Mistress Anford is a clerk in the Royal Palace in Caemlyn and one of Halwin Norry's most trusted. She is graying and has a small White Lion stitched on the breast of her neat brown dress (KoD, Ch. 17).
In the Map Room, where she and five other of Norry's clerks work with six of Mistress Harfor's messengers, she approaches Birgitte with the report on available fodder she was asked for. Birgitte says she will look at it later and has Mistress Anford take the others outside. She does as instructed, giving them only enough time to stopper their ink jars; they are all accustomed to leaving the room when Elayne and the others want to talk privately (KoD, Ch. 17).
After Elayne has been captured by the Black Ajah, Birgitte meets with Guybon and Dyelin in the Map Room to tell them as much and prepare to rescue her. Upon hearing this, some of the messengers and clerks present begin murmuring until Mistress Anford silences them with a sharp order to see to their work. When Birgitte informs Guybon that they will be facing at least two Darkfriend Aes Sedai, likely more, Guybon is glad that they have their own Aes Sedai. Birgitte tells him they are all dead except for Elayne, causing Mistress Anford to have to steady herself instead of reprimanding a clerk who knocks over an ink jar (KoD, Ch. 32).
