When he was young Quinlan showed great promise in the Tamian martial art known as Tesque. He wasn't spectacular by any means, but the trainers saw potential in him and helped to mold him into one of the best Tesque practitioners in Sunsgrove.
Crim, however, with his heftier frame and altogether nasty disposition, was passed over for advancement many times. He grew to hate Quinlan, resorting to bullying tactics and altogether striving to make his life miserable.
When Quinlan tried to personally see to it that Crim was given a fair shake by their instructors, Crim was so enraged at the gesture that he nearly knocked Quinlan unconscious during a sparring match, refusing to let up his offense until their instructors physically separated the two.
Many years later, and finally matured, the two Tamian came to tolerate each other's presence as best they could. Crim is now fighting at the Tesque Master level, and considers himself to be the finest warrior in the Tamian Kingdom, and also thought he was a shoo-in for Captain of the Royal Guard when the position opened up.
However, history has a bizarre tendency to repeat itself, and Quinlan was hastily promoted to the position when his grandfather, the former captain, passed away suddenly. In response to the news, Crim vowed that he would publicly embarrass the new captain, proving to all the Tamian people that he was the best fit for the position.
Whether or not he succeeds in doing so is a story left to the pages of the comic!
