From: Alford Stone
Description: Still, I am convinced that the "shadow" had nothing to do with this. A notebook had fallen near the apparatus. It wasn't particularly suspicious, but there was a formula written inside. Here, take a look at this.
Completed: This note definitely belongs to a scientist. It is handwritten, but not illegible. This is how he was able to activate the energy device. Someone at the academy must have modified this device for some purpose.
