The Interstellar Concordium ( or ISC ) were one of the primary antagonists in " " . They originated as a playable race in the " Star Fleet Battles " tabletop combat game by Amarillo Design Bureau . The Interstellar Concordium , or " ISC " , is a significantly powerful spacefaring political organization from beyond Gorn and Romulan space . The ISC emphasize the preeminent importance of order over chaos , and in the 2280s - 2290s their presence was requested by the Organian s to bring peace to the galaxy , thus beginning the Concordium ' s " War of Pacification " . The Organians , who had engineered the formation of a neutral zone between the United Federation of Planets and the Klingon Empire , had become disillusioned with what they saw as the deterioration of peaceful political relations among the major Alpha and Beta Quadrant powers following their return from the Andromeda Galaxy . The Organians requested the ISC to assume this political role through military subjugation in an attempt to teach the major galactic powers ( including the ISC ) how to unite against a common foe .
