The figure ahead was that of the black dator of the First Born, Thurid, whose undying enmity I had earned that time I laid him low with my bare hands in the courtyard of the Temple of Issus, and bound him with his own harness before the noble men and women who had but a moment before been extolling his prowess.
Like many of his fellows, he had apparently accepted the new order of things with good grace, and had sworn fealty to Xodar, his new ruler;but I knew that he hated me, and I was sure that in his heart he envied and hated Xodar, so I had kept a watch upon his comings and goings, to the end that of late I had become convinced that he was occupied with some manner of intrigue.
Several times I had observed him leaving the walled city of the First Born after dark, taking his way out into the cruel and horrible Valley Dor, where no honest business could lead any man.
Tonight he moved quickly along the edge of the forest until well beyond sight or sound of the city, then he turned across the crimson sward toward the shore of the Lost Sea of Korus.
The rays of the nearer moon, swinging low across the valley, touched his jewel-incrusted harness with a thousand changing lights and glanced from the glossy ebony of his smooth hide.Twice he turned his head back toward the forest, after the manner of one who is upon an evil errand, though he must have felt quite safe from pursuit.
I did not dare follow him there beneath the moonlight, since it best suited my plans not to interrupt his--I wished him to reach his destination unsuspecting, that I might learn just where that destination lay and the business that awaited the night prowler there.
So it was that I remained hidden until after Thurid had disappeared over the edge of the steep bank beside the sea a quarter of a mile away.Then, with Woola following, I hastened across the open after the black dator.
The quiet of the tomb lay upon the mysterious valley of death, crouching deep in its warm nest within the sunken area at the south pole of the dying planet.In the far distance the Golden Cliffs raised their mighty barrier faces far into the starlit heavens, the precious metals and scintillating jewels that composed them sparkling in the brilliant light of Mars's two gorgeous moons.
At my back was the forest, pruned and trimmed like the sward to parklike symmetry by the browsing of the ghoulish plant men.
Before me lay the Lost Sea of Korus, while farther on I caught the shimmering ribbon of Iss, the River of Mystery, where it wound out from beneath the Golden Cliffs to empty into Korus, to which for countless ages had been borne the deluded and unhappy Martians of the outer world upon the voluntary pilgrimage to this false heaven.
The plant men, with their blood-sucking hands, and the monstrous white apes that make Dor hideous by day, were hidden in their lairs for the night.
There was no longer a Holy Thern upon the balcony in the Golden Cliffs above the Iss to summon them with weird cry to the victims floating down to their maws upon the cold, broad bosom of ancient Iss.
The navies of Helium and the First Born had cleared the fortresses and the temples of the therns when they had refused to surrender and accept the new order of things that had swept their false religion from long-suffering Mars.
In a few isolated countries they still retained their age-old power; but Matai Shang, their hekkador, Father of Therns, had been driven from his temple.Strenuous had been our endeavors to capture him; but with a few of the faithful he had escaped, and was in hiding--where we knew not.
As I came cautiously to the edge of the low cliff overlooking the Lost Sea of Korus I saw Thurid pushing out upon the bosom of the shimmering water in a small skiff--one of those strangely wrought craft of unthinkable age which the Holy Therns, with their organization of priests and lesser therns, were wont to distribute along the banks of the Iss, that the long journey of their victims might be facilitated.
Drawn up on the beach below me were a score of similar boats, each with its long pole, at one end of which was a pike, at the other a paddle.Thurid was hugging the shore, and as he passed out of sight round a near-by promontory I shoved one of the boats into the water and, calling Woola into it, pushed out from shore.
The pursuit of Thurid carried me along the edge of the sea toward the mouth of the Iss.The farther moon lay close to the horizon, casting a dense shadow beneath the cliffs that fringed the water.Thuria, the nearer moon, had set, nor would it rise again for near four hours, so that I was ensured concealing darkness for that length of time at least.
On and on went the black warrior.Now he was opposite the mouth of the Iss.Without an instant's hesitation he turned up the grim river, paddling hard against the strong current.
After him came Woola and I, closer now, for the man was too intent upon forcing his craft up the river to have any eyes for what might be transpiring behind him.He hugged the shore where the current was less strong.
Presently he came to the dark cavernous portal in the face of the Golden Cliffs, through which the river poured.On into the Stygian darkness beyond he urged his craft.
It seemed hopeless to attempt to follow him here where I could not see my hand before my face, and I was almost on the point of giving up the pursuit and drifting back to the mouth of the river, there to await his return, when a sudden bend showed a faint luminosity ahead.
My quarry was plainly visible again, and in the increasing light from the phosphorescent rock that lay embedded in great patches in the roughly arched roof of the cavern I had no difficulty in following him.
It was my first trip upon the bosom of Iss, and the things I saw there will live forever in my memory.
