During the Age of Frost and Flame, the civilisations of the ancients began to crumble and wage cataclysmic wars while the discovery of planar travel allowed extraplanar entities to enter the Material Plane. For the next millennia, the Material Plane was wracked by incursions of Devils, Demons, Elementals, and Aberrations. It was a time of chaos, war, destruction, and suffering, and the world lost many wonders to Frost and Flame.

During the Age of Frost and Flame, Devil Lords held dominion over the continent of Asdar for millennia, divided into their domains. The Age of Frost and Flame was a time of terror and destruction for the peoples of Asdar. In time, the Fae would return to the Mortal World to make war on the Devil Lords.
