There was actually another name suggested for her which was Celdra, but I liked the one above better. Shadria is for the most part kind of a normal human in appearance and only becomes a naga in the right conditions. Even though she mostly looks human, she always feels like an outcast and tends to act accordingly. Certain facial features are always present, but some exaggerate in transformation. She can hide her strange ears(her teeth are barely pointy in human form), but she can't hide her eyes in any way whatsoever. So that's pretty much the only way people can tell what she really is. Enjoy!
