Tiefling are individuals cursed by a bloodline of an infernal source. Shapeshifting demons, cultists and other worshipers of devils and demons allow such blood into their family, running for generations eventually creating Tieflings. While most feel uncomfortable in the presence of a Tiefling, they are not naturally predisposed to act evil. Depending on their infernal heritage, they can have a variety of appearances. Asmodean Tieflings are the most common, with horns and tails. Vrockian Tieflings tend to have misplaced hooked noses, feathers, purple skin or claw like, black fingernails. Balor often stink of sulfur, have red or leathery skin and eyes like smoldering coals.
