Machinima

Uninhabited
An artificial ice world, Machinima orbits two also artificial suns; one is a firey gas giant, the other, a giant ball of plasma. The gravity is constantly fluctuating, and in some places giant chunks of dirt and ice actually float above the ground. Ruins are scattered on the surface of the planet, and tunnels stretching deep underground indicate that the solar system was built by an extremely advanced alien race.
