Eskar

Has both a dragon form and a human form. scar is on left eye.

her father made her wear  iron bracelets when she was young (still deciding why) and did not  approve of her hanging around the other dragonets in the village,  especially Draconiss. He intended to move and take her with him, but she  rebelled and he scratched her. His claws had toxins on them (he worked  with potions) and so the scratch never healed. Eskar remained with  Draconiss in the village for many years (and they ended out together)  but they left one day to try and find jobs in the magic council after  Draconiss figured out how to shapeshift into humans (although they still  have dragon features) At some point they met a young centaur who had  the ambition to create a school in which magicals and hybrids were  taught together. Eskar and Draconiss helped her (which is why they are  teachers at triplestar academy)

They ended out hearing about  raven though some dragon contacts, and while working out the school,  they brought her up as a human, teaching her about the world (so this is  why she understands english and dragon, and why she knows most of the  functions of modern things.) And they let her into the school as one of  the 'test students' on her first year.
