(1934), Atlach-Nacha is the reluctant recipient of a human sacrifice given to it by the toad-god Tsathoggua. Atlach-Nacha resembles a huge spider with an almost-human face. It dwells within a huge cavern deep beneath Mount Voormithadreth, a mountain in the now vanished kingdom of Hyperborea in the Arctic. There it spins a gigantic web, bridging a massive chasm between the Dreamlands and the waking world. Some believe that when the web is complete, the end of the world will come, because it will create a permanent junction with the Dreamlands, allowing monsters to move freely into the waking world. Atlach-Nacha probably came to Earth from the planet Cykranosh (or Saturn as we know it today) with Tsathoggua. Because of its appearance, Atlach-Nacha is often referred to as the Spider-God(dess) and is believed to be the regent of all spiders. Furthermore, the giant, bloated purple spiders of Leng are thought to be its children and servitors. There is some disagreement about its gender. In Smith's original story, Atlach-Nacha is referred to as a male, but in later stories by other authors, it is implied to be a female. Rlim Shaikorth Rlim Shaikorth appears as a huge whitish worm with a gaping maw, and eyes made of dripping globules of blood, and is thus commonly known as the white worm. He travels on a gigantic iceberg called Yikilth, which it can guide across the ocean. In its colossal ice-citadel, the White Worm prowls the seas, blasting ships and inhabited land masses with extreme cold. Victims of the White Worm are frozen solid, their bodies appearing eerily white, and remain preternaturally cold—they will not melt nor warm even when exposed to fire.

Headless, without organs or members, it sloughed from its oozy sides, in a slow, ceaseless wave, the amoebic forms that were the archetypes of earthly life. Horrible it was, if there had been aught to apprehend the horror; and loathsome, if there had been any to feel loathing. About it, prone or tilted in the mire, there lay the mighty tablets of star-quarried stone that were writ with the inconceivable wisdom of the pre-mundane gods. —Clark Ashton Smith, Ubbo-Sathla Ubbo-Sathla ("The Unbegotten Source", "The Demiurge") is described as a huge
