[Location: Project Zero - Medical Bay] [Time: Subjective Year Zero. 100 Years Ago.]
"We call it the Ouroboros Drive," Aris said.
We were standing in the medical wing. In the center of the room, resting on a velvet-lined surgical tray, was a mechanical arm.
It wasn't the rugged, tattered, matte-black prosthetic I would wear in my loops. It was pristine. Gleaming silver, interlaced with intricate blue energy veins and delicate fiber-optic nerves. It looked less like a weapon and more like a piece of high-end jewelry.
"It is a localized temporal anchor," Vesper explained. She was standing next to the tray, refusing to meet my eyes. Her hands were trembling slightly. "It connects directly to your central nervous system. When your heart stops—when you experience biological death—the drive triggers a micro-singularity."
"It sends my consciousness back," I said, repeating the briefing. "Back to a fixed point in time. A save state."
"Theoretically," Vesper corrected. "It has never been tested on a human. The data load is immense. It transfers the memories of your death back into your past brain. The psychological trauma could shatter your mind instantly."
"I can handle it," I said. I was eighteen. I thought I was invincible.
"There's something else, Caelum," Dr. Aris said. His voice was cold, professional. "The Drive requires a massive neural highway to function. The human body does not have the bandwidth to support the data transfer. We cannot simply implant a chip."
I looked at the silver arm on the tray. Then, I looked at my own left arm. My real, flesh-and-blood arm.
The realization hit me like a physical punch.
"You have to cut it off," I whispered.
"At the shoulder," Aris confirmed. "The Ouroboros must replace a major limb to interface correctly with the spinal column. We need your consent, Cadet. Once we begin the surgery, there is no going back. You will no longer be entirely human."
The room went dead silent. The hum of the medical monitors felt deafening.
I looked at my hand. The hand that used to throw baseballs on the farm. The hand that gripped the flight yoke in the simulator.
Then I thought of the news reports. The millions dead on the Mars colonies. The Algorithm ships darkening the sky.
"If I do this," I asked, my voice shaking. "Will it save them?"
"You will be the shield that protects humanity," Aris said solemnly.
I nodded. I unbuttoned my cadet jacket and let it drop to the floor. "Do it."
Aris nodded to the medical team. "Prep him for anesthesia."
As they strapped me to the surgical table and placed the IV in my right arm, Vesper stepped up beside me. She wasn't holding her clipboard anymore.
"Caelum," she whispered. Her eyes were wet.
"Hey," I gave her a weak smile. "It's just an arm. You're giving me a cooler one, right?"
"I'm sorry," she said, her voice breaking. "I'm so sorry."
"Don't be," I said as the anesthetic began to burn through my veins, making my vision blurry. "Just... promise me you'll fix it if it breaks."
Vesper reached out and gently took my right hand. Her skin was warm.
"I promise," she whispered.
The lights above me flared bright white, and then faded into absolute black.
The first cut was made. And the Boy Who Wanted to Fly died on that table, replaced by the Weapon that would bleed for eternity.
