In "The Wheel of Time Companion" Aisha's level of strength is described as 14(2), putting her among the most influential sisters of her age.
Aisha was 282 years old when she died. She was born in the year 698 NE and went to the Tower in 714 NE. After spending seven years as Novice and six as Accepted she was raised to the shawl in the year 727 NE.
Her name indicates that she was an Illianer.
She had a Warder.
She was one of the women chosen to be Tamra Ospenya's Searchers for the Dragon Reborn. She was said to be one of the most strict interpreters of Tower Law ever, said to show no mercy whatever the case may be.
It has been speculated that also she, Valera Gorovni and Ludice Daneen were strong in the One Power. This has been speculated partially due to the strength that Meilyn Arganya and Kerene Nagashi possessed, having led some speculators to the belief that Tamra was not only looking for women strict and of great abidance to the law, but also for those strong in the One Power.
