Turned out the party was in a pocket dimension created by a hag – “Grandmother Otil” – who for whatever reason was collecting people and turning them to kids to run around in this orphanage. She had strict rules for everyone to follow which, of course, the party insisted on breaking. All except Ryybyn.
Ryybyn was really shook by having their powers stripped away and the whole thing reminding them of their strict upbringing. They insisted on laying low because of that one time another friend broke a rule and wasn’t seen again for a long time.
