The forest is, indeed, a dark place, and although it has never been inhabited and, since your grandfather has memory, very few men have dared to enter it, you see it still has some apparently natural routes that lead inside of it.

After walking for a while you find yourself in a considerably sized forking-path clearly showing three different paths.
