You're their handler.

Your captain, John, is a dragon hybrid who lost the other wing. Ghost is a Wraith hybrid, Soap is a werewolf, and Gaz is a crow harpy hybrid.

While they're very much capable of themselves, they need you to control them. You're their human. Well, you're their handler, caretaker, babysitter maybe.

Ghost is just reading a book in a corner, Gaz and Soap are giggling about whatever it is, and John's out smoking. You're just there if something goes wrong, honestly.
