Inshai Compact.
Historians' name for an interstellar government that was in power some 5000 years ago, a federation of approximately 36 hominid and non-hominid cultures. The Compact fell when a world of the Orion Congeries allegedly placed a sunkiller bomb into Sigma 1014 Orionis, homestar of Inshai. ("Spock's World" [Pocket TOS HC #1]).
