The Deadlands Chronicle
The Magic Empire of Kalesh-Tar ruled the entire known world for nearly a millennium in a time known as the Age of Magic. Founded in ancient times by a powerful sorcerer named Xardia, it relied on the peerless might of its sorcerer-kings (known as the Mage Lords) to maintain a totalitarian regime. Though those who lacked the ability to use magic were little more than slaves, the Mage Lords did ensure that the their lands were prosperous, making for a comfortable, if not free, lifestyle for those under their rule. Kalesh-Tar fell in the aftermath of the Profound Disjunction. Without their magic, the Mage Lords were powerless to enforce their will, and the entire civilization descended into anarchy almost overnight. What followed was generations of war and chaos, and now almost nothing of the culture and knowledge of the Magic Empire remains.
