Mamunes are small creatures said to prevent folk from finding their way home after a night out at the inn. They are said to gather on the eve of Saovine. They are mentioned, along with misguids, by the villagers of Upper Posada in the short story "The Edge of the World".

These little creatures are seen throughout The Witcher, but they serve no obvious purpose. They tend to gravitate to Geralt and dance around him but otherwise do not interact.
Geralts mentions that the closest mamunes are in Vizima when he and Regis were in need of their glands for their hallucinogenic properties to brew Resonance. Regis also mention mamunes later, after the meeting with Syanna and the dutchess, when commenting how Toussaint's appearance can deceive.
