Fain would I have cried or spoken aloud; but horror had dried up the fount of speech. And the thing that had been Avyctes beckoned me in silence, uttering no word from its living and putrescent lips. And with eyes that were no longer eyes, but had become an oozing abomination, it peered steadily upon me. And it clutched my shoulder closely with the soft leprosy of its fingers, and led me half-swooning with revulsion along the hall, and into that room where the mummy of Oigos, who had assisted us in the threefold incantation of the serpent-men, was stationed with several of his fellows.

By the lamps which illumed the chamber, burning with pale, still, perpetual flames, I saw that the mummies stood erect along the wall in their exanimate repose, each in his wonted place with his tall shadow beside him. But the great, gaunt shadow of Oigos on the marble wall was companioned by an adumbration similar in all respects to the evil thing that had followed the master and was now incorporate with him. I remembered that Oigos had performed his share of the ritual, and had repeated an unknown stated word in turn after Avyctes; and so I knew that the horror had come to Oigos in turn, and would wreak itself upon the dead even as on the living. For the foul, anonymous thing that we had called in our presumption could manifest itself to mortal ken in no other way than this. We had drawn it from unfathomable depths of time and space, using ignorantly a dire formula; and the thing had come at its own chosen hour, to stamp itself in abomination uttermost on the evocators.

Since then, the night has ebbed away, and a second day has gone by like a sluggish ooze of horror…. I have seen the complete identification of the shadow with the flesh and the shadow of Avyctes… and also I have seen the slow encroachment of that other umbrage, mingling itself with the lank shadow and the sere, bituminous body of Oigos, and turning them to a similitude of the thing which Avyctes has become. And I have heard the mummy cry out like a living man in great pain and fear, as with the throes of a second dissolution, at the impingement of the shadow. And long since it has grown silent, like the other horror, and I know not its thoughts or its intent… . And verily I know not if the thing that has come to us be one or several; nor if its avatar will rest complete with the three that summoned it forth into time, or be extended to others.

But these things, and much else, I shall soon know; for now, in turn, there is a shadow that follows mine, drawing ever closer. The air congeals and curdles with an unseen fear; and they that were our familiars have fled from the mansion; and the great marble women seem to tremble where they stand along the walls. But the horror that was Avyctes, and the second horror that was Oigos, have left me not, and neither do they tremble. And with eyes that are not eyes, they seem to brood and watch, waiting till I too shall become as they. And their stillness is more terrible than if they had rended me limb from limb. And there are strange voices in the wind, and alien roarings upon the sea; and the walls quiver like a thin veil in the black breath of remote abysses.

So, knowing that the time is brief, I have shut myself in the room of volumes and books and have written this account. And I have taken the bright triangular tablet, whose solution was our undoing, and have cast it from the window into the sea, hoping that none will find it after us. And now I must make an end, and enclose this writing in the sealed cylinder of orichalchum, and fling it forth to drift upon the wave. For the space between my shadow and the shadow of the horror is straitened momently… and the space is no wider than the thickness of a wizard’s pen.

THE PLUTONIAN DRUG

“It is remarkable,” said Dr. Manners, “how the scope of our pharmacopoeia has been widened by interplanetary exploration. In the past thirty years, hundreds of hitherto unknown substances, employable as drugs or medical agents, have been found in the other worlds of our own system. It will be interesting to see what the Allan Farquar expedition will bring back from the planets of Alpha Centauri when—or if—it succeeds in reaching them and returning to Earth. I doubt, though, if anything more valuable than selenine will be discovered. Selenine, derived from a fossil lichen found by the first rocket-expedition to the moon in 1975, has, as you know, practically wiped out the old-time curse of cancer. In solution, it forms the base of an infallible serum, equally useful for cure or prevention.”

“I fear I haven’t kept up on a lot of the new discoveries,” said Rupert Balcoth the sculptor, Manners’ guest, a little apologetically. “Of course, everyone has heard of selenine. And I’ve seen frequent mention, recently, of a mineral water from Ganymede whose effects are like those of the mythical Fountain of Youth.”

“You mean clithni, as the stuff is called by the Ganymedians. It is a clear, emerald liquid, rising in lofty geysers from the craters of quiescent volcanoes. Scientists believe that the drinking of clithni is the secret of the almost fabulous longevity of the Ganymedians; and they think that it may prove to be a similar elixir for humanity.”

“Some of the extraplanetary drugs haven’t been so beneficial to mankind, have they?“ queried Balcoth. “I seem to have heard of a Martian poison that has greatly facilitated the gentle art of murder. And I am told that mnophka, the Venerian narcotic, is far worse in its effects on the human system than is any terrestrial alkaloid.”

“Naturally, ” observed the doctor with philosophic calm, “many of these new chemical agents are capable of dire abuse. They share that liability with any number of our native drugs. Man, as ever, has the choice of good and evil… I suppose that the Martian poison you speak of is akpaloli, the juice of a common russet-yellow weed that grows in the oases of Mars. It is colorless, and without taste or odor. It kills almost instantly, leaving no trace, and imitating closely the symptoms of heart-disease. Undoubtedly many people have been made away with by means of a surreptitious drop of akpaloli in their food or medicine. But even akpaloli, if used in infinitesimal doses, is a very powerful stimulant, useful in cases of syncope, and serving, not infrequently, to re-animate victims of paralysis in a quite miraculous manner.

“Of course,” he went on, “there is an infinite lot still to be learned about many of these ultra-terrene substances. Their virtues have often been discovered quite by accident—and in some cases, the virtue is still to be discovered.

“For example, take mnophka, which you mentioned a little while ago. Though allied in a way, to the earth-narcotics, such as opium and hashish, it is of little use for anaesthetic or anodyne purposes. Its chief effects are an extraordinary acceleration of the time-sense, and a heightening and telescoping of all sensations, whether pleasurable or painful. The user seems to be living and moving at a furious whirlwind rate—even though he may in reality be lying quiescent on a couch. He exists in a headlong torrent of sense-impressions, and seems, in a few minutes, to undergo the experiences of years. The physical result is lamentable—a profound exhaustion, and an actual aging of the tissues, such as would ordinarily require the period of real time which the addict has “lived” through merely in his own illusion.

“There are some other drugs, comparatively little known, whose effects, if possible, are even more curious than those of mnophka. I don’t suppose you have ever heard of plutonium?”

“No, I haven’t,” admitted Balcoth. “Tell me about it.”

“I can do even better than that—I can show you some of the stuff, though it isn’t much to look at—merely a fine white powder.”
