Realmswarm

The Realmswarm is a loose confederation of planets; originating from multiple galaxies.

This loose confederation has no "capital city"; instead the confederation is made in a decentralized manner. When one civilization opted to join the Realmswarm, a "conference building" which links the civilization with the rest of the Realmswarm would be built. This conference building houses the Realmswarm Council, which is a decentralized, federated legislature connected by faster-than-light communications equipment which connected the individual buildings as if they are a single building.

They also enforce law by means of Peacekeeper Mechs.
