During his time as castellan, Ser Harbert counseled Maester Cressen to kill Patchface because he thought that the fool was suffering due to his deteriorated mental state. Cressen disagreed and won the argument. Stannis Baratheon once found a wounded goshawk, which he named Proudwing, and nursed it back to health. He tried to teach the bird to hunt but had no success. Harbert persuaded Stannis to abandon the goshawk.
