Formed after the fragmentation of the Covenant, the Kig-Yar Privateer Alliance is a major organisation encompassing thirteen star systems and dozens of planets, planetoids and asteroid colonies. A loose collection of pirates, privateers and mercanaries, the Privateer Alliance managed to establish itself as a significant presence during the War of Vengeance, and while its allegiance was constantly shifting depending on who could provide it with better incentive to fight for their cause, they were eventually annihilated by the Sangheili Armed Forces in retaliation after rogue Privateer Alliance ships attacked the relatively minor colony world of Triumphant Virtue.
