Mages of the Suel Imperium and Baklunish clerics called down the Rain of Colorless Fire causing the Twin Cataclysm in the regions of the Dry Steppes and the Sea of Dust west of the Flanaess. A confederation of Barbarians, the Oeridians, flee the devastation of unbridled magical power by heading east over the Crystalmist mountains and invading the Flanaess. The Sulouise survivors soon follow in the thousands. Together these two peoples fight amongst themselves and the native populations, the Flan, for control. Baklunish survivors head north past the Yatil Mountains where there culture continues to this day.
