There were many things Chrysalis was prepared to lose. Her hive, her children, and her crown were not amongst those things. Fleeing her old home, with no one to turn to and nowhere to feed, she stumbles across a town she didn't know existed.

From serendipity hatches an opportunity. From opportunity, progress. And perhaps, one day, even redemption. It is a long way off. There is a lot for her to confront, both in her past and future. But she has a lot of time in exile.
