who had reigned in Kuthchemes three thousand years ago, when the kingdoms of Stygia stretched far northward of the great river, over the meadows of Shem, and into the uplands. Then the great drift of the Hyborians swept southward from the cradle-land of their race near the northern pole. It was a titanic drift, extending over centuries and ages. But in the reign of Thugra Khotan, the last magician of Kuthchemes, gray-eyed, tawny-haired barbarians in wolfskins and scale-mail had ridden from the north into the rich uplands to carve out the kingdom of Koth with their iron swords. They had stormed over Kuthchemes like a tidal wave, washing the marble towers in blood, and the northern Stygian kingdom had gone down in fire and ruin.
But while they were shattering the streets of his city and cutting down his archers like ripe corn, Thugra Khotan had swallowed a strange terrible poison, and his masked priests had locked him into the tomb he himself had prepared. His devotees died about that tomb in a crimson holocaust, but the barbarians could not burst the door, nor even mar the structure by maul or fire. So they rode away, leaving the great city in ruins, and in his ivory-domed sepulcher great Thugra Khotan slept unmolested, while the lizards of desolation gnawed at the crumbling pillars, and the very river that watered his land in old times sank into the sands and ran dry.
Many a thief sought to gain the treasure which fables said lay heaped about the moldering bones inside the dome. And many a thief died at the door of the tomb, and many another was harried by monstrous dreams to die at last with the froth of madness on his lips.
So Shevatas shuddered as he faced the tomb, nor was his shudder altogether occasioned by the legend of the serpent said to guard the sorcerer’s bones. Over all myths of Thugra Khotan hung horror and death like a pall. From where the thief stood he could see the ruins of the great hall wherein chained captives had knelt by the hundreds during festivals to have their heads hacked off by the priest-king in honor of Set, the Serpent-god of Stygia. Somewhere near by had been the pit, dark and awful, wherein screaming victims were fed to a nameless amorphic monstrosity which came up out of a deeper, more hellish cavern. Legend made Thugra Khotan more than human; his worship yet lingered in a mongrel degraded cult, whose votaries stamped his likeness on coins to pay the way of their dead over the great river of darkness of which the Styx was but the material shadow. Shevatas had seen this likeness, on coins stolen from under the tongues of the dead, and its image was etched indelibly in his brain.
But he put aside his fears and mounted to the bronze door, whose smooth surface offered no bolt or catch. Not for naught had he gained access into darksome cults, had harkened to the grisly whispers of the votaries of Skelos under midnight trees, and read the forbidden iron-bound books of Vathelos the Blind.
Kneeling before the portal, he searched the sill with nimble fingers; their sensitive tips found projections too small for the eye to detect, or for less-skilled fingers to discover. These he pressed carefully and according to a peculiar system, muttering a long-forgotten incantation as he did so. As he pressed the last projection, he sprang up with frantic haste and struck the exact center of the door a quick sharp blow with his open hand.
There was no rasp of spring or hinge, but the door retreated inward, and the breath hissed explosively from Shevatas’ clenched teeth. A short narrow corridor was disclosed. Down this the door had slid, and was now in place at the other end. The floor, ceiling and sides of the tunnel-like aperture were of ivory, and now from an opening on one side came a silent writhing horror that reared up and glared on the intruder with awful luminous eyes; a serpent twenty feet long, with shimmering, iridescent scales.
The thief did not waste time in conjecturing what night-black
