Nope. Spent nineteen years thinking she was just a regular person, then she died and came back to life with wings and firebreathing.

[Her tone is wry; she fully expects this explanation to only raise more questions.]

She has feathers, though. Well, scales too. Sort of a combination of all the other dragon types, doesn't seem to fully be any one of them. Apparently when dragons are raised by other dragons, they learn their form from their parents, but she didn't have dragon parents, so....

[An eloquent shrug]

I guess her dragony magical bits sort of improvised.
