Hemlock's attentions had not only healed Aelfric's body of its wounds but also given him curious sensitivity. Aside from the voice in his mind, he felt things in the natural surroundings: the presence of beasts, the whispers of trees to the overcast skies, anger in the earth and sea. Ravens followed him around as they did wolves. And he had developed a rough ability to see in the dark.
