Tragedy, sorrow, and loss define Golarion’s history. Infrequent cataclysms undo cultural and technological advancements, periodically forcing human society into a state of relative barbarism and flux. Earthfall, the catastrophe that brought about the end of mighty Azlant—the most advanced human society yet to dwell on Golarion—marks humanity’s greatest resetting. A thousand years of darkness, fear, and savagery followed Earthfall, during which time the magical, technological, and cultural successes of Azlant and Thassilon were lost.
