A Twilight Zone World or Ribbon World is tidally locked to a star with a temperate band at the Twilight Zone, plus a Hot region (hemisphere) facing the Primary and a Cold region (hemisphere) away from the Primary.
- It can be classified on a Main World or non-MW trade classification.
- It is a Planet or world type.
Description (Specifications)
Ribbon worlds are tidally locked planets, aligned with a star, with one very hot side and one very cold side. Because of this, the habitable zones of these planets forms a thin ribbon around the equator.

History & Background (Dossier)
An example map of a twilight zone world.
- One side of the world permanently faces towards the star.
- One side of the world permanently faces away from the star.
- Between the two is a twilight zone, where the star eternally hangs on the horizon.
The star's gravity pulls the world into an ovoid shape, with the pointy side permanently facing towards the star and the more rounded side permanently facing away.
- Except in extreme cases, this effect is not usually discernable with the naked eye.
Worlds & Sectors (Astrography)
