  === Maester Aemon ===
  Aemon Targaryen is the older brother of Aegon V Targaryen, the third son of Maekar I Targaryen, and a member of the Night's Watch. Decades before the events of ''A Game of Thrones'', he was sent to the Citadel in Oldtown on the orders of his grandfather Daeron II, who felt there were too many Targaryens, and became a Maester (one of an order of scholars and healers). He was later offered the throne of the Seven Kingdoms after the death of his father Maekar, but ceded the rule to Aegon and joined the Night's Watch. By ''A Game of Thrones'', he is elderly and blind, but provides guidance to the men of the Watch. In ''A Feast for Crows'', Jon Snow sends him to the Citadel by sea, but Maester Aemon dies on the voyage between Braavos and Oldtown.
  In the HBO television adaptation, he is portrayed by Peter Vaughan.
