Overview
Mars has become a Forge World in the Imperium of Man, producing vast amounts of weapons and other technology for the Imperial war efforts throughout the galaxy.

Mars is also the twin planet of Holy Terra, and one of many-long inhabited worlds near the Cradle of Humanity. It is the home and power center of the Adeptus Mechanicus, the ancient and Byzantine priesthood of the Machine God, and the heart of their galaxy-spanning monopoly on human science and technology. Therefore, Mars is just as important to the Imperium's survival as Holy Terra. Mars is peppered with towering hive cities, and there is very little of the planet's surface which remains untouched by the constructions of the Mechanicus tech-priests. Mars had a terraformed atmosphere and living ecosystems during the Dark Age of Technology, but the constant warfare of the Age of Strife destroyed the world's manufactured oxygen-nitrogen atmosphere and restored the Red Planet's surface to its primordial state, absent surface water and breathable oxygen. The only inhabitbale regions of the planet are now the Adeptus Mechanicus' hive cities.

Mars is ruled over by the Mechanicus' Fabricator General, and he possesses almost every known piece of STC technology or designs. This is ostensibly so he can construct better and more durable vehicles and technology, although it is fairly clear that he is simply hoarding them.

Its also rumored that the presumably most powerful of the C'tan, the Void Dragon, sleeps somewhere on Mars, in the Noctis Labyrinthus, perhaps the reason why Necron ships briefly landed there in 997.M41. [[Category:M]]
