A Sound Of Thunder
Every tiefling descends from aristocracy. When the humans of Bael Turath damned themselves with devils’ bargains, only the heads of the noble houses bound their families to hell. The common people retained their humanity. No one in Bael Turath who bore horns and a tail did not in some way relate to those who signed the original pacts. Most tieflings alive today cannot accurately trace their ancestry to any particular house. Generations of tieflings partnering with each other and with humans have blurred the bloodlines of the noble houses, making it nearly impossible to trace the dark path of inherited guilt. However, some tieflings actively seek the truth of their past, and a few among them find it. Others simply find it comforting or useful to claim descent from a noble house, regardless of the truth of their birthright.
