Second Chance: God Killer

A 71-year-old man is living out the tag end of a rotten life in poverty. Glarney Fered is a systems analyst and a black belt in the self defense art of Loro. He's a very good systems analyst and can defeat men half his age in hand combat. However neither skill is of much use to a 71-year-old man.
However, Glarney is hired as a bodyguard for a religious figure. They search the West coast city of Alvero, just two old men seeking a mysterious scroll. As the search goes on, Glarney thinks and fights his way through a gritty, inner-city environment. As they close in on the location of the mysterious scroll, Glarney comes to realize that his client will kill Glarney once the scroll has been obtained and Glarney is no longer needed. Since his client knows where Glarney lives, Glarney can't run and has no choice but to lead the religious figure to the scroll. Glarney and his client unsuccessfully try to steal the scroll from the temple where it is hidden. Glarney tries to escape but is caught and has to then kill his client in a fight of legend. Glarney not only kills his client in self defense, in the process, Glarney eats the client’s life force.
Glarney then thinks to just live out his life in a little bit of comfort. However, Glarney finds himself growing a bit younger. He then has to again fight for his life against bandits and again becomes a bit younger. Glarney realizes that he can continue to grow younger if he can just obtain more life force.
Glarney then begins an epic journey to try to obtain more life force. The next stop is a southern city, where Glarney becomes involved with drug smugglers. The drug smuggler turn out to be aliens and Glarney is captured by alien police. However, the aliens need Glarney to track down one of the escaped drug smugglers. However, Glarney realizes that he's to be killed when he does track down the alien drug smuggler.
However, Glarney is clever and he won't just give up his second chance!
