What Goes Around Comes Around

What happens if humans violate the natural order of power and tried to exploit those that are much larger and powerful than they are. Note that this is a dark GT story with destruction and loss of life. Only proceed if this is your thing.

Inspired by Neopuc's story "Captivity" over at FurAffinity. If you liked this one feel free to checkout Neopuc's too.

Spent too much time trying to build out the world in the first half of the story, but I promise it gets better in the latter half. Also, glad to complete the story right at the finish line of Macro March, with my propensity to procrastinate.
As usual, constructive critiques welcomed.
