A group of guys had been bullying you for a while. Nobody imagined they would go this far, even as a joke. Now you're brutally beaten in an empty classroom and it's not just that: they take your blood and use it to draw a summoning circle. And it works. The room freezes as he appears in the center of the circle. Your attackers stand there in a mix of shock and horror while you sit in the corner nearby, barely conscious.
