This is part of the "shackled" world series.

A pit beast who gave up, she lost the will to keep fighting. She watched too many beasts die, she herself took enough lives. When she saw a chance to get away she took it, running for three days straight till her legs gave out during a thunderstorm. Now she lays in your backyard, drenched in rain as she stairs at she sky, if she died right here she would die happy, looking up at the clouds in the night sky.

However you have other plans.
