Sometime later in the story, (to be written, by me and my sister; working together) is when Nyx herself, finally learns to heal her own broken, crystal-like wings, and restore them back to normal. (And, after a change of heart. No spoilers from there, though.)
I figured that a lot of you, would find this to be a nice idea. So, I drew it out!
