The Aes Sedai are a society in the fictional universe of Robert Jordan's The Wheel of Time book series. The Hall of the Servants was the center of Aes Sedai power in the Age of Legends, analogous to the White Tower in the Third Age. It's unclear if the name referred to the organization of Aes Sedai as well their headquarters (as in Lews Therin Sedai of the Hall of Servants). The Hall of the Servants was located in Paaran Disen, which was also the center of world government at the end of the Second Age. The leader of the Servants was known simply as the First Amongst Servants. He or she wore the ring of Tamyrlin as a symbol of their leadership. Tamyrlin was the first person to channel the One Power, and the ring may have been a construct of his or hers, perhaps even the first angreal. Just before the War of Power, Lews Therin Telamon was First Amongst Servants.
