Cegilune

She was a member of the Unseelie Court, the general of the Queen of Air and Darkness and 'mother' to the Hags. She spied on the enemies of her queen through the use of a sickly illusory moon that hung high over the sky during the long period of darkness in the Feywild. Even before her position as general she was reviled by the fey, however. Cegilune was a fey being who had sold out her fellows and allied with the fomorians, tutoring a young Karontor and becoming the consort of Grolantor (and possibly the mother of the Hill Giants). Her Nighthags had, at one point, invaded the realm of Mellifleur in Pluton, before her queen required her for the ritual of the Long Night, which she performed with the help of the entire Unseelie Court (she would later return to this realm).
Now after the long battle against the madness of the Seven, she is one of the last deities that exists in order to confront it in the last battle
