Reasons to like Lovecraft: Y’golonac (the Defiler)

Y’golonac – Great Old One

If you’re a fan of H.P.Lovecraft (and those authors who have added to his body of work) you may recognise and hopefully enjoy seeing this. If you’re unaware of H.P.Lovecraft, then peel the rime off your eyeballs and get into this world of ultimate, sanity-blasting cosmic horror…

Beyond a gulf in the subterranean night a passage leads to a wall of massive bricks, and beyond the wall rises Y’golonac to be served by the tattered eyeless figures of the dark. Long has he slept beyond the wall, and those which crawl over the bricks scuttle across his body never knowing it to be Y’golonac; but when his name is spoken or read he comes forth to be worshipped or to feed and take on the shape and soul of those he feeds upon. For those who read of evil and search for its form within their minds call forth evil, and so may Y’golonac return to walk among men . . .

Revelations of Glaaki, Volume 12


Y’GOLONAC first emerged into public awareness from the nebulous murk of mystery and chaos that is the Cthulhu Mythos, through the legendary British horror writer Ramsey Campbell (Cold Print, 1969).

Now lots of things in the Mythos can be defined in terms of depravity and atrocity; Llloiger worship and the mocking machinations of Nyarlathotep might initially spring to mind, but acolytes of Lloiger inflict shocking injuries on victims for a purpose, and typically suffer terrible personal mutilation for failing in that purpose. And Nyarlathotep, there is often the glimmer of hope in the horror he unwinds like a slipknot noose around the neck and limbs of the unwary – only to vanish as the ultimate trap jerks into a deadly denouement.

Y’golonac’s behavior is driven by the basest form of primal Evil – with a capital ‘E’.  Similar to demonic possession, in that the entity wants to wallow in an orgy of extreme sensory input: savage violence carried out for the wild thrill of it.  Torture to create suffering – pain, subjugation and absolute domination – for no other reason than to glut on the energy released in the quiver of nerve endings and pulsing emotions.  Bestial acts based on exploring perversion.  Yet  Y’golonac takes these things to a whole new order of magnitude.

Depravity and atrocity, these are the hallmarks of the Great Old One Y’golonac


Even the minions of the Cthulhu Mythos dare not utter the sounds that define the name, Y’golonac
For fear of conjuring the great defiler from its abstracted prison of bricks in some nameless place
Once more to walk amongst those who have the capacity for sanity and rational thought
With vile possession it can take any host
With the singular hunger to rape, consume and destroy all that it covets most – but never sought.

—Fragment from the Ceretautilus Scripts, English translation by Gertrude von Grimmen (from Medieval French version 1667)


In all of this there is something very human about Y’golonac. But do not be mistaken in thinking there is anything remotely human about it.  It thrives on invading sentient thought, feasting on the memories and motives and urges of anything capable of having a conscious or subconscious thought.  It exists to ruin anything it so encounters, from human, to non-human races, through to less gods themselves.  It is possibly why Y’golonac has been locked away so voraciously, beyond comprehension and beyond any known point in space, time or the outer chaos.

Yet evil minds seek out evil texts, and within certain pages are the words that are capable of blurring the membranous boundary between reality and this monstrous cosmic horror.  It is the classic Candyman principle that has pervaded since warlocks bound demons into ancient books. Say the name and it may come.

If you have Evil in your heart, and you read the name Y’golonac from the right texts, then a channel is opened immediately to the place where Y’golonac exists, incarcerated, waiting with patient fury, for moments such as these to walk abroad and wreak havoc.

For humans, its arrival is disembodied, a presence, a voice, until it either kills or takes possession of the maniac who has summoned it.  Possession results in a grotesque transformation: the body swells, the head caves in and melts away, and a viciously fanged maw opens up in the palm of each hand – note, anybody bitten by these hand-mouths finds the wounds never heal, and they go on to suffer terrible nightmares and attacks of anxiety thereafter.  Game masters and story-tellers should also consider the nature and use of Y’golonac’s sexual organs.

In its purest form, there is no negotiating with Y’golonac, no appealing to a thread of human vanity (many Great Old Ones share human traits because humans by their origin – crawling out of the slime pits to be play things of the Elder Things) , and absolutely no mercy.  Y’golonac does not hesitate to think or consider… it is swift, brutal and relentless.

Cults and Worship

Very rare mainly due to the fact  Y’golonac kills most folks who summon it. Those not brutalised, killed and eaten, are forced to serve it in the most barbaric fashion. Encountering a worshiper of Y’golonac is only going to mean very bad  things are going to happen.

Further Reading

The Quotidian Traffic: Andy Alkaev has put together  a fantastic comparison with “similar” monsters not necessarily of the Cthulhu Mythos but parallel pantheons of physical perversity.

Mythos Fiction in paperback and Kindle:

Living in Flames a science fiction dark fantasy novel set in Bristol expanding the cosmic horror of the Cthulhu Mythos by David J Rodger

Available in paperback and Kindle format

Living in Flames

By David J Rodger


A fast-paced British sci-fi horror in the very near future




“Atmospheric and Creepy” – The Guardian on The Black Lake


“…the best Sci-Fi horror I’ve read in ten years” – Floyd Hayes, Creative Director of World’s Fastest Agency on Dog Eat Dog


David J Rodger’s successful blend of gritty near future fiction and blunt, remorseless horror, continues with Living in Flames – following on the back of the smash hits Dante’s Fool; Iron Man Project, Edge and God Seed. All five books are separate and unrelated stories that occupy a single shared universe.

Living in Flames carries a chaotic mix of big characters through the meat-grinder fury of the Cthulhu Mythos. This is H.P.Lovecraft for the 21st century.  If you enjoy the idea of an unconventional terror that flows down through the bloodlines of ancestry then this book will provide the required spine-convulsing chill.

The ex-marine, selling drugs for a crime-syndicate psychopath whilst desperately seeking any way out. The deal-maker, running from a violent past and who just needs one final big score before retiring to sunshine and sangria. The once privileged daughter, rejected by her wealthy merchant family as a child, now grown-up and struggling to come to terms with the shocking legacy of her heritage. And a multitude of vibrant, secondary characters. These are the people who fight to survive as an ancient abomination surges out of history to flow into the dark spaces beneath the city.

This is a fast-moving, intelligent horror story that ends in absolute carnage.
