History: Selesdria is the first-born daughter of Queen Moon and King River and the older sister of Star. Since she was born she demonstrated to have magic but it was uncontrollable and unpredictable, and in addition, she had delicate health, since she suffered from high fevers from very young. Doctors, the High Commission and her parents feared that she would not survive childhood, so Moon and River decided to have another daughter, whom they later called Star.
Selesdria's health barely improved over the years and her magic was still uncontrollable, also, she did not demonstrate the same energy and strength as Star, so it was decided that Star would become the queen and not Selesdria. Although she doesn't hold a grudge against Star and her parents because for it, Selesdria distanced herself a lot from her family and became lonely, preferring to read a book or being alone rather than be surrounded by people.
