“Eagles are not kindly birds. Some are cowardly and cruel. But the ancient race of the northern mountains were the greatest of all birds; they were proud and strong and noble-hearted. They did not love goblins, or fear them. When they took any notice of them at all (which was seldom, for they did not eat such creatures), they swooped on them and drove them shrieking back to their caves, and stopped whatever wickedness they were doing. The goblins hated the eagles and feared them, but could not reach their lofty seats, or drive them from the mountains.”
