The U.V. System or Frigido System is a star system that includes the planet U.V. 6 (thus presumably 1-5 similarly named worlds). Its feeble sun casts ultra-violet light which makes the planet U.V. 6 have an unnatural glow.
- The word Frigido probably comes from the spanish word frígido (adj.) when translated to english is frigid (adj.) meaning "very cold, stiff, Glacial".
