Date: November 12th, 1224
Location: The Port of Lübeck, Baltic Sea
The Baltic was a sea of iron and ice, a grey expanse that swallowed the sun by mid-afternoon. In the bustling port of Lübeck, the hub of the Hanseatic League, the air was sharp with the scent of pine tar and salted herring. But beneath the familiar odors of commerce, Artois the Younger smelled something that made the brine in his veins turn to slush: Desiccated Rot.
For months, rumors had trickled down the coast of "Ghost Ships"—merchant cogs found drifting with their sails in tatters, their crews missing, and their hulls coated in a strange, bioluminescent barnacle. The League called it a curse of the Vikings. Artois knew it was the Hydro-Vile Strain.
The Vilevine had conquered the desert, the forest, and the air. Now, it had taken the Water.
The Anatomy of the Brine-Eater
Artois stood on the frozen pier, his amber lens focused on the St. Jude, a cog that had been towed into the harbor after being found adrift off the coast of Denmark. The ship was a nightmare of biological overgrowth. The wood of the hull was no longer oak; it had been overwritten by a grey, coral-like substance that pulsed with a faint, rhythmic violet light.
The Hydro-Vile Strain did not kill its hosts immediately. It was a Transmuter. It entered the crew through the ship's water barrels. Once ingested, the resin didn't seek the lungs or the brain; it sought the Skeleton. It replaced the calcium in the bones with a flexible, water-conductive fiber that allowed the host to survive the crushing depths and the freezing cold of the Baltic.
The crew of the St. Jude hadn't disappeared. They had simply... changed. They were no longer men of the land. They had become the Drowned Vanguard, creatures capable of living beneath the waves, tethered to the "Coral-Hearts" growing on the underside of the ships.
The Infiltration of the Frozen Cog
Artois boarded the St. Jude at midnight. The deck was slick with a translucent slime that smelled of deep-sea kelp and copper. As he moved toward the hold, he saw them: the crew.
They were fused to the masts and the rigging. Their skin was the color of a shark's belly, and their eyes were large, lidless orbs of solid black. They didn't breathe air; they "pulsed," their ribs expanding and contracting to filter the moisture from the freezing fog.
"The Salt-Walker comes to the deep," a voice gurgled. It didn't come from a mouth, but from a series of slit-like gills on the captain's neck.
Captain Hrolf, once a proud merchant of the League, was now a centerpiece of the ship's transformation. His lower body had merged with the mainmast, his nervous system extending into the very timber of the ship. He was the Vessel-Heart.
"You cannot salt the ocean, Artois," Hrolf hissed, his voice a series of wet, percussive clicks. "The Baltic is our womb. Every ship that sails these waters is a host. We are building a reef that will stretch from Novgorod to London. A forest of coral that will choke your ports and drown your world."
The Duel of the Drowned
Artois didn't use fire. In the damp, salt-heavy air of the Baltic, fire was a weak ally. Instead, he used Pressure.
He carried a "Brine-Lance"—a pneumatic tube filled with the concentrated, freezing vitriol of the Dead Sea, kept at a pressure that could pierce the hide of a whale. When he triggered the release, the lance emitted a jet of liquid salt so cold it turned the Hydro-Vile's aquatic resin into brittle glass.
The Drowned Vanguard lunged from the rigging. They moved with a terrifying, fluid grace, their webbed hands ending in obsidian-tipped claws. Artois spun, his lance hissing as it carved white, frozen lines through the grey flesh of the attackers. Where the vitriol hit, the aquatic fibers shattered, the "Aqua-Resin" turning into useless, salty slush.
"You are a creature of the desert!" Hrolf roared, the mast of the ship groaning as he pulled against his moorings. "You have no power in the cold!"
Hrolf released a spray of "Bioluminescent Ink"—a cloud of spores that glowed with a blinding violet light, designed to disorient and paralyze.
Artois didn't blink. He closed his eyes and relied on his Noir-Sense—the ability to feel the movement of Sap through the air. He felt the Captain's "Heart-Pulse" located deep within the mast.
He didn't strike the Captain. He struck the Hull.
The Sinking of the St. Jude
Artois had planted a series of Salt-Cores along the ship's keel—charges of concentrated Engedi minerals designed to trigger a "Structural Rejection" in the Hydro-Vile coral.
"The sea will take you, Hrolf," Artois whispered. "But it will take you as salt, not as silk."
He detonated the cores.
The reaction was a violent, subterranean thud. The grey coral coating the hull didn't explode; it Crystallized. The flexible, water-conductive fibers turned into rigid, brittle salt. Under the pressure of the Baltic, the ship's structural integrity vanished. The St. Jude didn't just sink; it Disintegrated.
As the ship began to plunge into the icy depths, Artois leaped for the pier. Behind him, the violet glow of the St. Jude was extinguished by a massive cloud of white, salty bubbles. The "Vessel-Heart" shrieked as the freezing brine of the sea turned into a caustic poison, the salt-saturated water tearing through the Hydro-Vile's gills.
The Journal of the Frozen Sea
Artois sat on the pier, his coat frozen stiff, his hands white with frostbite. He watched the bubbles dissipate. He knew he hadn't cleared the Baltic. There were hundreds of these ships, a silent fleet of the Drowned waiting for the spring thaw to begin their "Great Submersion."
He opened his journal, the pages now so encrusted with salt they were as hard as slate.
Entry 9: The Vilevine has conquered the cold. The Hydro-Vile strain is a master of the dark and the deep. It has turned the sea—our greatest trade route—into a highway for the harvest.
I destroyed the St. Jude, but the 'Reef' is still growing. I can hear the clicking of the Drowned in the waves. They are patient. They are many.
My body is failing. The 'Salt-Stress' is no longer just a burden; it is a transformation. My heart beats once every minute. My blood is a slurry of minerals. Silas... I am becoming the statue Balian was. I must find the last Hub. I must find the Mother-Reef before the Baltic becomes a violet grave.
The Hanseatic League is dead. They just don't know it yet. They think they are trading furs and wax. They are trading the end of the world.
