" Grummoch said, ‘There is little profit in talking to him yet. These berserks live in a closed world of conflict and brotherhood. It will be long before Knud Ulfson’s ears will be open to the voices of men, for he is in the battle-trance yet, and I doubt whether he could see his hand before his face. That is the way of berserks. "
