A humanoid species was native to the planet Nukolee. They were governed by a monarchy.
History[]
In 2265, the people of Nukolee became afflicted with random bouts of temporary madness caused by gases deposited into the planet's atmosphere by Sanduy's Comet.
In 2267, the USS Enterprise transported Prince Raviki to assume rule over his people. After several inexplicable attempts on his life, they discovered the source of the madness and found an antidote. (TOS comic: "A World Gone Mad")
