-The right tunnel-

  You decide to follow the right-hand tunnel, and after just a few seconds you realize that this passage ends in a dead end. The light you saw earlier spreads a small platform on which a shimmering moon is enthroned.

  You examine it more closely and you do indeed notice some unusual features. A small, vertical slit spreads across the sphere. There seems to be something inside, but your hands are too big to pry the moon open and you can't find any tools anywhere in the cave that could have helped you.

  You could be reading stolen content. Head to Royal Road for the genuine story.

  You check your backpack for something useful, and sure enough, you find what you were looking for.

  If you know what that is, then follow section 14.
