The Arthonean Cleansing
Commonly referred to as "The Day the Sky Fell", The Arthonean Cleansing was a worldwide apocalyptic meteor shower event that directly or indirectly killed the majority of life on Arthos. It is estimated that Arthos suffered 18 major impacts to its surface and a countless number of minor impacts that remain unknown due to crater erosion.
Prehistory
Virtually no records of culture dating before the cleansing survive. Very little could be done in the way of preservation as the immediate aftereffects of the meteors did not spare those weighed down by personal belongings. Many artifacts, those fashioned from stone, were able to survive the elements but were soon found and destroyed during The Age of Revival. Historians believe this was the result of an iconoclastic movement to destroy the sins of the past and ensure the gods would not allow a cleansing to occur in the future. Both historians and religious institutions now regard this as a mistake.
