She was one of the few Aes Sedai among the rebels that has the ability to create Cuendillar. She finds her slow progress very frustrating.
Egwene notes she has been spending a lot of time with Lelaine Akashi lately.
She was murdered by Aran'gar, who broke her neck with saidin. Kairen is survived by her Warder, Llyw, whose bond was passed to Myrelle Berengari. She was murdered for the same reason Anaiya was; unless incapacitated, they could have exposed "Halima's" lie to have been the secretary of Cabriana.
Her death meant that turning the Southharbor chain to cuendillar fell to the novice, Bodewhin Cauthon, though Egwene
decided to go herself instead.
