An Empire of Ethian humans consisting of conglomerated city-states ruled by brilliant sorcerer kings, dating from the time around the establishment of the Ward. The influence of this empire stretched across Telara, fueled by the power of Sourcestone.
Unfortunately, their technology fell into the clutches of insidious dragon cultists. After the events of the Convocation, the vast majority of the Eth Empire was reduced to a barren wasteland (the Droughtlands), and the empire itself collapsed soon thereafter.
