She is described as short and slightly plump with smooth copper skin, dark eyes, and long glossy dark hair. She was attractive, but not beautiful. Her name and skin tone suggest that she was Domani.
She was called out of exile to lead a group of fifty or so Aes Sedai to destroy the Black Tower and to gentle and hang every man they found. Notably, this was outside of Tower law, and extremely similar to what she was exiled for after the Aiel War.
Elaida abandons the Aes Sedai sent to capture the Black Tower, including Toveine, at Alviarin's suggestion .
Her time at the Black Tower was not easy. She was roughed up by the other Aes Sedai who accompanied her, who blamed her for their capture. Carniele healed Toveine on Logain's request after she was beaten by the other sisters.
Logain's other bonded Aes Sedai, Gabrelle, told her that the captured sisters must unite and that they two would submit to the the strongest Aes Sedai there (Desandre and Lemai).
She was captured along with Logain and turned to the Shadow by Mazrim Taim, Black Ajah, and thirteen Myddraal. Pevara noticed that when a woman is turned by male channelers, it is faster.
After the confrontations in the Black Tower between Taim's forces and Logain's forces, the whereabouts of Toveine became unknown. Logain has released the bond ordering to kill her and the other turned Dreadlords.
