Queen Nehelenia was once a queen of her own kingdom that was absorbed by vanity. In fear of losing her beauty, she consumed the dreams of her subjects to stay young. She sought the Golden Crystal in the possession of a priest named Helios (Pegasus's true form) and was sealed within a mirror by Queen Serenity as a result. Queen Nehelenia formed the Dead Moon Circus and used Zirconia as a proxy to track Pegasus down. Although she obtains the Golden Crystal, she is betrayed by the Amazoness Quartet who gives the crystal to Chibiusa. Using the crystal, Queen Nehelenia is defeated and begins to wither with age, forcing her back into the mirror she was once sealed within. Helios returns to his home realm of Elysion.
