"No slimy silian that haunts the depths of Korus is more at home in water than is Xodar," he replied.
"Good. The red one in all probability cannot swim," I said, "since there is scarce enough water in all their domains to float the tiniest craft. One of us therefore will have to support him through the sea to the craft we select. I had hoped that we might make the entire distance below the surface, but I fear that the red youth could not thus perform the trip. Even the bravest of the brave among them are terrorized at the mere thought of deep water, for it has been ages since their forebears saw a lake, a river or a sea."
"The red one is to accompany us?" asked Xodar.
"Yes."
"It is well. Three swords are better than two. Especially when the third is as mighty as this fellow's. I have seen him battle in the arena at the rites of Issus many times. Never, until I saw you fight, had I seen one who seemed unconquerable even in the face of great odds. One might think you two master and pupil, or father and son. Come to recall his face there is a resemblance between you. It is very marked when you fight—there is the same grim smile, the same maddening contempt for your adversary apparent in every movement of your bodies and in every changing expression of your faces."
"Be that as it may, Xodar, he is a great fighter. I think that we will make a trio difficult to overcome, and if my friend Tars Tarkas, Jeddak of Thark, were but one of us we could fight our way from one end of Barsoom to the other even though the whole world were pitted against us."
"It will be," said Xodar, "when they find from whence you have come. That is but one of the superstitions which Issus has foisted upon a credulous humanity. She works through the Holy Therns who are as ignorant of her real self as are the Barsoomians of the outer world. Her decrees are borne to the therns written in blood upon a strange parchment. The poor deluded fools think that they are receiving the revelations of a goddess through some supernatural agency, since they find these messages upon their guarded altars to which none could have access without detection. I myself have borne these messages for Issus for many years. There is a long tunnel from the temple of Issus to the principal temple of Matai Shang. It was dug ages ago by the slaves of the First Born in such utter secrecy that no thern ever guessed its existence.
"The therns for their part have temples dotted about the entire civilized world. Here priests whom the people never see communicate the doctrine of the Mysterious River Iss, the Valley Dor, and the Lost Sea of Korus to persuade the poor deluded creatures to take the voluntary pilgrimage that swells the wealth of the Holy Therns and adds to the numbers of their slaves.
"Thus the therns are used as the principal means for collecting the wealth and labour that the First Born wrest from them as they need it. Occasionally the First Born themselves make raids upon the outer world. It is then that they capture many females of the royal houses of the red men, and take the newest in battleships and the trained artisans who build them, that they may copy what they cannot create.
"We are a non-productive race, priding ourselves upon our non-productiveness. It is criminal for a First Born to labour or invent. That is the work of the lower orders, who live merely that the First Born may enjoy long lives of luxury and idleness. With us fighting is all that counts; were it not for that there would be more of the First Born than all the creatures of Barsoom could support, for in so far as I know none of us ever dies a natural death. Our females would live for ever but for the fact that we tire of them and remove them to make place for others. Issus alone of all is protected against death. She has lived for countless ages."
