|Alias||The grey pup|
|Title||Maester at Coldmoat|
|Book(s)||The Sworn Sword (appears)|
Cerrick came from the Iron Islands. The maester designed the dam of the Chequy Water, which caused a conflict over the river between Lady Rohanne Webber of Coldmoat and Ser Eustace Osgrey of Standfast.
After Ser Duncan the Tall defeated Ser Lucas Inchfield in a trial by battle, Maester Cerrick treated his wounds. Cerrick was able to resuscitate Duncan after he had drowned in the river during the battle. Duncan's squire, Egg, worried about poison, forced Cerrick to first taste anything he wanted to give the knight while Duncan was still unconscious.
