Humphrey is Sir Robert Norramby's horse. He lives in a small stable at Ulfstead Castle.
The stubborn old horse was permitted to assist Sir Robert Norramaby and Millie on their quest to reclaim King Orry's Lost Sword. Humphrey was startled by a dynmite blast at the Blue Mountain Quarry, causing him to gallop away in fright. He spent a major portion of the day blocking Ivo Hugh's path. Yet, nobody knew how he got there!
