Elaith Craulnober is a fictional character in the Forgotten Realms fantasy campaign setting for the Dungeons & Dragons fantasy role-playing game. 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.
