Ser Cerrick Manderly is the Castellan of New Castle.
Ser Cerrick Manderly was born third son to Lord Wendel and Lady Bethany Manderly née Reed. He was always the strongest out of the three boys, and spent most of his childhood taking part in sword play and training to fight. He squired for the old castellan of New Castle for several years before being knighted. When his brother Wyman became lord of White Harbor, Wyman named him Castellan of New Castle.
