Jacob
Now this was the sort of thing Jacob had been waiting for from the start. The chance to kill as many as he could before this was all over - and he certainly planned on making very good use of the time he had available to him. His only concern for those wearing the bright armband was that he not hit them, always conscious of the vow he'd made to the late Headmaster.
But beyond that, Jacob didn't pay attention to them - he cast curse after curse, watching each hit their mark with perfect precision causing the bodies to fall to the ground lifeless. There was only one thing he might have changed about all of this, and that was the time he was able to spend on each kill. Even here there never was the proper amount of time to truly enjoy it, but Jacob let himself focus instead on the thrill of the dark magic flowing easily though him.
It was all over far too quickly in his mind, bodies littering the once empty grounds, both friend and foe. And he sighed shaking his head brushing off any dirt that had ended up on his robes and setting himself to right again, giving no concern to the few bumps and scrapes he'd earned himself along the way.
