Tiefling

Tiefling is a Magic: the Gathering creature subtype introduced for the crossover Dungeons & Dragons: Adventures in the Forgotten Realms set.

Description
Tieflings are humanoid creatures with demonic/devilish features, as they have a Demon or a Devil as ancestor. They often have a reddish skin, horns, non-prehensile tails, and pointed teeth. Other, more unusual characteristics include a sulfurous odor, cloven feet, or a general aura of discomfort they leave on others.

Background
Tiefling originally is a Dungeons & Dragons type. The creature type has similarities with the earlier established Magic Azra race, but with the added tail.
