What is "awilix"

Awilix (also spelt Auilix and Avilix) was a goddess (or possibly a god) of the Postclassic K'iche' Maya, who had a large kingdom in the highlands of Guatemala. She was the patron deity of the Nija'ib' noble lineage at the K'iche' capital Q'umarkaj, with a large temple in the city. Awilix was a Moon goddess and a goddess of night, although some studies refer to the deity as male. Awilix was probably derived from the Classic period lowland Maya moon goddess or from C'abawil Ix, the Moon goddess of the Chontal Maya.
