M'Jinn was one of the great cities of the Age of Legends, before the Breaking of the World. According to the information we have, it was the second largest/most important city of the Age of Legends.
Before turning to the Shadow, Eval Ramman (Balthamel) held a position at an institute of higher learning in M'Jinn.
An Aes Sedai named Zorelle was from M'Jinn. A Da'shain Aiel named Charn thinks about going to M'jinn to accept a proposal of marriage from a woman named Nalla, and to work for Zorelle Sedai.
