City Age

The City Age was an era that began after the Dark Age when the Last City was founded. Survivors of the Collapse began to appear, traveling to the sanctuary which the dormant Traveler protected, and the City started to grow. Looking through various sources on the beginning of the Dark Age, which directly succeeded the Golden Age, as well as comments made by the Guardian's Ghost throughout most of the campaign missions, it can be assumed that the Dark Age and the ages that followed would have lasted for at least four centuries.
