Raised on the streets of a world where myth and reality intertwine, he discovered his unique ability to manipulate the fabric of space itself when wielding his broken half-sword, the "Voidblade". The other half of his sword is lost to time and legend, scattered across dimensions in a quest he's yet to undertake.
