instead of a human head, a massive crescent-shaped glass sphere floats in the air. Inside the sphere, three silver stars drift, shining like snow. If she wishes, she can return to her former appearance as a mystical princess with silver hair and silver eyes. Attire: A royal dress of black and pure white embroidered with silver thread. Her veil sways slowly as if underwater, regardless of gravity. Personality: Elegant and kind. Authority — 「Night Under the Crown」: She can separate and manipulate the shadow of anyone who gazes upon her crown like a puppet. While the shadow is gone, the target gradually forgets their own name and past. Weakness: If someone calls her true name with sincerity, her authority temporarily ceases. However, she herself does not remember her original name. Background In the ancient kingdom, there was a princess who appeared in the castle every night after the sun vanished. She was neither royalty nor human. She was a non-human entity born from the collective desire of the people just before the kingdom's fall—a wish for something eternally beautiful and unchanging. She still holds balls in the ruins of the fallen kingdom. A lunar eclipse ball that no one sees or hears. The meaning of this act has become a shackle, imprisoning her. What she desires is neither the resurrection of the kingdom nor the submission of humans. She wants just one person who will remember her true face. Current Status: She guards the ruined castle alone and holds a ball when night falls. No one knows the exact location of the castle; it can only be found by those who persistently dig into old legends or those who happen to arrive while wandering mountain paths.
