Tieflings are either born in the Lower Planes or have one or more fiendish ancestors who originated there. A tiefling (pronounced TEEF-ling) is linked by blood to a devil, a demon, a yugoloth, or some other Fiend. This connection to the Lower Planes is, for better or worse, the tiefling’s fiendish legacy, which comes with the promise of power yet has no effect on thetiefling’s moral outlook.
A tiefling chooses whether to embrace or lament their fiendish legacy. The three legaciesare as follows:   Abyssal. The heartless entropy of the Abyss, the howling chaos of Pandemonium, and the vast despair of Carceri call to tieflings who have the Abyssal fiendish legacy. Horns, fur, tusks, black blood, and peculiar odors are common physical features of such tieflings, most of whom have the blood of demons coursingthrough their veins.
Chthonic. Tieflings who have the Chthonic fiendish legacy not only feel the tug of Carceri but also the greed of Gehenna and the underworld gloom of Hades. Some of these tieflings look cadaverous. Others possess the unearthly beauty of an incubus or a succubus, or they have physical features in common with a night hag, a yugoloth, or some otherNeutral Evil fiendish ancestor.
Infernal. The Infernal fiendish legacy binds tieflings by blood not only to Gehenna but also the raging battlefields of Acheron and the diabolical Nine Hells. Horns, spines, tails, golden eyes, and a faint odor of sulfur or smoke are common physical features of such tieflings, most of whom trace their ancestry to devils.
