The Zalkonians are a reclusive race native to the planet of Zalkon. In the 24th century, many individuals of the race were transforming into non-corporeal beings. The government dealt with these individuals harshly. Zalkonian warships are relatively advanced, and pose a risk to a Galaxy-class Federation vessel. The warships also possess some sort weapon which is able to suffocate crews of enemy vessels. First Contact with the United Federation of Planets occurred in 2366. The Zalkonians seem to occupy a region of space of unknown size. The Federation has apparently not been aware of the Zalkonians or their space as of 2366.
