Mars

Mars is the fourth planet from the Sun and the setting of Dark Colony. Once a desert planet, it has been transformed by humans into a mostly habitable planet using vast factories pumping oxygen into the atmosphere. Scattered across its surface are colony bases, set up by human terraformers for easy colonization.

The Jungle
The jungles of Mars are prime examples of terra-forming done correctly. Lush vegetation and a high oxygen level make for a comfortable haven for humans. Ample shade is provided by dense foliage and water flows freely into lakes and streams.

Desert
High levels of Delirium in the soil have created barren areas, with naked rocky terrain, scorching high temperatures, and very thin air. These desert areas are suited more for the Taar, who do not require as much oxygen as humans and are more tolerant of the heat. The only cover is provided by the webs of the Flynt, an indigenous arachnid species that managed to survive the planetary overhaul.

Ruins
Rumors about previous civilizations on Mars have been prevalent on Earth since the discovery of canals in the early 1900's. It wasn't until routine Martian probes returned pictures of architectural ruins, especially the haunting images of the Cydonian Head, that these rumors were accepted as fact. What lies behind these ruins is still unknown
