Theril is an Amadician that the Shaido took as gai'shain. Although under sixteen years of age, and therefore too young, he was lanky and tall for his age and the Shaido did not believe that he was only 16. Along with his father Alvon, he tried to run away three times before swearing fealty to Faile. He and his father have coarse accents that make them difficult for others to understand. When Galina asks Faile to steal the binding rod for her, it is Theril that does so (KoD, Ch. 5). When Galina betrays Faile, it is Theril who saw the building fall and went for help (KoD, Ch. 29).
