Rianna Andomeran

General

Rianna Andomeran is an Aes Sedai of the White Ajah who is also a member of the Black (TDR, Ch. 25). She has black hair with a white streak above the left ear (TDR, Ch. 25), which she touches when nervous (TFoH, Ch. 18). She is from Kandor (TDR, Ch. 49).

Along with Chesmal and Liandrin, she is one of the three Aes Sedai that Amico knew before leaving the Tower (TSR, Ch. 5).

She is able to kill with the Power, though her Talent is not as strong as Chesmal's (TSR, Ch. 38).

Liandrin considers her a coldly arrogant killer (TFoH, Ch. 18).

Falion thinks she has odd, “unsound notions on several points of logic” (ACoS, Ch. 17).

She leaves the Tower with Liandrin and the others and heads to Tear (TDR, Ch. 13).
She is present when Liandrin captures Nynaeve and is backhanded by her. After this, she wants to kill Ailhuin, but Liandrin stops her (TDR, Ch. 51).
She goes with Liandrin to Tarabon (TSR, Ch. 6).
She flees Tarabon for Amador where Moghedien gives her instructions after which she leaves the group (TFoH, Ch. 18). Her current location is unknown.

Always you kill too quickly, and only the Great Lord can make use of the dead (Liandrin to Rianna, The Dragon Reborn, Chapter 51).
