After being attacked on Harpy Island, Graham brought the wounded Cedric the Owl to the Ancient Mariner's Hut for help. When he discovered the old man's hearing problem, he gave him a conch shell to help him. At last able to understand one another, the Ancient Mariner used a poultice to help heal Cedric. Afterwards, Graham told him of his quest and the hermit called upon Pearl to lead the king to Mordack's Island.
The Ancient Mariner is a character who appears in King's Quest V: Absence Makes the Heart Go Yonder.
