Wise Ones are Aielwomen of wisdom. Most, but not all, of them can channel, and some of them are Dreamwalkers. As part of becoming a Wise One, an apprentice must journey twice to Rhuidean, once to the learn the secret of the origins of the Aiel and once to see their possible futures in another ter'angreal. By tradition, Wise Ones do not engage in battle, and they stay away from Aes Sedai. Slaying a Wise One is a heinous crime among the Aiel, on par with killing a pregnant woman, a child, or a blacksmith.
