Kayas tatoo

you remember the girl in my pic "New York gals"? (I think that's the name)
this is her tatoo, Kayas tatoo.
this tatoo is a dragoon tatoo, a tatoo that you're born with and that gives you controll over Dragons and possibillity to turn to one too.

I have to do a story to them, it's a competition....as you know...
and to win you need a good pic, a story and informations bout the characters.
