Trumpkin

Trumpkin the Dwarf is the narrator of several chapters of Prince Caspian; he is one of Caspian's rescuers and a leading figure in the "Old Narnian" rebellion, and accompanies the Pevensie children from the ruins of Cair Paravel to the Old Narnian camp. In The Voyage of the Dawn Treader, we learn that Caspian has made him his Regent in Narnia while he is away at sea, and he appears briefly in this role (now elderly and very deaf) in The Silver Chair.
