Thanks for the review Kev! Glad you liked the ending.
For another twist to the ending...it really wasn't meant to end the way it did I just needed a finished product for the Siamang deadline. Someday I'll flesh it out then you'll see that maybe mine is also SF. It could be nanobots that keep healing everyone, could be that the prison is actually a matrix like digital version of the world, could be there are cameras throughout the prison and those that are incarcerated are merely entertainment for the alien nobility (those plague masks the magistrates wear are part of an enviro suit to allow them to breath the air on the surface of the planet). Who knows? I certainly don't, but I'll find out someday.
Heh, yeah, I kinda figured, but still entertaining. I had the same issue, and had to kill a lot of people very quickly before my story went over 15k.
