Shevan was worried about reports of "leashed women" and the possibility that Seanchan had a device to control channelers. Elaida gave her a penance of Mortification of the Spirit and several days of labour (scrubbing floors) as penance .
During the meeting Shevan was adamant saying: "The Brown is quite clear on the historical precedents. You have all read the secret histories, or should have. Whenever the Tower has been divided against itself, disaster has struck the world. With the Last Battle looming, in a world that contains the Black Tower, we can no longer afford to remain divided a day longer than need be."
Shevan was at dinner with Elaida and most of the other Sitters and, wanting to demonstrate her authority, Elaida insults her and the Browns. After, Elaida began taunting Egwene al'Vere and demanded her to stop telling lies about a Seanchan invasion on the White Tower.
Egwene refused and enraged Elaida to the point where she used the One Power on Egwene, drawing blood and sending her unconscious.
Although not mentioned directly, Shevan can be assumed to stand for Egwene to be raised Amyrlin.
She proved herself to being not a darkfriend using the Oath Rod, but she is no longer a Sitter after the reunification.
Shevan was killed in Tel'aran'riod while awaiting in ambush for the Black Ajah. Unfortunately, the Black Ajah attacked outright, killing Shevan.
