The History and Mythos
The world of Imperian, the continent of Aetherius, suffered a massive cataclysmic change when the moon of Imperian split, wreaking geographical havoc across the surface of the land. New mountain ranges appeared; seas engulfed the land; deserts expanded and cities faded into memory.
After thousands of years the people of Aetherius reforged the world in their new diverse image. Races created safe harbors for their own, massive walled cities were created for defense, magic twisted old lands into supernatural new areas.
