Imp

Imps are lesser devils found in the Nine Hells and in the Elemental Plane of Fire, but occasionally residing peaceably among mortals on Exandria.

Description
Imps differ somewhat in appearance—some are dark, ashen-grey with yellow eyes, others red—but they are generally described as looking like tiny, leathery-skinned, winged humanoids with barbed tails and sharp teeth. They are capable of turning invisible, and their tails have potent poison stingers. Some have been seen wearing armor.

 * When Vox Machina investigated the home of Sir Gregory Fince, they found him slain in the basement, and encountered an imp in the upstairs library.
