The Prince of Undeath
Hundreds of years ago, the leaders of the human empire of Bael Turath made pacts with devils to solidify their hold over its enormous territory. Those humans became the first tieflings, and they governed their empire in the name of their infernal masters. In time, Bael Turath came into conflict with Arkhosia, the ancient empire of the dragonborn, and decades of
warfare left both empires in ruins. Bael Turath’s grandcapital was thrown down in ruin.
