There are also a number of details of the setting the players don't know.
Spoilers begin here.
- All of the teaching staff are Soldiers of Laurence (and thus Symphonically aware).
- They are also all highly skilled martial artists (yes, that Bruce).
- Numinous Corpus: tentacles is not such a good idea. Remember Laurence's Word?
- Most, if not all of the Superiors have covert agents among the girls. Some are better-hidden than others.
- There is little physical danger. The greatest risks are of exposure or humiliation.
Spoilers end here.
