This is a redraw of an older picture I made. The character is from a dream I had in which I was trying to keep her away from foals cause her powers were unstable. I failed and she ended up killing a lot of ponies because she was scared while hiding from them in the bathroom.
 
The name that came to me when thinking of her was permanent Rarity. I’m sure its not the mlp Rarity but she is somehow related to the mare. Her design was originally more draconoques-like but shifted to dragon-like as I drew her. Her color scheme was supposed to be like that of nightmare Rarity but I changed it to this cause I thought it suited her better. Her magic is very unstable due to her horn being broken. She can still use magic but she can’t focus it too long and her aim is practically non-existent.
