More horrors for The Cthulhu Hack.
According to these scraps of information, the basis of the fear was a horrible elder race of half-polypous, utterly alien entities which had come through space from immeasurably distant universes and had dominated the earth and three other solar planets about six hundred million years ago. They were only partly material—as we understand matter—and their type of consciousness and media of perception differed wholly from those of terrestrial organisms. For example, their senses did not include that of sight; their mental world being a strange, non-visual pattern of impressions. They were, however, sufficiently material to use implements of normal matter when in cosmic areas containing it; and they required housing—albeit of a peculiar kind. Though their senses could penetrate all material barriers, their substance could not; and certain forms of electrical energy could wholly destroy them. They had the power of aërial motion despite the absence of wings or any other visible means of levitation. … Such was the fixed mood of horror that the very aspect of the creatures was left unmentioned—at no time was I able to gain a clear hint of what they looked like. There were veiled suggestions of a monstrous plasticity, and of temporary lapses of visibility, while other fragmentary whispers referred to their control and military use of great winds. Singular whistling noises, and colossal footprints made up of five circular toe-marks, seemed also to be associated with them. (The Shadow Out of Time by H. P. Lovecraft)

Formless Spawn of Tsathogghua
At any rate, when the men of K’n-yan went down into N’kai’s black abyss with their great atom-power searchlights they found living things—living things that oozed along stone channels and worshipped onyx and basalt images of Tsathoggua. But they were not toads like Tsathoggua himself. Far worse—they were amorphous lumps of viscous black slime that took temporary shapes for various purposes. The explorers of K’n-yan did not pause for detailed observations, and those who escaped alive sealed the passage leading from red-litten Yoth down into the gulfs of nether horror. Then all the images of Tsathoggua in the land of K’n-yan were dissolved into the ether by disintegrating rays, and the cult was abolished forever. (The Mound by H. P. Lovecraft and Zealia Bishop)

Hound of Tindalos
“They are lean and athirst!” he shrieked. “The Hounds of Tindalos!”
“Chalmers, shall I phone for a physician”
“A physician cannot help me now They are horrors of the soul, and yet”—he hid his face in his hands and groaned—”they are real, Frank. I saw them for a ghastly moment. For a moment I stood on the other side. I stood on the pale gray shores beyond time and space. In an awful light that was not light, in a silence that shrieked, I saw them.
“All the evil in the universe was concentrated in their lean, hungry bodies. Or had they bodies? I saw them only for a moment; I cannot be certain. But I heard them breathe. Indescribably for a moment I felt their breath upon my face. They turned toward me and I fled screaming. In a single moment I fled screaming through time. I fled down quintillions of years.” (The Hounds of Tindalos by Frank Belknap Long)
