"The Deep Ones are the tide. We are the hand that commands it. When R'lyeh rises, humanity shall not kneel — we shall rule." — High Priestess Constance Harrow, 1919
The Esoteric Order of the Abyss was founded in 1897 in a fog-shrouded manor on the outskirts of Innsmouth, Massachusetts. Its creator was Dr. Ambrose Langford, a once-respected professor of comparative mythology at Miskatonic University. Langford had spent years chasing forbidden texts across Europe and New England. In the summer of 1896, during a private expedition to the ruins of an abandoned church near Innsmouth, he discovered a water-stained, incomplete copy of the Pnakotic Manuscripts. The final intact page contained a prophecy that consumed him: the Great Old One Cthulhu could be awakened not by the Deep Ones alone, but by a meticulously orchestrated human ritual performed aboard a great vessel positioned directly above R'lyeh during the celestial alignment of 1920.
Langford rejected the idea that humanity must remain passive servants to the Deep Ones. He believed that if mortals could prove their worth through calculated sacrifice and perfect geometric ritual, Cthulhu would elevate humanity — specifically the Order — as the new ruling caste when R'lyeh rose. This philosophy became the Order's core doctrine and the source of its eternal conflict with the Deep Ones.
The Order operates as a highly compartmentalized secret society with three concentric circles:
Public-facing members embedded in high society: industrialists, politicians, artists, and academics who provide funding, influence, and cover.
Mid-level operatives who carry out rituals, sabotage, and recruitment.
Never more than thirteen members, who alone know the complete ritual geometry required to awaken Cthulhu.
By 1910 the Order had successfully infiltrated the highest levels of British and American power structures:

These connections gave the Order access to passenger manifests, crew rosters, and detailed engineering blueprints of the Olympic years in advance. The sabotage of Boiler Room 5, the placement of ritual anchors on every major deck, and the smuggling of the Abyssal Codex were executed with surgical precision.

The Deep Ones regard the Order as blasphemous upstarts who would steal the glory that belongs solely to their ancient bloodlines. For the Deep Ones, the awakening of Cthulhu is a divine right earned over millennia of service. The human cult's plan to perform the final ritual themselves is considered the ultimate insult.
This ideological and racial conflict has turned the Olympic into a floating battlefield. Deep Ones board from the sea to disrupt the ritual, while the Order deploys human fanaticism as weapons to fight back. Both factions are willing to slaughter every passenger and crew member aboard if it secures their god's favor.
The Order spent more than two decades ensuring the Olympic would be the perfect vessel. They infiltrated the White Star Line's engineering and navigation departments, planted ritual anchors on every major deck, and smuggled the Abyssal Codex aboard in pieces hidden inside passenger luggage. The goal is elegant yet apocalyptic: when the celestial alignment is perfect, the ship must serve as both altar and beacon. Every soul aboard is to be offered in a single night of calculated horror. If the ritual succeeds, Cthulhu will rise and recognize humanity — specifically the Order — as the new chosen people.
The Deep Ones will do everything in their power to stop it.
You are now aboard this floating temple of madness, caught between two factions who both claim divine right over the same sleeping god.
The game has begun.
The Order of the Abyss: Cult Hierarchy
The RMS Olympic isn’t just a ship to the cultists; it is a floating, three-tiered temple designed to power the Rite of the Sunken God.
The Rite requires massive amounts of psychic energy. The cultists are divided into three distinct tiers to generate this energy, feeding it down to the Voice (Martin Bell) in The Void Beneath.
Operatives: Angus Green, Ashley Thomson, Rufus Thomas, Jaden Lewis
This is the visceral, bloody foundation of the ritual. These lower-level fanatics have snapped completely, turning the Third Class areas and kitchens into a slaughterhouse. Their job is to keep the lower decks saturated in blood and primal panic, which acts as the raw "fuel" for the chanting below.
Operatives: Maximilian Cunningham, Peter Mitchell, Theo Turner, Gérald Pernet
The elite passengers require a different touch. These cultists are deceivers. Their job is to sow paranoia, isolate targets, spread rumors, and gaslight the survivors. They refine the raw fuel into pure psychological dread.
Operatives: Brother Caelan Shaw, Lionel Dimont
Highly tactical operators. While the chaotic harvest takes place, they ensure no one accidentally ruins the plan. They keep the ship dead in the water and surgically eliminate anyone (like investigators) who gets too close to the truth. They do not monologue; they execute.
At the top of the hierarchy sit three masterminds, each serving a vital role. For investigators, their true identities must remain hidden until the absolute last moment.
Martin Bell (The Key): The Voice of the ritual. He endlessly chants in isolation to unlock the door to R'lyeh. He provides real help to investigators early on to gain trust and steer them away.
Aubree Woods (The Shield): The tactical commander of the upper decks. Operating under the flawless guise of a helpful, composed socialite, she manipulates the survivors and directs the Tier 2 Lurers, ensuring investigators look in the wrong direction.
Lacie Hill (The Vessel): The highest-level cultist on the ship. She plays the role of a helpless, traumatized victim in a torn dress. In reality, she is in a cocoon phase, soaking in the psychic horror to become the host for the avatar of the Sunken God. She weaponizes empathy to infiltrate investigator safe rooms.
The ritual is generating so much cosmic noise that it has attracted uninvited guests, turning the ship into a chaotic, multi-faction ecosystem. The Order thinks they are in control—they are terribly wrong.
Ybryxu (The True Believer - Deep One): A Deep One whose goals align with the cult, but she views human cultists as pathetic, zealous livestock. She will not take orders from Martin or Aubree and may actively kill cultists who annoy or inconvenience her.
Elias Crowe (The Parasite - Fractured Veil): A rival cultist hijacking their cosmic Wi-Fi. He is letting the Order do the hard work of thinning reality so he can steal the focal point and open a gate for Yog-Sothoth instead. He might even help investigators stop Martin Bell just to seize control of the ritual.
Sir Zachariah Lowe (The Consequence - Hound of Tindalos): The immense magical energy of the ritual warped spacetime, creating an angle for this temporal apex predator to enter. It hunts everyone—cultist and passenger alike. The cultists are terrified of him because they cannot control him.
Elisa Young (The Contagion - Mi-Go Blight): The Mi-Go (ancient rivals of Cthulhu's spawn) sabotaged the engines to stop the ship. Elisa, a lower-level cultist, got caught in a Mi-Go spore trap. Her resulting infection injects frantic doubt into the lower ranks, as she realizes her god won't save her from alien fungus.
