Egwene al'Vere, after learning the Black Ajah's member lists from Verin Mathwin's secret notes, returned to the rebel camp. After assembling the Rebel Hall of the Tower and swearing the three oaths on the Oath Rod and thereby proving herself not a Darkfriend, she claimed to know the names of the Black Ajah's members, several of them found among the rebels. Among the Hall's present members, Moria Karentanis, a Sitter of the Blue Ajah was discovered as Black, shielded and blocked, the same happening to Egwene's Keeper of the Chronicles, Sheriam Bayanar. The Hall then proceeded by forsaking and reswearing their oaths on the Oath Rod in turn, in order to prove themselves friends of the Light. Afterwards, they had all the Rebel Aes Sedai come by Ajah to repeat the process, resulting in over fifty Black sisters captured out of the estimated seventy that were in camp at the time.
Afterwards, back in the White Tower and in control of both factions as the true Amyrlin Seat, Egwene repeated the process within the Tower. Mesaana, however, was not found. Egwene was aware of her presence due to Verin's warnings in the notebook and vowed to hunt her down if she had dared to remain in the Tower.
