Somewhere in the academy, a Naberius, tame at the moment, was being readied for transportation away from the exorcists in training. Naberius were once used to fight demons, but something in their making somehow coerced them to turn against the exorcists. It had been forbidden to make one for years, yet someone this one had been made. It would be useful, until it turned. And then it would be killed...

Oliva looked up, with a frown, hearing cries, and shouts. She turned to her students, about to say "stay here" when the door to the training room burst open, and then Naberius was there, clearly rabid. And before Oliva could do anything, could even begin to think of a ritual to kill the demon, Lorenzo had drawn his sword, in his gloved right hand, charging the monster from One side.

She drew the blade before she could even think what she was doing, and Oliva cried out "no!" But it was too late.
