Nocty Finds a Core Crystal

Nocty finding a shiny core crystal in a chest, thinking they'll bond with it- only to find it bonded in a completely different way. The core rewriting their entire being into a small and surprisingly powerful (and with a beak!) Finch. Though they don't really remember being anything else. They can't really seem to remember much at all.

what was this again?

Note, I added a beak as I thought that was a woeful missing feature of her design.
