Bael Turath was a hedonistic empire in the south of Weldforn during the 1st Era. The Human nobles were only concerned with wealth and pleasure. During the War of Wills, the leaders made a pact with Devils to combat the creatures of the Far Realm. While they did manage to beat the aberrant creatures, their empire was forever shattered. Present day Tieflings are the descendants of the survivors of that empire, Bael Turath. Their bloodline is tainted by their diabolical connections, passing to their descendants through all generations.
