Changes

The ''Red Planet'', as it is called, is acclaimed as a wonder of the galaxyGalaxy. In the early 22nd century Century it became the first planet to be terraformed by humans. After being made habitable, the planet was settled by industrial cartels, and it soon developed into the first [[Hive World]] and a centre of industry and scientific advancement. During the [[Dark Age of Technology]], the empires of Mars and Earth peacefully coexisted.{{Fn|2}}

During the [[Age of Strife]], Mars endured long centuries of isolation as complete anarchy ripped through [[Terra]].{{Fn|6a}} During the long time While Mars was cut off from Terra by chronic [[Warp storms]],{{Fn|7a}}, Marsthe planet's own atmospheric shields gave way, exposing it to deadly radiation that devastated the planetMars. During this time, fallout shelters represented the only hope for one's survival on Marsthe Red Planet. Technology, now responsible for one's very existence, soon became revered and the worship of the [[Omnissiah]] began in earnest.{{Fn|6a}} Any humans remaining outside the shelters devolved into cannibal mutants or were wiped out by insane automata and A.I. which stalked the surface.{{Fn|6b}}

Long before the Terran [[Unification Wars]], the survivors on Mars had developed their own culture, guided by the [[Cult Mechanicus]]. After battling against many horrors including the [[Cy-Carnivora]],{{Fn|17}}, they eventually reunited the planet, founding the Mechanicum. As time went on, Mars began to send expeditions to Earth to reclaim lost technology there, and even sent fleets into the void beyond the Sol System to found new Forge Worlds.{{Fn|6b}}
