Saturn is a gas giant and the sixth planet from the Sun as well as the second largest planet in the Solar System.
Some time after the 2100's, Saturn's largest moon, Titan, was harvested in a large-scale planet-cracking process in the means of harnessing the moon's resources for humanity's use. Since then, a large space station called the Titan Station nicknamed the Sprawl was built around the moon. As centuries passed on, the moon became smaller and smaller with only a piece of rock left of it. The moon eventually became a large mine and inside it, a top-secret EarthGov research facility was built to study the Markers, and specifically an massive variant.
