Johnny Peered down the vertical passage and immediately felt a wave of vertigo. How long did it go down for? And what exactly was it? He felt anxiety wash over him, he knew there was a pair of eyes on his back, but he was too invested to give up now.
He got a rope and tied it to the rim of the opening, then with every ounce of bravery he had, he descended into the dark dampness that awaited. There was no going back.
