Our main baddy of the story. As the queen of Naviar, she searches for more power in order to control all four kingdoms. When she was Queen Alexandra, she took notice of the rumors of the mystical powers of Katherine and Maryann, and wished to take them for her own needs. After the sisters' execution, she was able to fake her own death, and took on another name; Marina. As she used her own magic to make herself a different, yet youthful appearance, she was able to convince the nobility that she was Alexandra's "Sister". Now as Queen Marina, she continues to search for the powers of the sisters, as they are heavily connected with powers of the spirit world. The question now stands; Why? Why does she wish for complete control of Alvoreon? And will she succeed?
For reference, try to think of someone who can hold a strong grip on people. Although, I might just cast two people for this role, one person as Marina (who has a higher pitch than her other counterpart) and Alexandra. This does not mean that they are two different people, as both of whom is cast will have to say some lines together.
