She had long golden hair and pale blue eyes.
Her level of strength is described by "The Wheel of Time Companion" as 34(22) which is an intermediate level in Aes Sedai hierarchy.
Cabriana was a 89 years old Tairen, from a noble house. She was born with the spark in 911 NE and when her ability manifested in 927 NE she was immediately sent to the White Tower, though she went unwillingly.
She was a fast learner who could have moved faster as novice and Accepted had she not spent a good deal of time sulking over being sent to the Tower, because she did not want to became an Aes Sedai. She spent twelve years as novice and seven as Accepted before being raised to the shawl in the year 946 NE.
She was the Aes Sedai that showed Moiraine Damodred and Siuan Sanche their living quarters just after they were raised to the Blue Ajah. Even then she showed the two newly raised Aes Sedai a submissive attitude.
Semirhage had this information passed on to Halima, who claimed to have been Cabriana's companion. Halima told the Salidar Aes Sedai that Cabriana was killed in a fall. But this story generated suspicion among Cabriana's best friends, Anaiya and Kairen, who started investigating and were killed by Halima.
