And, without further adieu, I present Michal 'Majqello' Knapik's designs for it.
THE BLOOD GARGOYLE AND THE BLOOD SPHINXES
Above a great altar in the Temple where Nyarlathotep reigns, there is a gargoyle depicting the Haunter of the Dark. It is littered with the skulls of sacrificial offerings and vomits blood into a pool of sacrifice.
Lining the pathway up to the altar are sphinx-like gargoyles that depict Hunting Horrors (see "CREATURES"). Their three-lobed eyes, like the gargoyle above, are aflame and serve as torches. These daemons also puke blood into a stream that flows into pools of sacrifice and occasionally move. These represent how blood flows from every corner of space and time to appease the gnawing hunger of Nyarlathotep.
"Hunting Horror Blood Gargoyle Sphinx (could be title of a death metal song)"
The Hunting Horror off which the sphinx-gargoyles are based. It is supposedly related to the Haunter of the Dark.
Amorphous flute players accompany the Crawling Chaos at his altar: the Moon Beasts.
White, slippery and hideous are these creatures. Instead of faces they have short pink tentacles like those of a sea anemone, which writhe constantly while maddening notes erupt from their flutes.
More of an ornamental symbol throughout the temple, this is inspired by the traditional Wadjet Cobra: thusly, the Nyarlathotep Wadjet Cobra.
FORMS OF NYARLATHOTEP
The hooved Black Man, an incarnation of Satan (from The Dreams in the Witch House).
The Black Pharaoh Nephren-Ka, with tentacled imagery in his dress (from Nyarlathotep - a prose poem and a poem; The Dream-Quest of Unknown Kadath; and The Haunter of the Dark).
The Mad Faceless God (from The Rats in the Walls): an Azathoth-like shape that howls at Earth's center. Note the rats and the Moon Beast flute players.
The Haunter of the Dark (from The Haunter of the Dark). It is vaguely shaped as it cannot exist in light. The Three-Lobed Burning Eye can be seen on its "head".
Note: there will be another form of Nyarlathotep animated: the Howler in the Dark/Red Tentacle/God of the Bloody Tongue. KingOvRats has not drawn this.
Nyarlathotep is the Taker of Life and the Master of Death. The two Ankhs represent these. On the left is the inverted Ankh of Death, made of bones and corpses. On the right is the upright Ankh of Life, made of writhing tentacles.
The Eye of Nyarlathotep is a decoration around the Temple. It is designed like the Eye of Horus.
The Three-Lobed Burning Eye is that of the Haunter of the Dark. It burns on the altar, flaming, and evil. It is inspired by the "All-Seeing Eye" - a definitive symbol of the Illuminati.
THE POOLS OF SACRIFICE AND THE IDOLS OF BONE
The rivers of blood that the Hunting Horror gargoyles/sphinxes puke flow into pools of sacrifice. In the pools are isles - platforms - made of bones and corpses. On the isles there is a bone idol of Nyarlathotep.
"Bone statue of Nyarlathotep in pool of BLOOD"
Well! That's the Temple of the Crawling Chaos for you! While Lovecraft didn't create this (and I'm not quite sure if he had this in mind when creating Nyarlathotep), I like it and I hope he would've liked it too.
I'll close off with a quote from the script: wherein Gilman reads a passage about Nyarlathotep in the Necronomicon. While it is of my own writing and is inspired by a certain passage from The Dunwich Horror which the true Lovecraft fan will know, the lore of the blood flowing towards Nyarlathotep from all corners of the universe and the Ankhs were completely based on Michal's ideas. Goodnight, everybody.
Nyarlathotep reigns beside Azathoth at the Throne of Chaos, and at the great Temple of the Crawling Chaos deep in space. His Sigils be the greatest of all, for he alone knoweth the secrets and powers of Life and Death. There are two Ankhs, one upright, the other, inverted, that represent the powers of the Crawling Chaos. The upright Ankh represents Life: constructed of tentacles, writhing and alive: the endless vital energies of Nyarlathotep symbolized, the heads of the Hydra ever growing. The inverted Ankh is one of Death, built of the bones of thousands and the screams of millions. The entire universe is in his grip. Blood from every corner of space and time floweth to him for his sake…the deaths of every single creature poured into a pool of sacrifice. He is the apocalypse, and when the time has come for the universe, he shall stand in that revolting graveyard and he shall laugh. He is Hell embodied into one being. Iä! Shub-Niggurath! The Black Goat of the Woods with a Thousand Young! Thou shalt fear the Crawling Chaos, for he watches through the angles of reality. He is the Taker of Life and the Master of Death.
