“Behold, O Evagh,” said the voice. “I have preserved thee from the doom of thy fellow-men, and have made thee as they that inhabit the bourn of coldness, and they that inhale the airless void. Wisdom ineffable shall be thine, and mastery beyond the conquest of mortals, if thou wilt but worship me and become my thrall. With me thou shalt voyage amid the kingdoms of the north, and shalt pass among the green southern islands, and see the white falling of death upon them in the light from Yikilth. Our coming shall bring eternal frost on their gardens, and shall set upon their people’s flesh the seal of that gulf whose rigor paleth one by one the most ardent stars, and putteth rime at the core of suns. All this thou shalt witness, being as one of the lords of death, supernal and immortal; and in the end thou shalt return with me to that world beyond the uttermost pole, in which is mine abiding empire. For I am he whose coming even the gods may not oppose.”

Now, seeing that he was without choice in the matter, Evagh professed himself willing to yield worship and service to the pale worm. Beneath the instruction of Dooni and Ux Loddhan, he performed the sevenfold rite that is scarce suitable for narration here, and swore the threefold vow of unspeakable alienation.

Thereafter, for many days and nights, he sailed with Rlim Shaikorth a-down the coast of Mhu Thulan. Strange was the manner of that voyaging, for it seemed that the great ice-berg was guided by the sorcery of the worm, prevailing ever against wind and tide. And always, by night or day, like the beams of a deathly beacon, the chill splendor smote afar from Yikilth. Proud galleys were overtaken as they fled southward, and their crews were blasted at the oars; and often ships were caught and embedded in the new bastions of ice that formed daily around the base of that ever-growing mountain.

The fair Hyperborean ports, busy with maritime traffic, were stilled by the passing of Rlim Shaikorth. Idle were their streets and wharves, idle was the shipping in their harbors, when the pale light had come and gone. Far inland fell the rays, bringing to the fields and gardens a blight of trans-Arctic winter; and forests were frozen, and the beasts that roamed them were turned as if into marble, so that men who came long afterwards to that region found the elk and bear and mammoth still standing in all the postures of life. But, dwelling upon Yikilth, the sorcerer Evagh was immune to the icy death; and, sitting in his house or walking abroad on the berg, he was aware of no sharper cold than that which abides in summer shadows.

Now, beside Dooni and Ux Loddhan, the sorcerers of Thulask, there were five other wizards that went with Evagh on that voyage, having been chosen by Rlim Shaikorth. They too had been tempered to the coldness by Yikilth, and their houses had been transported to the berg by unknown enchantment. They were outlandish and uncouth men, called Polarians, from islands nearer the pole than broad Thulask; and Evagh could understand little of their ways; and their sorcery was foreign to him; and their speech was unintelligible; nor was it known to the Thulaskians.

Daily the eight wizards found on their tables all the provender necessary for human sustenance; though they knew not the agency by which it was supplied. All were united in the worship of the white worm; and all, it seemed, were content in a measure with their lot, and were fain of that unearthly lore and dominion which the worm had promised them. But Evagh was uneasy at heart, and rebelled in secret against his thralldom to Rlim Shaikorth; and he beheld with revulsion the doom that went forth eternally from Yikilth upon lovely cities and fruitful ocean-shores. Ruthfully he saw the blasting of flower-girdled Cerngoth, and the boreal stillness that descended on the thronged streets of Leqquan, and the frost that seared with sudden whiteness the garths and orchards of the sea-fronting valley of Aguil. And sorrow was in his heart for the fishing-coracles and the biremes of trade and warfare that floated manless after they had met Yikilth.

Ever southward sailed the great ice-berg, bearing its lethal winter to lands where the summer sun rode high. And Evagh kept his own counsel, and followed in all ways the custom of Dooni and Ux Loddhan and the others. At intervals that were regulated by the motions of the circumpolar stars, the eight warlocks climbed to that lofty chamber in which Rlim Shaikorth abode perpetually, half-coiled on his dais of ice. There, in a ritual whose cadences corresponded to the falling of those eyelike tears that were wept by the worm, and with genuflections timed to the yawning and shutting of his mouth, they yielded to Rlim Shaikorth the required adoration. Sometimes the worm was silent, and sometimes he bespoke them, renewing vaguely the promises he had made. And Evagh learned from the others that the worm slept for a period at each darkening of the moon; and only at that time did the sanguine tears suspend their falling, and the mouth forbear its alternate closing and gaping.

At the third repetition of the rites of worship, it came to pass that only seven wizards climbed to the tower. Evagh, counting their number, perceived that the missing man was one of the five outlanders. Afterwards, he questioned Dooni and Ux Loddhan regarding this matter, and made signs of inquiry to the four northrons; but it seemed that the fate of the absent warlock was a thing mysterious to all. Nothing was seen or heard of him from that time; and Evagh, pondering long and deeply, was somewhat disquieted. For, during the ceremony in the tower chamber, it had seemed to him that the worm was grosser of bulk and girth than on any prior occasion.

Covertly he asked what manner of nutriment was required by Rlim Shaikorth. Concerning this, there was much dubiety and dispute: for Ux Loddhan maintained that the worm fed on nothing less unique than the hearts of white Arctic bears; while Dooni swore that his rightful nourishment was the liver of whales. But, to their knowledge, the worm had not eaten during their sojourn upon Yikilth; and both averred that the intervals between his times of feeding were longer than those of any terrestrial creature, being computable not in hours or days but in whole years.

Still the ice-berg followed its course, ever vaster and more prodigious beneath the heightening sun; and again, at the star-appointed time, which was the forenoon of every third day, the sorcerers convened in the presence of Rlim Shaikorth. To the perturbation of all, their number was now but six; and the lost warlock was another of the outlanders. And the worm had greatened still more in size; and the increase was visible as a thickening of his whole body from head to tail.

Deeming these circumstances an ill augury, the six made fearful supplication to the worm in their various tongues, and implored him to tell them the fate of their absent fellows. And the worm answered; and his speech was intelligible to Evagh and Ux Loddhan and Dooni and the three northrons, each thinking that he had been addressed in his native language.

“This matter is a mystery concerning which ye shall all receive enlightenment in turn. Know this: the two that have vanished are still present; and they and ye also shall share even as I have promised in the ultramundane lore and empery of Rlim Shaikorth.”

Afterwards, when they had descended from the tower, Evagh and the two Thulaskians debated the interpretation of this answer. Evagh maintained that the import was sinister, for truly their missing companions were present only in the worm’s belly; but the others argued that these men had undergone a more mystical translation and were now elevated beyond human sight and hearing. Forthwith they began to make ready with prayer and austerity, in expectation of some sublime apotheosis which would come to them in due turn. But Evagh was still fearful; and he could not trust the equivocal pledges of the worm; and doubt remained with him.
