Dark Age

The Dark Age is the period that followed the Collapse when the Golden Age ended. According to Lakshmi-2, "a thousand kings" rose and fell during this age. It is followed by the City Age.

The Dark Age was a time of vast suffering and terrible evil. Many survivors formed colonies in the wilderness in a desperate attempt to survive. Colonies tended not to last long from either alien hordes or infighting. Humanity was on the fringe of extinction. But out of it, the Awoken emerged, and the Exo appeared from the ruins with their memories broken. Furthermore, the Ghosts had begun looking for their Guardians, and rumours circulated of the haven beneath the Traveler that would one day become the City.

The Cabal established a beachhead on Phobos for initiating the invasion of Mars. During the invasion the Cabal encountered the native Vex programing the Virgo Prohibition, and began a massive war of attrition following their nearly uncontested conquest of Mars. The Vex fought to protect the entrance to their "birthplace", the Black Garden, from the ever expanding Cabal Exclusion Zone. This war was fought with little outside interference, the City busy with her own problems.

Eventually, tentative Guardian reports of a Cabal commander, Bracus Tho’ourg, who secured the Buried City on Mars with merely a fraction of the planet’s current Cabal force, reached the ears of the Vanguard. The first Guardians who faced him died at some point between here and the City Age.
