Marith is 5'6" tall and has not yet achieved the ageless look.
Strength in the One Power Edit
Marith Jaen was Amyrlin when she was a novice, and it was uncomfortable for her to have the same first name as such a tough Amyrlin.
She had a habit of making observations of people and events that would have been better kept to herself.
When she was still Accepted, Elayne threw a cup at her, for which she was switched.
Marith's Ajah is never identified in the main books of the saga.
Of the thirty-nine sisters sent to kidnap Rand, 15 were of the Red Ajah. According to Galina Casban, the remaining sisters were 10 of the Green Ajah and 12 of the White (the last two are Nesune e Coiren, a Brown and a Gray respectively).
But Marith's Ajah is identified as Brown in "The Wheel of Time Companion", contradicting the description given by Galina in the Book.
