Elswell is an Aes Sedai of unknown Ajah.
Activities[]
She participated in the Last Battle and survived.
She is one of four Aes Sedai, the others being Saerin, Rubinde and Yukiri, trying to convince Rodel Ituralde to take the throne of Arad Doman after the Last Battle.
Speculation[]
All the Aes Sedai that persuaded Rodel Ituralde to become King and Cadsuane Melaidhrin to become Amyrlin were Sitters, except Elswell. However, the situation might suggest that Elswell is also a Sitter and, if so, she would be the unknown Sitter of the Blue Ajah.
During a Q&A with Brandon Sanderson, he said, with no absolute certainty, that this theory is possibly correct.
