A hidden city deep in the Aiel Waste, built by the Jenn Aiel (the Clan That Is Not). Aspirants to clan chief or Wise One must enter Rhuidean and pass through ter'angreal that reveal the Aiel's true history - that they were once pacifist servants of the Aes Sedai who broke their covenant. Many who enter do not survive the revelation. Rand al'Thor's visit to Rhuidean marks him as the Car'a'carn, the Chief of Chiefs prophesied to unite the Aiel.
