Exhausted they must all have been, but there perhaps was more to it than that. Deep in one of the saddlebags, a tiny bead of light glowed under a glass dial, brightened, dimmed, and then grew bright again. Forces and currents, invisible to the eye but nonetheless powerful, moved through the steaming fog which lay on the Palood. In dark places, unknown to normal mankind, consultations were held, fears explored, and decisions taken. Curious things stirred under the slime, and the Unclean concentrated their vast powers on the heart of the bog, where a telltale glow on one of their hidden control boards told them a deadly enemy of unknown power, a foe to their fell purposes, now lay concealed. From drowned cities, lost and buried forever under the fens and mud of the marshland, came the flicker of strange movement and unnatural life.
The morning grew old. A pale sun shone through a watery fog and yellowish vapor rack. No wind disturbed the quiet pools, and the tops of the tall reeds and docks hung limp in the mists and humid steams which rose from the surface of the great fen. Still the three drowsed on, occasionally murmuring or groaning softly in the tip of their overlong sleep. Afternoon passed and still they lay, unmoving. The light died slowly as the sun sank into the cloudy west. Now the white fogs of night began to rise from the meres and dark waters, mingling with those left from the day, until vision shrank and one could see only in streaks where the veils curled aside before reclosing and forming new banks of haze and murk.
At this dree hour came the Dweller in the Mist. From what foul den or lurking place it issued, none would ever know. The ghastly cosmic forces unleashed by The Death had made the mingling of strange life possible, and things had grown and thought which should never have known the breath of life. Of such was the Dweller. How it had found the three, only it, or perhaps the Lords of the Unclean, could have said. Perhaps the telltale in the saddlebag helped. It had found them, and that was enough.
Some warning gave Hiero a fighting chance, some spark sent by the trained soul the Abbey fathers had taught, to the trained mind which they had disciplined. He woke, clutching the silver cross and sword upon its neck thong, and saw before him the doom which had stolen upon them as they slept.
The vapors had parted briefly over the dark lagoon which lay before the entrance to their refuge. Around a corner of the next islet of mud and reeds came a small boat. It was hardly more than a skiff, of some black wood, with a rounded bow and stern. On it, standing erect and motionless, was a figure swathed in a whitish cloak and hood. What propelled the strange craft was not apparent, but it moved steadily through the oily water, coming straight for the place where the priest now sat, staring.
Before the shrouded figure in the pale draperies, there came out a wave of fell power and evil intent which struck Hiero and piled over him like some vast and clammy net. Beside him, the two faithful beasts apparently slept on, unmoving. The force which the Dweller commanded held them in their places, if not asleep, at least numbed into unconsciousness. The man knew that something had caught them all unaware which might, in truth, destroy the bodies of the two animals, but which was really directed at him, and the aim of which was the total enslavement of his mind and soul. Here, he knew on the instant, was the embodiment of the warning given by the little Eyed Cross.
All this flashed through his mind as he prepared to do battle and the black skiff glided to a halt, nosing into the soft mud bank not ten feet from where he sat. From the place of his inner being, Hiero looked into the shadows under the pale hood; and from that caverned place, the Dweller’s eyes, two pits of ocherous evil, stared silently back.
In one sense, though only the broadest, it was another mental struggle, such as Hiero had waged unsuccessfully against S’nerg.
But there were important differences. The Unclean wizard, bad as he was, was still a man, and his control owed much to simple hypnotic techniques, amplified and strengthened by years of training and practice in telepathic control. That which was called the Dweller was not remotely human, and the powers it drew upon were somehow inherent and natural to it. It sought control by a form of mental parasitism, as a vampire sucks blood by instinct, rather than by any design. Its form of attack was non-physical but two-pronged.
Hiero felt an intensification of the smothering, clinging feeling which had announced the Dweller’s coming. His mind, his body, his inner processes, his center of being, felt steadily constricted and squeezed, as well as feeling a constant drain of energy. In addition, however, a subtle feeling of pleasure was projected at the same time, a sense that the Dweller meant all that was good and beneficial, both to his physical and to his spiritual well-being. There was a subtle biological side effect, sexual in nature, which filled Hiero’s mind with mingled loathing and delight at one and the same time. The overall attack was very powerful. The psychic energy of the swamp-thing seemed almost a visible aura around its shrouded head, the bulk and shape of which, even under its wrappings, looked all wrong and somehow not physically possible or proper.
One hand clutching the Cross and Sword on his breast, the priest fought grimly back. The part of his total being which was being seduced by the promise of unspeakable pleasures he concentrated on memories of strength and austerity. Such were the Abbey choir services of the motet evenings, the mental courts where novices battled one another in silent struggles of the mind. He had obtained just enough time before the Dweller’s net was cast to start reciting the table of logarithms with yet another part of his brain. Long ago, the Abbey masters had learned that the ancient mathematical formulas were a strong defense against mental attack. Based as they were on logic, repetition, and disciplined series, they formed a strong barrier, when properly utilized, against the illogic and confusion which, of necessity, were the chief mental weapons of the Unclean. Yet it was a struggle which Hiero felt to be steadily going against him. The draining power of the Dweller seemed inexhaustible. Each time the priest blocked off an avenue into his mind by which it tried to lure him into acquiescence, another similar attack would commence on some other flaw in his psyche. And the steady compression of what Hiero felt to be a net never ceased its remorseless constriction as well. The appeals to his gross senses and the black, strangling clutch at his thought processes seemed more and more hopeless to combat.
Yet, even as his will seemed to him to weaken, his courage and resolution actually flared higher in response to the danger. And an unexpected help came, unrealized in fact at this time, from the dead mind of S’nerg, whom the priest had slain. His struggle with the adept had given Hiero’s own dormant powers a new strength of which he had as yet no conception. He battled on, therefore, no hint of yielding in his soul, determined that if this nightmare from the swamp murk were to conquer him, it would only be at the price of his death!
The physical world about him had completely disappeared. He was conscious of only the black foulness before him, the veil from which stared the twin pools of lambent horror, the eyes of the Dweller! And in those eyes he saw, or sensed, for the first time, something change, some shift or evasion. So close now was his rapport with the thing before him that he realized at once what had happened. It was no longer attacking! The doubt, faint as it was, had interfered with the stream of projections and mental bolts which the Dweller had been using, and even the tiny hesitation had broken the flow of its concentration. To gain the victories to which it had been used, weakness and weariness must help and undisciplined minds must inevitably yield to the frightful powers it both controlled and lived by.
