Any of several organizations that allows various terragen and alien clades representation.
The first Councils were established during the later Empires period. Currently there are two competing councils, in addition to a multitude of minor "official" ones. The ComEmp Council was originally a deal between the empires and some neutral worlds, in addition to being established as an interclade diplomacy council to lessen friction. This was naturally very popular among the xenodiplomats of the Eden Institute! However, there also appeared an independent council sponsored by some other group, and Eden (the system) got a certain amount of weight too. The different councils work differently, have overlapping memberships and often reach different conclusions.
