Juliena Veltrine

Backstory
Juliena had a great childhood, although she hated Liriina very much. When Juliena was 15, her house caught on fire, and Juliena saw Liriina escape without even trying to help her parents. This angered her, and she slowly tracked Liriina down, and spied on them so she could ruin Liriina's life.

Silencing Maria
When Maria was three, Juliena kidnapped her and attached a device that silenced her physically and magically. Then she was released, and when Liriina discovered it, it distressed her greatly.
