According to Tom Bombadil, at the dawn of time, long before even the Awakening of the Elves, trees were the only inhabitants of vast stretches of the world. Because the Elves awoke far in the East, it was still a considerable time before any other beings spread into the vast primeval forests of western Middle-earth. A handful of trees survived from this time until the present day, who are angered at the encroachment of Elves and Men and their dominion over the earth; trees who bitterly remember a time long ago when they were as Lords of vast regions of the world. Bombadil relates that of the corrupted trees of the Old Forest, none were more dangerous than the Great Willow; his heart was rotten, but his strength was green; and he was cunning, and a master of winds, and his song and thought ran through the woods on both sides of the river. His grey thirsty spirit drew power out of the earth and spread like fine root-threads in the ground, and invisible twig-fingers in the air, till it had under its dominion nearly all the trees of the Forest from the Hedge to the Downs.
