A short while later, Sirius was battling one of the upper-ranked tier-1 shades. Its four-part jaw snapped viciously at him, but he managed to hold it back with both hands, straining to keep it from closing in on him. He was in a tight spot, and with no other options left, he could only wait for backup, which would be arriving soon.
Most of the aberrations that had come out I. the second wave had already been slain, leaving only a handful. The group had split up to deal with the remaining three shades quickly. Xander, Raiden, and Aurelia went after two, go more efficiency while dispatching them, while Sirius held off the other one. It wouldn't be much of an issue to take care of the first two but Sirius's opponent was the real problem... this particular abomination was of the grade of monster, a horror far stronger than it's peers.
