Plitvice is a goddess of war.
She controls fire at will. She isn't at her full power as the tree of life was burnt down 500 years ago. But she is still a formidable warrior that can make any foe tremble. She appears authoritative. In fact, she's obsessed with looking that way. Perhaps, it's an over compensation for being a young goddess who is actually quite sloppy. She was sealed away in Heavenhold, waiting for the arrival of a worthy champion.
In her long life, she lost many loved ones. She even lost contact with her faithful servant, Angie, while she was sealed away. Making new friends is exciting but also terrifying to her. After all, it is highly probably that she'll outlive most of them.
