 Excluding these last two, the various powers were loosely aligned (except during the alliances solidified during the General War) into two opposing camps headed by the two superpowers, the Federation and the Klingons.The Romulans were Klingon allies, and the Kzintis and Gorns were Federation allies (the Gorns being particular Romulan opponents because they share a common border).The Tholians separated the Klingons and Romulans at the galactic rim, and thus posed an obstacle to their cooperation.
