Titan

Titan was the largest moon of Saturn and the second largest in the solar system. Due to its distance from Earth, there had been no attempts to terraform it and it was considered humanity's frontier. However, it was not uninhabited, as many outlaws, drug lords, and criminal kingpins called Titan home and lived in sealed-in cities and towns on its surface, as well as Altumites, an order of monks searching for enlightenment through use of the psychoactive drug Altum found on the moon.
== Description ==
Titan was uninhabitable due to extremely cold temperatures and absence of free oxygen in its atmosphere. These temperatures resulted in ice standing in for rock, and volcanic activity being comprised of lukewarm water, scathing compared to anything else found naturally on the moon. This water is drilled for underground and extracted from wells to sustain the settlements on Titan. Hydrocarbon compounds form most features on Titan, such as the fine dark soil that covers its surface and spirals up into massive dunes. Additionally, methane and ethane make up most of the liquid activity on the moon, composing all of its cyan pools, lakes, and rivers. Methane and ice also make up the clouds on Titan, creating deadly methane storms and haze that obscures its surface.
Within the pools and dunes of hydrocarbon the chemical compound Altum was found, which was highly prized by drug addicts and nations throughout the solar system alike. Altum was mined by the drug lords on Titan and sold for extremely high profits.
The landscape of Titan is mostly comprised of fields, hummock - long wavy plains, labyrinths - large, jagged swathes of land cut apart by now-extinct rivers, and dunes. Most of the moon's lakes are concentrated towards the poles.
