"I don't think it's any of your concern as to why the Headmaster sent you all here, Rivers." Aurora was not in a good mood. Even those who knew her well enough to see the difference between her levels of annoyance could tell she was in an exceedingly bad mood. Someone (and Merlin save them when she found out who) had stolen from her, another student had been murdered and her own students were running about the castle without a care in the world.
Aurora lingered near the doorway to the dungeons. True to her word she had locked the doors exactly five minutes after her journal post and changed the password. Little did her students know that she had no intentions of leaving for quite some time.
