Rethe

Rethe is featured in Kvothe's education during his training with the Adem. She is the key figure in our current understanding of the nine and ninety stories told by Shehyn. The tale begins with the description of the first Adem school and details the journey of Aethe, and his mastery of the wind. Rethe was a challenger to Aethe and despite Aethe's doubts, she soon became his finest student. As time passes Rethe challenged Aethe to a duel, featureing Aethe in a grove of young swaying trees. Contrary, Rethe sat atop a hill, with no cover. Rethe had mastered the reading of the wind as Aethe had, and upon being shot by Aethe wrote four lines of poetry on a piece of silk; she then released it only to have the wind carry it and press it against Aethe's chest.

The poetry read:

"Aethe, near my heart.
Without vanity, the ribbon.
Without duty, the wind.
Without blood, the victory."

After this fight, Shehyn reveals that Rethe then dictated the nine and ninety tales saying that there would be a one hundredth tale when she awoke, but prior to waking she perished. (from Kingkiller wiki)
