On the top of the hill overlooking the palace grounds the two Martian weapons were placed on the ground, side by side. Damis carefully aligned the red rod on the Viceregal palace. When he had it set, with a word of warning, he closed the gravity anchor switch. The instrument settled a trifle on the solid rock on which it was bedded and then was motionless.

At a word from Damis, as many of the Terrestrials as could find a hand-rest pushed against it. It was as though they were pressing against the mountain itself. Damis sighted along the rod and adjusted it until it pointed at the center of the building.

"So much for that one," he said. "It is the less powerful of the two, but it will be enough to destroy the Sons of G.o.d and the Nepthalim who are in the palace. The few who are scattered over the Earth, we can dispose of at our leisure. If the Jovian fleet approaches the Earth from directly above us, we will be able to destroy it easily. In any event, this weapon is to be used only when it is approximately normal to the surface of the Earth. We must have it almost under the point from which the Jovians are approaching. That may be on the opposite side of the Earth."

"I think not, Nepthalim," said Toness. "We know that Glavour and Tubain have been in constant communication since the Jovian fleet pa.s.sed Mars and he expects them to land here. There would be no object in their taking a circuitous route, so they will probably drop directly down in the palace grounds."

"Let us hope so, Toness. In any event, we might as well anchor the weapon here as elsewhere."

He set the weapon with the blue rod on another patch of bare rock and tested the rod to make sure that it revolved freely and could be made to cover the entire heavens from horizon to horizon. He closed the gravity anchor switch and again the efforts of a dozen Terrestrials were futile to move it.

"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 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 G.o.d. 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 G.o.d."

"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."

"Your place, Kildare, is at the head of your men, whom you were born to rule. I can hope to succeed only by stealth, else a thousand men would come with me. Now call from the ranks one who is a barber that he may change the color of my hair and alter my face that I shall not be known."

At the Kildare's word, three men stepped forward from the ranks of swordsmen and announced themselves adepts in the art of disguise. Swift runners were sent to bring supplies and the three labored over Damis.

When they had finished their ministrations, only a close observer would have known him under the bushy black beard which covered his face.

CHAPTER VI

_In the Seraglio_

With a parting word to Turgan and his followers, Damis made his way alone down the hill and into the thick tropical jungle which grew up almost to the gates of the Viceregal palace. He was well acquainted with a secret entrance into the building. It was a matter of minutes for him to locate the outer end and open it.

For half a mile he made his way underground until a huge stone door barred his way. He felt for the hidden catches and the slab of rock rose before him. As he turned toward the doorway he found himself looking into the muzzle of a black ray tube in the hands of a gigantic Jovian in the uniform of the Viceroy's guards.

"Whence came you, Nepthalim?" demanded the guard, a cold note of suspicion in his voice.

"From far Torna," replied Damis readily. "I am Durmino, Komar of the province of Capries. The slaves rose on us and all were slain except me.

I have had to travel by night and hide by day to reach here. I knew not whether the slaves had conquered or not, but when I found them lying by thousands about Glavour's palace, I knew that the reign of the Sons of G.o.d was safe. What news from Tubain?"

The face of the Jovian guard cleared as Damis spoke. Durmino, a son of Glavour by one of his Terrestrial concubines, was Komar of Capries, a fact well known to Damis. There was nothing in the newcomer's story to excite suspicion.

"The fleet of the Ruler of the Universe is approaching," the guard replied. "In two hours it will be hovering above us. We would have needed no aid had not the dogs of Earthmen found our source of power and managed to destroy it with stolen ray tubes. We have been cooped up here like rats waiting for Tubain to arrive. When he comes our vengeance will be heavy."

"The heavier the better," growled Damis with an oath. "The dogs have been getting surly for a generation. I hope that Tubain will teach them a lesson that will not be forgotten for ages to come."

"He will, never fear," laughed the guard. "Already Glavour has made his plans. I am not a member of the council, yet I have heard enough to realize why Glavour is our ruler. My brain could not conceive of such a stupendous plan."

"I will go to my father now," said Damis. "What is the word for pa.s.sing the inner gate? I wish to surprise my sire for he doubtless mourns me as dead."

"He thinks you are dead," replied the guard, "yet I never heard of Glavour mourning for any loss which did not affect his pleasures. He has plenty of b.a.s.t.a.r.ds to take your place. The word is 'Tubain.'"

"I thank you, Son of G.o.d," said Damis, "and I will inform my sire of the great respect and high regard which you have for him. Fear not, your words shall be truthfully reported to him."

Leaving the Jovian guard hastily reviewing the conversation with the supposed Durmino, Damis made his way toward the palace. Since he knew that he would not reach another door until after several of the underground pa.s.sages with which the foundations of the palace were honeycombed had joined, he had little doubt of his ability to make his way unsuspected into the citadel. He debated for a moment on the advisability of killing the Jovian guard and taking his weapons, but caution prevailed, and empty-handed, save for a dagger concealed under his robes, he strode forward.

His knowledge of the pa.s.sword enabled him to pa.s.s the various guards he met without difficulty. There were many of the Nepthalim who held subordinate positions in the outlying provinces and who were seldom at court, and the Jovian guards, who in their hearts regarded the Nepthalim as little better than the Terrestrials, paid small attention to him. He pa.s.sed several guarded points before the path rose steeply and he pa.s.sed through the final gate into the palace itself. A Nepthalim pa.s.sed him hurriedly and Damis plucked at his robe.

"I am just from outpost," he said. "What news of Tubain?"

"The fleet has entered the atmosphere belt a thousand miles east of here," replied the Nepthalim. "They are dropping to an alt.i.tude of five miles and will then approach. They should arrive in an hour. It is well that they hurry."

"What rush is there?" asked Damis in surprise. "We may not be able to leave here, but, at the same time, all the forces the slaves can muster would never force an entrance."

"You have not heard then?" exclaimed the other in surprise.

"No--certainly not, if you have been on outpost--for I just learned it myself. There is a rumor that Havenner lied when he said that he killed Turgan, the Kildare and Damis, the renegade--the curse of Tubain rest on him--on Mars. It is said that they not only escaped death but have returned to Earth armed with the weapons of the red planet. Havenner is with Glavour now and no one knows what the outcome will be. Since Tubain is at hand, doubtless nothing will be done until he arrives. That is the reason why Tubain altered his course and came down so far away instead of directly overhead. He hopes thus to elude the Martian weapons if the Earthmen really have them."

"Surely that is a lie!" cried Damis.

"We hope that it is, yet Havenner would have been slain without mercy had he admitted that he left Mars without slaying or capturing Turgan and Damis. Many believe that it is true."

"Is Glavour in the council room?" asked Damis. "I have a message."

"It would be better for you to defer the message if it be ill news until Tubain arrives, brother, for Glavour is enraged beyond measure at all of us. He threatens to sacrifice us at the next games and he may do so unless Tubain alters the decree. He has not loved us since Damis broke his arm a month ago."

"Nevertheless, I will deliver my message," replied Damis. "While it may not please him, it is essential that he get it before Tubain arrives."
