Bregan D'aerthe was founded by the houseless rogue Jarlaxle, choosing to separate from the matriarchal drow society. He recruited mostly rogue drow males from the destroyed houses of Menzoberranzan and Ched Nasad. The organization began as a mercenary band widely employed by the ruling houses of Menzoberranzan, especially by House Baenre, which had the resources to hire the group regularly, particularly given that Jarlaxle himself was a Baenre. Arathis Hune was Jaraxle's first Lieuntenant, recruited in the earliest days of the organization.
