Toshmere approached Demarzule in his headquarters as the word came. "There is not much time left, Hetrarra. The repository is ready."

Demarzule looked out upon the sprawling works and great machines so pitifully huddled together on an alien planet. This was all that remained of the vast empire which he had dreamed of extending to the limits of space itself, the empire over which he was to have been supreme Hetrarra. And in a short moment this remnant would be wiped out under the devastating supremacy of the now mightier Dragbora.

He looked at Toshmere hesitantly. In the face of certain death the old, lean, sinewy scientist showed nothing but calm. The Hetrarra took one final glance at the remnants of his Sirenian Empire and nodded.

"I am ready," he said.

They went out to the entrance to the shaft leading toward the heart of the planet. The shaft had been built with the knowledge of only a few Sirenians and none of them were aware of its purpose, thinking rather that it was a means of defense.

Nobody saw the Hetrarra and the genius Toshmere enter the elevator that carried them forever into the depths below the surface of the planet.

Underwood and Illia came to the end of the page and Underwood swore softly as he thumbed through the few remaining sheets. There was no more about the ancient Demarzule and Toshmere.

The writer of the history had apparently been one of the Sirenian scientists, a confidant and friend of Toshmere who had been close to him in those last days. He had been one of the few to witness the descent of the two into the depths of the planet, but he knew nothing of what happened when they reached the bottom and sealed the repository.

He did not know which one had survived in that mighty struggle that must have taken place below.

And shortly no one of the Sirenians cared what the fate of their deserting Hetrarra might have been, for the great Dragboran fleet was upon them. With the mighty, unknown weapon that struck terror to the mightiest of Sirenia, they sped out of space and swiftly nullified the Sirenian defenses. It was a carnage that was frightful even to the Sirenians, so schooled in the methods of shedding blood. Their defenses might not have existed for all the effect they had on their enemy. At first one by one, and then by tens, the operators were touched by death and their machines turned to molten ruin.
