A palpable heat emanated from these hellish chimeras, and the earth-men retreated hastily before the flying splotches, like the blown tatters of a conflagration, that broke loose from their ever-jetting eye-flames and mouth-flames.

“My God! These monsters are supernatural!” cried Chanler, shaken and appalled.

Haines, though palpably startled, was inclined to a more orthodox explanation. “There must be some sort of television behind this,” he maintained. “Though I can’t imagine how it’s possible to project three-dimensional images, and also create the sensation of heat.… I had an idea, somehow, that our escape was being watched.”

He picked up a heavy fragment of metallic stone and heaved it at one of the glowing chimeras. Aimed unerringly, the fragment struck the frontal brow of the monster, and seemed to explode in a shower of sparks at the moment of impact. The creature flared and swelled prodigiously, and a fiery hissing became audible. Haines and Chanler were driven back by a wave of scorching heat; and their wardens followed them pace by pace on the rough bottom. Abandoning all hope of escape, they returned toward Ravormos, dogged at the same unvarying distance by the monsters as they toiled through yielding sand and over the ledges and riffles.

Reaching the point where they had descended into the river-channel, they found its upper stretches guarded by two more of these terrific dragons. There was no other recourse than to climb the lofty shelves into the acclivitous tunnel. Weary with their long flight, and enervated by a dull despair, they found themselves again in the outer hall, with two of their guardians now preceding them like an escort of infernal honor. Both were stunned by a realization of the awful and mysterious powers of Vulthoom; and even Haines had become silent, though his brain was still busy with a futile and desperate probing. Chanler, more sensitive, suffered all the chills and terrors that his literary imagination could inflict upon him under the circumstances.

They came at length to the columned gallery that circled the vast abyss. Midway in this gallery, the chimeras who preceded the earth-men turned upon them suddenly with a fearsome belching of flames; and, as they paused in their intimidation, the two behind continued to advance toward them with a hissing as of Satanic salamanders. In that narrowing space, the heat was like a furnace-blast, and the columns afforded no shelter. From the gulf below, where the Martian titans toiled perpetually, a stupefying thunder rose to assail them at the same time; and noxious fumes were blown toward them in writhing coils.

“Looks as if they are going to drive us into the gulf,” Haines panted as he sought to draw breath in the fiery air. He and Chanler reeled before the looming monsters, and even as he spoke, two more of these hellish apparitions flamed into being at the gallery’s verge, as if they had risen from the gulf to render impossible that fatal plunge which alone could have offered an escape from the others.

Half swooning, the earth-men were dimly aware of a change in the menacing chimeras. The flaming bodies dulled and shrank and darkened, the heat lessened, the fires died down in the mouths and eye-pits. At the same time, the creatures drew closer, fawning loathsomely, and revealing whitish tongues and eyeballs of jet.

The tongues seemed to divide... they grew paler... they were like flower-petals that Haines and Chanler had seen somewhere, at a former time. The breath of the chimeras, like a soft gale, was upon the faces of the earth-men... and the breath was a cool and spicy perfume that they had known before... the narcotic perfume that had overcome them following their audience with the hidden master of Ravormos.… Moment by moment, the monsters turned to prodigious blossoms; the pillars of the gallery became gigantic trees in a glamour of primal dawn; the thunders of the pit were lulled to a far-off sighing as of gentle seas on Edenic shores. The teeming terrors of Ravormos, the threat of a shadowy doom, were as things that had never been. Haines and Chanler, oblivious, were lost in the paradise of the unknown drug....

Haines, awakening darkly, found that he lay on the stone floor in the circling colonnade. He was alone, and the fiery chimeras had vanished. The shadows of his opiate swoon were roughly dissipated by the clangors that still mounted from the neighboring gulf. With growing consternation and horror, he recalled everything that had happened.

He arose giddily to his feet, peering about in the semi-twilight of the gallery for some trace of his companion. The petrified fungus-club that Chanler had carried, as well as his own weapon, were lying where they had fallen from the fingers of the overpowered men. But Chanler was gone; and Haines shouted aloud with no other response than had the eerily prolonged echoes of the deep arcade.

Impelled by an urgent feeling that he must find Chanler without delay, he recovered his heavy mace and started along the gallery. It seemed that the weapon could be of little use against the preternatural servants of Vulthoom; but somehow, the metallic weight of the bludgeon was a thing that reassured him.

Nearing the great corridor that ran to the core of Ravormos, Haines was overjoyed when he saw Chanler coming to meet him. Before he could call out a cheery greeting, he heard Chanler’s voice:

“Hello, Bob, this is my first televisual appearance in tri-dimensional form. Pretty good, isn’t it? I’m in the private laboratory of Vulthoom, and Vulthoom has persuaded me to accept his proposition. As soon as you’ve made up your mind to do likewise, we’ll return to Ignarh with full instructions regarding our terrestrial mission, and funds amounting to a million dollars each. Think it over, and you’ll see that there’s nothing else to do. When you’ve decided to join us, follow the main corridor through Ravormos, and Ta-Vho-Shai will meet you and bring you into the laboratory.”

At the conclusion of this astounding speech, the figure of Chanler, without seeming to wait for any reply from Haines, stepped lightly to the gallery’s verge and floated out among the wreathing vapors. There, smiling upon Haines, it vanished like a phantom.

To say that Haines was thunderstruck would be putting it feebly indeed. In all verisimilitude, the figure and voice had been those of the flesh-and-blood Chanler. He felt an eerie chill before the thaumaturgy of Vulthoom, which could bring about a projection so veridical as to deceive him in this manner. He was shocked and horrified beyond measure by Chanler’s capitulation; but somehow, it did not occur to him that any imposture had been practiced.

“That devil has gotten him,” thought Haines. “But I’d never have believed it. I didn’t think he was that kind of a fellow at all.”

Sorrow, anger, bafflement and amazement filled him alternately as he strode along the gallery; nor, as he entered the inner hall, was he able to decide on any clearly effective course of action. To yield, as Chanler had avowedly done, was unthinkably repugnant to him. If he could see Chanler again, perhaps he could persuade him to change his mind and resume an unflinching opposition to the alien entity. It was a degradation, and a treason to humankind, for any earth-man to lend himself to the more than doubtful schemes of Vulthoom. Apart from the projected invasion of Earth, and the spread of the strange, subtle narcotic, there was the ruthless destruction of Ignar-Luth that would occur when Vulthoom’s ether-vessel should blast its way to the planet’s surface. It was his duty, and Chanler’s, to prevent all this if prevention were humanly possible. Somehow, they—or he alone if necessary—must stem the cavern-incubated menace. Bluntly honest himself, there was no thought of temporizing even for an instant.

Still carrying the mineraloid club, he strode on for several minutes, his brain preoccupied with the dire problem but powerless to arrive at any solution. Through a habit of observation more or less automatic with the veteran space-pilot, he peered through the doorways of the various rooms that he passed, where the cupels and retorts of a foreign chemistry were tended by age-old colossi. Then, without premeditation, he came to the deserted room in which were the three mighty receptacles that Ta-Vho-Shai had called the Bottles of Sleep. He remembered what the Aihai had said concerning their contents.
