Maulvais Garcon
Owner of the Castle Causuel, known as the Maulvais Garcon (“Bad Boy”) as a child.
He ran a crooked tournament out of his castle, in which a parrot was the prize. The lord of the most beautiful lady at the tournament was supposed to win. The Merciless Lion always presented an ugly woman, but he used force to win anyway.
He robbed and imprisoned many knights, before Arthur, fighting on behalf of the Lady Without Pride, cut off his arm and defeated him. At Arthur’s command, he freed his prisoners and made restitution to his victims.
