Balladare Arandaille was an Aes Sedai of the Brown Ajah. She was raised to the Amyrlin Seat in 115 NE as successor to Edarna Noregovna. She held the position until her death in 142 NE and her office was taken over by Medanor Eramandos (TWoRJTWoT, Ch. 24). During her time as Amyrlin, the Kavarthen wars took place.
"The Amyrlin understands the most complex of creeds and debates, yet in the end she is the servant of all, even the lowest of laborers." (TGS, Ch. 16)
