On Vampirism

The Nature of Sanguivivens and Parasitus Sanguinis

By Theremos Vallis, Scholar of the Silverflame Guild


Vampires and the Layman's Lexicon

The terms “vampire” and “vampirism” occupy a prominent place in folklore, conjuring images of shadowy figures, blood-soaked fangs, and the grim specter of undeath. While evocative, these terms fail to convey the true complexity of the phenomenon they describe. To move beyond superstition and into understanding, the Silverflame Guild has adopted more precise terminology.

In scholarly discourse, these beings are referred to as Sanguivivens—"Blood-living"—a name that reflects their unique existence: a state neither fully alive nor entirely dead, sustained through the consumption of blood. The transformative force at the heart of their nature is Parasitus Sanguinis, or the "Parasitic Curse," an aetheric phenomenon that invades, alters, and ultimately consumes the host.

This work seeks to move beyond myths and fear to illuminate the mysteries of the Sanguivivens, grounding its observations in rigorous study, anecdotal testimony, and aetheric principles. May it inspire clarity, caution, and a relentless pursuit of knowledge in those who seek to unravel these shadowed mysteries.

At the core of the Sanguivivens lies the enigmatic force known as Parasitus Sanguinis. More than a mere biological parasite, this entity exists at the intersection of the physical and aetheric, transforming its host into a vessel of perpetual hunger and unnatural vitality.

The Nature of the Parasite

Parasitus Sanguinis invades the body, commandeering its vital systems to sustain itself. While its exact method of transmission remains unclear, evidence points to blood exchange, particularly during near-fatal exsanguination, as the likely vector. The parasite anchors itself within the host’s heart, becoming the locus of its influence.

From this nexus, the parasite orchestrates a gradual transformation. Human cells are replaced with "cursed cells," engineered by the parasite to sustain the host’s new state. This metamorphosis eventually affects every organ and tissue. Although the host retains memories and cognitive faculties, they are irrevocably altered—humanity eroded as the parasite asserts control. Sanguivivens exist in a liminal state, bridging life and death. Sustained solely by blood, they are predators whose existence defies natural laws.

Cultural and Magical Considerations

The Sanguivivens are regarded with fear and fascination. Most cultures view them as cursed abominations, while a few rare traditions revere them as beings that transcend mortality.

Magically, Parasitus Sanguinis interacts unpredictably with aetheric forces. It disrupts certain spells while amplifying others, suggesting a complex relationship with magical energies. One particularly taboo act is mutual feeding between Sanguivivens, during which their parasites merge temporarily, creating a gestalt entity that shares thoughts and memories. This act is rare and deeply feared, as it strips away all boundaries of privacy.

Feeding Habits

The ideal sustenance for a Sanguivivens is fresh, living human blood, providing immediate energy with minimal effort. Blood from non-human sources is less efficient, requiring significant aetheric processing, while dead blood is largely unusable and even harmful.

Sanguivivens exhibit an instinctive ability to "taste" the vitality of their prey, an ability likely tied to the parasite’s aetheric resonance. This enables them to evaluate potential sustenance with uncanny precision.

When deprived of blood, the parasite retreats to the heart, entering a state of torpor. In this hibernation, the Sanguivivens can endure for extended periods, drawing faint aether from the environment to sustain minimal functions. Prolonged starvation leads to physical decay as the parasite sacrifices non-essential tissues to preserve itself. Complete depletion results in true death, though this is a prolonged process.

Parasitus Sanguinis is both a curse and a gift. It enslaves its host to an eternal hunger while granting extraordinary resilience and regenerative powers. Over time, the host’s humanity erodes as the parasite replaces their cells, transforming them into something neither wholly parasite nor person.

Fully transformed Sanguivivens may transcend even the parasite’s survival instincts, evolving in ways unique to their experiences. The ultimate fate of such beings remains speculative, a question for philosophers and theologians.

On the Apparatus of Feeding

Among the myriad adaptations observed in the Sanguivivens, none are as distinctive or functionally vital as their so-called “fangs.” These structures are not mere extensions of natural teeth but rather complex mechanisms, engineered by Parasitus Sanguinis to address the dual challenges of feeding: access and extraction.

Contrary to popular belief, the fangs of the Sanguivivens are not merely elongated teeth. They are, in fact, hollow keratinous sheaths that develop around the lateral incisors, showcasing the parasite’s biological ingenuity. These sheaths are thin yet remarkably strong, designed to pierce skin and vessels with minimal effort while maintaining structural integrity during feeding.

What makes these fangs truly remarkable is their retractable nature. When not in use, the sheath closely conforms to the shape of the underlying tooth, appearing as a normal incisor. However, when extended, the sheath elongates and curls inward along its rear seam—a natural weakness in its structure. As the sheath extends beyond the tooth, this curling action sharpens its tip into a precise, needle-like point with a narrow central channel.

During feeding, the vampire’s tongue presses against the seam, reinforcing the sheath’s structure and stabilizing the tube. Once the fangs puncture a vessel, the natural pressure disparity caused by the victim's heartbeat facilitates a steady flow of blood into the vampire’s mouth with little additional effort. The process is highly efficient, ensuring minimal wastage and rapid sustenance. As blood begins to flow, the parasitic curse capitalizes on the victim's circulatory pressure, reducing the vampire's need to actively draw blood through suction.

This design reflects the evolutionary ingenuity of Parasitus Sanguinis, merging efficiency and concealment. When the fangs retract, the seamless housing of the sheath preserves the illusion of normality, allowing the Sanguivivens to blend into mortal society until the moment they strike.

The feeding process is further refined by modifications to the Sanguivivens’ saliva. This saliva has numbing properties that reduce pain and antibacterial agents that ensure clean feeding. These adaptations serve a dual purpose: they facilitate the act of feeding and prevent complications that could hinder the host’s survival. While samples of vampire saliva have shown no capacity to transmit the parasitic curse, ongoing study may yield further insights into its properties.

Other Feeding Mechanisms

The vampires studied by the Silverflame Guild, such as those of the Morvain line, display feeding adaptations centered on their retractable fangs. However, guild records and field accounts suggest significant variations in vampiric feeding mechanisms within the observed cases, indicating potential divergences even among known vampires. These accounts describe alternate structures, such as canines modified for puncturing, tongue-like appendages capable of siphoning blood, and even leech-like mouths designed for suction.

For example, some guild texts recount vampires whose canines were adapted as primary feeding tools, sharper and more prominent than the lateral incisors observed in the Morvain line. These adaptations might represent early stages of the parasitic curse’s experimentation or localized variations tailored to specific environments.

Another peculiar adaptation noted in field reports involves a tongue-like appendage, described as flexible and hollow, capable of drawing blood directly from wounds. This mechanism, while less efficient than the retractable fangs of the Morvain vampires, could suggest an intermediate evolutionary stage in the curse’s trial-and-error progression.

Lastly, more obscure legends speak of creatures with leech-like mouths, capable of latching onto prey and drawing blood through suction alone. While such descriptions border on the fantastical, they may reflect exaggerated accounts of less refined adaptations within certain cursed lines.

These recorded variations are not presented as evidence of an ongoing vampiric evolution but rather as remnants of earlier, divergent experiments by Parasitus Sanguinis. The consistency and refinement observed in the Morvain vampires suggest that the parasite has since settled on more effective adaptations. However, these documented differences serve as a reminder that vampirism is not a static phenomenon and that no single line can be assumed to represent the entirety of this curse’s capabilities.

If multiple primitive vampires existed, each hosting a variant of Parasitus Sanguinis, it is plausible that distinct vampiric lines emerged. Geographical isolation and divergent survival needs could explain the variation in traits. These variations, real or exaggerated by folklore, highlight the adaptability and enigmatic nature of the parasitic curse.

Vulnerabilities

Sanguivivens possess significant weaknesses:

  • Sunlight: Agitates the cursed blood, causing it to ignite.
  • Silver: Disrupts the aetheric harmony, impeding healing and causing lasting damage.
  • Fire: As destructive to their bodies as it is to mortals.
  • Beheading: Impairs function but does not guarantee death unless the brain or heart is destroyed.

Older vampires exhibit reduced vulnerability, likely due to the dominance of cursed cells in their physiology.

Conclusion

The Sanguivivens represent both the fragility and corruption of humanity, a duality that challenges our understanding of life and death. While Parasitus Sanguinis offers power and resilience, it exacts a devastating cost—eroding humanity in favor of predatory efficiency.

As we study these creatures, we must balance fear with knowledge, for only through understanding can we hope to protect humanity while preserving the ideals of the Silverflame Guild. May this work guide future scholars in illuminating the shadows and confronting the mysteries within.
