Appearance and personality Edit
She was plump and had a round face with dark eyes and long dark hair. In Elaida’s opinion, she was one of the most arrogant of all among the sisters.
Being a Sitter in the Hall means that Sedore was also a high-ranking sister and a strong channeler by Aes Sedai standards. Her strength level is described by "The Wheel of Time Companion" as 19(7). Thus she was able to open a gateway alone to Travel.
When Sedore died, she was 187 years old. Born in Tear in 813 NE, Sedore went to the White Tower in 829 NE. After spending nine years as a novice and seven years as Accepted, she was raised to the shawl in 845 NE.
She was elected Sitter in 961 NE.
She was one of the Sitters meeting with Elaida when Alviarin Freidhen returned to the White Tower. Elaida made her nervous, and so did mention of forkroot.
A list of Black Ajah members given to Egwene al'Vere by Verin Mathwin confirmed that Sedore was a Darkfriend, but she managed to escape the Tower. In fact, she was a member of the Black Ajah Supreme Council, and was one of only three women who knew Alviarin's identity as Black Ajah head. The others were Galina (Alviarin's second) and Velina. (Note: The Wheel of Time Companion has conflicting entries on this; Velina's entry says that Sedore knew Alviarin's identity, but Sedore's own entry states otherwise).
If she was in her own body while killed in Tel'aran'rhiod, which Darkfriends tend to do, her soul would be obliterated. Very likely, she was using one of the dream ter'angreal stolen by Sheriam Bayanar and given to Mesaana, which would not have brought her there in the flesh.
