Theta Cygni is a star system, a binary star visible from Earth in the constellation of Cygnus. There were at least twelve planets in the system, at least one of which had borne sapient life. (TOS episode: "Operation -- Annihilate!")

HistoryEdit

At some point between 2067 and 2165, blastoneuron neural parasites infected the population of twelfth planet Theta Cygni XII, causing the inhabitants to go extinct. (TOS episode: "Operation -- Annihilate!")

In 2165 a Tellarite freighter reported receiving a distress call from Theta Cygni XII. Starfleet dispatched the USS Essex to investigate. Captain Bryce Shumar reported to Admiral Jonathan Archer that the Essex had found all life on the planet had been destroyed by chemical and bacteriological warfare some time ago. Shumar informed Archer that as far as the Essex could determine the planet had suffered a wave of mass insanity, and that a number of ships had been launched prior to the destruction of all life on that world. Because Theta Cygni burned hot the crew did not have a reliable means of tracking where the ships had gone due to the interference generated by the star.
