Geological / environmental event
The shroud that had for so long cut Klestan off from the rest of Atolvance lifted in 626 and began to move along the east coast.
The Primordial Haze finally moved away from Klestan and southeastern Atolvance in the Harvest month of 629. It began a slow spread along the eastern coast of Atolvance, shrouding them in mist for years to come.
