Nearing the End of the Tunnel                          -      N      -

                                                        -      -      -

The floor is smoothed out here, and the smoothed out corridor makes your
footsteps echo all throughout the area.  The light from the blue globes
glimmer all through the area, making it hard to distinguish how much farther
the passage continues.  The air is very dry here which makes it hard to
breathe.  The corridor splits into two directions, but they look identical
so it is impossible to tell what lies beyond.
