The daemonfey are a fiendish race of planetouched descended from the interbreeding of demons and sun elves in the Forgotten RealmsDungeons & Dragonscampaign setting. They are the elven equivalent to tieflings. True daemonfey are the scions of House Dlardrageth. Their bloodlines include those of demon princes. The fey'ri are those of the Siluvanedan Houses who allied with the Dlardrageths. They also possess demonic blood but not that of demon lords. The fey'ri are sometimes also referred to as daemonfey.
The daemonfey look like elves with demonic features, or particularly fey fiends. They are capable of magically altering their features somewhat, but in their natural form they have skin with fine scales, fiery red eyes, demonic pointed tails, and a pair of bat-like wings, in addition to their sun elven beauty.
