She is described as stout, but graceful. She had wide shoulders and arms as thick as most men's.
Careane was fairly weak in the One Power, the weakest sister among the rebel Aes Sedai embassy to Ebou Dar. Her level of strength is described by "The Wheel of Time Companion" as 27(15) which is a middle level in Aes Sedai hierarchy. With this level of strength she is unable to open alone a suitable gateway to Travel.
She was from Arad Doman. She was a novice for two years with Zarya Alkaese, now known as Garenia Rosoinde. She had three Warders, Cieryl Arjuna, Venr Kosaan and Tavan. We don't know if one or more of them was also a darkfriend.
Ebou Dar Edit
She Traveled with the the group led by Nynaeve al'Meara and Elayne from Ebou Dar to the Kin's farm with the Bowl of the Winds. It was Careane who revealed her face at the Kin's farm, resulting in the panic and flight of many of the women there.
Adeleas' murderer revealed Edit
While inside Careane was identified as Black Ajah and is presumed to be the murderer of Adeleas Namelle and Ispan Shefar, and likely the murderer of some members of the Kin. Vandene stabbed her with a knife as punishment for the murder of her sister. Presumably Careane died from the blow a short time after.
