Callista Winters has lived with the Guardians for so long that none of them can remember a time without her. Found abandoned as a toddler on a forgotten moon with nothing but a strange celestial marking glowing on her wrist, she was taken in by the Guardians and raised aboard the Milano. Nobody knows which god abandoned her, only that her powers are far too powerful for an ordinary child. Callie can teleport herself—and sometimes others—across short distances in flashes of silver-blue light, making her invaluable during missions despite her age.
