Heirs to an ancient, infernal bloodline, tieflings have no realms of their own but instead live within human kingdoms and cities. They are descended from human nobles who bargained with dark powers, and long ago their empire subjugated half the world. But the empire was cast down into ruin, and tieflings were left to make their own way in a world that often fears and resents them.
Tieflings’ appearance testifies to their infernal bloodline. They have large horns; thick, nonprehensile tails that range in length from 4 to 5 feet; sharply pointed teeth; and eyes that are solid orbs of black, red, white, silver, or gold. Their skin color covers the whole human range and also extends to reds, from a ruddy tan to a brick red. Their hair, cascading down from behind their horns, is as likely to be dark blue, red, or purple as more common human colors.
