Elaith Craulnober is a fictional character set in the Forgotten Realms fantasy setting. Elaith is often used by author Elaine Cunningham and has appeared in many of her novels, namely, Elfshadow, Elfsong, Silver Shadows, Dream Spheres, and briefly as a very young child in Evermeet: Island of Elves. He is often portrayed as a cunning and opportunistic elven rogue with an infamous reputation, although the Forgotten Realms campaign setting presents him as a fighter/wizard. The author uses him both as an antihero and a recurring villain, and is often referred as "the Serpent." Elaith has also made an appearance in Neverwinter Nights as a merchant who has taken up a calmer outlook on life.
