Skull & Shackles
A tiefling is a humanoid who has fiendish or devil blood in their ancestry. Their appearance is usually affected by this, with many tieflings having horns, hooves, tails, wings or red skin. The appearance of an individual tiefling can vary drastically depending on their infernal ancestor and their human ethnicity. Most tieflings are feared and mistrusted because of their obvious heritage, even in Cheliax which worships demons. Because of their blood, most tieflings tend to be evil, but there are exceptions.
