The Witch is not violent for the sake of being violent but has no problems causing hassle for the fairy government. She believes her side of the royal family suffered unfairly at the orders of that side of the family now dominated by Roxannadrell and Eileen and seeks revenge. Eileen has tried to talk the Witch out of this but with no joy. The Witch wants witches to be treated with more respect (not a bad thing) but is prepared to do anything to achieve it (definitely a bad thing).
I like contradictory characters. They're huge fun to write for and about too.
