Mass teleportation

The young professor Flynn was urgently rushing about around the school's campus, until he had finally reached his destination. In full force, he barged through the door in front of him.

"Professor Springett!" But as Flynn entered the large empty training room, he realised that the person he was looking for was nowhere to be seen and instead professor Del, Ray's homeroom teacher was inside.

"Sorry about that, have you seen professor Spirngett anywhere?"

Del was currently sitting on the ground with a brush, making several strokes on the floor as if he was drawing something. 

"Today, I don't think I have," Del replied.

"I wonder where she went?" Flynn thought rubbing his head.

"Oh, what's this?" Flynn said looking at the floor Del was drawing on. "Oh I know, perhaps that is the teleportation circle we will be using for the lower classes practical training. It looks really complicated, I could never make something like this."
