Stage Entry
Initial "Does anyone in Class VII actually read these? If I wrote whatever I wanted here, would they investigate the old schoolhouse regardless? Perhaps I should use this opportunity to tell a joke. I know just the one! Two men walk into a bar, Instructor Neithardt and Thomas, perhaps, and one says to the other -- Oh blast it, I'm out of room..." --Principal Vandyck
1 After reaching the fifth floor:
  • We can now go all the way down to the fifth floor of the school. What kind of horrors could await us down there?
2 After defeating Unsurtr:
  • Oh, that kind. We defeated another tough enemy on the fifth floor. That's enough exploration for me for one day.
3 After leaving the Old Schoolhouse:
  • Another month, another floor investigated.
