Binding the many disparate empires and civilizations in a more direct manner than the links provided by trade or memetic confluence are various treaties and agreements. From mutual defense to sentient rights the life of the Civilized Galaxy is largely based on mutual interests laid out and codified.
Central Alliance - Text by M. Alan Kazlev Alliance of Sephirotic, Panvirt, Diamond, and Objectivist empires originally formed in response to the Hyperutilization Supremacy (see "Meeting at Googlehertz").
Jekaumeatrine Accords - Text by Stephen Inniss An agreement reached between the Efficiency Maximization Paradigm and opposing Sephirotic forces under the Paradigm Containment Organization, limiting further enforced 'optimization' of existing populations.
Tragadi Accords - Text by Todd Drashner Series of protocols and regulations outlining the expected behaviours and interactions among sentients from the various civilizations when they encounter each other in deep space.
