"Now we are ready for their attack," he said to Turgan. "You are as familiar with these weapons as I am, but I will instruct a dozen of [109] your followers in using them. It is possible that we may not be able to operate the weapons ourselves."

"I can operate one weapon while you manipulate the other, Damis," replied the Kildare. "However, no harm will be done in instructing others."

"I may not be here," said Damis briefly.

Without replying to the questions of Turgan and Toness, he proceeded to instruct a dozen of the Earthmen in the use of the terrible Martian weapons. When he was certain that he had a half dozen men capable of attending to each of the weapons, he turned to Turgan.

"I may not be here when the weapons are used," he said. "When I thought that Lura had gone to Venus, I gave her up and sacrificed both her and my heart on the altar of our cause, for it is what she would have chosen. Now I have accomplished the sacrifice and returned with the Martian weapons to find that she is a captive in the Viceroy's palace. We can turn on the rays and reduce the building and all in it to a pinch of dust in a few seconds, but Lura would be immolated with the Sons of God. The weapons are here; our men know how to use them, and my usefulness is at an end. Now I stand here with no more responsibility for our success than the humblest swordsman. Since I am no longer needed, I will leave the fate of the Earth to you and follow out my private designs."

"Where are you going, Nepthalim?" cried Toness. The question was echoed by all within the sound of his voice. Only Turgan smiled as though he knew Damis' answer.

"Where could I go, Akildare, but to one place?" replied the Nepthalim. "I go to Glavour's palace. I have two errands there. One is to rescue Lura and the other is to mete out to Glavour the death which I swore that I would accomplish. The rays can be turned on and the palace demolished at any time, but I ask that you wait until I return with Lura or until you know that we are dead."

"But if the Jovian fleet arrives before that time, Nepthalim?" demanded Toness.

"Then give the word for the use of the weapons, Akildare, and Lura's soul and mine will join the thousands of others whose lives are but a part of the price the race of Earthmen have had to pay to rid their planet of the Sons of God."

"It grieves me, Damis, to see you go to certain death," said Turgan sadly to the blond giant, "yet I will say nothing to stop you. Were it not that my presence would hinder you in your attempt, I would accompany you."
