Great Vanishing

The Great Vanishing is a major event that occurred between approximately 1800 BCE and 800 BCE, and primarily impacted eastern Aurora. The event itself, although not widely understood or investigated, marked a shift in the cultures of eastern Aurora in the form of a great tragedy or disaster that brought about the downfall of the major civilizations of the Chalcolithic Period. Theories abound as to what may have caused the Great Vanishing, from a devastating war to a great drought, or a combination of various events and natural occurrences.

Theories

Drought Theory

The drought theory primarily attests to the shift in climate that often occurs within the Great Auroran desert as a result of the shifts in the temperature oscillations that occur in the Pacific Ocean. It is believed a series of uniquely extreme climatic shifts occurred in succession of each other during the 21st Century to the 19th Century BCE, forcing the cultures of the time to resort to reverting their habits back to one of a hunter-gatherer society. This is partially backed by the oral stories taught in the Melit'hasa cultures of the central desert, mentioning a period where "generations abandoned their great towers of stone, as the water had run dry."

Great War Theory

The Great War theory attests that a significant civilization-destroying war befell the civilizations of the Chalcolithic Era, forcing them back into the Stone Age technologically. Many murals on ruins found buried under the Great Auroran Desert often depict battles not accounted for in our modern understanding of history, and as such historians and archaeologists alike place these murals as possible evidence of a devastating war. Stories passed down by the Melit'hasa also mention a major war that their people suffered.
