Asne was a typical Saldaean with a bold nose and tilted eyes.
She was from Saldaea.
She was Aes Sedai for over a hundred and thirty years.
After fleeing the White Tower, she and the others in Liandrin's group went to Tear and worked for the Forsaken Be'lal. They tried, unsuccessfully, to trap Rand al'Thor just after he released Callandor. After this failure, she fled to Tanchico to try and steal the male a'dam from the Panarch's Palace. This Black Ajah plan was also foiled, by Elayne Trakand and Nynaeve al'Meara.
After Tanchico they went to Amadicia where Moghedien took charge of the group. There Liandrin tried to take advantage on a wounded Moghedien, but the Forsaken was more able than her, leaving Liandrin severely punished, demoted and shielded permanently. Upon leaving Liandrin's group, Moghedien placed Eldrith in charge, as the strongest in the One Power of the remaining sisters.
She then traveled to Samara with Chesmal Emry, Eldrith Jhondar, and Temaile Kinderode after Moghedien ordered Temaile to Ghealdan. When Eldrith Jhondar's Warder Kennit arrived, they fled to Caemlyn.
After fleeing Samara, Asne stopped masking her Warder bond so that they could find her. She intended to keep the presence of her Warders a secret, holding them in reserve in case she needed protection.
She walked in on Elayne, Vandene Namelle, Sareitha Tomares, and Careane Fransi trying to arrest Mili Skane, Falion Bhoda, and Marillin Gemalphin. To overcome them Asne used a terangreal that she had found hidden in Moghedien bedroom in Amadicia. She used it to stun all the opponents.
Vandene, Sareitha, and Careane were all killed and Elayne was taken captive. Working with Chesmal, Falion Bhoda, Temaile, Marillin Gemalphin, Eldrith, and Lady Shiaine, Asne attempted to try and flee from Caemlyn with Elayne. Birgitte immediately organized a rescue expedition. Asne opened their way using a terangreal that produced balefire. In front of it Birgitte persuaded the Windfinders to intervene and so Asne was killed by lightning thrown by a circle led by Chanelle.
