Cover Story for Previous Inactivity
We have a list of possible options for why the student characters haven't been active previously:

1. They couldn't, or just haven't, bought a Legens,


2. Mr. Filch or another staff member confiscated their Legens,


3. They misplaced their Legens,


4. They haven't woken up yet (Future Students),


5. They've woken up, but are disoriented or generally out of it (Future Students),


6. They're weakened to the point of not being able to leave the Hospital Wing (Future Students),


7. They left the Hospital Wing but soon had a relapse (Future Students).

Note: This list isn't exhaustive by any means. If you have any ideas to account for the inactivity of the student characters, please comment below. We'd love suggestions! Any plausible alternative just short of being an exchange student at Beauxbatons or Durmstrang will be considered.
