Titan

Titan is the largest moon of Saturn. It is known for its dense atmosphere, seas of liquid hydrocarbons, cryovolcanoes, and bizzare ecology. Unlike other planets and moons which life was introduced to, Titan's overall atmospheric composition and temperature have been altered very little. Life was originally created on Titan using a combination of genetic modification and dEvo, in a quest to provide Titan's colonists with an ecology and source of food. Titan's life inhales H2 in place of O2, metabolizes it with acetylene instead of glucose, and exhales methane instead of carbon dioxide, unlike Earth's life. While Titan's oceanic fauna is biodiverse, it is lacking in flora, except the small darkly colored lichens and mosses which convert methane into H2. A large portion of the moon's surface is a desert.

Humans have had a presence on Titan since the 22nd century, leading to the foundation of Titan's capital, Huygenston, named after the discoverer of Titan.

While Titan's gravity is much less than Earth's, gravity suits allow anyone who wishes to easily switch between Earth's gravity and Titan's, as to prevent bone loss.
