You are walking through a field when suddenly you fall into a deep pit. Fortunately—miraculously—you have not broken any limbs. Though you must have fallen thirty feet, you have only a small scratch on your arm to show for it. You cannot see this scratch—it is so dark inside the pit that you can barely make out your own hands—but you can feel the sting of it just below your elbow.
Patting the ground around you, you discover what feels to be a shoe, a skull-sized rock, a matchbook, and a pile of wood.
