The Citadel

Our Mass Effect Roleplay's version of the Citadel is an ancient deep-space station that serves as the political and financial capital of the Sol System. After the Crucible was detached from The Citadel it was found that most of those onboard, including the refugees from Omega and Batarian Space, were still alive. The Council was almost immediately overthrown after being scapegoated by Sol's citizens for the reaper's attack and lack of planning prior to it. C-Sec quickly stepped in to gain a semblance of order on the station, but most of it's inhabitants set towards solid ground save a handful of volus, turian, and asari. Those who remained devoted themselves towards returning the Citadel to a seat of economic and political power. The Council was reformed with each planet and race's new governments creating new seats in the Embassies. Extranet broadcasting also helped keep the Citadel pertinent, keeping the majority of journalistic broadcasting between Earth and the Citadel itself.
