Dumas bears a cross-like mark on his left palm, an inherited symbol of servitude that has run in his family for generations. He is obsessed with changing this 'destiny', and sought to do so by becoming the Shard Champion. To his chagrin, all that came with the title of Shard Champion was "useless honor" and being the first person to call when trouble came about, with no change in his station or position. Obsession turned to madness, and he became Zymot's usurpers' spy, the Joker, in exchange for marriage to Princess Rebecca.
