At evening of the second day, after passing through the wildest and oldest portion of the immemorial wood, he came to the steep, stony valley that led to his destination. This valley was the fountain-head of the Isoile, which had dwindled to a mere rivulet. In the brown twilight, between sunset and moonrise, he saw the lights of the Cistercian monastery; and opposite, on the piled, forbidding scarps, the grim and rugged mass of the ruinous stronghold of Ylourgne, with wan and wizard fires flickering behind its high embrasures. Apart from these fires, there was no sign of occupation; and he did not hear at any time the dismal noises reported by the monks.
Gaspard waited till the round moon, yellow as the eye of some immense nocturnal bird, had begun to peer above the darkling valley. Then, very cautiously, since the neighborhood was strange to him, he started to make his way toward the somber, brooding castle.
Even for one well-used to such climbing, the escalade would have offered enough difficulty and danger by moonlight. Several times, finding himself at the bottom of a sheer cliff, he was compelled to retrace his hard-won progress; and often he was saved from falling only by stunted shrubs and briars that had taken root in the niggard soil. Breathless, with torn raiment, and scored and bleeding hands, he gained at length the shoulder of the craggy height, below the walls.
Here he paused to recover breath and recuperate his flagging strength. He could see from his vantage the pale reflection as of hidden flames, that beat upward on the inner wall of the high-built donjon. He heard a low hum of confused noises, whose distance and direction were alike baffling. Sometimes they seemed to float downward from the black battlements, sometimes to issue from subterranean depths far in the hill.
Apart from this remote, ambiguous hum, the night was locked in a mortal stillness. The very winds appeared to shun the vicinity of the dread castle. An unseen, clammy cloud of paralyzing evil hung removeless upon all things; and the pale, swollen moon, the patroness of witches and sorcerers, distilled her green poison above the crumbling towers in a silence older than time.
Gaspard felt the obscenely clinging weight of a more burdenous thing than his own fatigue when he resumed his progress toward the barbican. Invisible webs of the waiting, ever-gathering evil seemed to impede him. The slow, noisome flapping of intangible wings was heavy in his face. He seemed to breathe a surging wind from unfathomable vaults and caverns of corruption. Inaudible howlings, derisive or minatory, thronged in his ears, and foul hands appeared to thrust him back. But, bowing his head as if against a blowing gale, he went on and climbed the mounded ruin of the barbican, into the weedy courtyard.
The place was deserted, to all seeming; and much of it was still deep in the shadows of the walls and turrets. Nearby in the black, silver-crenelated pile, Gaspard saw the open, cavernous doorway described by the monks. It was lit from within by a lurid glare, wannish and eerie as marsh-fires. The humming noise, now audible as a muttering of voices, issued from the doorway; and Gaspard thought that he could see dark, sooty figures moving rapidly in the lit interior.
Keeping in the further shadows, he stole along the courtyard, making a sort of circuit amid the ruins. He did not dare to approach the open entrance for fear of being seen; though, as far as he could tell, the place was unguarded.
He came to the donjon, on whose upper wall the wan light flickered obliquely through a sort of rift in the long building adjacent. This opening was at some distance from the ground; and Gaspard saw that it had been formerly the door to a stone balcony. A flight of broken steps led upward along the wall to the half-crumbled remnant of this balcony; and it occurred to the youth that he might climb the steps and peer unobserved into the interior of Ylourgne.
Some of the stairs were missing; and all were in heavy shadow. Gaspard found his way precariously to the balcony, pausing once in considerable alarm when a fragment of the worn stone, loosened by his footfall, dropped with a loud clattering on the courtyard flags below. Apparently it was unheard by the occupants of the castle; and after a little he resumed his climbing.
Cautiously he neared the large, ragged opening through which the light poured upward. Crouching on a narrow ledge, which was all that remained of the balcony, he peered in on a most astounding and terrific spectacle, whose details were so bewildering that he could barely comprehend their import till after many minutes.
It was plain that the story told by the monks—allowing for their religious bias—had been far from extravagant. Almost the whole interior of the half-ruined pile had been torn down and dismantled to afford room for the activities of Nathaire: in itself a superhuman task for whose execution the sorcerer must have employed a legion of familiars as well as his ten pupils.
The vast chamber was fitfully illumed by the glare of athanors and braziers; and, above all, by the weird glimmering from the huge stone vats. Even from his high vantage, the watcher could not see the contents of these vats; but a white luminosity poured upward from the rim of one of them, and a flesh-tinted phosphorescence from the other.
Gaspard had seen certain of the experiments and evocations of Nathaire, and was all too familiar with the appurtenances of the dark arts. Within certain limits, he was not squeamish; nor was it likely that he would have been terrified overmuch by the shadowy, uncouth shapes of demons who toiled in the pit below him side by side with the black-clad pupils of the sorcerer. But a cold horror clutched his heart when he saw the incredible, enormous thing that occupied the central floor: the colossal human skeleton a hundred feet in length, stretching for more than the extent of the old castle hall; the skeleton whose bony right foot the group of men and devils, to all appearance, were busily clothing with human flesh!
The prodigious and macabre framework, complete in every part, with ribs like arches of some Satanic nave, shone as if it were still heated by the fires of an infernal welding. It seemed to shimmer and burn with unnatural life, to quiver with malign disquietude in the flickering glare and gloom. The great finger-bones, curving claw-like on the floor, appeared as if they were about to close upon some helpless prey. The tremendous teeth were set in an everlasting grin of sardonic cruelty and malice. The hollow eye-sockets, deep as Tartarean wells, appeared to seethe with myriad, mocking lights, like the eyes of elementals swimming upward in obscene shadow.
Gaspard was stunned by the shocking and stupendous phantasmagoria that yawned before him like a peopled hell. Afterwards, he was never wholly sure of certain things, and could remember very little of the actual manner in which the work of the men and their assistants was being carried on. Dim, dubious, bat-like creatures seemed to be flitting to and fro between one of the stone vats and the group that toiled like sculptors, clothing the bony foot with a reddish plasm which they applied and moulded like so much clay. Gaspard thought, but was not certain later, that this plasm, which gleamed as if with mingled blood and fire, was being brought from the rosy-litten vat in vessels borne by the claws of the shadowy flying creatures. None of them, however, approached the other vat, whose wannish light was momently enfeebled, as if it were dying down.
He looked for the minikin figure of Nathaire, whom he could not distinguish in the crowded scene. The sick necromancer—if he had not already succumbed to the little-known disease that had long wasted him like an inward flame—was no doubt hidden from view by the colossal skeleton and was perhaps directing the labors of the men and demons from his couch.
Spell-bound on that precarious ledge, the watcher failed to hear the furtive, cat-like feet that were climbing behind him on the ruinous stairs. Too late, he heard the clink of a loose fragment close upon his heels; and turning in startlement, he toppled into sheer oblivion beneath the impact of a cudgel-like blow, and did not even know that the beginning fall of his body toward the courtyard had been arrested by his assailant’s arms.
