The effects of having a supernatural being such as a demon in your heritage last many generations. Planetouched is a general word used to describe those who can trace their bloodline back to an outsider, usually a fiend or a celestial.

Fey'ris are tieflings descended from elves and demons.

Fey'ris vary widely in their appearance, though in general form they resemble gold elves -tall, noble elves with bronze skin, hair of copper, black, or golden blond. All fey'ris have additional features reflecting their fiendish heritage - fine scales covering their bodies, huge bat-like wings, fiery red eyes, and long, pointed tails.

Fey'ris speak Common, Elven, and Abyssal.

Fey'ri Characters

A fairy's favored class is sorcerer.

In the Realms

The fey'ris are descended from three lesser noble houses of the gold elves, part of the High Forest kingdom of Siluvanede. Thousands of years ago, these elves fell under the sway of House Dlardrageth - a family of half-fiend elves exiled from the eastern elven lands of Arcorar. When Siluvanede was defeated by the moon elves of Sharrven and Eaerlann (their neighbors in the High Forest), members of these houses bred with demons in an attempt to strengthen their bloodlines. Centuries later, in -2770 DR, the fey'ris first unleashed their magical power in revenge, sending monstrous hordes against the elves of Sharrven, destroying their realm.

In the Year of Unfettered Secrets (880 DR), the fey'ris precipitated the fall of Ascalhorn two years later by helping a few wizards summon demons to oppose the devils that virtually ruled the fortress. In the resulting chaos, the elves of Eaerlann discovered the fey'ris and imprisoned them in several citadels hidden in the northern High Forest that House Dlardrageth had established millennia before. After the destruction of Hellgate Keep in the Year of the Gauntlet (1369 DR), the fey'ris were released. They joined in an alliance with the remaining half-fiends of House Dlardrageth, and from there have spread to threaten the North.
