I am,” she answered. “For fifteen years a slave in this terrible place, and now that they have tired of me and become fearful of the power which my knowledge of their ways has given me I am but recently condemned to die the death.”
She shuddered.
“What death?” I asked.
“The Holy Therns eat human flesh,” she answered me; “but only that which has died beneath the sucking lips of a plant man—flesh from which the defiling blood of life has been drawn. And to this cruel end I have been condemned. It was to be within a few hours, had your advent not caused an interruption of their plans.”
“Was it then Holy Therns who felt the weight of John Carter’s hand?” I asked.
“Oh, no; those whom you laid low are lesser therns; but of the same cruel and hateful race. The Holy Therns abide upon the outer slopes of these grim hills, facing the broad world from which they harvest their victims and their spoils.
“Labyrinthine passages connect these caves with the luxurious palaces of the Holy Therns, and through them pass upon their many duties the lesser therns, and hordes of slaves, and prisoners, and fierce beasts; the grim inhabitants of this sunless world.
“There be within this vast network of winding passages and countless chambers men, women, and beasts who, born within its dim and gruesome underworld, have never seen the light of day—nor ever shall.
“They are kept to do the bidding of the race of therns; to furnish at once their sport and their sustenance.
“Now and again some hapless pilgrim, drifting out upon the silent sea from the cold Iss, escapes the plant men and the great white apes that guard the Temple of Issus and falls into the remorseless clutches of the therns; or, as was my misfortune, is coveted by the Holy Thern who chances to be upon watch in the balcony above the river where it issues from the bowels of the mountains through the cliffs of gold to empty into the Lost Sea of Korus.
“All who reach the Valley Dor are, by custom, the rightful prey of the plant men and the apes, while their arms and ornaments become the portion of the therns; but if one escapes the terrible denizens of the valley for even a few hours the therns may claim such a one as their own. And again the Holy Thern on watch, should he see a victim he covets, often tramples upon the rights of the unreasoning brutes of the valley and takes his prize by foul means if he cannot gain it by fair.
“It is said that occasionally some deluded victim of Barsoomian superstition will so far escape the clutches of the countless enemies that beset his path from the moment that he emerges from the subterranean passage through which the Iss flows for a thousand miles before it enters the Valley Dor as to reach the very walls of the Temple of Issus; but what fate awaits one there not even the Holy Therns may guess, for who has passed within those gilded walls never has returned to unfold the mysteries they have held since the beginning of time.
“The Temple of Issus is to the therns what the Valley Dor is imagined by the peoples of the outer world to be to them; it is the ultimate haven of peace, refuge, and happiness to which they pass after this life and wherein an eternity of eternities is spent amidst the delights of the flesh which appeal most strongly to this race of mental giants and moral pygmies.”
“The Temple of Issus is, I take it, a heaven within a heaven,” I said. “Let us hope that there it will be meted to the therns as they have meted it here unto others.”
Even if they escaped the Valley Dor, they would be punished by their own people for blasphemy. Nevertheless, John persuaded his companions to follow him. They freed other slaves and gave them weapons.
We had proceeded for possibly an hour without serious interruption, and Thuvia had just whispered to me that we were approaching our first destination, when on entering a great chamber we came upon a man, evidently a thern.
He wore in addition to his leathern trappings and jewelled ornaments a great circlet of gold about his brow in the exact centre of which was set an immense stone, the exact counterpart of that which I had seen upon the breast of the little old man at the atmosphere plant nearly twenty years before.
It is the one priceless jewel of Barsoom. Only two are known to exist, and these were worn as the insignia of their rank and position by the two old men in whose charge was placed the operation of the great engines which pump the artificial atmosphere to all parts of Mars from the huge atmosphere plant, the secret to whose mighty portals placed in my possession the ability to save from immediate extinction the life of a whole world.
The stone worn by the thern who confronted us was of about the same size as that which I had seen before; an inch in diameter I should say. It scintillated nine different and distinct rays; the seven primary colours of our earthly prism and the two rays which are unknown upon Earth, but whose wondrous beauty is indescribable.
As the thern saw us his eyes narrowed to two nasty slits.
“Stop!” he cried. “What means this, Thuvia?”
For answer the girl raised her revolver and fired pointblank at him. Without a sound he sank to the earth, dead.
“Beast!” she hissed. “After all these years I am at last revenged.”
Then as she turned toward me, evidently with a word of explanation on her lips, her eyes suddenly widened as they rested upon me, and with a little exclamation she started toward me.
“O Prince,” she cried, “Fate is indeed kind to us. The way is still difficult, but through this vile thing upon the floor we may yet win to the outer world. Notest thou not the remarkable resemblance between this Holy Thern and thyself?”
The man was indeed of my precise stature, nor were his eyes and features unlike mine; but his hair was a mass of flowing yellow locks, like those of the two I had killed, while mine is black and close cropped.
“What of the resemblance?” I asked the girl Thuvia. “Do you wish me with my black, short hair to pose as a yellow-haired priest of this infernal cult?”
She smiled, and for answer approached the body of the man she had slain, and kneeling beside it removed the circlet of gold from the forehead, and then to my utter amazement lifted the entire scalp bodily from the corpse’s head.
Rising, she advanced to my side and placing the yellow wig over my black hair, crowned me with the golden circlet set with the magnificent gem.
“Now don his harness, Prince,” she said, “and you may pass where you will in the realms of the therns, for Sator Throg was a Holy Thern of the Tenth Cycle, and mighty among his kind.”
As I stooped[9] to the dead man to do her bidding I noted that not a hair grew upon his head, which was quite as bald as an egg.
“They are all thus from birth,” explained Thuvia noting my surprise. “The race from which they sprang were crowned with a luxuriant growth of golden hair, but for many ages the present race has been entirely bald. The wig, however, has come to be a part of their apparel, and so important a part do they consider it that it is cause for the deepest disgrace were a thern to appear in public without it.”
In another moment I stood garbed in the habiliments[10] of a Holy Thern.
At Thuvia’s suggestion two of the released prisoners bore the body of the dead thern upon their shoulders with us as we continued our journey toward the storeroom, which we reached without further mishap.
Here the keys which Thuvia bore from the dead thern of the prison vault were the means of giving us immediate entrance to the chamber, and very quickly we were thoroughly outfitted with arms and ammunition.
By this time I was so thoroughly fagged out that I could go no further, so I threw myself upon the floor, bidding Tars Tarkas to do likewise, and cautioning two of the released prisoners to keep careful watch.
In an instant I was asleep.
