  > Go downward
  Inside the Glass Maze (you are flying)
  You are inside a huge cubical maze, shimmering with light from an unseen source above. Thanks to your sonar-like bat senses, you can tell that there are surfaces below you, to the north, to the south and to the west.
  
  After a moment of futilely flapping your arms, you realize that the fweep spell has worn off. You fall several feet to the ground.
  
  > Fweep
  With keen disappointment, you note that nothing has changed. Then, you slowly realize that you are black, have two wing-like appendages, and are flying a few feet above the ground. Thanks to your sonar-like bat senses, you can tell that there are surfaces below you, to the north, to the south and to the west.

  Hollow (you are flying)
  The maze opens here onto a tiny outdoor plateau, completely surrounded by towering cliffs. The only way out is back through the dazzling archway of glass to the west.
  Near the glass arch is a small rectangular brick structure. The center of the structure is a hole about a foot wide, leading down into darkness.
  There is a parchment scroll here.
  
  > get the scroll
  You're batty!
  
  > wait awhile
  Time passes...
  
  After a moment of futilely flapping your arms, you realize that the fweep spell has worn off. You fall several feet to the ground.
  
  > get the scroll
  As you take the scroll, a deep and evil laugh rumbles around the hollow. You hear a sliding, grinding noise and turn just in time to catch a flicker of light from within the glass maze, indicating that its transparent panels have shifted around.
  
  > read it
  The scroll reads "swanzo spell: exorcise an inhabiting presence".
  
  > Fweep
  With keen disappointment, you note that nothing has changed. Then, you slowly realize that you are black, have two wing-like appendages, and are flying a few feet above the ground. Understandably, you dropped everything you were carrying.
  
  > examine the structure
  The structure is about two feet on each side, and extends up from the ground about three feet. Except for a large quantity of soot around the opening, it looks a lot like a small, rectangular well.

  > put the scroll in the structure
  The parchment scroll disappears into the shaft.
  
  > go to the west
  You are inside a huge cubical maze, shimmering with light from an unseen source above. It is impossible to tell if the walls and ceilings around you are glass surfaces or openings. Since you are standing on something, the floor must be solid, but it is virtually invisible and you feel as though you were walking on air.
  
  From outside the maze, you hear the bellowing of a ferocious dorn beast!

Thanks to your sonar-like bat senses, you can tell that there are surfaces above you, below you, to the north and to the south.
  
  The dorn beast rushes after you. Its ear-splitting bellowing resounds throughout the glass maze.

  The dorn beast rushes after you. Its ear-splitting bellowing resounds throughout the glass maze. Suddenly, the dorn-beast realizes that it is galloping through midair, and gives a surprisingly high-pitched squeal. It claws frantically at thin air, trying desperately to invent dorn beast flight. You happily notice that dorn beasts do not so much fly as plummet.
