Luna

Phyne, also known as Josephine White and Luna, is a Lunarian with the power to manipulate the energy of the Moon. She was appointed by the Watchers to be the Guardian of the Sol System, and she operates within the system unless reporting to her superiors elsewhere in the Milky Way. One of her primary tasks as the Guardian is to ascertain that other beings devoting themselves to protecting areas of the Sol System are worthy of doing so, though she often struggles with whether she herself is worthy.
