|The Old Oak's Grave|
'Well now, as I said before, I think that nest of spiders I found has something to do with all the queerness stirred up in the Forest. But there are too many spiders for me to deal with myself, and the Bounders will only come with fire and axes.
'If you could make your way into the heart of that nest, maybe you can find out a little more. The spider nest is south across the Willow Glade.
'I was only able to make it to the outskirts of the nesting ground before the spiders chased me away, so you'll probably want to gather some friends.'
Gillemin Brandybuck believes the great spider nest he found is at the centre of the stirring of the Old Forest.
