Gillemin Brandybuck believes the great tree he found is at the centre of the stirring of the Old Forest.
'You are one for a good tale I see. Well then, a good tale I shall tell, I hope. The tree did not look alive, rotten to the core I think and seeking only vengeance. Mayhaps it was one of the tenders of the past spooked by some feeling of dread that washed over it or some such. I know only that it lay beyond the spiders that took my pack.
'It was foul and terrible to see, a great blight in the forest. If something in these woods has stirred them to something greater than mischief, I would first look there.
'You will need to cross the river here and search within the hollow where the spiders make their nest. That was the last spot I saw the tree.'
The spider nest lies near the Willow Glade, to the south of Gillemin's old camp. Search there for signs of the angered tree.
Gillemin told you that the source of the forest's unrest likely lay within the spider hollow beyond the Withywindle River to the south, within the Old Forest.
Return to Toly Brockhouse near the Gate that borders the Old Forest and Buckland.
The dead tree has been slain, and though there is still great evil stirring within the wood, the borders of Buckland should see some manner of ease. You should return to Gillemin Brandybuck with the news.
