Presently three other ghasts hopped out to join their fellow, and a ghoul glibbered softly at Carter that their absence of battle-scars was a bad sign. It proved that they had not fought the Gug sentry at all, but had merely slipped past him as he slept, so that their strength and savagery were still unimpaired and would remain so till they had found and disposed of a victim. It was very unpleasant to see those filthy and disproportioned animals which soon numbered about fifteen, grubbing about and making their kangaroo leaps in the grey twilight where titan towers and monoliths arose, but it was still more unpleasant when they spoke among themselves in the coughing gutturals of ghasts. And yet, horrible as they were, they were not so horrible as what presently came out of the cave after them with disconcerting suddenness.
It was a paw, fully two feet and a half across, and equipped with formidable talons. Alter it came another paw, and after that a great black-furred arm to which both of the paws were attached by short forearms. Then two pink eyes shone, and the head of the awakened Gug sentry, large as a barrel, wabbled into view. The eyes jutted two inches from each side, shaded by bony protuberances overgrown with coarse hairs. But the head was chiefly terrible because of the mouth. That mouth had great yellow fangs and ran from the top to the bottom of the head, opening vertically instead of horizontally.
But before that unfortunate Gug could emerge from the cave and rise to his full twenty feet, the vindictive ghasts were upon him. Carter feared for a moment that he would give an alarm and arouse all his kin, till a ghoul softly glibbered that Gugs have no voice but talk by means of facial expression. The battle which then ensued was truly a frightful one. From all sides the venomous ghasts rushed feverishly at the creeping Gug, nipping and tearing with their muzzles, and mauling murderously with their hard pointed hooves. All the time they coughed excitedly, screaming when the great vertical mouth of the Gug would occasionally bite into one of their number, so that the noise of the combat would surely have aroused the sleeping city had not the weakening of the sentry begun to transfer the action farther and farther within the cavern. As it was, the tumult soon receded altogether from sight in the blackness, with only occasional evil echoes to mark its continuance.
Then the most alert of the ghouls gave the signal for all to advance, and Carter followed the loping three out of the forest of monoliths and into the dark noisome streets of that awful city whose rounded towers of cyclopean stone soared up beyond the sight. Silently they shambled over that rough rock pavement, hearing with disgust the abominable muffled snortings from great black doorways which marked the slumber of the Gugs. Apprehensive of the ending of the rest hour, the ghouls set a somewhat rapid pace; but even so the journey was no brief one, for distances in that town of giants are on a great scale. At last, however, they came to a somewhat open space before a tower even vaster than the rest; above whose colossal doorway was fixed a monstrous symbol in bas-relief which made one shudder without knowing its meaning. This was the central tower with the sign of Koth, and those huge stone steps just visible through the dusk within were the beginning of the great flight leading to upper dreamland and the enchanted wood.
There now began a climb of interminable length in utter blackness: made almost impossible by the monstrous size of the steps, which were fashioned for Gugs, and were therefore nearly a yard high. Of their number Carter could form no just estimate, for he soon became so worn out that the tireless and elastic ghouls were forced to aid him. All through the endless climb there lurked the peril of detection and pursuit; for though no Gug dares lift the stone door to the forest because of the Great One's curse, there are no such restraints concerning the tower and the steps, and escaped ghasts are often chased, even to the very top. So sharp are the ears of Gugs, that the bare feet and hands of the climbers might readily be heard when the city awoke; and it would of course take but little time for the striding giants, accustomed from their ghast-hunts in the vaults of Zin to seeing without light, to overtake their smaller and slower quarry on those cyclopean steps. It was very depressing to reflect that the silent pursuing Gugs would not be heard at all, but would come very suddenly and shockingly in the dark upon the climbers. Nor could the traditional fear of Gugs for ghouls be depended upon in that peculiar place where the advantages lay so heavily with the Gugs. There was also some peril from the furtive and venomous ghasts, which frequently hopped up onto the tower during the sleep hour of the Gugs. If the Gugs slept long, and the ghasts returned soon from their deed in the cavern, the scent of the climbers might easily be picked up by those loathsome and ill-disposed things; in which case it would almost be better to be eaten by a Gug.
Then, after aeons of climbing, there came a cough from the darkness above; and matters assumed a very grave and unexpected turn.
It was clear that a ghast, or perhaps even more, had strayed into that tower before the coming of Carter and his guides; and it was equally clear that this peril was very close. After a breathless second the leading ghoul pushed Carter to the wall and arranged his kinfolk in the best possible way, with the old slate tombstone raised for a crushing blow whenever the enemy might come in sight. Ghouls can see in the dark, so the party was not as badly off as Carter would have been alone. In another moment the clatter of hooves revealed the downward hopping of at least one beast, and the slab-bearing ghouls poised their weapon for a desperate blow. Presently two yellowish-red eyes flashed into view, and the panting of the ghast became audible above its clattering. As it hopped down to the step above the ghouls, they wielded the ancient gravestone with prodigious force, so that there was only a wheeze and a choking before the victim collapsed in a noxious heap. There seemed to be only this one animal, and after a moment of listening the ghouls tapped Carter as a signal to proceed again. As before, they were obliged to aid him; and he was glad to leave that place of carnage where the ghast's uncouth remains sprawled invisible in the blackness.
At last the ghouls brought their companion to a halt; and feeling above him, Carter realised that the great stone trap door was reached at last. To open so vast a thing completely was not to be thought of, but the ghouls hoped to get it up just enough to slip the gravestone under as a prop, and permit Carter to escape through the crack. They themselves planned to descend again and return through the city of the Gugs, since their elusiveness was great, and they did not know the way overland to spectral Sarkomand with its lion-guarded gate to the abyss.
Mighty was the straining of those three ghouls at the stone of the door above them, and Carter helped push with as much strength as he had. They judged the edge next the top of the staircase to be the right one, and to this they bent all the force of their disreputably nourished muscles. Alter a few moments a crack of light appeared; and Carter, to whom that task had been entrusted, slipped the end of the old gravestone in the aperture. There now ensued a mighty heaving; but progress was very slow, and they had of course to return to their first position every time they failed to turn the slab and prop the portal open.
Suddenly their desperation was magnified a thousand fold by a sound on the steps below them. It was only the thumping and rattling of the slain ghast's hooved body as it rolled down to lower levels; but of all the possible causes of that body's dislodgement and rolling, none was in the least reassuring. Therefore, knowing the ways of Gugs, the ghouls set to with something of a frenzy; and in a surprisingly short time had the door so high that they were able to hold it still whilst Carter turned the slab and left a generous opening. They now helped Carter through, letting him climb up to their rubbery shoulders and later guiding his feet as he clutched at the blessed soil of the upper dreamland outside. Another second and they were through themselves, knocking away the gravestone and closing the great trap door while a panting became audible beneath. Because of the Great One's curse no Gug might ever emerge from that portal, so with a deep relief and sense of repose Carter lay quietly on the thick grotesque fungi of the enchanted wood while his guides squatted near in the manner that ghouls rest.
