The beings known today as the Seakh did not originate within the human world. Their true birthplace lies beyond the boundaries of physical existence, in the same spiritual dimension inhabited by the entities humanity has long referred to as Jinn. Although many have attempted to classify the Seakh as another branch of those spirits, such a description is incomplete. They share the same origin, but they do not share the same destiny.
Long before the world learned to fear them, the Seakh were a forgotten people among their own kind.
Within the spiritual realm, they possessed no homeland, no authority, and no place they could truly call their own. Whether through exile, rejection, or the natural order of that dimension, the Seakh gradually became a population without purpose. While other spiritual races remained within their assigned domains, the Seakh began searching for something impossible.
A world beyond their own.
Unlike ordinary spirits, they believed existence should not be confined to a single dimension. They became obsessed with crossing the boundary separating the spiritual world from the realm of living matter. For centuries they searched for weaknesses between realities, attempting to force open passages into the human world. Countless attempts failed. Others ended before they could even begin. Yet the Seakh never abandoned their pursuit.
Eventually, humanity discovered traces of those attempts.
Not through religion.
Not through myth.
But through science.
Several world powers secretly became aware that an unknown spiritual species was repeatedly attempting to establish dimensional gateways across various locations on Earth. Rather than preventing these intrusions, they recognized an opportunity unlike anything civilization had ever encountered.
The answer came in the form of Isla Isabela.
An isolated island, removed from the attention of the outside world, where every experiment could remain hidden from history itself.
Governments granted the Seakh permission to open dimensional gateways there under strict observation. Officially, no such agreement ever existed. Unofficially, Isla Isabela became the largest laboratory humanity had ever constructed.
At first, the researchers knew almost nothing about the creatures emerging from the portals.
The earliest records described them simply as wandering spirits.
That changed after an event few people remember.
In the island's earliest years, before centuries of degeneration stripped away much of their intelligence, two Seakh were overheard communicating with one another. Their language was unlike anything human linguists had documented, yet one word appeared repeatedly throughout the conversation.
Seakh.
It was not a title.
Nor was it a scientific classification.
It was the name they used for themselves.
From that moment onward, every research document, biological record, military report, and classified archive abandoned their previous terminology. The designation remained unchanged for generations.
They were no longer referred to merely as spiritual entities.
They became known as Seakh.
As the years passed, another discovery transformed every assumption researchers had previously held.
The Seakh did not simply enter the world as wandering ghosts.
Whenever a human being died, a brief period existed before the soul completely departed from its physical vessel. During approximately the first twelve hours following death, the body remained vulnerable.
The Seakh exploited this moment.
Rather than creating bodies of their own, they entered the empty human vessel after its original soul had departed. Once the process was complete, the body resumed movement almost perfectly. Muscles responded. Eyes opened. Speech returned.
To an outside observer, nothing appeared unusual.
Friends recognized familiar faces.
Families believed their loved ones had survived.
Even experienced investigators struggled to distinguish the dead from the living.
The only truth hidden beneath the skin was that the person who had once occupied that body no longer existed.
Something else now looked through those eyes.
And unlike ordinary possession, a Seakh was capable of remaining within its host indefinitely.
As long as the body continued to function, the Seakh could continue living inside it.
Death, for them, had become little more than a doorway.
