Age of Darkness (jan 1, 5293 BC – jan 1, 4294 BC)
Description:
The Age of Darkness was a thousand-year period in which the sun's light was blocked by the ash knocked into the atmosphere by the meteoric impacts of Earthfall. It began with the impact of the Starstone in -5293 AR and lasted until the sun's light had been restored, roughly in -4294 AR. During the Age of Darkness, all major civilizations across Golarion were destroyed, ushering in a time of anarchy and destruction.https://pathfinderwiki.com/wiki/Age_of_Darkness
