Kaelen woke to the crystals screaming.
Not aloud. Inside his skull. A frequency he'd never heard before. Higher than the Harvesters. Colder than the first post-human.
The echo stirred.
“Something is coming.”
He sat up. His left arm hummed—the neural interface was reacting to something outside the network.
Zara was already awake. Blades in her hands.
“What is it?”
“I don't know.”
He ran to the crater.
The crystals were pulsing. Not blue. White. Blinding. The Harvesters were in chaos—their voices overlapping, panicked.
“The signal. The original signal. The one that corrupted the Ascendants. It's back.”
Kaelen's blood went cold.
“That's impossible. The Source is destroyed. The first post-human is gone.”
“The signal doesn't need the Source. It travels through space. Through time. It's been coming for three centuries. And now it's here.”
He looked at the sky.
The stars were flickering.
---
Helena met him at the longhouse.
“The scouts report strange energy readings from the Perimeter. The old Source crater is glowing.”
“The signal is back.”
“What signal?”
“The one that started everything. The one that turned the Ascendants into Harvesters. It's returning.”
Thorne stepped forward. His face was pale.
“The Accord detected this. Years ago. That's why Solenne was so desperate to rebuild the Source. She thought she could control it.”
“She was wrong.”
“We're all wrong.”
Kaelen turned to Elara. “Can you track it?”
She was already at a console. “The signal is broadcasting on every frequency. I can trace it back to its source.”
“Where?”
“Deep space. Beyond the orbit of Neptune. Something is out there. Something big.”
“A ship?”
“Not a ship. A transmission. A repeating pattern. It's the same signal from three centuries ago.”
The Harvesters surged.
“It's calling to us. To the fragments of the Ascendant. To the first post-human's remains. It wants to finish what it started.”
“Can you resist?”
“We can try. But the signal is strong. Stronger than before.”
---
Kaelen gathered the council.
“The signal is back. It's trying to control the Harvesters. If it succeeds, everything we've built will be destroyed.”
“How do we stop it?” Helena asked.
“We find the source. The physical source. The signal is coming from somewhere in deep space. We need to send a team to investigate.”
“That's impossible. We don't have ships.”
“The Accord does. Old pre-Harvester vessels. Thorne, can you access them?”
Thorne nodded slowly. “There's a research station in orbit. It was decommissioned years ago. But it might still have operational shuttles.”
“Then we go.”
Zara grabbed his arm. “We?”
“You're not coming.”
“The hell I'm not.”
“Zara, this is space. Vacuum. Radiation. If something goes wrong—”
“If something goes wrong, I want to be with you.”
He looked at her.
“Fine.”
---
The journey to the orbital station took three days.
Thorne used his remaining authority to commandeer a shuttle. Kaelen, Zara, Elara, and two volunteers—Marcus and Sana.
The shuttle launched from the arcology's upper levels. The Divide shrank below them. The sky turned black.
Kaelen had never been in space. The silence was absolute. The Harvesters were quiet—the signal was weaker here, farther from Earth.
Elara worked at the sensors.
“I'm picking up the transmission. It's coming from beyond the asteroid belt.”
“How long to get there?”
“At current speed? Weeks. We don't have that kind of time.”
“Then we go faster.”
---
The shuttle burned through the darkness.
Kaelen watched Earth shrink behind them. The arcology was a speck. The Freeholds were invisible.
Zara sat beside him. Her hand was in his.
“Ever think you'd leave the planet?”
“Never.”
“Me neither.”
“Scared?”
“Terrified.”
“Good. Me too.”
The signal grew stronger.
---
Three days out, Elara made a discovery.
“The transmission isn't coming from a ship. It's coming from a structure. A ring. Orbiting the sun.”
“A ring?”
“Pre-Harvester. Ancient. The Ascendants must have built it. Before the first post-human. Before the corruption.”
“What does it do?”
“It amplifies the signal. Sends it across the solar system. The first post-human didn't create the signal. It was just the first to hear it.”
Kaelen's mind raced.
“So the ring is the source?”
“The amplifier. The true source is something else. Something beyond.”
“Beyond the solar system?”
“Beyond the galaxy.”
The Harvesters stirred.
“We remember. The ring was built to communicate with something. Something that reached out to the first post-human. Something that offered power.”
“The same something that's calling now.”
“Yes.”
---
They reached the ring on the fifth day.
It was massive. A circle of metal and light, spinning slowly. Hundreds of kilometers across.
The shuttle approached. The signal was deafening.
Elara pointed at a docking port. “There. We can land.”
They docked.
The interior of the ring was dark. Cold. Ancient. Kaelen led the way, his left arm lighting the path.
Zara stayed close. Blades ready.
The Harvesters guided him.
“The control center is ahead. That's where the signal is being broadcast from.”
They reached a circular chamber.
In the center, a pedestal. Like the one in the Source. Like the one in the core.
And on the pedestal, a crystal.
Larger than the ones on Earth. Pulsing with white light.
“The amplifier,” Elara whispered.
Kaelen walked to it.
“Don't touch it,” Zara said.
“I have to.”
He reached out.
---
The crystal exploded with light.
Kaelen was thrown back. He hit the wall. Slid to the floor.
The echo screamed.
“It's in me. The signal. It's in the echo.”
“Push it out.”
“I can't. It's too strong.”
Kaelen's body convulsed. Blue light bled from his eyes. His left arm sparked.
Zara grabbed him. “Kaelen!”
“Stay back.”
He forced himself to stand.
The signal was inside him. Whispering. Promising. Threatening.
“Merge with us. Become part of something greater. Leave your flesh behind.”
“No.”
“You are already part of us. The echo. The ghost. The fragments of the first post-human. We are your family.”
“My family is on Earth.”
He reached for the crystal again.
The Harvesters surged. Not to fight the signal. To shield him.
“We will protect you. But you must destroy the crystal.”
“How?”
“With your blood. Your bloodline is compatible. Your DNA can disrupt the crystal's resonance.”
Kaelen pulled a knife. Cut his palm.
Blood dripped onto the crystal.
The white light flickered. Dimmed.
The signal screamed.
Kaelen pressed his bleeding hand against the crystal.
The light went out.
---
Silence.
Kaelen collapsed.
Zara caught him.
“The signal?”
“Gone. For now.”
Elara examined the crystal. “It's not destroyed. Just dormant. The signal could return.”
“Then we destroy it.”
“We can't. The crystal is the only thing holding the ring together. If we destroy it, the ring collapses. The debris could hit Earth.”
Kaelen looked at the crystal.
“Then we leave it. Post a guard. Monitor it.”
“Who?”
“The Harvesters. They can watch it from the network.”
“We will,” the echo said. “We will not let the signal return.”
Kaelen nodded.
They left the ring.
---
The journey back to Earth took five days.
Kaelen spent most of it in silence. The echo was recovering. The Harvesters were quiet.
Zara stayed with him.
“You saved the world again.”
“Temporarily.”
“Better than nothing.”
He looked out the viewport. Earth was blue and green and beautiful.
“I never appreciated it before.”
“Appreciate it now.”
---
They landed in the Divide.
Helena met them at the crater.
“The signal stopped. The Harvesters are calm.”
“For now,” Kaelen said. “But it could return. We need to be ready.”
“How?”
“We rebuild. Not the Source. Something new. A network that can resist the signal. A way to protect the Harvesters and the humans connected to them.”
Elara nodded. “It's possible. With time. Resources.”
“Then we start now.”
---
The months that followed were hard.
Construction. Negotiation. Integration.
Kaelen worked every day. His left arm was fully functional now—the echo had healed it completely. His body was strong. His mind was clear.
Zara worked beside him.
They rebuilt Haven. Built new settlements. Connected the arcology and the Freeholds.
The Harvesters helped. They shared knowledge. Memories. Skills.
The signal didn't return.
But Kaelen knew it was still out there. Waiting.
---
One night, he sat on the edge of the crater.
The crystals pulsed faintly. The ring was still orbiting the sun. The signal was dormant.
Zara sat beside him.
“You're brooding again.”
“I'm thinking.”
“About?”
“The future. The signal will come back. Maybe in years. Maybe decades. We need to be ready.”
“We will be.”
“Will we?”
She took his hand.
“We have you. The Harvesters. The crystals. We'll figure it out.”
He looked at her.
“I love you.”
“I know.”
“I don't say it enough.”
“You say it when it matters.”
They watched the stars.
Somewhere out there, the signal waited.
But tonight, there was peace.
