And, too, Tony saw the carbon-pistol lying on the stones near by.

“Jimmy!” His voice was a cracked wheeze. “Gun—pyramid—”

Into Desquer’s eyes sprang murder-light. The fingers contracted, sending agony down Tony’s spine. Jimmy understood, though, and dived for the pistol. He snatched it up, leveled it at the pyramid and the oncoming priests.

Desquer yelled like a beast. His fingers relaxed. Somehow he writhed free, sprang up, plunged toward Jimmy.

“Don’t!” he bellowed. “Don’t—”

From the gun’s muzzle burst a raving blast of searing flame. The incredible pressure that had made the Earth Star was released. Straight through the ranks of the priests it bored an aisle, into the heart of the pyramid, melting and wrecking solid stone with the terrific power of its thrust. The volcanic fires of Earth itself seemed to be latent in that—bullet!

Over the cries of the priests came a rumbling, crashing thunder. A block fell, clattering down the pyramid’s side. The structure buckled. Its whole side was torn out. The summit toppled and came thundering down, amid clouds of smoking dust and ruin.

Tony staggered erect, staring up. Something was happening to the cavern roof. The pyramid had been a pillar, supporting it. And now the support was gone—

Rocks fell from above. Cracks ran out like a great spider web. Something silvery flashed down from above, glinting red in the crimson glow. Tony remembered that above Alu was—the Midnight Sea!

And that sunless, tideless ocean was pouring into the cavern world through the crevasse that had been torn in its floor!
