|In 50 AC or 51 AC, beyond the Wall
Ser Raymund and his sworn brother of the Kingsguard, Ser Olyver Bracken, abandoned King Maegor I Targaryen in 48 AC when Prince Jaehaerys made his claim for the Iron Throne. Since both men had broken their Kingsguard oaths by not protecting Maegor, and Jaehaerys did not wish for oathbreakers to serve him, after taking the throne he offered them the choice of execution or taking the black. They both chose to join the Night's Watch.
The Lord Commander of the Night's Watch gave Ser Raymund command of Sable Hall and Ser Olyver command of Rimegate, with orders to restore the crumbling forts of the Wall. However, in 50 AC, Raymund and Olyver led a rebellion of former Faith Militant in the Watch, trying to make themselves lords of their castles. Lord Walton Stark rode north to aid the loyal brothers with ending the mutiny. After Sable Hall was informed of Olyver's execution at Rimegate, Raymund and his rebels fled beyond the Wall to join the free folk. Lord Stark marched north in pursuit, but was slain in the haunted forest by giants. Half a year later, Raymund's head was delivered to Eastwatch-by-the-Sea by a wildling chieftain, who claimed his people had eaten Raymund's rebels.
