She has a crooked nose that was said to have been gotten from fighting with her fists as a girl.
Aeldene is not particularly strong in the One Power. 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 took over as the head of the eyes-and-ears of the Blue Ajah when Siuan Sanche was raised to Amyrlin. One of the agents that reported to her was Duranda Tharne. Only two or three women among the Blue Ajah were meant to know her identity; Siuan herself was unaware of her replacement.
She also attempted to pump out the identities of those agents working in the Amyrlin Seat's network, but the other Ajahs did not wanted the Blue Ajah having access to both networks, so Siuan retained that knowledge.==Notes==
