  For page 138:
  Circle Trigon (5109) is a neutral Class-F planet in the
  Romulan-Gorn-ISC Neutral Zone. Originally an Orion
  colony, it functions in a similar role to Mad Jack’s Hole, an
  open marketplace where all manner of stolen and other-
  wise discovered things can be found. It is a den of thieves,
  spies, and pirates run by a Klingon renegade who has
  amassed enough weapons to ensure only a major fleet
  can challenge his power over the planet.
