Lieutenant Graves

Lieutenant Graves is an elite black knight who stands guard on the second floor of the Black Knights Fortress. He reports the failure of the circle to locate the witch and the artefact. Telling him that you will deal with it will lead to him asking to take command of Sir Owen, insisting on it. Sir Owen knocks him out, and his body is searched to reveal 250 coins. You can either choose to let Sir Owen kill him or hide his body somewhere. If the latter option was chosen, he will have been crammed under his bed, if interpreted that way.
