Directive Classification: NIVEUS PROTOCOL – Strategic Containment
Following the harrowing encounter inside the Vault, ONI initiates NIVEUS PROTOCOL, designating a 500-kilometer radius around the Vault site on Europa as a High-Risk Strategic Containment Zone.
This region is sealed off from all traffic—military, civilian, scientific, and corporate.
UEG publicly declares:
"Seismic instability and magnetic anomalies have made the region unsafe for continued development."
Outside this black zone, activity on Europa continues under intense scrutiny:
Horizon Industries is forced to divert nearby terraforming operations.Mining colonies are relocated further west.ONI quietly installs orbital interdiction satellites camouflaged as geological survey units.The rest of the moon remains populated and productive, but under the shadow of the silent quarantine.
The crystalline Ceph sample—AE-Δx_313—is stored deep within ONI's Blackvault facility on Mars.
Initial findings:
Reacts to neural activity within 4 meters.Emits encoded frequency modulations, likely not intended for humans.Core clusters contain biometric resonance patterns—possibly Ceph language or command data.ONI refrains from any reactivation attempts.
Instead, they pursue:
Neural firewall implants to protect minds from potential Ceph influence.Subspace dampening tech to mask human presence near similar artifacts.Synthetic resonators to mimic harmless signals and reduce Ceph alertness.The local colonies near the exclusion zone begin to speculate.
Rumors of a "black project gone wrong" circulate.
A few whistleblowers go missing.
One message makes it to the SolNet under a false ID:
"They found something under Europa's ice. Something not dead. Something patient."
UEG passes Europa Strategic Oversight Act, granting ONI full jurisdiction over the exclusion zone without civilian oversight.

Date: September 2, 2193
Location: ONI Strategic Command, Earth – Black Room Theta**
The room was deep beneath Argyre Base, shielded from every kind of surveillance known to humanity. No AI. No digital records. Just voices, hard walls, and harder men and women.
A grainy holofeed flickered on, pausing on a frame of the black-suited Nanosuit operatives recorded during the Europa vault operation. The footage from the recovered blackbox was brief—distorted—but clear enough to confirm the technology was not UNSC, and far too advanced for any known civilian group.
"They're watching us as closely as we're watching them," Kepler growled.
"We waited too long."
Halbek stood, arms crossed.
"The suits are biological-integrated. Unmarked. Efficient. They're using data we thought lost with Grayson's death—or buried in Atlas."
"This Enclave is real, operating with complete autonomy and technical sophistication. Their command structure is decentralized. Off-world. They're ghosts."
She walked to the projection of the Europa Vault exclusion zone.
"And they're Ceph-curious."
Thorne added:
"Their agents didn't destroy the infection. They stabilized it. They didn't even touch the Helldiver team. That's control… or long-term investment."

Operation LURENET
Halbek proposed the operation's spine:
"We leak false telemetry. Ceph energy signals. Simulated surge pulses. Make it look like something beneath the Vault is changing. Draw them in."
Commander Vara nodded:
"Their black suits are curious. Tactical. They'll want a look. We make the signs too good to ignore. Feed it across buried networks they already tap into."
"And then?" asked Kepler.
"We let them come," Halbek said calmly. "And we take them alive."

Blackwatch teams with anti-integration cages (tech adapted from the Helldiver recovery mission).Drones seeded into the zone with synthetic Ceph radiation patterns.Submerged traps disguised as geological equipment.Neural net scramblers to block Nanosuit comms once activated.Helldiver forward teams to act as contingency cleanup."We don't kill them. We study them," said Dr. Thorne.

Europa — September 5, 2193
Site Theta-Vault Echo – Quarantine Zone Perimeter
The wind over Europa's ice plains howled like a haunted thing, screaming across a wasteland sealed by fire and memory. Beneath that lifeless crust, frozen deep in kilometers of glacial pressure, lay the Vault.
It hadn't stirred since the Helldiver incursion. Officially, the United Nations Directorate had declared the site inert—dormant and sealed. Europa was quarantined. No-fly zones. Automated kill-sats in orbit. Even the UNSC had been told the vault was no longer a concern.
But ONI never truly seals anything.
Inside a remote black site orbiting Ganymede, Vice Director Halbek stood in the dim light of a sealed war room. Holo-screens flickered with telemetry from Europa's under-ice sublayers—old vault sensor ghosts and new, artificial noise injected into the silence.
At the center of it all: a transmission. Engineered by ONI's best cryptologists, laced with fragments of the Ceph signal first encountered during the original Aurora-1 descent.
"Let them think we made a mistake," Halbek said. His voice was calm, assured.
"Not a threat. Not an emergency. A curiosity. That's how you hook someone like Hargreave."
The signal was a puzzle—broken, recursive, layered with just enough exotic entropy to mimic something awakening.
A trap disguised as opportunity.

September 13, 2193 – Europa, Quarantine Zone
They arrived silent and unseen.
Ghost Team: four Enclave operatives clad in sleek, near-silent Nanosuit prototypes, dropped from orbit in stealth-pods that rode ice-penetrating rail spires into the crust. They slid through abandoned ONI tunnels, crawling through half-frozen ducts and black corridors that hadn't seen a human in years.
No lights. No signal. Only instinct and code.
The suits whispered telemetry back to their handlers.
No movement. No heat. No resistance.
Exactly as expected.
--------------------------------------------------------------------------------------------------------------
Site Theta-Black, Sublevel 3 – ONI Observation Command
Director Halbek stood once more in silence, arms behind his back as a dozen holo-feeds tracked the Ghosts' movements through the ice.
"Four of them," an analyst reported. "Just as projected. No support net. They're confident."
"And predictable," Halbek said softly.
Around him, the walls of the black site pulsed with quiet life. Dozens of ONI operatives with Helldivers support , armed to the teeth, were positioned at intercept points kilometers wide—none visible, none threatening. Just… watching.
Waiting.
"Let them go deeper," Halbek murmured.
"They'll show us everything they know—before we take them."
The trap was sprung.
Now came the patience.
