@xfrode1 That's true, but only if we're talking about the chromatic white dragons. There are other species of white colored dragons, some of them are actually good.
But given her coloring, I thought of her as being a silver dragon and not a white one. Metalic dragons are usually good dragons, and silver dragons in special are one of the species of dragons that enjoyed the company of humans and elves so much, that they assumed human forms and lived among them. I'd imagine her being a somewhat arrogant, but good natured person.
Kind of like, well, those rich little girls that either speak with "wara wa" or a "desu".
