The USS Enterprise orbits Pyris VII in 2267
|Location:||Alpha or Beta Quadrant, Pyris system|
Prior to 2267, the Federation conducted several surveys of the planet and discovered that there were no signs of life located there. In 2267, Korob and Sylvia established themselves on the planet for the purpose of learning about the Federation. When the USS Enterprise visited the planet, Korob and Sylvia engineered the capture of several crewmembers and used a variety of "magical" tricks on them such as voodoo, to keep the Enterprise crew on the planet.
However, Sylvia quickly became infuriated with the sensations of taking humanoid form, and became dangerously irrational. In order to defeat the aliens and escape the planet, Captain James T. Kirk destroyed their transmuter, and the aliens quickly perished. (TOS episode: "Catspaw")
- The planet was incorrectly referred to as Pyriss VII in the novel.
