When he reached a small clearing in the midst of the fire, the Mage knelt down and pressed a hand to the concrete beneath him. There was some trembling, then, suddenly, a stone pillar shot up out of the ground and back, aimed at the Reaper. It was so fast that if a fireman blinked he wouldn't be able to spot it. He had to be careful, since the Reaper was hiding around the regular humans. He'll have to separate it from the others somehow. He punched the ground, creating a large hole. He jumped in, closing the hole behind him. He continued to send up pillars at the Reaper, trying to trap it.
