You move forward, cautious and quiet, rolling your feet through clusters of rank weed, avoiding the bubbling pits of steaming mud. After what seems like an hour of darkness deepening under ever larger trees, you begin to imagine a presence nearby, off to your left and behind you. You can almost hear the padded footsteps, almost feel the silent breath. You stop to look back and see nothing but dense foliage gently wavering in the dusky light. Slowly, you nock and draw an arrow, but you’re unsure. Is it just your nerves playing games with you?
