Pretty much my own How To Train Your Dragon species and character. Honestly the wings should have been larger yet, but eh.
Its a very swift flier, even in the harshest blizzards. It has a natural resistance to extreme cold, but can't tolerate heat as well, unlike most dragons. Each pattern on these dragon varies greatly per individual. The ice breath they contain can manifest in a few ways. Sometimes it may be a light, breezy frost. Other times a direct ray of hail. Or a blast of freezing rain.
