Origin: main planet
The last Queen of a dying cosmos, she held he first Queen Examination of her cosmos, and transported Candidates Angelique Limoges and Rosalia to a planet in a new cosmos (Shinchou) to compete to become its queen. She then transported all the planets and inhabitants of the dying cosmos to Shinchou and entrusted them to the new Queen, Limoges.
Back when she was a candidate herself, she was summoned to the Sanctuary, but there was no Queen Examination, the Guardians chose her over fellow candidate, and future attendant, Dia. She accepted the position of Queen, breaking Clavis' heart, who had fallen in love with her.
