Tiefling

A tiefling is a creature in the Dungeons & Dragons fantasy role-playing game. Tieflings are "planetouched"; that is, they are mortal creatures that have in their blood some otherworldly characteristics. Tieflings are descended from demons, devils and other creatures of pure evil alignment; although their evil ancestor may be many generations removed, the taint still lingers. In the Planescape campaign settings, tieflings are a common race available to player characters, though they are mistrusted and reviled by almost all other creatures acriss the planes. The good-alignment-derived counterparts to tieflings are called aasimar.
