Elizabet Karliene

Elizabet isn't a spiritualist because she wanted to be one. She became a force to be reckoned with out of spite. Cursed by a wraith like cultist as a child, Elizabet was taken in by the spiritualists for her own protection. Now the spiritualists watch over her as a young woman with simple hopes that she doesn't self-destruct. Collette became a spiritualist because she wanted to, but has since kept to the path out of necessity. Like Elizabet, she's cursed with something that gives her strength but just as effectively threatens her life.
Their similarities and talents that can provide one another great aid are obstructed by several minor yet seemingly insurmountable obstacles. For one, Elizabet can't stand the pretty and talented Collette and often lets her jealousy get in the way of acknowledging any benefit to being around her. For two, Collette greatly dislikes that someone as brash as Elizabet is just as well respected as she is and would rather dismiss her own talents than admit she shares any strong traits with the other woman.
While everyone else prepares for their only chance to fight the slippery cultist that cursed Elizabet and so many others, she's too busy arguing with Collette for the two of them to work together and potentially save a lot of lives. Including their own.
