It was an ordinary night. So ordinary that Dan caught himself thinking it felt too calm. Like the quiet before a storm.
He was coming back from a run. The habit had stayed with him after the service. The air was cold and smelled of pine and wet soil. It had rained not long ago. Needles crunched softly under his boots.
Ahead, the faint light of his small cabin glowed between the trees. A few days of leave. Silence. No people. No signal. Exactly the way he liked it.
The door was slightly open.
He stopped.
Wind would not do that. Neither would an animal.
The forest stood silent around him, and his heart skipped a couple of beats.
He stepped inside.
At first glance everything was in place. But the air had changed. It felt thick, almost like water. Breathing felt strange, as if he were pushing through an invisible wall.
A low vibration hummed somewhere in his chest. Deep and dragging, almost physical.
He turned around and realized the door was gone.
Something appeared before him.
It had no shape and no light, yet it filled the room with a heavy presence. Like a gaze you cannot hide from. It did not threaten him, but it did not let him go either.
Dan expected fear.
It did not come.
Instead there was a strange feeling, as if someone had turned a page and now he stood on the other side of his own life.
He exhaled.
"So... not the park ranger."
And the world went dark.
When he woke in the white space, he could not tell how much time had passed.
There were no shadows here. No source of light.
Everything looked like emptiness and thick fog at the same time.
His thoughts moved slowly, as if through heavy liquid.
A figure appeared in front of him. Vague and trembling, like a reflection on water. Not human, yet not completely abstract either.
It did not speak, but he somehow understood that it was talking to him.
"You are human. You are ready. You are chosen. Not because you are special, but because you are suitable."
"Nice to hear," he muttered. "Almost sounds like a job interview. Who are you?"
"The name will mean nothing to you. We call ourselves Oaeuya."
"Alright. And why am I here?"
"Your life has ended. Now you are a tool. We will send you back. Very far back. You must prepare them. Unite them. Accelerate their development. This is your mission."
He blinked.
"Sorry, back... how far back? A few years? A century? Or are you serious about the 'very far' part?"
There was no answer.
The air seemed to grow denser and colder.
"I see," he exhaled. "So not a vacation. Not even a work trip."
He tried to smile, but it never quite formed.
"And what do I get in return? A new body? Superpowers? Or at least a guarantee that I will not go insane trying to talk to ancient people around a fire?"
No answer.
The air grew heavier again. A chill ran across his skin.
"I understand," he said quietly. "So nothing."
He exhaled again, this time without even trying to smile.
"And what if I fail?"
"Then the end will come. Not immediately, but inevitably."
The space trembled.
Images exploded inside his mind. Worlds swallowed by darkness. Planets falling silent under a cold wave of alien intelligence.
The Ganathi.
"They are coming. Slowly, but without stopping. In several thousand years they will reach Earth. In your calendar it will be the forty second century. If you do not change history, humanity will disappear."
He frowned.
"A few thousand years? That is not much. We could prepare. Build defenses, weapons, fleets, whatever."
"Even if all of humanity in your time focused on that goal, it would not be enough. The level required cannot be reached in two thousand years. What you see as a distant future is a single breath for the Ganathi. The work must begin not tomorrow, but at the very beginning. Hundreds of thousands of years earlier."
He stayed silent.
"So you will send me to the distant past."
"Three hundred thousand years into the past. That is where the path begins."
"Three hundred..." He stopped. "There are not even humans yet."
"This is the beginning. If it does not start there, no one will exist to face the enemy. And they are already almost human."
"And you cannot interfere yourselves?"
"We cannot. We are not even physically present here. We only guide. Like wind helping a tree grow."
"And how exactly am I supposed to do this?"
"Unite them. Do not allow them to divide. Turn humans into a people. Turn a people into a civilization that remembers its purpose. Turn that civilization into a defense. You will become their beginning. If you succeed, they will survive. Only a united humanity can survive."
Dan was silent.
Everything he had just heard sounded like a sentence. One direction. No return. No second attempt.
He tried to imagine it properly.
He was a man of the twenty first century. A city man who depended on coffee and hot water. A man who spoke languages that had not even been invented yet.
And now he would stand among beings who had only just learned to hold a stone.
"You understand they will kill me?" he said aloud. "On the first day. I smell wrong. I look wrong. I speak wrong. To them I am a strange and dangerous animal on two legs. The best outcome is they eat me so my spirit does not come back."
"If you fail, humanity will perish. The Ganathi leave no traces."
Dan fell silent again.
"And if I cannot do it? If they kill me on the first day. Or the second. Or after a year when I finally learn how to make fire but do something wrong?"
"Then humanity will perish."
Dan remembered the stories he once read about people falling into other worlds. In those stories the heroes built empires and gathered harems along the way.
He almost laughed.
This was nothing like that.
No glory. No way back. Only the duty to begin everything from nothing.
"And I will never return," he said. "No way at all?"
"No."
He nodded slowly.
"Everything you need is already with you. Your knowledge will remain. Your memory will remain partially. When the time comes, you will remember what matters."
"I will lose memory? Seriously?"
"It is safer. You will remember when you can survive on your own."
"And how do I survive without memory?" he asked. "I will not even know who I am. Or why I am there."
"You will only forget the mission. All other memories will remain."
Dan clenched his teeth.
Cruel. But honest.
No guarantees. No safety net.
He would be thrown into a world where every day was a fight for life. Where the weak simply died and no one cared. Where even food had to be taken with risk, and water itself could kill you.
He remembered everything he had read about ancient humans.
They were not stupid.
They were different.
Their minds worked differently, but not worse. They knew their world in ways he never knew his own. They could sense animals from a distance, read tracks like open books, and tell which roots would feed you and which would kill you within an hour.
They had survived that world for thousands of years.
And he...
He could not even start a fire without matches.
"I will have to prove I am worthy," he said quietly. "First to myself. Then to them. Only then will they listen."
"You are beginning to understand."
"And if I succeed? If I survive, if they accept me, if I teach them something... what happens next?"
"You will become the first link in a chain that must never break."
Dan closed his eyes.
A chain three hundred thousand years long.
And he was the first link.
If it broke, everything would collapse.
"Is that all?"
"This is only the beginning."
The world began to shrink, like a sheet pulled into a point of light.
He had time for one last thought.
I hope they at least give me a jacket.
Or something warm.
Then he vanished, and with him vanished his life.
Everyone he had known. Everything he had loved. Every road he might have walked.
All of it remained behind in a world that no longer existed for him.
A world where, hundreds of thousands of years later, humanity would face the darkness and most likely die.
Here, in this new reality, everything began again.
Not correction. Not adjustment.
A complete rewrite.
Every step he took. Every word he spoke. Every child he taught. Every custom he changed.
All of it would become the new foundation.
Nothing he knew as history would happen here.
There would be no Egypt. No Rome. No knights and kings. No internet. No nuclear bombs.
There would be something else.
Something he built.
Or something that collapsed because of his mistake.
He was not just a man thrown into the past.
He was a creator.
Or a destroyer.
There was no third option.
Three hundred thousand years.
A civilization that had to grow from nothing until it could stand against the Ganathi.
Or never exist at all.
Everything depended on him.
And he did not even remember how to start a fire.
Somewhere deep in ancient time, in a cold savanna where no human foot had yet walked, his new body lay on the ground.
It breathed.
It was ready.
The longest deployment in the history of humanity was about to begin.
