Sanguis Aeternum
"Thick as guilt. Old as sin. Precious as life."
Introduction
Vampire blood.
A tale as old as time.
Between myths and buried beneath countless stories whispered and shattered, lies the truth.
And it is vile.
The Cataclysm laid bare that truth, as it did so many others.
The Immortals call it Sanguis Aeternum, a force beyond real measure. Their blood is liquid sacrilege, the living pulse of the Primordials’ defiance of reality. It is the root of their power; both anchor and wings.
It sings softly with temptation.
It lures you close and when you reach out, it consumes.
Vampire blood is life trapped within death.
It is a paradox.
And it hungers.

Origins
No one remembers the first drop.
Some say it was the price of arrogance; the moment death was defied and hunger was born. Others praise it as the ultimate gift: the dark essence of power made real.
But beneath myth and reverence lies something older.
The blood of the Immortals is unlike any other - not just life, not just magic, but something in between.
It began with the Four.
The Primordials - first of the vampires, first of the mages - birthed it in a time beyond memory. Through a profane ritual and an unholy pact, they defied death itself, trapping it in the cage of flesh and will.
Their blood was both the price and the reward.
And ever since, it pulses in the dark like a secret no god dares claim.
Properties
From a source of vitality for the Immortals, to a panacea for mortals and a conduit of magic for the covens, vampire blood - Sanguis Aeternum - is a material unlike any other.
It is alive, it remembers, and it corrupts.
Its properties shift depending on its state. Within the body of the undead, it hums with forbidden life. Once spilled or harvested, it begins to unravel: changing form and purpose.
There are those who claim it has its own "moods". Others whisper that it listens.
All agree on one thing:
It should not exist.
The Living Essence
"It is our legacy. Our leash. The last alive god."
"Blood is power. And power demands worship."
"It's sorcery without price. That alone should be warning enough."
Blood.
It is not a thirst.
It is not a craving.
It is an obsession so total, it swallows all else.
An Immortal's blood is their essence; the pulse of eternity caged in rotting flesh. It does not merely sustain them. It defines them. It is their their chains and their strength.
With it, they can mend bones like clay, shrug off wounds that would kill an army, rip steel apart like it was paper. Their myths are not exaggerated; if anything, they are understated. Every story of their speed, endurance, and fury begins with a crimson drop igniting in their veins like holy oil.
But even that is not the whole truth.
Before the Cataclysm, their blood was more than fuel. It was the source of Sanguinis - vampiric sorcery, born not from the Pillars of Magic, but from defiance.
Where mages courted risk with every spell, vampires simply bled.
Their spells were written in veins. Their runes were nerves. Their rituals, acts of consumption.
Each of the four bloodlines, shaped by one of the ancient Primordials, birthed their own branch of this power. Some commanded mind and emotion. Others twisted memories or flesh. All of it stemmed from one truth:
The blood was the spell and so long as it flowed, Sanguinis obeyed.
But then came the Cataclysm.
Magic shattered. The world howled. And the blood grew silent and hungrier than ever.
Sanguinis is no longer possible. The connection is severed, and no one knows why. The Immortals rarely speak of it, but when they do, the hunger in their eyes grows darker. The absence aches louder than any wound. It is not just the loss of power, it is the loss of self.

The Decaying Blood
Outside a vampire’s body, their blood is a fleeting treasure; a source of power that must be consumed or preserved within a couple of days. Without magical wards or technical refrigeration, the blood begins a slow, inevitable death.
First, it settles into a thick, crimson deposit, coagulating like dark resin. Over time, the liquid part becomes translucent, revealing clusters of jagged crimson crystals resting like shattered rubies at the container’s bottom. These Bloodshards are prized for their haunting beauty, often fashioned into ornaments or trophies to intimidate foes.
Yet, these crystals are far more than decorative. Those who know their secrets can forge them into weapons and ammunition that wound vampires in ways no mortal blade can.
0–12 hours
Fresh blood remains a deep, vibrant crimson, thick and pulsing with latent power.
12–24 hours
The blood thickens, becoming syrupy and sluggish. Dark deposits start to settle at the bottom of its vessel, like the first shadows of death creeping in.
24–48 hours
The liquid fades, turning nearly transparent as the crimson settles fully, revealing sharp, crystalline deposits clustered beneath. These jagged Bloodshards gleam like rubies.
After 48 hours
The blood is considered “dead.” It loses all vitality and power. What remains are the Bloodshards; dried sin given form, sharp and unforgiving.
Bloodshard Arms
Bloodshard weapons are whispered of in fear and awe. Forged in secret by a rare few, these jagged blades and shards of crystalline ammunition carry the fragments of the vampiric curse, but in reverse. A dagger tipped with Bloodshard can pierce the skin of an Immortal and leave wounds that refuse to close, burning with a cold fire that no amount of blood can heal. Unlike typical wounds, these injuries resist the supernatural healing powers of the Immortals’ own vitae; only the slow passage of time can mend what Bloodshard blades rend.
Such weapons are rare and deadly and to wield one is to brand yourself a marked enemy of the Undying; their possession guarantees relentless pursuit by the most merciless vampire enforcers.
In the end, Bloodshards are the crystallized sins of eternity, weapons born from the very essence of Immortal curse and defiance: sharp, unforgiving, and eternally damned.
Ancient Blood
The decay timeline is not absolute. Blood of elder vampires, those who have walked the world for centuries or longer, seems to resist this process. Ancient blood is said to retain a faint echo of life and power long after fresh blood would have perished. Such blood takes weeks, months, or even years to crystallize, if it does at all.
Some believe that this venerable blood is aware; that it recognizes those who touch it. Others whisper that this old blood carries memories, that it murmurs if kept too long.
To hold Ancient Blood is to cradle a fragment of eternity, a blessing and a curse; a relic of unholy power, both living and dead.
Crimson Echoes
It drips through history like a forgotten god’s tear: crimson, cursed, alive.
Vampire blood is memory, hunger, and power braided into a dreaded singularity.
Whispers. Cravings. Shards.
Its forms are endless.
We call it a curse.
We treat it as myth.
In this broken world, it is closer than ever. So, think, just for a minute...
