As you have been travelling deeper into the forest, the amount of
sunlight filtering through the trees has gradually become less and less.  In
this section of the woods the trees are so close together that they form a
dense canopy, darkening the area.  Scraggly thorn bushes and strange patches
of fungus cover the forest floor, and your movement is severely limited. 
The trail has almost disappeared, perhaps it would be a good idea to turn
back.
