Then, just as he was about to creep back from that detestable flame, he saw a stirring among the vague dark forms and heard a peculiar and unmistakable sound. It was the frightened meeping of a ghoul, and in a moment it had swelled to a veritable chorus of anguish. Secure as he was in the shadow of monstrous ruins, Carter allowed his curiosity to conquer his fear, and crept forward again instead of retreating. Once in crossing an open street he wriggled worm-like on his stomach, and in another place he had to rise to his feet to avoid making a noise among heaps of fallen marble. But always he succeeded in avoiding discovery, so that in a short time he had found a spot behind a titan pillar whence he could watch the whole green-litten scene of action. There, around a hideous fire fed by the obnoxious stems of lunar fungi, there squatted a stinking circle of the toad-like moon-beasts and their almost-human slaves. Some of these slaves were heating curious iron spears in the leaping flames, and at intervals applying their white-hot points to three tightly trussed prisoners that lay writhing before the leaders of the party. From the motions of their tentacles Carter could see that the blunt-snouted moon-beasts were enjoying the spectacle hugely, and vast was his horror when he suddenly recognised the frantic meeping and knew that the tortured ghouls were none other than the faithful trio which had guided him safely from the abyss and had thereafter set out from the enchanted wood to find Sarkomand and the gate to their native deeps.
The number of malodorous moon-beasts about that greenish fire was very great, and Carter saw that he could do nothing now to save his former allies. Of how the ghouls had been captured he could not guess; but fancied that the grey toad-like blasphemies had heard them inquire in Dylath-Leen concerning the way to Sarkomand and had not wished them to approach so closely the hateful plateau of Leng and the high-priest not to be described. For a moment he pondered on what he ought to do, and recalled how near he was to the gate of the ghouls’ black kingdom. Clearly it was wisest to creep east to the plaza of twin lions and descend at once to the gulf, where assuredly he would meet no horrors worse than those above, and where he might soon find ghouls eager to rescue their brethren and perhaps to wipe out the moon-beasts from the black galley. It occurred to him that the portal, like other gates to the abyss, might be guarded by flocks of night-gaunts; but he did not fear these faceless creatures now. He had learned that they are bound by solemn treaties with the ghouls, and the ghoul which was Pickman had taught him how to glibber a password they understood.
So Carter began another silent crawl through the ruins, edging slowly toward the great central plaza and the winged lions. It was ticklish work, but the moon-beasts were pleasantly busy and did not hear the slight noises which he twice made by accident among the scattered stones. At last he reached the open space and picked his way among the stunted trees and briers that had grown up therein. The gigantic lions loomed terrible above him in the sickly glow of the phosphorescent night clouds, but he manfully persisted toward them and presently crept round to their faces, knowing it was on that side he would find the mighty darkness which they guard. Ten feet apart crouched the mocking-faced beasts of diorite, brooding on Cyclopean pedestals whose sides were chiselled into fearsome bas-reliefs. Betwixt them was a tiled court with a central space which had once been railed with balusters of onyx. Midway in this space a black well opened, and Carter soon saw that he had indeed reached the yawning gulf whose crusted and mouldy stone steps lead down to the crypts of nightmare.
Terrible is the memory of that dark descent, in which hours wore themselves away whilst Carter wound sightlessly round and round down a fathomless spiral of steep and slippery stairs. So worn and narrow were the steps, and so greasy with the ooze of inner earth, that the climber never quite knew when to expect a breathless fall and hurtling down to the ultimate pits; and he was likewise uncertain just when or how the guardian night-gaunts would suddenly pounce upon him, if indeed there were any stationed in this primeval passage. All about him was a stifling odour of nether gulfs, and he felt that the air of these choking depths was not made for mankind. In time he became very numb and somnolent, moving more from automatic impulse than from reasoned will; nor did he realise any change when he stopped moving altogether as something quietly seized him from behind. He was flying very rapidly through the air before a malevolent tickling told him that the rubbery night-gaunts had performed their duty.
Awaked to the fact that he was in the cold, damp clutch of the faceless flutterers, Carter remembered the password of the ghouls and glibbered it as loudly as he could amidst the wind and chaos of flight. Mindless though night-gaunts are said to be, the effect was instantaneous; for all tickling stopped at once, and the creatures hastened to shift their captive to a more comfortable position. Thus encouraged, Carter ventured some explanations; telling of the seizure and torture of three ghouls by the moon-beasts, and of the need of assembling a party to rescue them. The night-gaunts, though inarticulate, seemed to understand what was said; and shewed greater haste and purpose in their flight. Suddenly the dense blackness gave place to the grey twilight of inner earth, and there opened up ahead one of those flat sterile plains on which ghouls love to squat and gnaw. Scattered tombstones and osseous fragments told of the denizens of that place; and as Carter gave a loud meep of urgent summons, a score of burrows emptied forth their leathery, dog-like tenants. The night-gaunts now flew low and set their passenger upon his feet, afterward withdrawing a little and forming a hunched semicircle on the ground while the ghouls greeted the newcomer.
