Master of the Old Forest
Old Man Willow
Huorns
Old Man Willow is a vast and ancient willow on the Withywindle in the Old Forest, a tree with a rotten heart and a waking, malicious will whose influence spreads through the whole wood. He trapped Merry and Pippin in his trunk and tipped Frodo into the river until Tom Bombadil sang him to sleep and set the Hobbits free.
