Union of Cygnus-Orion

The Union of Cygnus-Orion, colloquially the Union or the UCO is an intergovernmental organisation which includes all of the galactic nations in the known galaxy. It was created as a successor to the Local Cooperation Agency in the aftermath of the Great Galactic war. The UCO was a project largely pushed by the Terran Federation as a means to mend its diplomatic image following the conflict. 
The organisation has succeeded in preventing further large-scale galactic conflict. However it is considered by many, especially aliens, to be a tool of domination of the great powers. The Committee has wide executive and judicial powers in the matters of individual states. Much criticism has also been directed at the Terran hegemony within the organisation. The Federation has used the UCO to pass legislation which allowed its corporations to expand to foreign markets and for large scale immigration across the galaxy. Nevertheless the UCO has succeeded in improving relations between galactic nations, most notably between the Ur-Han and Terran Federation with other countries.
Every nation in the galaxy is represented in the UCO. There are three members, which are the great powers of the galaxy: the Mirdesh Confederacy, the Terran Federation and the Surben Republic. The other members are the Tesrat Republic, Menya Union, Ur-Han, the Terran dominions and the Mirdesh consituencies which are all represented separately from the the Confederacy itself. ALEPH is the only non-state member of the UCO, but is considered a "special corporate observer". 
The Surben Republic is the current president of the Committee.
