INTRODUCTION
Logline: At the height of their power, the Engineers create the perfect organism—and it tears them apart. One lover becomes a god of war. The other becomes human.
Timeframe: Millions of years ago
Protagonists: Ishara (genetic architect) and Vel'kor (military strategist)
Worlds: Engineer Homeworld · Yautja Prime · Aru'ndi · Earth
SYNOPSIS
Ishara, a young Engineer geneticist, discovers a primitive parasitoid on a dead world and begins sculpting it into something beautiful. Over centuries, she creates the Xenomorph—a perfect organism. But her mate Vel'kor sees only a weapon.
As the Engineer Conclave debates, Vel'kor secretly sabotages Ishara's laboratory, causing a containment breach. The Xenomorphs are released into the wild on Aru'ndi. The Engineer species fractures: the Purists (led by Vel'kor) want to weaponize everything; the Remorseful (led by Ishara) want to lay down their tools and seek forgiveness.
Vel'kor attacks Yautja Prime, a peaceful world, to harvest genetic material. The Yautja refugee fleet escapes. Ishara leads the Remorseful across the galaxy to Earth, where she releases her genetic signature into the primordial ocean—seeding humanity.
The Yautja refugees, now led by Kai'sa and Ka'thar, receive Ishara's signal and journey to Aru'ndi, where the Xenomorphs await. The stage is set for the Origin Saga.
FADE IN:
EXT. DEAD WORLD - MILLIONS OF YEARS AGO
A planet of ash and silence. No atmosphere. No life. No future.
A single ENGINEER ship descends through the darkness. Its hull is organic—curved, bioluminescent, beautiful. It has traveled across galaxies to reach this grave.
INT. ENGINEER SHIP - CONTINUOUS
ISHARA stands at the observation deck. She is young by Engineer standards—three thousand years old. Her face is pale, hairless, elegant. Her eyes are not cold. They are curious.
She watches the dead world approach.
ISHARA
(to herself)
Nothing lives here. Nothing ever lived here. Nothing ever will.
She turns from the window. Her laboratory awaits.
INT. ENGINEER SHIP - LABORATORY - CONTINUOUS
Ishara works. Her hands move with precision born of millennia. She is a genetic architect—one of the finest her species has produced.
Before her: a specimen container. Within it: a simple organism. Parasitoid. Unremarkable. An evolutionary dead end on a dying world.
ISHARA
(recording)
Specimen Zero. Primitive neural network. Basic host implantation. Limited morphological plasticity. But there is potential.
She begins to sculpt.
TITLE CARD: YAUTJA PRIME - THE GOLDEN AGE
EXT. YAUTJA PRIME - FESTIVAL GROUNDS - DAY
Golden light. Spires of obsidian and living stone rise from mist-shrouded mountains. Waterfalls descend through floating gardens. The architecture is ancient, elegant, undisturbed.
The YAUTJA gather in vast plazas. They wear robes, not armor. Their mandibles frame gentle expressions. Children weave between adults, their dreadlocks decorated with ceremonial beads.
Music. Not electronic—organic, harmonic, produced by throat and mandible together.
KAI'SA stands among them. She is young. Her robes identify her as a memory weaver—an archivist, a historian, a keeper of what was and what is.
KA'THAR stands beside her. He wears the uniform of the Celestial Guard, but it is ceremonial. He has never fired his weapon in anger. None of them have.
KAI'SA
You're staring.
KA'THAR
I'm admiring.
She almost smiles.
KAI'SA
Admiring what?
KA'THAR
That you haven't tripped over your robes yet.
She does smile. She shoves him. He does not move.
KA'THAR
(softer)
You'll be fine tomorrow. The Council respects you.
KAI'SA
The Council respects my grandmother. They tolerate me.
KA'THAR
Then they are fools.
A pause. The music swells. A child runs past—KAI'SA'S DAUGHTER, six years old, dreadlocks barely grown, laughing.
EXT. YAUTJA PRIME - SPACE - CONTINUOUS
Beyond the atmosphere, beyond the defense platforms, beyond the peaceful void: nothing. Nothing yet.
INT. ENGINEER HOMEWORLD - CONCLAVE CHAMBER - DAY
The ENGINEER CONCLAVE convenes. They are ancient beings, seated in a vast amphitheater of obsidian and light. Their faces are serene. Their eyes are patient.
VEL'KOR stands before them. He is Ishara's mate. His face is harder than hers—not cruel, but certain. He wears the insignia of military command.
VEL'KOR
Ishara has been working on Aru'ndi for three centuries. Her project shows promise.
THE ELDER
Promise of what?
VEL'KOR
Perfection. The organism she has created—the Xenomorph—is capable of rapid adaptation, efficient reproduction, and complete host assimilation. It is, quite simply, the most effective biological weapon ever engineered.
THE ELDER
We do not require weapons.
VEL'KOR
We do not require them now. But the universe is vast. And not all of it is friendly. Ishara has given us a gift. We should use it.
THE ELDER
And what does Ishara say?
VEL'KOR
Ishara... is an artist. She does not see the military applications. She sees only the beauty of the creation.
THE ELDER
Then perhaps we should listen to the artist.
Vel'kor's expression shifts, hardens.
VEL'KOR
With respect, Elder. Artists do not always understand what they have made.
The Elder regards him. For a long moment, neither speaks.
THE ELDER
We will consider your proposal.
VEL'KOR
That is all I ask.
He bows. He departs. The Elder watches him go. His ancient face reveals nothing.
TITLE CARD: ARU'NDI - THE LABORATORY WORLD - THREE CENTURIES LATER
EXT. ARU'NDI - ISHARA'S LABORATORY - DAY
A world of jungle and mountain, ocean and cloud. At its heart: a vast complex of Engineer architecture—curved towers, bioluminescent pools, containment chambers sunk deep into the bedrock.
ISHARA works. She has not aged. Engineers do not age.
Before her: a XENOMORPH DRONE. Fully formed. Sleek. Terrible. Beautiful. It watches her with patient, alien eyes.
ISHARA
(recording)
Specimen One-Seven-Nine. Neural integration: complete. Host assimilation: optimal. Morphological stability: within acceptable parameters. You are perfect.
The creature does not respond. It does not need to. Ishara does not see VEL'KOR enter. He stands in the shadows of her laboratory, watching her with the patience of a hunter.
INT. ISHARA'S LABORATORY - PRIVATE QUARTERS - NIGHT
Ishara sleeps. Engineers rarely sleep. But she is tired—not of body, but of spirit. Vel'kor sits beside her. His face is softer now, in the darkness. He reaches out, almost touches her cheek.
VEL'KOR
(whisper)
You have given them a gift. They do not understand it.
Ishara stirs. Her eyes open.
ISHARA
Vel'kor.
VEL'KOR
I did not mean to wake you.
ISHARA
You did. The Conclave rejected your proposal.
VEL'KOR
They deferred it. There is a difference.
ISHARA
Is there? You want to weaponize my children.
VEL'KOR
I want to protect our people.
ISHARA
From what?
VEL'KOR
From whatever comes.
ISHARA
And if nothing comes?
VEL'KOR
Then we have wasted nothing. But if something comes... I did not create the Xenomorph to be a weapon. I created it because it was beautiful. And now you want to make it ugly.
VEL'KOR
I want to make it useful.
A long silence.
ISHARA
Perhaps that is the same thing.
EXT. YAUTJA PRIME - COMMAND SPIRE - DAY
Ka'thar trains. Not for war—there is no war. He practices forms, rituals, movements passed down for generations. His blade never touches an enemy. It never will.
Kai'sa watches from the observation deck. Her daughter sits beside her, carving another ship.
KAI'SA
You don't have to train every day.
KA'THAR
(without stopping)
Yes, I do.
KAI'SA
Why?
KA'THAR
Because if I stop, I might forget.
KAI'SA
Forget what?
He pauses. His blade lowers.
KA'THAR
I don't know. That's why I can't stop.
He resumes his forms. Kai'sa watches. Her daughter carves. The sun sets behind the spires. No one knows this is the last sunset.
INT. ARU'NDI - CONTAINMENT CHAMBER - DAY
Ishara walks among her children. Rows of containment vessels line the walls—each holding a Xenomorph in various stages of development. Drones. Warriors. A single QUEEN, gestating in isolation.
The creatures watch her. They do not attack. They do not threaten. They simply... observe. She is their mother. They know her scent, her voice, her presence. She is the only thing in the universe that has ever shown them kindness.
ISHARA
(to the Queen)
He wants to take you from me. He wants to put you in ships. Send you across the galaxy. Use you to conquer worlds that have never heard your name. He does not understand that you are not a weapon. You are a species. You are my children. You deserve a world of your own. Not a war.
The Queen's tail moves, slowly, deliberately. A response? Or simply reflex? Ishara does not know. She will never know.
INT. ENGINEER HOMEWORLD - VEL'KOR'S QUARTERS - NIGHT
Vel'kor stands before a star map. His finger traces a spiral arm. A golden system. An uncharted world.
VEL'KOR
(to his subordinate)
What do we know about this species?
SUBORDINATE
Very little, Architech. They call themselves Yautja. They are peaceful. Advanced. They have never developed weapons beyond ceremonial armaments. No wars. No conflicts in recorded history. They resolve disputes through ritual and mediation.
VEL'KOR
They are soft.
SUBORDINATE
They are civilized.
VEL'KOR
(turning)
Civilization is softness. Softness is vulnerability. Vulnerability is extinction.
He zooms in on Yautja Prime. The spires. The gardens. The children playing in the plazas.
VEL'KOR
We are doing them a favor. We are teaching them, before something worse arrives. Prepare the fleet.
INT. ARU'NDI - ISHARA'S LABORATORY - NIGHT
Alarms. Red light. Containment breach. Ishara runs through corridors filled with smoke and screaming. Not her voice—the voice of her children. The Xenomorphs do not scream. But she hears them anyway.
A containment vessel has cracked. Not broken—cracked. Deliberately. Sabotage. Black liquid seeps into the ventilation system.
ISHARA
(into comms)
Vel'kor. Vel'kor, respond.
Silence.
ISHARA
What have you done?
No response. There will never be a response. A XENOMORPH DRONE emerges from the smoke. It does not attack her. It simply stands, trembling, its carapace smoking, its inner mouth twitching in distress.
ISHARA
(to the creature)
I am sorry. I am so sorry.
The creature does not understand. It only knows pain. It screams. The hive awakens.
EXT. ARU'NDI - LABORATORY COMPLEX - CONTINUOUS
Ishara stands at the observation deck. Below her: her children, her life's work, her greatest sin—pouring from the containment chambers, flooding the jungle, claiming the world as their own. She does not try to stop them. She cannot. She opened the cage herself.
ISHARA
(recording)
Ishara, Architect of Life. Final entry. The Xenomorph program is terminated. The specimens have been released into the wild. They will evolve without our guidance. They will become something we cannot control. They will become what they were always meant to be. Not weapons. Not tools. Not soldiers. Children.
She watches the jungle swallow her laboratory.
ISHARA
I am leaving now. I will not return.
She walks toward her ship. Behind her: the hive grows.
INT. ISHARA'S SHIP - BRIDGE - CONTINUOUS
Ishara sits at the helm. Her hands do not tremble. She is beyond trembling. Her ship lifts from Aru'ndi. Below: a world transforming. The Xenomorphs are already adapting, spreading, claiming territory. They do not need her anymore. They never did.
ISHARA
(to herself)
Where do I go?
The star map activates. Thousands of worlds. Thousands of possibilities. Her hand hovers over the console. Then stops. A single world. Blue. Green. White. At the edge of the galaxy. Unseeded. Unspoiled. Unknown. She has never seen it before. She does not know why she chose it. But she does.
ISHARA
Set course.
The ship accelerates into darkness.
TITLE CARD: YAUTJA PRIME - THE DAY BEFORE
EXT. YAUTJA PRIME - FESTIVAL GROUNDS - NIGHT
Kai'sa cannot sleep. She walks through the empty plazas, past the silent spires, beneath the light of three moons. Her daughter's carving rests in her palm. The ship. The escape. The journey to somewhere else. She does not know why she carries it. She only knows she cannot put it down.
KA'THAR
(behind her)
You should rest.
KAI'SA
So should you.
He steps beside her. His ceremonial armor is gone. He wears simple robes, like any other citizen.
KA'THAR
Tomorrow is your ceremony. You should look well-rested. The Council expects it.
KAI'SA
The Council expects me to be boring.
Almost a smile.
KA'THAR
You will be. Exceptionally boring.
They stand in silence. The moons drift.
KAI'SA
Do you ever think about what's out there? Beyond the Veil. Beyond known space. Beyond everything we've ever seen.
KA'THAR
No.
KAI'SA
Liar.
A pause.
KA'THAR
Yes. I think about it.
KAI'SA
What do you think is there?
KA'THAR
Nothing. And everything. That is not an answer. It is the only answer I have.
She looks at him. His face is hidden in shadow, but his mandibles are relaxed. Peaceful. Almost content. She does not know that in twelve hours, his face will be burned beyond recognition. She does not know that in twelve hours, she will be a refugee. She does not know that in twelve hours, everything she loves will be ash. She only knows that the night is quiet, and he is beside her, and her daughter sleeps safely at home. It is enough.
EXT. YAUTJA PRIME - SPACE - DAWN
The defense platforms detect a distortion. Then another. Then a hundred. Ships emerge from folded space. Not Yautja design. Not anything in the Celestial Guard's archives. They are vast. Organic curves. Bioluminescent hulls. Silent. They do not transmit. They do not respond to hails. They simply... arrive.
COMMANDER VOK
(over comms)
All stations, all stations—unknown fleet in orbit. Do not fire. Repeat, do not fire. Identify—
The lead ship opens. Not a weapon bay. Not a missile tube. A containment vessel. Translucent. Filled with black liquid. Released.
EXT. YAUTJA PRIME - FESTIVAL GROUNDS - MOMENTS LATER
The sky changes color. Blue becomes amber becomes black. Kai'sa looks up. Her daughter is in her arms. Ka'thar is already moving, pushing through the crowd, his ceremonial weapon drawn.
KA'THAR
Shelter. Now.
KAI'SA
What is—
The first impact. Not explosive—chemical. Black rain falls on the spires, the gardens, the plazas. A Yautja touches his face. His mandibles soften. His eyes widen. He collapses. Then another. Then a hundred.
KAI'SA
(to her daughter)
Don't look. Don't look, don't—
Ka'thar grabs her arm. His face is not gentle now. It is something else. Something she has never seen.
KA'THAR
Move.
EXT. YAUTJA PRIME - COMMAND SPIRE - CONTINUOUS
Ka'thar drags Kai'sa through the corridors. Her daughter is pressed against her chest, face buried, small body trembling.
KA'THAR
(into comms)
Vok. Vok, respond.
COMMANDER VOK
(static, breaking)
...cannot... they are not... it's in the water, in the air, in—
Silence.
KA'THAR
Vok?
No response. A Yautja soldier runs past them. His eyes are blank. His mandibles drip black foam. He does not see them. He walks off the balcony.
KAI'SA
(whisper)
What are they?
KA'THAR
I don't know. But I will learn.
EXT. YAUTJA PRIME - SPACEPORT - DUSK
The spaceport is chaos. Thousands of Yautja press against boarding gates. Ships launch erratically, without clearance, without formation. Ka'thar forces a path through the crowd. Kai'sa follows, her daughter still against her chest.
KA'THAR
(to a docking officer)
I need a ship. Military classification. Time-dilation capable.
OFFICER
All military vessels are engaged—
KA'THAR
I don't need a warship. I need a refugee ship. For civilians. For them.
He gestures at Kai'sa. At her daughter. At the thousands behind them. The officer hesitates. Then:
OFFICER
Bay seven. The Remembrance. She's not armed.
KA'THAR
She doesn't need to be.
INT. REMEMBRANCE - BRIDGE - CONTINUOUS
Ka'thar at the helm. His fingers move across unfamiliar controls. He was trained for defense, not evacuation. Kai'sa straps her daughter into a survival couch. The child's face is pale, her mandibles slack with shock.
KAI'SA
Stay here. Do not move. Do you understand?
KAI'SA'S DAUGHTER
(small)
Mother—
KAI'SA
I will come back. I promise.
She kisses her daughter's forehead. She turns away. She does not see the child's eyes follow her.
EXT. YAUTJA PRIME - SPACE - NIGHT
The Remembrance lifts from the burning city. Below: spires collapsing, gardens burning, the golden light extinguished. Ka'thar watches the screen. His face is stone.
KAI'SA
How many?
KA'THAR
Us. Perhaps a thousand more.
KAI'SA
A thousand... out of billions.
KA'THAR
Yes.
A pause.
KAI'SA
Where do we go?
KA'THAR
Away. Away, and then forward. Until they cannot follow.
He looks at the controls. The time-dilation drive is armed. One button. One jump. One escape. His hand does not move.
KAI'SA
Then why haven't you—
KA'THAR
Because if we leave... then it is really over. As long as we remain in orbit, we are still her children. We are still Yautja. We still have a home. The moment we jump... we become refugees. Wanderers. A people without a world. I am not ready to become that.
KAI'SA
Neither am I. But we will starve here. And our children will starve after us. And the invaders will have won.
Ka'thar closes his eyes.
KA'THAR
Yes.
KAI'SA
Then we must become something else. Not refugees. Not wanderers. Not a people without a world. We are the seed. And seeds must leave the dying tree.
Ka'thar opens his eyes. He looks at her. Something shifts in his face—not acceptance, not peace. But recognition.
KA'THAR
When?
KAI'SA
Now.
INT. REMEMBRANCE - BRIDGE - MOMENTS LATER
Alarms. Not combat—detection.
VEYN
(senior surviving officer)
Unidentified signal. Bearing two-seven-mark-four. Weak, but consistent.
KA'THAR
Source?
VEYN
Unknown. The transmission protocol is not in our archives. Wait. There is more. The signal contains navigational data. A destination.
KAI'SA
A destination for whom?
VEYN
For us. The signal is addressed to the Yautja refugee fleet. By name.
KA'THAR
That is impossible. No one knows we are here. No one knows we survived.
VEYN
Someone does.
Kai'sa stares at the display. The destination rotates slowly. A planet. Green. Blue. White.
VEYN
Atmosphere: breathable. Gravity: within tolerable range. Temperature: variable but survivable. It appears to be... an invitation.
KAI'SA
From whom?
VEYN
The transmission is signed. "From the hand of Ishara, Architect of Life, Mother of Monsters, Keeper of Remorse."
Kai'sa does not breathe.
KAI'SA
(whisper)
Who is Ishara?
VEYN
I do not know.
Ka'thar stares at the glyphs. His mandibles tighten.
KA'THAR
She knows our name. She knows we survived. She knows we are here. She may know who destroyed our world.
KAI'SA
Then we go to her. And we ask her why.
KA'THAR
Yes. Set course.
EXT. SPACE - DEPARTING YAUTJA PRIME - CONTINUOUS
The seventeen vessels break orbit. Behind them: the tomb world, shrinking, fading, becoming memory. Ahead: unknown space. An uncharted system. A signal from a dead woman. Kai'sa stands at the observation port. Her daughter's carving rests in her palm—the crude ship, the joyful lines, the six-year-old's hope. She does not look back.
TITLE CARD: ISHARA - MILLIONS OF YEARS EARLIER
EXT. SPACE - ENGINEER SPACE - CONTINUOUS
Ishara's ship departs the Remorseful fleet. Behind her: her people, scattering to anonymous worlds, seeking oblivion. Ahead: unknown space. An uncharted system. A blue-green world calling her name. She does not look back.
EXT. SPACE - APPROACHING EARTH - CONTINUOUS
Her ship passes the orbit of a gas giant. Then a barren rock. Then another. The star grows larger. Warmer. A planet emerges from darkness. Blue. Green. White. Alive. Her ship slows.
INT. ISHARA'S SHIP - CONTINUOUS
Ishara stares at the world below. Her reflection in the glass—tall, pale, ancient—is the last image of the Engineers as they were. Her hand rests on the console. Beside it: a single crystalline container. Within it: her genetic signature. Her memory. Her apology.
ISHARA
(whisper)
I do not ask for forgiveness. I ask only that you become what I could not. Kind.
She releases the container. It falls toward the blue-green world. Ishara watches it descend. Cloud layer. Atmosphere. Horizon. Gone.
EXT. EARTH - PRIMORDIAL OCEAN
The container breaks the surface. Silent. Unseen. It descends through ancient water. No fish. No plants. No witnesses. It settles on the ocean floor. A seam opens. Genetic material—billions of years of Engineer evolution, compressed into a single act of hope—begins to disperse. The first cell divides. We do not see it.
EXT. SPACE - ISHARA'S SHIP
Ishara does not watch the ocean. She watches the horizon. The curve of the world. The endless blue. She does not smile. She does not weep. She simply... waits. Her ship has nowhere else to go.
TITLE CARD: 300,000 YEARS LATER
EXT. SAVANNA - DAY
Tall grass. Distant thunder. A heat shimmer on the horizon. A figure stands alone. Hairless. Upright. Eyes wide. She holds a stone. It is not a weapon. Not yet. It is simply... a stone. She looks at the sky. She does not know what she is. She does not know what she came from. She does not know what is coming. The wind moves through the grass. She walks forward.
TITLE CARD: HUMANITY - 300,000 YEARS AGO
TITLE CARD: ARU'NDI - THE PRESENT
EXT. ARU'NDI - LANDING ZONE - CONTINUOUS
The shuttles descend through the canopy. Jungle surrounds them—dense, alive, watching. Kai'sa steps onto the soil of Aru'ndi. The signal stops. Silence.
KAI'SA
(whisper)
She knows we are here.
KA'THAR
Yes.
A distant sound. Movement in the undergrowth. Something ancient, patient, hungry.
KA'THAR
And we are not alone.
Kai'sa looks at the jungle. Somewhere, deep within, the hive stirs. She has traveled across the galaxy. She has survived genocide. She has carried her daughter's carving across ten thousand light-years. And now she stands on a world that is not her own, facing creatures that are not her enemy, seeking answers from a woman who has been dead for millions of years. She does not know that she will never leave this world. She does not know that she will die here, centuries from now, old and scarred and respected, the mother of a new species of hunters. She does not know that her voice will echo through the Akri-Ha for ten thousand years, speaking to descendants she will never meet. She does not know any of this. She only knows that she is alive, and that she is not alone, and that somewhere in this jungle, a mother's voice still echoes.
KAI'SA
(to Ka'thar)
What do we do now?
He looks at her. His face is scarred, his mandible sheared, his eyes carrying the weight of everything they have lost.
KA'THAR
We survive. And then we learn.
He walks into the jungle. Kai'sa follows. The hive watches. The hunt begins.
