Carol was the daughter of General Kovaks and a powerful wizard who was trained in the temple of Boon's Tooth. During the second breaking she met the half demon Barak and aided him and Grog the Mighty in defending Grogonia from the Swiftish forces who had assaulted the castle.
Later she had a bunch of crazy adventures with Barak, then married him and had a kid. After that Boon cut her power off and she jumped off a castle tower to her death. A lot of awesome stuff happened in between meeting Barak and her death though, I'll talk about it later.
