inaugural media installment. The Citadel Council is introduced in Revelation and is presented as the governing body and ultimate authority in Citadel space: the councilors pass judgement for violations of Council law, settle disputes between interstellar governments, and occasionally provide direct intervention in the form of special operations by delegating to its special forces personnel, the Spectres, which count asari commandoes among their number. A representative from the asari is always a member of the Council along with the salarians and the turians. In the video games, asari characters are encountered either as non-player characters or enemy units in innumerable missions and scenarios. Several asari character variants are playable in the multiplayer modes of Mass Effect 3 and Mass Effect: Andromeda. Asari characters are featured prominently in several Mass Effect media including novels, comics and an animated film, either as main or supporting characters. Asari characters are first encountered in Mass Effect following the departure of the SSV Normandy from the human colony Eden Prime. Councilor Tevos features as the asari representative of the Citadel Council during the game's events, and depending on Shepard's actions, can be killed during the final battle. Matriarch Benezia, a notable leader among her people, is initially sighted as an aide of the rogue turian Spectre Saren Arterius on board the Reaper Sovereign; she is later encountered in the planet Noveria as a boss, supported by a squad of asari commandoes. One of her subordinates, Shiala, is encountered on the planet Feros where she had been absorbed by the Thorian, an ancient sentient plant-like creature capable of mind control abilities and creating clone copies of Shiala to use as its avatars; her once-blue skin had turned a shade of green as a lasting result of being integrated into the Thorian's physiology. Benezia's daughter, Liara T'Soni, is located on the world of Therum by Commander Shepard, where she joins the crew of the SSV Normandy afterwards as a party member and plays a pivotal role in discovering the location of Ilos, a lost Prothean world which contains an artifact sought by Saren. Mass Effect 2 introduces Illium, a colony world operated by asari corporate interests which serves as an entrepôt between the Terminus Systems and the Asari Republics, as one of its primary settings. Numerous asari characters appear either as allies or enemies. Two notable asari who first appear in Mass Effect 2 include Aria T'Loak,
