Doirmanes is a young Cairhienin nobleman who was taken gai'shain by the Shaido. He is very pretty.
Faile thinks to herself that Doirmanes would tell on her if he knew about the other gai'shain's oaths of fealty and would then need to be killed before he reached Sevanna with this piece of information.
