Thetis

Thetis is a character that I'm working on for a story idea.
She is a green dragon that lives deep in the forest a few miles away from a village. Because dragons are very territorial, she never allows any humans into her forest.
In human form, she has olive skin, brown hair, and green eyes. Her personality is very suspicious and distrusting at first, but then she becomes loyal and loving. She can be very stubborn.
In dragon form, she is barely bigger than a human. She has a 15ft wingspan and can breath fire. She lives in a cave set into the cliff side of a mountain.
