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.
