Reaper

"Reaper was born into a hardworking mining family in the Twin Souls clan. Four years ago, his only sister joined the Fist of the Twin Souls - the security forces charged with protecting the clan. After a dangerous skirmsh left her injured, Reaper left the mines and joined the Fist in order to watch for her safety. His agile handling of the drills translated to able marksmanship, and his keen intellect gave him a grasp on three dimensional combat tactics that many lack.

Reaper lost everything on Twin Souls, he will not rest until he witnesses the total annihilation of those responsible."
