Gloamings are planetouched creatures native to the Underdark who can trace their heritage back to creatures from the Plane of Shadow, though they are often mistaken for tieflings. Rare even in their home territory, almost all Gloamings are wanderers, with no central civilization or cultures of their own. They resemble pale-skinned halflings with catlike eyes and furry wings, and have the ability to cause their skin to emit a radiant torchlike glow.
