Citadel Council
The Citadel Council is an executive committee in Mass Effect with considerable political power that operates from the Citadel. It is composed of one representative each from the Salarian Union, Turian Hierarchy, the Asari Republics, and the human Systems Alliance. It is headquartered at the Citadel space station. The volus, elcor, and hanar have official embassies on the Citadel. The krogan had an embassy before the Krogan Rebellions, the quarians had an embassy before losing their homeworld and colonies to the geth, and the Batarian Hegemony had an embassy, but they withdrew because they were offended by the Council's attitude toward the practice of slavery.
History
The Citadel Council was founded shortly after the salarians and the asari made first contact. The turians were invited to join the Council after playing an instrumental role in ending the Krogan Rebellions. In 2183 the humans joined the council after defending the Citadel from the Reaper Sovereign and a geth fleet.
Authority
The decision-making power of the Council is limited. It has command of a defensive fleet that protects the station and of Citadel Security (C-Sec), and the Council can appoint SPECTREs at its own discretion. Beyond these immediate powers, the Council members must usually consult their homeworld governments before making any major decisions.
