The Black Tower is located in a rural area near Caemlyn. Although it is just a reworked farm, it is the headquarters of the Asha'man, the organization of male channelers started by Rand and primarily trained by Mazrim Taim. It was named the Black Tower in contrast to the Aes Sedai's White Tower.

The Black Tower grows to a town with an ordinary-looking village in the middle but it is surrounded by a four square mile black wall.
