“Sprites are shy and reclusive faerie people, related to other faerie-folk, like brownies and leprechauns. There are several varieties, including pixies and nixies. Most have small, semitransparent wings, and elven features.
Normal sprites have distinctly elven features and live in meadows and wooded glens. The naturally invisible pixies are perhaps the most intelligent and mischievous of the faeries; they dwell in idyllic woodlands and delight in harassing travelers with their pranks. Nixies are water sprites that live in freshwater lakes, and, while they harbor no grudges against humankind, they delight in enslaving men as their beasts of burden. Other sylvan creatures related to sprites include the swift atomies and the mischievous grigs, both forest-dwellers.” Monstrous Manual, 2nd Edition
