Born from a buried pact. Forged in the abyss.

The Dagon Cult was not born as a religion.

It was born as an expedition.
As a military mission.
As a secret meant to be erased.

In 1911, a division of the German Schutztruppe was sent to Mesopotamia under the cover of an archaeological mission. Official reports spoke of Sumerian ruins, topographical surveys and ancient relics.

But the true objective was a place that appeared on no map.

A crater hidden among the sands.
A forgotten city.
A wound in the desert that local legends called The Mouth of the Gods.

In the oldest fragments, that name appears in a lost language:

Ngar-Zhaal’ur-Reth
The Mouth of the Dark Divinities, the Deep Whisper.

No one knows for certain what they found there.

The few surviving fragments speak of black glass, fused stone and an unnatural silence. They speak of men who returned changed. Of orders never recorded. Of documents that vanished. Of a presence that was not dead, yet not truly alive.

The expedition never really came back.

And yet, years later, something began to move along the coastlines.

The Call from the Depths

At first, there were only rumours.

Missing fishermen.
Abandoned coastal villages.
Strange chants in the fog.
Bodies returned by the sea with impossible marks upon their flesh.

Then came the masked men.

They wore ritual hoods, heavy gloves and golden masks. They spoke little. They marched like soldiers, but belonged to no known army.

Beneath their uniforms, the flesh was changing.

Their eyes became black and glossy.
Their skin took on a wet sheen.
Their hands deformed.
Their breathing grew slow, deep, almost marine.

It was not disease.
It was not injury.
It was transformation

From those first cells, the Dagon Cult was born: not a simple cult, but a secret army, grown in the shadows for decades through forbidden science, abyssal rituals and absolute devotion to a voice rising from the depths.

The Sunken Network

The Dagon Cult did not emerge from nothing.

For decades, it grew in silence, infiltrating the folds of the human world: aristocratic families, scientific societies, shipping companies, commercial harbours, esoteric circles, military castes and isolated coastal communities.

Some funded it out of greed.
Others out of fear.
Others because they had already heard the call of the sea.

In the great cities, its devotees opened foundations, laboratories and front companies. In coastal villages, entire communities slowly vanished into a new faith. In the halls of power, respectable men signed documents, diverted funds and made compromising reports disappear.

But the most dangerous part of the cult did not always wear ritual hoods and golden masks.

Sometimes it wore enemy uniforms.
Sometimes it signed military reports.
Sometimes it opened gates from within.
Sometimes it whispered orders through the radios of the surviving factions.

The cult learned never to show itself entirely.

One hand in the academies.
One in the ministries.
One in the shipyards.
One in the harbours.
One in the forgotten churches along the coast.

When the Dagon Cult finally emerged openly in 1949, many understood too late that it had not just been born.

It was already everywhere.

L’Abyss Doctor

Behind the birth of the Dagon Cult stands a single mind.

A man once known as Dr. Konrad Weiss: biologist, military neurologist, and student of accelerated evolution.

After the 1911 expedition, his name disappeared from official records. In later testimonies, he reappeared only as a figure impossible to classify: scientist, prophet, genetic architect, monster.

His followers call him The Abyss Doctor.

To him, humanity is not a species to be saved.
It is an incomplete form.

Fragile.
Limited.
Unable to survive the new biological order opening upon the Earth.

The Abyss Doctor does not seek an empire and does not dream of simple military conquest. His goal is far more radical: to rewrite terrestrial life, fusing human flesh, abyssal biology and alien knowledge into a new breed capable of inhabiting the world to come.

To achieve this design, he turned the lost division into a living laboratory.

The soldiers became test subjects, initiates and instruments.
The coastlines became harvesting grounds.
Isolated villages, selection fields.
Sunken temples, ritual chambers.
The creatures of the abyss, sacred material for a new evolution.

But at the blackest heart of this project lies a truth few dare to speak.

The Abyss Doctor believes he can use the forces of Dagon.
He believes he can summon the Deep Ones, control the Kaiju, bend the cult and turn the abyss into a scientific instrument.

And perhaps, for now, he can.

But Dagon watches from the bottom of the sea.

He lets the Doctor open the gates.
He lets him build the army.
He lets him awaken what only the cult can call forth.

Because every rite, every mutation and every creature unleashed brings the world closer to the moment when Dagon will reclaim what belongs to him

The Doctor thinks he controls the abyss.
The abyss allows him to believe it.

The Army of the Abyss

By 1949, the Dagon Cult has emerged openly.

The contaminated coastlines have become its sanctuaries.
The drowned harbours, its fortresses.
The ruins along the sea, its harvesting grounds.

Its soldiers do not fight like ordinary men. They advance through fog, brackish water and the wreckage of the old war, armed with modified rifles, ritual weapons and unstable technologies no regular army would dare to use.

Beside them march priests, cult sisters, hybrids and amphibious creatures from the abyss.

Some still retain a human shape.
Others have already become something else.

Behind every assault, every landing, every fallen village, the same promise is repeated:

flesh can be rewritten.
the Earth can be drowned.
man can become something else.

Flesh, Metal and Faith

For the Dagon Cult, there is no separation between war and ritual.

Every weapon is a relic.
Every vehicle is a mobile altar.
Every mutation is a sign of election.

Old armoured vehicles from the war are recovered, rebuilt and consecrated. Amphibious sleds cut across beaches and marshes like mechanical predators. Heavy tanks rise from the water, glowing with green light, their armour covered in symbols, masks and idols of the deep.

Even metal, within the Dagon Cult, seems infected by faith.

The machines do not simply advance.
They resurface.

The Children of the Black Sea

No one truly knows how many beings serve the Dagon Cult.

Some are mutated soldiers.
Others are hybrids born from experiments and rituals.
Others were never human at all.

Among them, the most feared are the Deep Ones: massive, ancient and ferocious amphibious creatures used as living heavy infantry.

When a Deep One appears on the battlefield, the rhythm of the fight changes.

It does not occupy the ground.
It breaks it.

Its hands tear down walls, its claws open armour, its body regenerates wounds that would kill any man. For the soldiers of other factions, its arrival is often the first sign that a coastline is already lost.

And in the depths, they say, there are even greater forms.

No one has seen them whole.
But some dream of them.

The Final Flood

The Dagon Cult does not seek only military victories.

It does not simply want to occupy cities or conquer territories.

It wants to prepare the world for a new era.

Its priests speak of the Final Flood: not a tide of water, but the total transformation of Earth. A tide of mutated flesh, shared consciousness and abyssal life destined to erase what remains of modern man.

For the Abyss Doctor, the Final Flood is the culmination of his work: proof that humanity can be rewritten, improved and made compatible with the new world.

For Dagon, however, it may be something else.

Not an experiment.
Not guided evolution.
Not a new race designed by a scientist.

But the return of his dominion.

The coastlines are only the beginning.
The tides are changing.
And on windless nights, those who live near the sea swear they can hear something breathing beneath the waves.

Descend into the Abyss

The first wave has emerged.

Cultists, hybrids, priests and Deep Ones march from the contaminated coastlines toward the ruins of the world.

The war for Earth has begun.
But for the Dagon Cult, it is not war.

It is birth.
