Owing to this partial protection, the hunter was able to reach the cavern without serious injury. The entrance was rather strait; and Raphtontis flew upon the Voormis with open beak and flapping wings, compelling them to withdraw into the interior while Ralibar Vooz made firm his position on the threshold-ledge. Some, however, threw themselves on their faces to allow the passage of Raphtontis; and, rising when the bird had gone by, they assailed the Commorian as he followed his guide into the fetid gloom. They stood only half erect, and their shaggy heads were about his thighs and hips, snarling and snapping like dogs; and they clawed him with hook-shaped nails that caught and held in the links of his chain-armor.

Weaponless he fought them in obedience to his geas, striking down their hideous faces with his mailed fists in a veritable madness that was not akin to the ardor of a huntsman. He felt their nails and teeth break on the close-woven links as he hurled them loose; but others took their place when he won onward a little into the murky cavern; and their females struck at his legs like darting serpents; and their young beslavered his ankles with mouths wherein the fangs were as yet ungrown.

Before him, for his guidance, he heard the clanking of the wings of Raphtontis, and the harsh cries, half hiss, half caw, that were emitted by this bird at intervals. The darkness stifled him with a thousand stenches; and his feet slipped in blood and filth at every step. But anon he knew that the Voormis had ceased to assail him. The cave sloped downward; and he breathed an air that was edged with sharp, acrid mineral odors.

Groping for awhile through sightless night and descending a steep incline, he came at length to a sort of underground hall in which neither day nor darkness prevailed. Here the archings of rock were visible by an obscure glow such as hidden moons might yield. Thence, through declivitous grottoes and along perilously skirted gulfs, he was conducted ever downward by Raphtontis into the world beneath the mountain Voormithadreth. Everywhere was that dim, unnatural light whose source he could not ascertain. Wings that were too broad for those of the bat flew vaguely overhead; and at whiles, in the shadowy caverns, he beheld great, fearsome bulks having a likeness to those behemoths and giant reptiles which burdened the Earth in earlier times, but because of the dimness he could not tell if these were living shapes or forms that the stone had taken.

Strong was the compulsion of his geas on Ralibar Vooz; and a numbness had seized his mind; and he felt only a dulled fear and a dazed wonder. It seemed that his will and his thoughts were no longer his own, but were become those of some alien person. He was going down to some obscure but predestined end, by a route that was darksome but foreknown.

At last the bird Raphtontis paused and hovered significantly in a cave distinguished from the others by a most evil potpourri of smells. Ralibar Vooz deemed at first that the cave was empty. Going forward to join Raphtontis, he stumbled over certain attenuated remnants on the floor, which appeared to be the skin-clad skeletons of men and various animals. Then, following the coal-bright gaze of the demon bird, he discerned in a dark recess the formless bulking of a couchant mass. And the mass stirred a little at his approach, and put forth with infinite slothfulness a huge and toad-shaped head. And the head opened its eyes very slightly, as if half-awakened from slumber, so that they were visible as two slits of oozing phosphor in the black, browless face.

Ralibar Vooz perceived an odor of fresh blood amid the many fetors that rose to besiege his nostrils. A horror came upon him therewith; for, looking down, he beheld lying before the shadowy monster the lean husk of a thing that was neither man, beast, nor Voormi. He stood hesitant, fearing to go closer yet powerless to retreat. But, admonished by an angry hissing from the archaeopterix, together with a slashing stroke of its beak between his shoulder-blades, he went forward till he could see the fine dark fur on the dormant body and sleepily porrected head.

With new horror, and a sense of hideous doom, he heard his own voice speaking without volition: “O Lord Tsathoggua, I am the blood-offering sent by the sorcerer Ezdagor.”

There was a sluggish inclination of the toad-like head; and the eyes opened a little wider, and light flowed from them in viscous tricklings on the creased under-lids. Then Ralibar Vooz seemed to hear a deep, rumbling sound; but he knew not whether it reverberated in the dusky air or in his own mind. And the sound shaped itself, albeit uncouthly, into syllables and words:

“Thanks are due to Ezdagor for this offering. But, since I have fed lately on a well-blooded sacrifice, my hunger is appeased for the present, and I require not the offering. However, it may be that others of the Old Ones are athirst or famished. And, since you came here with a geas upon you, it is not fitting that you should go hence without another. So I place you under this geas, to betake yourself downward through the caverns till you reach, after long descent, that bottomless gulf over which the spider-god Atlach-Nacha weaves his eternal webs. And there, calling to Atlach-Nacha, you must say: ‘I am the gift sent by Tsathoggua.’”

So, with Raphtontis leading him, Ralibar Vooz departed from the presence of Tsathoggua by another route than that which had brought him there. The way steepened more and more; and it ran through chambers that were too vast for the searching of sight; and along precipices that fell sheer for an unknown distance to the black, sluggish foam and somnolent murmur of underworld seas.

At last, on the verge of a chasm whose farther shore was lost in darkness, the night-flying bird hung motionless with level wings and down-dropping tail. Ralibar Vooz went close to the verge and saw that great webs were attached to it at intervals, seeming to span the gulf with their multiple crossing and reticulations of grey, rope-thick strands. Apart from these, the chasm was bridgeless. Far out on one of the webs he discerned a darksome form, big as a crouching man but with long spider-like members. Then, like a dreamer who hears some nightmare sound, he heard his own voice crying loudly: “O Atlach-Nacha, I am the gift sent by Tsathoggua.”

The dark form ran toward him with incredible swiftness. When it came near he saw that there was a kind of face on the squat ebon body, low down amid the several-jointed legs. The face peered up with a weird expression of doubt and inquiry; and terror crawled through the veins of the bold huntsman as he met the small, crafty eyes that were circled about with hair.

Thin, shrill, piercing as a sting, there spoke to him the voice of the spider-god Atlach-Nacha: “I am duly grateful for the gift. But, since there is no one else to bridge this chasm, and since eternity is required for the task, I cannot spend my time in extracting you from those curious shards of metal. However, it may be that the antehuman sorcerer Haon-Dor, who abides beyond the gulf in his palace of primal enchantments, can somehow find a use for you. The bridge I have just now completed runs to the threshold of his abode; and your weight will serve to test the strength of my weaving. Go then, with this geas upon you, to cross the bridge and present yourself before Haon-Dor, saying: ‘Atlach-Nacha has sent me.’”

With these words, the spider-god withdrew his bulk from the web and ran quickly from sight along the chasm-edge, doubtless to begin the construction of a new bridge at some remoter point.

Though the third geas was heavy and compulsive upon him, Ralibar Vooz followed Raphtontis none too willingly over the night-bound depths. The weaving of Atlach-Nacha was strong beneath his feet, giving and swaying only a little; but between the strands, in unfathomable space below, he seemed to descry the dim flitting of dragons with claw-tipped wings; and, like a seething of the darkness, fearful hulks without name appeared to heave and sink from moment to moment.
