Then he noticed with terror that the wings of the night-gaunts were not flapping any more. The horned and faceless steeds had folded their membraneous appendages, and were resting quite passive in the chaos of wind that whirled and chuckled as it bore them on. A force not of earth had seized on the army, and ghouls and night-gaunts alike were powerless before a current which pulled madly and relentlessly into the north whence no mortal had ever returned. At length a lone pallid light was seen on the skyline ahead, thereafter rising steadily as they approached, and having beneath it a black mass that blotted out the stars. Carter saw that it must be some beacon on a mountain, for only a mountain could rise so vast as seen from so prodigious a height in the air.
Higher and higher rose the light and the blackness beneath it, till half the northern sky was obscured by the rugged conical mass. Lofty as the army was, that pale and sinister beacon rose above it, towering monstrous over all peaks and concernments of earth, and tasting the atomless aether where the cryptical moon and the mad planets reel. No mountain known of man was that which loomed before them. The high clouds far below were but a fringe for its foothills. The gasping dizziness of topmost air was but a girdle for its loins. Scornful and spectral climbed that bridge betwixt earth and heaven, black in eternal night, and crowned with a pshent of unknown stars whose awful and significant outline grew every moment clearer. Ghouls meeped in wonder as they saw it, and Carter shivered in fear lest all the hurtling army be dashed to pieces on the unyielding onyx of that Cyclopean cliff.
Higher and higher rose the light, till it mingled with the loftiest orbs of the zenith and winked down at the flyers with lurid mockery. All the north beneath it was blackness now; dread, stony blackness from infinite depths to infinite heights, with only that pale winking beacon perched unreachably at the top of all vision. Carter studied the light more closely, and saw at last what lines its inky background made against the stars. There were towers on that titan mountain-top; horrible domed towers in noxious and incalculable tiers and clusters beyond any dreamable workmanship of man; battlements and terraces of wonder and menace, all limned tiny and black and distant against the starry pshent that glowed malevolently at the uppermost rim of sight. Capping that most measureless of mountains was a castle beyond all mortal thought, and in it glowed the daemon-light. Then Randolph Carter knew that his quest was done, and that he saw above him the goal of all forbidden steps and audacious visions; the fabulous, the incredible home of the Great Ones atop unknown Kadath.
Even as he realised this thing, Carter noticed a change in the course of the helplessly wind-sucked party. They were rising abruptly now, and it was plain that the focus of their flight was the onyx castle where the pale light shone. So close was the great black mountain that its sides sped by them dizzily as they shot upward, and in the darkness they could discern nothing upon it. Vaster and vaster loomed the tenebrous towers of the nighted castle above, and Carter could see that it was well-nigh blasphemous in its immensity. Well might its stones have been quarried by nameless workmen in that horrible gulf rent out of the rock in the hill pass north of Inganok, for such was its size that a man on its threshold stood even as an ant on the steps of earth’s loftiest fortress. The pshent of unknown stars above the myriad domed turrets glowed with a sallow, sickly flare, so that a kind of twilight hung about the murky walls of slippery onyx. The pallid beacon was now seen to be a single shining window high up in one of the loftiest towers, and as the helpless army neared the top of the mountain Carter thought he detected unpleasant shadows flitting across the feebly luminous expanse. It was a strangely arched window, of a design wholly alien to earth.
The solid rock now gave place to the giant foundations of the monstrous castle, and it seemed that the speed of the party was somewhat abated. Vast walls shot up, and there was a glimpse of a great gate through which the voyagers were swept. All was night in the titan courtyard, and then came the deeper blackness of inmost things as a huge arched portal engulfed the column. Vortices of cold wind surged dankly through sightless labyrinths of onyx, and Carter could never tell what Cyclopean stairs and corridors lay silent along the route of his endless aërial twisting. Always upward led the terrible plunge in darkness, and never a sound, touch, or glimpse broke the dense pall of mystery. Large as the army of ghouls and night-gaunts was, it was lost in the prodigious voids of that more than earthly castle. And when at last there suddenly dawned around him the lurid light of that single tower room whose lofty window had served as a beacon, it took Carter long to discern the far walls and high, distant ceiling, and to realise that he was indeed not again in the boundless air outside.
