And then with a cry she sent another lance of Hellfire at me, redoubled in strength.
Again, I caught it with a conjured cyclone infused with soulfire, though the effort was even more tremendous. Again I sent it spiraling up toward the ceiling—but this time I sent it all to one spot.
Even before the last of the Hellfire had smashed into the ceiling, I dropped to one knee, lifted my staff, and extended the strongest shield I could project, putting it between me and Ascher. It was a calculated bit of distraction on my part, giving her something she wasn’t psychologically equipped to ignore.
She screamed at me, her eyes furious, gathering more fire in her hands, seeing only a passive target, weakened and fallen to one knee, one she could smash to bits with a third and final strike—but I saw Lasciel’s glowing eyes widen in sudden dismay and understanding as the Fallen reached her own comprehension of consequences a few portions of a second too late to do any good.
An instant later, several hundred tons of molten and red-hot rock, chewed from the earth above us by Ascher’s own Hellfire-infused strike, came crashing down on top of her.
The noise was terrible. The destruction was appalling. Glowing hot stones bounced from my shield and then began to pile up against it, pushing at me and physically forcing me back across the ground. The pileup shoved me a good twenty feet across the amphitheater floor, with Michael hobbling frantically along a couple of feet ahead of me, crouching to take advantage of the protection of my shield.
After a few seconds, the falling stone became less violent and random, and I dropped my shield with a gasp of effort. I stayed right where I was, down on one knee, and bent forward at the waist, struggling to catch my breath, exhausted from the efforts of the past few moments. The vault was spinning around and around, too. When had it started doing that?
