Xek Rychtevorik's 3991

Forcibly conscripted as a child under a tyrannical regime, Exékiel reaches his breaking point and goes AWOL.
In the year 3991, Exékiel is soon plunged into a new life as a free man, and must now find his place in a world that is nearly two thousand years post-nuclear war and recovering.
After being taken under the wing of an ex-sky pirate and his wife, operators of a bounty hunting ring, Exékiel goes back to doing what he was trained to do his entire life. Killing and tracking down targets is second nature. Only this time, it's on his own terms.
