Unofficially, the most notable star cluster in the Terminus Systems, taking its name as it does from the Omega space station, unofficial capital of the Terminus. Most worlds here are in Omega's shadow, but there is a great variety of interests represented here, including worlds under the jurisdiction of the former Batarian Hegemony and its successor, the Batarian Confederation, volus and elcor colonies, and krogan clan rule.

Post Reaper War, the Omega Nebula connects via relay to the Zahel Sea, Sigurd's Cradle, Nemean Abyss, Pangaea Expanse, and Tangeal Expanse.
