EWoT:Barashelle was an Aes Sedai during the Trolloc Wars.
She is commonly portrayed as a hero, and lover to her Warder, Anselan, but Birgitte reveals that really she was an Accepted who bonded a Warder before she was raised to Aes Sedai. As punishment her time as Accepted was prolonged three more years, despite the need of new Aes Sedai in the Trolloc Wars time, and also she was forced to pass the bond to another Aes Sedai. Once she was raised, she was finally forced to bond Anselan, a stubborn much older man than her previous Warder, chosen personally for her by the Amyrlin Seat.
The presumed love story of Barashelle and Anselan is detailed in a famous book: The Flame, the Blade and the Heart.
