To pay for Merle's medical care, Arlen, heir to the legendary Fist Sage, was forced into the bloodstained arenas of the Valor Sect as an underground boxer.

Now, armed with the skills honed in the pits and a heart burning for vengeance, Arlen sets out on a relentless quest: to find Merle and make those behind the slaughter of his family pay in blood!
