Antoinette
Imagine a sphinx, buts she tells you the answer to the riddle before letting you even think abut it. She does love to make riddles but also loves to show off her brilliant answer, this makes her a terrible gatekeeper and has been fired from every job she gets, and who would hire a sphinx as anyone but a gatekeeper- she's extremely broke how does she afford to get her hair done?
Life would be so much simpler if she was a star in a distant galaxy, she dreams about this often and has a star tattoo on her left shoulder, upper back and right flank.
