Thanatos

Thanatos is one of the moons that few people from the surrounding moons barely even speak about. Thanatos was one of the first moons where colonization was attempted, but the efforts of the colonists failed (although an atmosphere was established) and many died as the colony quickly ran out of food and water before help could return.

Nowadays the moon is home only to criminals, but very few of them at that. Even the depraved and deranged feel fearful of this place. The entire moon is empty of unnatural structures except for the one colonialist town with mostly rotten buildings and remnants of dead colonialists occasionally still visible where they had not been buried by whoever was insane enough to return.

Geography
Thanatos has a mountainous and rocky terrain with several lakes of liquid water, the moon has a notable inhospitable look to it. There are several resources of precious metals, but none extracted as of yet. There are no large forests and little vegetation, just enough to maintain a weak atmosphere. Some plants spread after being planted by the original colonialists, but only in small pocketed areas and they seem very much isolated.

Climate
Because of Thanatos' odd placement near Olympus, it receives below average sunlight and thus a colder climate, agriculture is difficult yet not impossible with help from artificial light. Extreme storms are possible and can be deadly, but are rare.

The terraformed atmosphere makes Thanatos livable by blocking radiation and providing breathable air, but the bleak weather means that there really are no seasons and the moon is generally cold year around.
