The Magic Room

1. You have to cast a spell to stop the shadow.
2. None of the spells you memorized from your spell book will help.
3. You would be well off to have written something on the vellum scroll that you found, and brought it along,
4. Though you could have written almost any spell, GIRGOL is the most powerful one available, and GIRGOL will "time stop" the shadow.
5. Timing is important.
6. GIRGOL the shadow as it prepares to jump into the hypercube.
7. Then rearrange the restructuring of the universe to thwart the shadow.
8. You have to take the Magic Room cube out of the hypercube...
9. ...and put in something else, or the universe will be created around nothing; in other words, destroyed.
10. Don't put in a magic item, or it won't change the structure of the universe, and everything will return to as it was.
