Nesita is an Aes Sedai of the Red Ajah. She is also secretly part of the Black Ajah.
History
She stands higher than average in the Aes Sedai hierarchy, being able to create a suitable gateway on her own, which implies to be above level 22(10).
Appearance
She is plump and blue eyed and as mean as a snake with an itch.
Activities
She is sent to collect tributes for Elaida a'Roihan's White Tower and collected a tribute from Aesdaishar in Chachin. Ashmanaille, sent by the Rebel Aes Sedai to do exactly the same thing, was told by the shambayan that the Tower had already collected its tributes, and deduced that the sister from Elaida's Tower was Nesita.
She is one of the Red Ajah who follows Egwene al'Vere around the White Tower and feeds her Forkroot. When Egwene tried to refuse the tea, Nesite helped pour it down her throat with a funnel.
In Verin Mathwin's book given to Egwene, Nesita is listed as a member of the Black Ajah.
