Water filled the halls from top to bottom, thick and black as the bottom of the sea, choking off breath. He made it air again, unknowingly, and ran on, and suddenly the air gained weight until it seemed every inch of his skin supported a mountain, squeezing in from all directions. In the instant before he was crushed to nothingness he chose tides out of the flood of Power raging through him—he did not know how or which or why; it was too fast for thought or knowing—and the pressure vanished. He pursued Ba’alzamon, and the very air was abruptly solid rock encasing him, then molten stone, then nothing at all to fill his lungs. The ground beneath his boots pulled at him as if every pound suddenly weighed a thousand, then all weight vanished so that a step left him spinning in midair. Unseen maws gaped to rip his mind from his body, to tear away his soul. He sprang each trap and ran on; what Ba’alzamon twisted to destroy him, he made right without being aware of how. Vaguely he knew that in some way he had brought things back into natural balance, forced them into line with his own dance down that impossibly thin divide between existence and nothingness, but that knowledge was distant. All his awareness lay in the pursuit, the hunt, the death that must end it.

And then he was in the Heart of the Stone again, stalking through the rubbled gap that had been a wall. Some of the columns hung like broken teeth, now. And Ba’alzamon backed away from him, eyes burning, shadow cloaking him. Black lines like steel wires seemed to run off from Ba’alzamon into the darkness mounding around him, vanishing into unimaginable heights and distances within that blackness.

“I will not be undone!” Ba’alzamon cried. His mouth was fire; his shriek echoed among the columns. “I cannot be defeated! Aid me!” Some of the darkness shrouding him drifted into his hands, formed into a ball so black it seemed to soak up even the light of Callandor. Sudden triumph blazed in the flames of his eyes.

“You are destroyed!” Rand shouted. Callandor spun in his hands. Its light roiled the darkness, severed the steel-black lines around Ba’alzamon, and Ba’alzamon convulsed. As if there were two of him he seemed to dwindle and grow larger at the same time. “You are undone!” Rand plunged the shining blade into Ba’alzamon’s chest.

Ba’alzamon screamed, and the fires of his face flared wildly. “Fool!” he howled. “The Great Lord of the Dark can never be defeated!”

Rand pulled Callandor’s blade free as Ba’alzamon’s body sagged and began to fall, the shadow around him vanishing.
