As you enter the third cave, you are suddenly stopped by Sigvards outstretched hand. Confused, you look down and see the massive expanse before you. The size of this passage is so immense, not even the beam of your flashlight can reach its walls, floor, or ceiling. In the endless void of black, you notice an incredibly narrow rock bridge. Not even a full foot across, it is surrounded by the chasm on either side. You cannot see where it leads, but Sigvard urges you to cross it. Desperate to escape, you agree, and begin to shimmy your way across the narrow path. Boris follows close behind, with Sigvard guiding behind him. You are about halfway across when Boris freezes. You notice his legs shaking uncontrollably, and his eyes transfixed on the void “You know,” Boris says, “Im quite scared of heights.” You urge him to keep moving, both you and Sigvard offer your hands for balance, but it's too late. Boris looks up at you and takes one more step before he wavers and slips into the darkness. You hear a quiet yelp, but never hear him reach the ground. Together, you and Sigvard make it safely across, and using his expertise, you are guided safely to an exit.
