It seemed that they traversed an enormous distance, among the more ancient vaults. Here the formation of the stone was softer and more friable, and the earthquake had wrought considerable damage. The floor was littered with detritus, the sides and roof were full of fractures, and some of the chambers had partially fallen in, so that their vacancy was revealed to the casual peering of Yanur and his companions.

Nearing the hall’s end, they were confronted by a chasm, dividing both floor and roof, and splitting the sill and lintel of the last chamber. The gulf was about four feet wide, and the torch of Yanur could not disclose its bottom. He found the name of Tnepreez on the lintel, whose antique inscription, telling the deeds and titles of the king, had been sundered in twain by the cataclysm. Then, walking on a narrow ledge, he entered the vault. Grotara and Thirlain Ludoch crowded behind him, leaving the sarcophagus in the hall.

The sepulchral throne of Tnepreez, overturned and broken, was lying across the fissure that had rifted the whole tomb from side to side. There was no trace of the mummy, which, from the chair’s inverted position, had doubtless fallen into those yawning depths in the hour of its overthrow.

Before the seekers could voice their disappointment and their dismay, the silence about them was broken by a dull rumbling as of distant thunder. The stone trembled beneath their feet, the walls shook and wavered, and the rumbling noise, in long, shuddering undulations, grew louder and more ominous. The solid floor appeared to rise and flow with a continuous, sickening motion; and then, as they turned to flee, it seemed that the universe came down upon them in a roaring deluge of night and ruin.

Grotara, wakening in darkness, was aware of an agonizing burden, as if some monumental shaft were builded on his crushed feet and lower legs. His head throbbed and ached as if from the stroke of a stunning mace. He found that his arms and body were free; but the pain in his extremities became insufferable, causing him to swoon anew, when he tried to drag them from beneath their incumbrance.

Terror closed upon him like the clutch of ghoulish fingers, as he realized his situation. An earthquake, such as had caused the abandonment of Chaon Gacca, had occurred; and he and his fellows were entombed in the catacombs. He called aloud, repeating the names of Yanur and Thirlain Ludoch many times; but there was no groan nor rustle to assure him that they still lived.

Reaching out with his right hand, he encountered numerous pieces of rubble. Slewing himself toward them, he found several boulder-sized fragments of stone, and among them a smooth and roundish thing, with a sharp ridge in the center, which he knew for the crested helmet worn by one of his companions. Even with the most painful striving, he could reach no further, and was unable to identify the owner. The metal was heavily dented, and the comb was bent as if by the impact of some ponderous mass.

In spite of his predicament, the fierce nature of Grotara refused to yield itself to despair. He drew himself to a sitting position, and, doubling forward, he contrived to reach the enormous block that had fallen across his nether limbs. He pushed against it with herculean effort, raging like a trapped lion, but the mass was immovable. For hours, it seemed, he strove as if with some monstrous cacodemon. His frenzy was calmed only by exhaustion. He lay back at length; and the darkness weighed upon him like a live thing, and seemed to gnaw him with fangs of pain and horror.

Delirium hovered near, and he thought that he heard a dim and hideous humming, far below in the stony bowels of the earth. The noise grew louder, as if ascending from a riven hell. He became aware of a wan, unreal light that wavered above him, disclosing in doubtful glimpses the shattered roof. The light strengthened; and lifting himself a little, he saw that it poured from the earthquake chasm in the floor.

It was a light such as he had never seen: a livid luster, that was not the reflection of lamp or torch or firebrand. Somehow, as if the senses of hearing and sight were confused, he identified it with the hideous humming.

Like a sourceless dawn, the luminosity crept upon the ruin wrought by the temblor. Grotara saw that the whole entrance of the tomb, and much of its concameration, had caved in. A fragment, striking him on the head, had knocked him senseless; and a huge section of the roof had fallen across his extremities.

The bodies of Thirlain Ludoch and Yanur were lying close to the broadened chasm. Both, he felt sure, were dead. The grizzled beard of Thirlain Ludoch was dark and stiff with blood that had run down from the crushed cranium; and Yanur was half-buried in a pile of blocks and detritus, from which his torso and left arm were emergent. His torch had burned itself out in his stiffly clutching fingers, as if in a blackened socket.

All this Grotara noted in a vague dream-like manner. Then he perceived the real source of the strange illumination. A coldly shining, hueless globe, round as a puffball and large as a human head, had risen from the fissure and was hovering above it like a mimic moon. The thing oscillated with a slight but ceaseless vibratory motion. From it, as if caused by this vibration, the heavy humming poured, and the light fell in ever-trembling waves.

A dim awe was upon Grotara; but he felt no terror. It seemed that the light and sound were woven upon his senses like some Lethean spell. Rigid he sat, forgetful of his pain and despair, while the globe hovered for a few instants above the chasm, and then floated slowly and horizontally, till it hung directly over the upturned features of Yanur.

With the same deliberate slowness, the same ceaseless oscillation, it descended upon the face and neck of the dead man, which appeared to melt away like tallow as the globe settled lower and lower. The humming deepened, the globe flamed with an eerier luster, and its death-like pallor was mottled with impure iris. It swelled and bloated obscenely, while the whole head of the warrior shrank within the helmet, and the plates of his cuirass fell in as if the very torso were shrivelling beneath them.

Grotara’s eyes beheld the horrific vision clearly; but his brain was numbed as if by a merciful hemlock. It was hard to remember, hard to think... but somehow he recalled the empty tombs, the ownerless crowns and vestments. The enigma of the missing mummies, over which he and his companions had puzzled vainly, was now resolved. But the thing that battened upon Yanur was beyond all mortal knowledge or surmise. It was some ghoulish denizen of a nether world, set free by the demons of earthquake.

Now, in the catalepsy that thralled him, he saw the gradual settling of the piled debris in which the legs and hips of Yanur were inhumed. The helmet and body-mail were like empty shards, the outflung arm had withered, had shortened, and the very bones were dwindling away, appearing to melt and liquefy. The globe had grown enormous. It was flushed with unclean ruby, like a vampire moon. From it, there issued palpable ropes and filaments, pearly, shuddering into strange colors, that appeared to fasten themselves to the ruined floor and walls and roof, like the weaving of a spider. Thickly and more thickly they multiplied, forming a curtain between Grotara and the chasm, and falling upon Thirlain Ludoch and himself, till he saw the sanguine burning of the globe as through arabesques of baleful opal.

Now the web had filled the entire tomb. It ran and glistened with a hundred changing hues, it dripped with glories drawn from the spectrum of dissolution. It bloomed with ghostly blossoms, and foliages that grew and faded as if by necromancy. The eyes of Grotara were blinded; more and more he was meshed in the weird web. Unearthly, chill as the fingers of death, its gossamers clung and quivered upon his face and hands.
