heal the scars and change the stars

[Her tone is deadly serious and in the background you can hear people moving and shouting]

LISTEN UP, THIS IS PROFESSOR SENJU!

ANY STUDENTS WITHIN THE LIBRARY WHO ARE INJURED, if you are able, respond to this message. State your wounds, pain level, and location. If you see someone who is injured and unable to respond, RESPOND FOR THEM.

ANY STUDENTS WITHIN THE LIBRARY WHO KNOW HEALING SPELLS, MEDICAL MAGIC, OR BASIC FIRST AID 
Respond to this message and immediately make your way to the barricade at the library's entrance. I will have further instructions for you there.

ANY STUDENT TOO STUPID TO GO STRAIGHT TO THE GREAT HALL
Find a teacher. If you are closer to the library than the Great Hall, get your ass over here. We'll need help with the wounded and debris once the wall's opened.

FAILURE TO FOLLOW THESE INSTRUCTIONS WILL HAVE EXTREME CONSEQUENCES ONCE THIS CATASTROPHE IS OVER.

I don't think I need to repeat myself.

Everyone in the library, remain calm. We'll get through this soon as long as everyone does their part.
