The basic truth of the setting is that humanity never evolved completely alone.
Long before humans reached civilisation, the galaxy already had ancient predator species that modern mythology would eventually remember as vampires and werewolves. They weren't magical in the original sense. They were highly evolved biological species that spread across multiple worlds over extremely long periods of time.
The vampire-type species evolved toward immortality, intelligence, hierarchy, emotional suppression, and long-term control. They became incredibly stable biologically, but eventually that stability became stagnation. Reproduction declined, adaptation slowed, and their societies started becoming rigid and decaying.
The werewolf-type species evolved in the opposite direction. They prioritised adaptation, transformation, aggression, pack coordination, and survival pressure. They reproduced more successfully and adapted rapidly, but eventually became unstable. Mutation spirals, territorial wars, and biological over-adaptation pushed many of their worlds toward collapse.
Over time both species entered long periods of conflict and decline. Entire systems were devastated. Eventually the wider galaxy came to see both species as dangerous remnants of an older era. Whether they truly went extinct naturally or were deliberately eradicated depends on who tells the story, but by the time modern galactic civilisation stabilised, vampires and werewolves were considered extinct species.
Earth was never important politically. It was a distant, insignificant colony world that ended up becoming a refuge during the collapse periods. Small remnants of both species fled there long ago. Not empires or armies — just surviving bloodlines, broken houses, scattered packs, hybrids, and refugees trying to disappear.
What changed everything was humanity itself.
Humans turned out to be unusually compatible with both species biologically and psychologically. Over thousands of years, hidden integration happened constantly:
feeding,
reproduction,
intermarriage,
diluted hybridisation,
coexistence,
concealed bloodlines.
Eventually small amounts of vampire and werewolf genetic material spread quietly through the human population.
Not enough to transform everyone. Not enough to make humanity non-human.
But enough that humans slowly became convergence-compatible on a species-wide level.
Earth's environment suppressed most active expression for thousands of years. The atmosphere, magnetic field, and isolation of the planet kept those dormant traits mostly inactive. So humanity remained functionally human while carrying diluted remnants of extinct species genetics.
Meanwhile the surviving elders who stayed on Earth adapted differently. Some tried maintaining blood purity and old traditions. Others realised survival meant integrating into humanity completely. Those elders became hidden dynasties, wealthy families, isolated clans, corporations, political figures, criminal organisations, or simply disappeared quietly into civilisation.
Over time the original species identities blurred. Modern vampires and werewolves are no longer identical to the ancient galactic versions. They're Earth-adapted descendants shaped by thousands of years of coexistence with humans.
The wider galaxy never realised any of this survived.
As far as galactic civilisation knows, the predator species died out ages ago.
The reason Earth remained hidden is because of the MC.
The MC is one of the oldest surviving convergence beings still in existence. A stabilised hybrid from near the extinction era who remembers what happened before Earth disappeared from galactic awareness. Unlike modern strains, the MC retains much closer proximity to the original convergence state between vampire, werewolf, and human-compatible biology.
The MC knows Earth is effectively the last surviving refuge world of species the galaxy believes extinct.
If Earth were discovered, the consequences could be catastrophic:
some factions would want extermination,
others would want genetic harvesting,
others would attempt containment,
and some would see humanity itself as a dangerous resurgence of extinct predator evolution.
So for centuries the MC secretly maintained Earth's concealment.
Not through giant magical barriers, but through manipulation, erased records, destroyed expeditions, hidden navigation data, misinformation, and direct intervention when necessary.
Over time the MC became known throughout parts of the galaxy as a mysterious war figure — the "WarGod." Not because they ruled empires, but because they repeatedly appeared around forbidden archives, blacksite conflicts, extinction-era discoveries, and catastrophic military incidents. Nobody knows what species the MC actually is. Most think they're some kind of ancient war organism or relic from older civilisations.
The MC intentionally allows the myth to exist because it keeps attention away from Earth.
Then humanity enters space around the year 2100.
This becomes the major turning point of the setting.
Humans begin leaving Earth, building colonies, mining asteroids, and travelling through environments humanity was never exposed to before. Deep-space radiation and exotic cosmic exposure start interacting with the dormant genetic signatures hidden within humanity.
That causes dormant traits to activate.
Some humans begin developing vampire-like characteristics:
regenerative adaptation,
sensory enhancement,
slowed ageing,
blood dependency,
emotional intensification.
Others begin developing werewolf-like traits:
transformation episodes,
territorial instincts,
accelerated healing,
sensory expansion,
aggressive adaptation responses.
Some develop unstable hybrid traits.
The important part is that this isn't a zombie apocalypse where civilisation collapses overnight. Humanity slowly fragments into emerging evolutionary branches while still trying to function as modern civilisation.
Governments, corporations, bloodlines, packs, and hidden supernatural factions all react differently.
Some want control. Some want integration. Some want cures. Some believe humanity is evolving. Some fear the return of the extinct species.
The MC understands the deeper truth: humanity is no longer simply carrying extinct remnants.
Humanity is becoming something new.
The original vampire and werewolf civilisations are effectively gone already. What survives on Earth are descendants, diluted strains, hybrids, and adaptations shaped by humanity over thousands of years.
In a strange way, the extinct species already lost.
They survived by dissolving into humanity.
Now the galaxy unknowingly faces the possibility that humanity itself may become the next evolutionary stage of those ancient species — but potentially more adaptable, more numerous, and more dangerous than the originals ever were.
