Who is Mr. "Dreary" Drury?

Mr. Drury (or Dreary as referred to by Eldric and later Briony) is Eldric's new tutor upon his arrival to Swampsea. He is an American and does not believe in the Old Ones, choosing not to take a Bible Ball with him into the swamp and mocking the very fear that the others have. This results in his being spooked by the spirits and he drowns in the swamp the first time he enters.
