“We came to stop sabotage. We found Hell instead.”
— Anonymous Royal Navy officer’s log entry, 19xx
In late 19xx, British Naval Intelligence received credible warnings of a planned sabotage operation targeting a major White Star Line vessel. The intelligence came through multiple channels and was backed by influential and wealthy benefactors who had both the means and the motive to protect their interests in transoceanic shipping. The reports spoke of deliberate interference with the ship’s engines and navigation systems, possibly for financial gain, insurance fraud, or political disruption.
The Admiralty responded with measured caution. A small, professional detachment of Royal Navy ratings and officers was assembled. They were regular personnel with experience in shipboard security, damage control, and boarding actions — not special forces, not Marines.
To maintain operational secrecy, the detachment did not board in Southampton. Instead, they transferred quietly from a Royal Navy escort vessel that rendezvoused with the Olympic several days into the Pacific leg of the voyage. Officially, they were listed as additional communications specialists and security liaisons assisting with sensitive diplomatic mail and high-profile passengers.
Their orders were straightforward:
Protect the ship and its passengers from any act of sabotage.
Secure the bridge and vital engineering spaces if trouble arose.
Re-establish contact with Royal Navy assets if the ship was compromised.
The naval detachment arrived expecting conventional trouble — perhaps disgruntled crew, rival shipping interests, or political agitators.
What they found was far beyond anything they had been prepared for.
By the time they reached the lower decks, the sabotage had already been triggered. The ship had come to a dead stop directly over Point Nemo. An unnatural, iridescent fog had rolled in, swallowing visibility and interfering with instruments.
But the real horror was only just beginning.
What they encountered below decks was not ordinary saboteurs. The lower engineering spaces, coal bunkers, and boiler rooms had become a nightmarish fungal hive. Mi-Go — fungoid beings from the outer voids — had seeded the area with a hyper-aggressive cordyceps plague. Crew members and cultists alike were being rapidly transformed into blighted thralls: fungal stalks erupting from eyes, mouths, and chests, bodies jerking like puppets as they spread spores and harvested brains with cold efficiency.
The naval personnel who descended into the bowels of the ship were met with a scene of pure madness: former shipmates now crawling with living mycelium, moving in unnatural coordination, exhaling clouds of spores that turned the air into a choking haze.
The middle decks have fallen under the control of the Esoteric Order of the Abyss — human cultists performing ritualistic sacrifices and carving geometric sigils into bulkheads in preparation for awakening their sleeping god.
The upper decks and open areas are being overrun by Deep Ones — ancient, fish-like servants of the same entity — who have boarded from the black water below to stop the human cult and claim the awakening for themselves.
The naval detachment is now caught in the middle of a three-way war:
Fighting blighted, fungal-infected thralls in the lower decks
Hearing reports of cultists conducting rituals in the public rooms
Receiving frantic messages about Deep Ones swarming the upper decks and lifeboat areas
Their primary objective remains the same: restart the engines and boilers, move the ship out of the fog, and re-establish contact with Royal Navy rescue vessels. But with every passing hour, the situation grows more hopeless. The sailors and officers who descended into the bowels of the ship now fight not just for the vessel, but for any chance that someone — anyone — might survive the night.
They came expecting sabotage.
They found a war between gods and the mortals who dare to claim them.
