The Cave of Pearls.
The perfect place for all miss fits, mutants, and monsters alike.
Because no pearl is perfect.
But all are beautiful.
Nightshade knows this. She's spent her life looking out for those who have been cast out by society. Those rejected by friends and family. Those who were pushed, pushed to perfection, pushed so hard that they broke.
They all had the same story. "Once it got out that I was… different… well, things changed."
Then she met Fluttershy. Well, Flutterbat.
The newest pearl.
This should be interesting.
