The salt of Crete had scoured the surface of the Mediterranean, but it had not reached the deep, subterranean aquifers where the Vilevine's most resilient spores lay dormant. Following the collapse of the Minoan thalassocracy, the parasite underwent a period of deep-cycle hibernation, retreating into a state of "molecular mimicry." It realized that large-scale botanical structures like the Labyrinth were too vulnerable to the concentrated alchemies of the Salt-Born. To survive the rising tide of the Roman Empire, the Vine had to become microscopic. It had to move from the garden into the Aorta.
By the first century BCE, as Rome expanded its reach from the hills of Latium to the far corners of the known world, the Vilevine evolved into its most insidious form yet: the Aorta Strain. This was no longer a visible infection. It was a fluid-based parasite that lived entirely within the human circulatory system, mimicking the behavior of red blood cells.
The Blood of the Legions
The infection began at the fringes of the empire, in the humid forests of Germania and the marshes of Pannonia. Roman legionnaires, exhausted by endless marches and the "swamp fevers" of the north, began to report a strange new vigor after drinking from certain "sacred springs." These springs were, in reality, the exit points for the Vilevine's deep-root reservoirs.
The Aorta Strain did not create "Sap-Vampires" in the traditional sense. It created the Centurion-Integrated. These were men who could march for three days without sleep, whose wounds closed with a thick, resinous scab within minutes, and who possessed a terrifying, singular focus on the expansion of the Roman borders. To the generals in Rome, this was a gift from Mars. To the Vilevine, the Roman Legions were the perfect "vector."
The empire's greatest achievement—the Roman Road system—became the Vilevine's greatest asset. Every mile of stone laid by the legions was followed by a subterranean "shadow-root" that used the vibrations of the marching feet to navigate. The Vine was no longer trying to build a tower; it was building a Pulse-Network that mirrored the infrastructure of the greatest empire on earth.
The Anatomy of the Aorta Strain
Unlike previous versions, the Aorta Strain specialized in Hematological Overwrite. Once the spores entered the bloodstream, they began to dismantle the host's natural iron-processing organs. The spleen and liver were slowly converted into "Biomass Refineries," which turned oxygen into a hyper-volatile, violet-tinted sap.
The "Bloodlust" of this era was subtle but relentless. The integrated legionnaires developed an addiction to Hemic-Nitrates found in fresh human blood. They didn't need to drain a victim dry; they only needed a "communion"—a ritualistic tasting of the blood of the conquered. This fostered a culture of extreme brutality within the legions, as the soldiers' biological need for fresh iron drove them to seek constant conflict.
The Shadow Senate: Integration of the Elite
As the legions returned to Rome, the infection moved from the barracks to the Palatine Hill. The Vilevine understood that to control the body of Rome, it had to control its head. The Aorta Strain began to appear in the vintage wines of the aristocracy, much like the Liana Strain of old, but with a new twist: it carried a Memory-Parasite.
When a Senator was integrated, the Vine didn't just take his body; it began to "harvest" his political connections, his secrets, and his tactical knowledge. Rome became a "Shadow Empire," where the public laws were debated by men who were secretly nodes in a continental hive-mind. The emperor himself, Nero, was rumored to have "violet eyes" in the dark—a sign that his erratic behavior and thirst for blood were not madness, but the erratic pulses of a strained Aorta host.
The Resistance: The Catacomb-Alchemists
The "Rejection" in this era survived in the most unlikely of places: the Catacombs. A secret sect of Greek physicians, Egyptian mystics, and early Christian outcasts realized that the "Eternal City" was being hollowed out by a green rot. They were led by Galen of Pergamum—not the historical physician the world remembers, but a man who had discovered that the "Aorta Strain" had one fatal flaw: it was highly sensitive to Sulfur-Salts and Vitriol.
Galen and his followers practiced a form of "Blood-Purification." They realized that the only way to stop an Aorta-Integrated host was to induce a Systemic Calcification—to turn the host's own blood into a solid mineral sludge before the Vine could adapt.
"Rome is a body with a poisoned heart," Galen wrote in his secret codex, The Liber Salis. "The roads are the veins, and the legions are the rot. We must bring the winter to the blood."
The Battle of the Via Appia
The conflict peaked during the Great Fire of Rome. While the city burned—a fire likely started by the "Rejection" to purge the integrated districts—Galen and his "Salt-Hunters" attempted to intercept a shipment of "Sacred Sap" being moved along the Via Appia. This sap was the concentrated essence of the Progenitor Root, intended to be injected into the city's main aqueducts, which would have integrated every citizen of Rome in a single day.
The hunters utilized the Vitriol-Vesta, a primitive but effective chemical grenade. These were clay jars filled with a mixture of quicklime, sulfur, and concentrated sea-salt. When shattered against the iron armor of the Centurion-Integrated, the chemicals reacted with the moisture in the air and the sap in their veins, creating a "Thermal Rejection" that burned the vine from the inside out.
The Death of the Roman Root
In the tunnels beneath the Colosseum, Galen faced the Praetorian-Prime, the ultimate evolution of the Aorta host. This creature was no longer human; its skin was a translucent, veined membrane, and its heart had been replaced by a pulsing, violet organ the size of a shield. It moved with the speed of a heartbeat, its fingers elongated into "Sucking-Thorns" that could drain a man in seconds.
Galen did not use a sword. He used a Siphon.
He had developed a specialized bronze needle attached to a pressurized reservoir of Hyper-Saturated Brine. In a desperate gamble, he allowed the Praetorian to strike him, but as the creature's thorns entered his arm, Galen triggered the siphon. He didn't just fight the monster; he poisoned the entire network.
Because the Aorta Strain relied on the high-speed circulation of the Roman roads and aqueducts, the salt-poison Galen introduced moved with terrifying speed. It was a "Hemic-Collapse." The salt-ions bonded with the chlorophyll-mimics in the sap, creating a crystalline "logjam" in the creature's heart.
The Praetorian-Prime didn't just die; it exploded in a cloud of white dust.
The Great Stagnation
The systemic shock of the "Catacomb Rejection" caused the Vilevine's Roman network to shatter. Across the empire, "integrated" officials and soldiers suddenly collapsed as their blood turned to grit. This "Great Stagnation" was recorded by history as a series of plagues and the "Crisis of the Third Century."
Rome did not fall to the barbarians first; it fell to the Sudden Calcification of its internal infrastructure. The Vilevine, realizing that the "Aorta" approach was too prone to systemic failure, retreated into the dark, cold corners of the north.
Galen of Pergamum, like the sentinels before him, succumbed to the very cure he had created. His body was found in the catacombs, a perfect statue of white salt, his hand still gripping the bronze siphon. He became the fourth Silent Sentinel, guarding the secret history of the war beneath the streets of the Eternal City.
The Vilevine, however, was not finished. It had learned that to defeat the salt, it had to Encapsulate. It began to look toward the dark ages, where it would evolve into the Fungal-Strain, merging with the very earth and the dead to create the "Vampires" that would eventually haunt the Noir family's era.
