There seems to be a slight mix up between Gvaudoin and Fricorith. Fricorith has blond hair, but neither of his parents appear to have that hair color. Jennail has black hair, and Kvornan has brown hair. Gvaudoin doesn't appear to be noticeable, as she has black hair like her father Kiernan. However she doesn't bear any resemblance to her mother Nylissit. Instead she and her aunt Jennail both use a slightly modified version of a custom face already in CAS. So, Fricorith may have been meant to be Nylissit's son, while Gvaudoin may have been intended to be Jennail's daughter. But this may have just been a mistake by the developers.
