Ralibar Vooz, high magistrate and redoubtable hunter, was both puzzled and irritated by this behavior of the smoke. Likewise, the aspect of the rocks around him was disconcertingly and unpleasantly deceitful. He was wasting too much time in an exploration idle and quite foreign to the real business of the day; but it was not his nature to abandon any enterprise no matter how trivial, without reaching the set goal. Halloing loudly to his men, who must have climbed the cliff by now, he went on toward the elusive smoke.
It seemed to him, once or twice, that he heard the answering shouts of his followers, very faint and indistinct, as if across some mile-wide chasm. Again he called lustily, but this time there was no audible reply. Going a little farther, he began to detect among the rocks beside him a peculiar conversational droning and muttering in which four or five different voices appeared to take part. Seemingly they were much nearer at hand than the smoke, which had now receded like a mirage. One of the voices was clearly that of a Hyperborean; but the others possessed a timbre and accent which Ralibar Vooz, in spite of his varied ethnic knowledge, could not associate with any branch or subdivision of mankind. They affected his ears in a most unpleasant fashion, suggesting by turns the hum of great insects, the murmurs of fire and water, and the rasping of metal.
Ralibar Vooz emitted a hearty and somewhat ireful bellow to announce his coming to whatever persons were convened amid the rocks. His weapons and accouterments clattering loudly, he scrambled over a sharp lava-ridge toward the voices.
Topping the ridge, he looked down on a scene that was both mysterious and unexpected. Below him, in a circular hollow, there stood a rude hut of boulders and stone fragments roofed with cedar boughs. In front of this hovel, on a large flat block of obsidian, a fire burned with flanes alternately blue, green and white; and from it rose the pale, thin spiral of smoke whose situation had illuded him so strangely.
An old man, withered and disreputable-looking, in a robe that appeared no less antique and unsavory than himself, was standing near to the fire. He was not engaged in any visible culinary operations; and, in view of the torrid sun, it hardly seemed that he required the warmth given by the queer-colored blaze. Aside from this individual, Ralibar Vooz laoked in vain for the participants of the muttered conversation he had just overheard. He thought there was an evanescent fluttering of dim, grotesque, shadows around the obsidian block; but the shadows faded and vanished in an instant; and, since there were no objects or beings that could have cast them, Ralibar Vooz deemed that he had been victimized by another of those highly disagreeable optic illusions in which that part of the mountain Vormithadreth seemed to abound.
The old man eyed the hunter with a fiery gaze and began to curse him in fluent but somewhat archaic diction as he descended into the hollow. At the same time, a lizard-tailed and sooty-feathered bird, which seemed to belong to some night-flying species of archaeopteryx, began to snap its toothed beak and flap its digited wings on the objectionably shapen stela that served it for a perch. This stela, standing on the lee side of the fire and very close to it, had not been perceived by Ralibar Vooz at first glance.
"May the ordure of demons bemire you from heel to crown!" cried the venomous ancient. "O lumbering, bawling idiot! you have ruined a most promising and important evocation. How you came here I cannot imagine. I have surrounded this place with twelve circles of illusion, whose effect is multiplied by their myriad intersections; and the chance that any intruder would ever find his way to my abode was mathematically small and insignificant. Ill was that chance which brought you here: for They that you have frightened away will not return until the high stars repeat a certain rare and quickly passing conjunction; and much wisdom is lost to me in the interim."
"How now, varlet!" said Ralibar Vooz, astonished and angered by this greeting, of which he understood little save that his presence was unwelcome to the old man. "Who are you that speak so churlishly to a magistrate of Commoriom and a cousin to King Homquat? I advise you to curb such insolence: for, if so I wish, it lies in my power to serve you even as I serve the Voormis. Though methinks," he added, "your pelt is far too filthy and verminous to merit room amid my trophies of the chase."
"Know that I am the sorcerer Ezdagor," proclaimed the ancient, his voice echoing among the rocks with dreadful sonority. "By choice I have lived remote from cities and men; nor have the Voormis of the mountain troubled me in my magical seclusion. I care not if you are the magistrate of all swinedom or a cousin to the king of dogs. In retribution for the charm you have shattered, the business you have undone by this oafish trespass, I shall put upon you a most dire and calamitous and bitter geas."
