Selûne's eternal foe is the evil goddess Shar, and she battles her ceaselessly on many planes of existence, both through mortal worshipers and servitor creatures. The undying enmity between the two goddesses predates the existence of most, if not all, of the present-day existing Faerûnian deities. The enmity between Shar and Selûne carries into their priesthoods, such that open battle often occurs when followers of each faith meet.<br/><br/>Shar has a secret order called the "Dark Justicars". In order to gain admittance to the order, a priest of Shar has to have killed a priest of Selûne.
