Crossroads
The claustrofobic feeling lessens as the path widens, giving you more space to breathe. You check out what's around you. To your left is a gap between the trees where a road once led to the west. What remains is an animal trail. To your right the dank smell of rotting marshland doesn't very much appeal to your senses. And straight ahead the road leads on, climbing higher and away from the swamp. 

Turn left and investigate the animal trail
Or, keep on going straight ahead.
