A cataclysmic event occurred in the northeast corner of the continent, permanently rendering that area a blasted wasteland, and altering the shape and culture of the continent. The Adlon Empire collapses literally overnight, and Rhyduania fractures into nation-states mostly along provincial lines. Natural disasters decimate populations, and the sudden absence of central government and trade regulation causes enormous and vicious conflicts for resources over the coming decades. As a result of the widespread destruction, nearly all history from before the Sundering is lost, and history from the first two centuries after the Sundering is foggy and poorly understood. Any attempts to sail past the northeast corner of the continent end in doom, with rare survivors claiming to have witnessed entire ships dropping beneath the waves like stones.
