In 2254 Theta Kalyb came under attack by the Chakuun, a race allied with the Tholians who conducted their bidding in the Tholian expansionist programs. A distress signal was sent and picked up by a nearby task force, in the region in expectation of Tholian attacks. The task force led by the USS Enterprise immediately diverted to render assistance but did not arrive before the colony had been reduced to ruins.
