And then a sound rocked the vaults, a deep, hollow booming, like the blow of a monster fist, and the shock of it shivered in the very walls. Ingold paused in his stride, his eyes narrowing to a burning glitter of concentration as he listened; then he was striding down the corridor, Rudy following behind with drawn sword. As they turned the corner, Rudy saw the wizard shift the torch in his hands, and the rough wood seemed to elongate into a six-foot staff, the fire at its tip swelling and whitening to the diamond brilliance of a magnesium torch, searing like a crystal vibration into every crack of those stained and ancient walls. Holding the blazing staff half like a lamp, half like a weapon, the wizard moved ahead of him, shabby cloak billowing in his wake like wings. Rudy hurried after, the darkness falling back all around them and closing in behind.
Somewhere very close to them, a second blow resounded, shaking the stone under their feet like the smash of a piston driven by an insanely giant machine. Cold and hollow with hunger and fatigue, Rudy wondered shakily if they'd be killed, but the thought of it was strangely impersonal. Corridors converged, widening the darkness where they trod; he could now smell water and mold, and all around them the stone-acid stink of the dark. Somewhere, all that was left of the mob who had taken refuge in Alwir's villa-the handful of Guards and the scarlet Church troops, the fat man with his garden rake and the young woman with her attendant mob of children, and all the other faces that had swum in the glaring maelstrom above-stairs-were cowering in the dark, jumping shadows of the vaults, watching with horrified eyes the might of the Dark Ones hammering the barred iron doors, the only line of defense, from their massive hinges.
The might of the Dark! Rudy felt it, like a blow in the face, as the third explosion rocked the foundations of the villa; he felt the contraction of the air, and the evil intelligence watching them as they passed. The winds had begun to whip through the passageways like the rising forerunners of a gale, fluttering in Ingold's mantle and twisting at his own long hair. The light from the staff in the wizard's hand broadened to a blaze like hot noon, scorching out the secrets of the darkness, and in its blinding glare they turned a corner into a major thoroughfare and saw through the heavy shadows that blotted the air like smoke the great doors that lay at the end.
Though Rudy could see no single form, no shape in the darkness, he sensed the malevolence that beat the air with the movement of a thousand threshing wings. Their power seemed to stretch across the corridor like a wall; beyond it, barely visible in the clotted shadows, he could see the broad line of torchlight under the barred doors. There were no sounds from the people behind those doors. Those who had made it to that last covert in the vaults faced the Dark in silence.
He felt the change in the Dark, the sudden surge of that terrible alien power, and the thunder of that explosive sound roared in his ears as he saw the doors buckle and collapse, breaking inward in a flying hurricane of splintering wood. Sickly failing torchlight showed him faces beyond the broken doors and silhouetted smoky forms taking sudden shape in the darkness.
Into that darkness Ingold flung himself without so much as breaking stride, the cold light hurling around him like the explosion of a bursting star. Rudy followed, clinging to the light as to a mantle, and for one brief, terrible instant it seemed that the darkness streamed back on them, covering and smothering that brilliant burning light.
Whether it was exhaustion playing tricks on his mind or some magic of the Dark, Rudy did not know. He did not think he had shifted or closed his eyes and knew he hadn't looked away. But for one instant, there was the darkness, pouring down over the light. And the next moment, there was only light, white and chill, surrounding the strong, shabby form of the old man who stalked down that empty corridor. Streaming through the broken doors, the white light fell on waxy, pinched faces, was reflected from terrified eyes, and edged the steel in the hands of the thin line of troops stretched between the packed mob of surviving refugees and the doors. Then the light faded, shrinking naturally from the blinding glow to the yellow splotch of simple torch flame.
Rudy knew that the Dark were gone. He sensed it in some way he could not be sure of. There were none in the vaults, none left in the villa over their heads. Following Ingold down toward the doors, their footfalls echoing hollowly in the empty shadows of the corridor, he could feel the emptiness stretching around and behind him into the darkness. Whether the Dark had drawn off before the wizard's wrath or simply faded away, sated with their night's kill, he didn't know. In a way it didn't matter. All that mattered was that they were gone. He was safe. He had survived the night.
