Serapis listened to his wife's take on the situation. "Not a bad idea." He raised his voice. "Attention, everyone! We don't know who did this, and it doesn't matter! Every student present here will stay here during an hour of their free time tonight to clean this place up! And I want it to be better than it was before!"

Jorn winced at that announcement, but then thought about it. Less time for amorous advances from a certain female dwarf could only be a good thing. At least until this little crush ran its course. 

"And if anyone refuses or shirks their cleaning duties, they will have their normal chores doubled for a month! Understood?! This is absolutely unacceptable behavior! Not only does it reflect poorly on us as a school, but it shows us that there are some students who are more interested in abusing their powers than using them for good! The only good news is that you all have some time today before you have to clean up this mess, so for now, please proceed with what your regular schedules. If anyone wants to confess or has information you think I should know, tell me as soon as you can."

Aurelian briefly considered it, but then he thought better. Now was not the time to anger the other students. Although he was happy that the lizardfolk got some comeuppance. 

Serapis turned back to his wife. "How was that? And do you think Arjun had anything to do with it? I'd hate to think that our son was in on it."
