History

Around 2446, Saturn's largest moon, Titan, was harvested in the very first large-scale Planet Cracking process with the goal of harnessing the moon's resources for humanity's use. Afterwards, a large space station called Titan Station was built around the moon.^[1][2]

As decades passed, the moon became smaller as it was mined further and further, with only a piece of rock left of it. The moon eventually became a large mine and, by 2511, a top-secret EarthGov research facility had been built inside it to study the Markers.
