"I know who the hell I am."
Rolf was a friend to Kiora and a member of the Black Gulls, a small gang from Nox. He was a pushover with a big mouth who acted both mischievous and violent. He was known not to handle alcohol very well, amplifying his mouth and violent tendencies. In the gang he would act as the lookout and sniper during the jobs, but would have to fill-in Kiora’s role of roughing up any enemies when she refused to go along.
In the present adventure, none of the other heroes know of any such person or of Kiora’s past at all [perhaps with the exception of White but that has not been made official].
[Also yes I totally used paint to change the color of hair and eyes—the original image is of Sothe from Fire Emblem =P]
