she is bipolar, which means she does have weird mood swings, but on to her backstory, she lived in a treehouse, and she heard a roar, she looked outside to see a wyvern, it grabbed her with its talons and ripped her arm off, and clawed her eye, she had enough and ripped its wing off, it roared and ran off. she now has a wing as an arm :D oh and she was a lab experiment so she has no parents or siblings
