Twenty feet tall

Everything snapped back into focus, and I swiped at something hot and wet in my eyes. “Okay,” I said. “Okay. Let’s get Grey and get the hell out of here.”
Just then, something that looked vague and lean, and had huge batlike wings, streaked through the air toward us from the far side of the amphitheater. One of its wings faltered, and it tumbled out of the air, hit the marble floor, and started bouncing. The form rolled several times, and when it stopped, Grey was lying there looking dazed. The lower half of his face, as well as his hands and forearms were soaked with scarlet blood.
“Michael,” I said.
We moved together, getting Grey onto his feet between us, and started back toward the entrance to the vault, skirting the hellish heat coming off of the rubble. “Grey,” I said, “what happened?”
“He got smart and shifted down,” Grey said. “My jaws slipped. But something got in his eyes, and I disengaged before he could reverse the hold on me.”
From somewhere behind us came the Genoskwa’s furious roar and the crash of another column falling. Then another roar, pained, that grew deeper in register as the Genoskwa assumed Ursiel’s demonform again and rose up onto his hind legs, coming into sight of us. Doing so put his head damned near twenty feet off the ground, and though we were most of the way up the amphitheater stairs, Ursiel’s glowing eyes and the Genoskwa’s ruined and bloody eye sockets were level with my own. The demon-bear opened his jaws and roared in fury.
