Tezwa is a planet near the Federation-Klingon Neutral Zone. Its populace, the Tezwans, are ruled by a Prime Minister and an Assembly located in the city of Keelee-Kee. The gravity on Tezwa was 0.8 G. During the Dominion War, the United Federation of Planets installed weapons on the planet to use as a potential trap if the Dominion ever invaded; in exchange, the Federation gave material aid to Kinchawn, Prime Minister at the time. Presidential Chief of Staff Koll Azernal oversaw and Minister of Military Intelligence Nelino Quafina provided the resources for these nadion-pulse cannons and their controlling firebases, which were constructed in violation of the Khitomer Accords and seen as a last resort. Because of this, the cannons were kept offline and unarmed.
