Leith(Amonn)

Leith and her twin brother were created by a scientist while he was trying to recreate his dead daughter. As they weren't like her he sent them to be children for a royal couple, like the other failed experiments. She hated her twin brother as he tried to kill her since he never wanted a sister and disliked her adoptive parents as she considers her real family the scientist who created her. The scientist eventually realized his mistake and let her stay with him as his daughter. The scientist made her a new sibling and the twin was sent off to be killed as he was causing trouble.
