The sounds seem to be coming from off the direction the path is going in, though knowing how it winds it could go anywhere. But, from the look and sound of things, simply cutting through the trees seemed fastest.
Yarra and Jan had a rather interesting time off the path, but thankfully didn't have to go far. There was only so much climbing, ducking, and nearly-crawling one could do without getting uncomfortable. Of course, it wasn't that much worse than the so-called path was.
After only having to move about fifty feet off the path, still within sight, though vaguely, of the path, another clearing can be seen. Its still a bit away, but there are enough trees to provide cover to look on without, hopefully at least, being seen. Black objects that are probably buildings like you saw before are pocketed here and there, but what catches your eye are the various...figures, of a sort.
There are a countless number of them, and you can see through them even from a distance. They don't seem solid at all, and though they are vaguely human-shaped, they are all a blue colour that makes them easy to see amongst the greens and blacks around them. It is still impossible to hear the exact words being spoken, but its obvious they're words now and that the things are speaking to one another.
