Quartz

Quartz Fume is an Equestrian dragon and one of the new and youngest students of the School of Friendship. Enrolled by Princess Ember after she felt sorry for her being an outcast as a result of being one of the rare individual dragons to be unaggressive and love ponies, and her molting, which was one of the most intense and mature versions, has caused her to be ousted and live on her own, and since nobody wanted anything to do with her, she was signed up for Twilight's School, and fit in better than anyone expected. She's almost the same age as Spike The Dragon, and shows signs of having a crush on him.
