A small pseudo-planet hovering far above the Marshroom Kingdom skies. It sits in a pocket of space, surrounded by a spherical break in Space Magic that makes ordinary travel to it impossible.

The entirety of the planet is powered by a massive core of Life Force, Neutral Energy, Light Magic, and Dark Magic sitting at the center. This core sends plumes of its energy cocktail to the surface on a regular basis to create new Star Ghosts and grant power to the Star Wand, as well as replenish the light that fills the sky. The core's light is enough to live by, but the Omega Star sits in a permanent dusk with little to no variation year-round. Errant flares of the core's energy can also cause something resembling volcanic activity in isolated areas around the world.

As the Omega Star is entirely populated by Star Ghosts who live in harmony with each other, little variation is needed in architecture and amenities. They have no need for sustenance of any kind, either, so most valuable space is put towards residence and entertainment.
