A trans-female Western sergal. Unlike her more vain twin sister Aphrodite, Gaea is more self-conscious and shy, but loves nature, loves comforting others, is very resilient, and is protective of her daughter Selene. This has allowed her to become quite a pushover. She has also often fallen ill for no apparent reasons. She is the fraternal twin sister of Aphrodite, as well as being the mother, yet biological father of Selene, and the former husband of the late Theia. She used to go by "Protos".
