The Goddess of the Moon and the leader of the (now dead) 400 southern stars. Coyolxauhqui was crippled by Huitzilopoctli and has been trapped in the sky ever since.
The Moon Goddess was once the Lord General of the vanguard of Coatlicue, the Primordial Mother, but when it was prophesied that during the last Nemontemi she would give birth to the New Sun, so she attempted to kill the Mother of the Gods, but before she could she commit her coup the bastard was born whole and in full battle regalia.
He slaughtered her brothers and sister, and spread the survivors across the sky, before tearing her apart and shattering her power. Now, trapped in the night sky, Coyolxauhqui is as bound by fate as any of the Teotl, but she waits for the stars to align and the Tzolk’in to open and for her father, the Primordial Star, to return her to her full power.
Coyolxauhqui died when her brother, Huitzilopochtli, leapt from their mother’s womb and killed all his siblings when they, under her command, led them to murder Coatlicue before he could be born. She died, along with her brothers and sisters, and Huitzilopochtli threw her head up into the sky where it became the moon (so that their mother, Coatlicue, would be comforted by always seeing her in the sky) then her body down the hill of Coatepec.
