Matt looks about, seeing that a few desks are turn over, as if knocked down.  The rest of the room looks decidedly normal, with the teacher's station all proper, the last classes notes still on the chalkboard.  Apparently, math was the order of that day.<br/><br/>Sliding his laptop out, the would be sorcerer gets an idea.  Earlier he found some ley lines, but none that went through the school.  Unless there were shrines nearby.  Powering it up, he connects to the local wireless, and rechecks the local area.  And indeed, there are two old ones about exactly a mile out from the school.  However, there's no history of them being tampered with.  At least not in the last 100 years, and that's the only way the main lines would cross to create an opening.
