A bitter Groundskeeper of MapleClan, Bitternburn was the runt of his litter, coddled and kept safe--but this only made him angry. Wanting to be a Gladiator, he only grew more irritated when he was apprenticed to the Groundskeeper Rivuletfrost. Still restless in his position, Bitternburn has come to be more content with the help of his mentor, though still holds the bite and sting that his name suggests towards most of his clanmates.
