Old Forest
When Gorhendad Oldbuck and his clan of Hobbits settled Buckland, they began to encroach upon the Old Forest, thus re-awakening its hostility to two-legged creatures that had first been aroused back in the Second Age. The settlers soon found themselves under threat from the forest. They felt that the trees of the Old Forest were in some manner 'awake', and were hostile. The trees swayed when there was no wind and whispered at night, and they daunted intruding hobbits by tripping them, dropping branches, and driving them deeper into the forest. Deep within the Old Forest was the Withywindle Valley, which was the root of all the terrors of the forest; it could be a dark, evil and malevolent place.
