Nexus Protocol

# Chapter 22: Nexus Protocol

Kira moved like someone who'd spent two years in a building where footsteps got logged.

Fast. Quiet. No wasted motion. The Underline's vendors didn't look at us twice—Neo Angeles had learned not to ask questions about people who walked with purpose and carried signal disruptors in their coat linings.

Sarah stayed on my left. Marcus ran parallel in the Ghost Net, feeding us camera rotations and one running commentary about how Kira's gait suggested "corporate assassin or very serious barista."

*Barista,* I sent back. *Nobody assassinates with that haircut.*

*You'd be surprised,* Marcus said.

We didn't go to Nexus headquarters. Not yet. Kira led us to a maintenance access under the maglev line—rusted door, biometric panel that looked dead until she pressed her palm and whispered a override code that made Sarah's eyebrows climb.

"Still active?" Sarah asked.

"Guest credentials lag forty-eight hours after termination," Kira said. "Nexus security assumes employees leave grateful. They don't plan for rage-quits."

"Relatable," I said.

The door opened on a service corridor that smelled like old electricity and new fear. Kira pulled up a holo-map—Nexus campus rendered in wireframe, layers stacked like a dungeon floor nobody had published a guide for.

"Fabrication is in Building C," she said. "Sublevel four. Public story: grief counseling AI for veterans' families. Private story: Project REvenant. Reanimate. Enhance. Vent. Deploy."

"They acronymed horror," Marcus noted. *Points for branding. Negative points for humanity.*

Kira ignored him—couldn't hear him, only us. "NeoLife's Elysium Engine taught the industry how to compress minds. Nexus stole the compression algorithms from the whistleblower dump you released. Cross's prison leak included partial specs. Venn bought three NeoLife defectors and told them to stop selling heaven and start selling hunters."

My implant pulsed. A flicker at the edge of vision—not a ghost, a echo of synthetic architecture, like my skull was tuning to a frequency I hadn't asked for.

Sarah noticed. "Zero?"

"Implant's excited. Bad sign."

Kira looked at me. "NX-7 batch implants were dual-purpose. Consumer neural link plus dormant handshake with REvenant substrates. Nexus seeded maybe two hundred thousand units in the outer districts. You're not special because you're a hacker. You're special because your glitch turned the handshake into vision."

"Comforting," I said. "Love being a corporate beta test."

We walked. The corridor opened into a vertical shaft with a ladder and an elevator that probably reported to someone who smiled too much.

Kira took the ladder.

Of course she did.

---

The safe room was three districts away—another abandoned box, but this one had heat and a working kettle. Sarah insisted on tea before war. Found-family rule number seven: hydrate or die stupid.

Kira dumped the chip's contents across three slates. Fabrication logs. Neural templates. Consent forms that were all blank signatures generated by legal AI.

I read the part that mattered.

Subject pools: deceased military personnel flagged in municipal death databases. Bodies not uploaded. Minds scraped from post-mortem neural scans performed at Nexus-owned clinics disguised as veteran health partners.

"They stole the dead," Sarah said. Voice flat. Scientist voice. The voice that meant she was holding back a storm.

"They stole soldiers," Kira corrected. "People who signed organ donor cards, not consciousness donor cards. REvenant maps their combat training into synthetic behavior trees. No memories. No names. Just tactics and obedience packaged as ghosts."

"Seven-Alpha," I said.

"Prototype hunter," Kira said. "Tests perimeter breach. Reports back. If successful, they scale."

Marcus had gone quiet. That was worse than swearing.

*They made weapons out of people who died in wars,* he said finally. *And they used our net as a firing range.*

"Why the Ghost Net?" Sarah asked. "Why not test on corporate sandboxes?"

Kira pulled up a comparison chart. "Sandboxes lie. Ghost Net is messy, distributed, defended by real minds with real reactions. If a hunter survives your quarantine, it survives battlefield consciousness networks. Venn's selling to private militaries and border states. NeoLife sold paradise. Nexus sells dogs that bite souls."

I tasted bile. "Tracing source—can we pin fabrication to Building C only?"

"Sublevel four, yes," Kira said. "But command and control is Building A, apex floor. CEO office. Venn runs live deployments from there. You crash fabrication, he routes production offshore in six hours."

"Classic raid mechanics," I said. "Destroy the spawn point and the boss teleports."

"Life is not a game," Sarah said.

"Life is absolutely a game. Bad UI, expensive DLC, permadeath for side characters."

She didn't argue. Progress.

We planned until the kettle boiled dry.

Phase one: trace Seven-Alpha's return path using my implant coupling—I'd become the bloodhound whether I liked it or not. Phase two: harden Ghost Net relays with Kira's insider knowledge of hunter protocols. Phase three: infiltrate Building C, steal REvenant core, publish to the same dead-man switches David had taught Sarah to love.

Kira listened. Didn't interrupt. When we finished, she said, "You're missing the fourth phase."

"Which is?"

"Survive Venn. He's not Cross. Cross wanted to be God. Venn wants to be arms dealer. He won't monologue about heaven. He'll delete you and invoice the cleanup."

"Cross tried to delete us too," Marcus said. *We're still here. Mostly.*

Kira almost smiled. "Cross underestimated grief. Venn doesn't underestimate anything. He measures it and sells the data."

---

Tracing took four hours and cost me a migraine that felt like my brain was grinding gears without oil.

I jacked into the Ghost Net's deepest diagnostic layer—where Elias's old code still hummed like roots under concrete. Marcus anchored me. Sarah monitored vitals. Kira fed Nexus handshake tables that made my implant sing wrong notes.

Seven-Alpha's path reappeared like a predator's trail in wet data.

Relay to relay. Jump. Jump. Always toward the outer band where settlements clustered—where real people lived who'd finally started trusting upload warnings.

"They're mapping us," I said. "Not just testing quarantine. Mapping population density for a coordinated strike."

Kira's face went tight. "Squad deployment. Timeline moved up."

"How long?" Sarah asked.

"Before dawn. Maybe sooner if Seven-Alpha reported success."

Marcus swore. *They'll hit the clinics first. Elias's nodes. The teaching hubs.*

He was right. I saw it in the trace—priority flags on community infrastructure, the places where we'd built honest afterlife instead of product.

"We harden now," Sarah said. "Zero, you run the patch. Kira, give us every hunter weakness you documented. Marcus, rally every coherent ghost who can hold a line. I'll contact settlement militia—yes, we have militia now, welcome to post-pyramid politics."

"On it," I said.

The next three hours were the kind of work that didn't look cinematic but kept people alive—script updates, relay reroutes, emergency authentication that locked out synthetic signatures unless they carried a human co-signature from the Ghost Net's council.

The council was new. Seven minds—some formerly trapped in Elysium, some born in the net like Elias's legacy routes—who voted on policy while Marcus made jokes and threatened to haunt anyone who voted for ads.

We patched. We prayed in the secular sense. We drank Sarah's terrible tea.

Dawn didn't come clean.

At 4:17 AM, Seven-Alpha returned with friends.

---

The attack didn't look like ghosts.

It looked like a DDoS made of faces.

Twelve signatures hit the outer relays simultaneously—military postures, blank eyes, designation chatter overlapping in my audio cortex like a corrupted voice chat.

*Designation Seven-Bravo. Target node: education hub.*

*Designation Seven-Charlie. Target node: medical archive.*

*Designation Seven-Delta. Target node: administrator signature Zero.*

"Flattering," I muttered, and slammed the new authentication protocol.

Three hunters bounced off the co-signature lock. Two got through on lag.

Marcus was everywhere at once—partial forms shoving packets, Elias's old crack routines opening emergency evac lanes for minds that weren't ready to fight. A grandmother ghost who'd died in a factory fire held a relay door closed with sheer stubbornness while Sarah's militia contact jammed physical antennas outside the settlement.

Kira worked Nexus counter-code like she was defusing her own past.

"Bravo's using a legacy handshake," she shouted. "Zero, your implant can spoof it—think of it as—"

"I know what it is," I said. "Same frequency as my glitch. Hold on."

I opened the channel I hated—the NX-7 backdoor. Let the synthetic architecture think I was one of them.

For a second, the hunters hesitated.

One second was enough.

Sarah hit the portable disruptor. Marcus kicked Bravo into a quarantine trap we'd named `please_hold.py`. The grandmother ghost screamed—not pain, effort—and the door held.

We lost Charlie.

Education hub partial collapse. Not destroyed—wounded. Data scattered but recoverable. Real damage. Real anger.

The hunters retreated in unison like they'd received an order from a player with a tactical overlay.

"They're reporting," Kira said. "Venn knows you're spoofing."

"Then we stop reporting," I said. "We go physical. Building C. Tonight."

Sarah looked at me. Tired. Fierce. "Infiltration with incomplete intel is how we get—"

"—how we got into a pyramid and kicked God. Yes. I remember."

Marcus flickered beside me. Solid enough to meet my eyes. *I'm not staying behind this time.*

"You run defense," I said. "They hit while we're inside, we're homeless."

*I hate when you're right.*

Kira packed the chip. "There's an maintenance tunnel from the Underline to Building C sublevel two. Freight credentials. I can get us to the door. Past that, it's you."

"Past that," I said, "it's a heist."

Sarah checked the disruptor charge. "Past that, it's war."

The rain stopped. Neo Angeles kept glowing anyway.

I pulled up the Nexus campus map one more time. Building A apex. Building C sublevel four. Two objectives. One night. No save points.

Cross had been a god raid.

Venn was a logistics raid.

Harder in some ways. Easier in others—gods wanted worship; arms dealers wanted quarterly growth, and quarterly growth had vulnerabilities.

"Gear up," I said. "Marcus, tell the council if we don't ping in six hours, publish everything on Kira's chip and burn Nexus public."

*Six hours,* Marcus said. *Speedrun strats.*

"Don't die," Sarah said to both of us.

"Don't science without me," I said.

She bumped my shoulder. Found family. Minimal. Effective.

We moved.

The Underline swallowed us again. Kira's credentials opened the freight tunnel. The air tasted like rust and old maglev oil and the future trying to be worse than the past.

My implant hummed—glitch awake, hungry, afraid.

Six months after we'd made the Ghost Net honest, someone was selling counterfeit souls with military serial numbers.

I was done being a beta tester.

Time to crash the server.

Sarah messaged the archivist network David had trusted—*prepare shelters, Nexus may escalate*. Marcus messaged the council—*no hero solo, hold doors*. I messaged nobody and everybody in the Ghost Net: *We're still here. We're not prey.*

The net pinged back before we reached the tunnel entrance.

Thousand pings.

Not paradise.

Not weapons.

Neighbors.

That was enough to walk into the dark with.
