Black Ajah
From A Wheel of Time Wiki
The Black Ajah is an unofficial and secret Ajah, comprised of sisters who hide in other Ajahs and who have forsaken their Three Oaths in order to serve the Dark One. They have their own set of Oaths that remain mysterious, aside from one prohibiting them from revealing other Black sisters, the existence of the Ajah, or the Ajah's current plans.
[edit] Organization
The Black Ajah is administered by a Great Council of Thirteen. It is thought that the Black Ajah was founded by Ishamael himself, who was not bound completely into Shayol Ghul as the rest of the Forsaken were. Reports of its existence were only recently accepted by other sisters when Liandrin, a Red, fled the Tower along with twelve other sisters, stealing several ter'angreal and killing a number of Tower personnel. The Black Ajah is currently controlled by Mesaana, who is undercover in the White Tower.
Black sisters are organized into hearts, a group of three women who know each other and who in turn each know one sister from another heart. Only those very high in the Council of Thirteen, and then perhaps only the highest, know the identity and location of every Black sister.
