I haven't finished this drawing, but I hope to do so soon.
Here she is!

Description of mistwings

Description: dark purple, light purple, or light blue with yellow, orange, or green on their cheeks, beaks,  and wing membranes as well as their feather-like spikes that are on their head and spine.  Silver underbellies.
Abilities: though their spikes look harmless, there are hidden blades at the tip of them that contain a venom that can drain a full grown dragon's strength. Some mistwings can turn into mist for a few hours, but they normally end up ingured after.

They don't have any royalty. Mistwings hate being told what to do and tend to follow their own rules.
