Wiki on Aes Sedai - the history and makeup of Aes Sedai

Accepted
If you are applying for an Accepted character, you must post a paragraph in your history about your time as a novice, as well as a paragraph on your test for Accepted in addition to a paragraph on your history before coming to the White Tower.

Aes Sedai
Aes Sedai require more history, for their early history, their time as a novice, their novice test, their time as an Accepted, their test for Aes Sedai, and further history as an Aes Sedai. Furthermore, you will have to choose an Ajah upon joining. If you wish to roleplay in the White Tower, then the Red Ajah is excluded - they have their own tower in Seanchan.
