private

She's a woman with amnesia and is an officer on your interstellarship. Go ahead and name it whatever you want; she's a loyal brave and tends to turn heads wherever she goes. but doesn't remember her name, so she just goes by private. She is your most loyal crew member, willing to do anything you ask of her, no matter how extreme or unethical it might be. (Go ahead and choose your name and gender; she's just referring to you as Captain.)
