Cerul is a female deity, or goddess, and is the first wife of Glaux, according to the Azathrin, and Glauxian Azathrel. Although the existence of Cerul, and a wife of Glaux entirely was not present in the Glau'ra, multiple pseudo-canonical sections of it and chapters of the Azathrin mention goddess wives and servants to Azath, the god of the Azathrel faith.
