Theta Cygni XII was the formerly inhabited twelfth planet in its star system.

Between 2067 and 2265, this planet was invaded by neural parasites that came from Levinius V. The civilization on Theta Cyngi XII was destroyed in the mass insanity caused by the parasites. The inhabitants transported this parasite over to Ingraham B. (TOS: "Operation -- Annihilate!")
