The routes are as follows:
The first route is dark and nondescript save for the sound of birds.
The second route is dark, but up ahead there is a bonfire.
The third route is much better lit than the others. It leads to a cabin.
The fourth route appears to have large potholes in the path.>>542167

It's unclear what the source of the magic is. Without a source, there's nothing to aim at. What you're doing in akin to a cat striking at the red laser dot instead of the laser pointer.
The path does seem to brighten slightly, though.>>542165>>542168>>542171
You come to a monstrously sized pit. You can edge around it, but the trees grow quite closely. Roll dex if you want to navigate the edge without flying.
