Cthulhu Mythos Cosmology and Gods

Hypnos

Much of the relevant information for Hypnos is able to be found in the cosmology explanation here. So, consider this section as a continuation of sorts of the section titled "Beyond the First Gate". The narrator, forced awake by their inability to breach the final obstacle, waits for Hypnos to wake up as well. However, the reaction Hypnos has to what he saw beyond that barrier traumatizes the narrator, with Hypnos himself having been drawn to permanent insanity.

"I had, I felt, been halted by a barrier which my friend and leader had successfully passed. Struggling anew, I came to the end of the drug-dream and opened my physical eyes to the tower studio in whose opposite corner reclined the pallid and still unconscious form of my fellow-dreamer, weirdly haggard and wildly beautiful as the moon shed gold-green light on his marble features. Then, after a short interval, the form in the corner stirred; and may pitying heaven keep from my sight and sound another thing like that which took place before me. I cannot tell you how he shrieked, or what vistas of unvisitable hells gleamed for a second in black eyes crazed with fright. I can only say that I fainted, and did not stir till he himself recovered and shook me in his phrensy for someone to keep away the horror and desolation."

Long after this, when the protagonists agree never to sleep again and go out of their way to accomplish this, there comes a point where they can't do it anymore, and eventually, as Hypnos falls asleep, the protagonist senses that something is about to happen.

"The tension of my vigil became oppressive, and a wild train of trivial impressions and associations thronged through my almost unhinged mind. I heard a clock strike somewhere—not ours, for that was not a striking clock—and my morbid fancy found in this a new starting-point for idle wanderings. Clocks—time—space—infinity—and then my fancy reverted to the local as I reflected that even now, beyond the roof and the fog and the rain and the atmosphere, Corona Borealis was rising in the northeast. Corona Borealis, which my friend had appeared to dread, and whose scintillant semicircle of stars must even now be glowing unseen through the measureless abysses of aether. All at once my feverishly sensitive ears seemed to detect a new and wholly distinct component in the soft medley of drug-magnified sounds—a low and damnably insistent whine from very far away; droning, clamouring, mocking, calling, from the northeast."

Take note of the bolded sentence above. It sounds awfully familiar, doesn't it?

"And through this revolting graveyard of the universe the muffled, maddening beating of drums, and thin, monotonous whine of blasphemous flutes from inconceivable, unlighted chambers beyond Time; the detestable pounding and piping whereunto dance slowly, awkwardly, and absurdly the gigantic, tenebrous ultimate gods—the blind, voiceless, mindless gargoyles whose soul is Nyarlathotep."

"There were, in such voyages, incalculable local dangers; as well as that shocking final peril which gibbers unmentionably outside the ordered universe, where no dreams reach; that last amorphous blight of nethermost confusion which blasphemes and bubbles at the centre of all infinity—the boundless daemon-sultan Azathoth, whose name no lips dare speak aloud, and who gnaws hungrily in inconceivable, unlighted chambers beyond time amidst the muffled, maddening beating of vile drums and the thin, monotonous whine of accursed flutes; to which detestable pounding and piping dance slowly, awkwardly, and absurdly the gigantic ultimate gods, the blind, voiceless, tenebrous, mindless Other Gods whose soul and messenger is the crawling chaos Nyarlathotep."

That's right- the realm Hypnos found himself in is none other than the Outer Void. There are more quotes of this nature, but I think these two are enough. If you aren't convinced, let's take a look at another excerpt from this story:

"Especially was he afraid to be out of doors alone when the stars were shining, and if forced to this condition he would often glance furtively at the sky as if hunted by some monstrous thing therein. He did not always glance at the same place in the sky—it seemed to be a different place at different times. On spring evenings it would be low in the northeast. In the summer it would be nearly overhead. In the autumn it would be in the northwest. In winter it would be in the east, but mostly if in the small hours of morning. Midwinter evenings seemed least dreadful to him. Only after two years did I connect this fear with anything in particular; but then I began to see that he must be looking at a special spot on the celestial vault whose position at different times corresponded to the direction of his glance—a spot roughly marked by the constellation Corona Borealis."

Now let's compare it to some quotes from The Dreams in the Witch House, where the protagonist (Walter Gilman) is being influenced and toyed with by Nyarlathotep:

"He was good for nothing that morning, and stayed away from all his classes. Some unknown attraction was pulling his eyes in a seemingly irrelevant direction, for he could not help staring at a certain vacant spot on the floor. As the day advanced the focus of his unseeing eyes changed position, and by noon he had conquered the impulse to stare at vacancy. About two o'clock he went out for lunch, and as he threaded the narrow lanes of the city he found himself turning always to the southeast. Only an effort halted him at a cafeteria in Church Street, and after the meal he felt the unknown pull still more strongly."

"The southeastward pull still held, and only with tremendous resolution could Gilman drag himself into the old house and up the rickety stairs. For hours he sat silent and aimless, with his eyes shifting gradually westward. About six o'clock his sharpened ears caught the whining prayers of Joe Mazurewicz two floors below, and in desperation he seized his hat and walked out into the sunset-golden streets, letting the now directly southward pull carry him where it might. An hour later darkness found him in the open fields beyond Hangman's Brook, with the glimmering spring stars shining ahead. The urge to walk was gradually changing to an urge to leap mystically into space, and suddenly he realised just where the source of the pull lay."

"It was in the sky. A definite point among the stars had a claim on him and was calling him. Apparently it was a point somewhere between Hydra and Argo Navis, and he knew that he had been urged toward it ever since he had awaked soon after dawn. In the morning it had been underfoot; afternoon found it rising in the southeast, and now it was roughly south but wheeling toward the west. What was the meaning of this new thing? Was he going mad? How long would it last? Again mustering his resolution, Gilman turned and dragged himself back to the sinister old house."

"Gilman awakened in his bed, drenched by a cold perspiration and with a smarting sensation in his face, hands, and feet. Springing to the floor, he washed and dressed in frantic haste, as if it were necessary for him to get out of the house as quickly as possible. He did not know where he wished to go, but felt that once more he would have to sacrifice his classes. The odd pull toward that spot in the sky between Hydra and Argo had abated, but another of even greater strength had taken its place. Now he felt that he must go north—infinitely north. He dreaded to cross the bridge that gave a view of the desolate island in the Miskatonic, so went over the Peabody Avenue bridge. Very often he stumbled, for his eyes and ears were chained to an extremely lofty point in the blank blue sky."

So yeah, it is all but directly stated that Hypnos was driven insane by the Outer Void and the Other Gods within.
