Thirty years before the War of the Five Kings, Ser Wynton came within a dozen votes of being named Lord Commander of the Night's Watch. He has been a ranger in the Night's Watch for nearly eighty years. His mental state has significantly deteriorated within the last ten years.
A Storm of Swords
Ser Wynton is among those left behind at Castle Black when Lord Commander Jeor Mormont goes beyond the Wall in search of Benjen Stark and Mance Rayder. As the last knight in the castle, he is made castellan of Castle Black by Lord Steward Bowen Marsh when Bowen leaves to investigate reports of wildling incursions. Wynton seems to have forgotten his appointment, however, and it is the smith Donal Noye and later Jon Snow who command the defense against the wildling assaults on Castle Black and the gates of the Wall.
