Ayre is a disembodied Rubiconian who interacts with Augmented Human C4-621 through the Coral in their body. Following their unexpected "Contact" during the Coral War, she provides 621 mission support complementary to their broker Handler Walter's. Whereas Walter refers to 621 by their designation as an Augmented Human, Ayre refers to 621 by their borrowed callsign "Raven."
