The Cognita Protocol

Welcome to Kestral City. Your life is in corporate hands.

The Cognita Protocol cover by JD Eells

Kestral, 2092. Once New York, now a city whose essential services run through corporate systems. Public institutions remain. Access is another matter. And the city’s best hackers are disappearing.

Start here · Kestral, 2092

The city was once New York.

War and climate damage left it dependent on the companies that rebuilt it. Government survived, but daily life runs through corporate systems: the train, the clinic, the water in your tap. An implant can restore a limb or sharpen a sense. It can also carry the credential that lets you work—and the license that can be switched off.

Who runs what?
Kaspar Corporation
Reconstruction finance, biometric verification, medical and civic records.
Pelagos Utilities
Water and power.
Aster Civic
Transit, housing, schools and benefits.
Morrow Civic
Policing, detention and prisoner transport.

Public ownership remains in law. The companies control the machinery.

Is artificial intelligence illegal?

Private ownership and use of independent AI is banned after major security disasters. Approved public systems remain under oversight; consumer tools have strict limits, and corporate research requires exemptions.

The distinction is independence: an intelligence able to act beyond those limits is contraband.

Why do implants need licenses?

The hardware may belong to you while its software depends on a paid license. A lost job can mean losing access to the device that lets you do that job. Repair shops, borrowed credentials and unlicensed upgrades fill the gaps.

Wealth buys seamless maintenance. Everyone else keeps older parts working.

From our decade to 2092 · The novel’s imagined history

How we get there.

Explore the timeline 2020s — 2092
  1. 2020s

    The first concessions

    Failing services, floods and forged records erode public trust. Companies offer dependable power and private identity checks in exchange for long contracts.

  2. 2030s

    A divided America

    Civil war fractures government and supply routes. Technology companies restore food deliveries, communications and essential services under emergency contracts.

  3. 2039

    The Unified Accord

    The worst fighting ends. Two national blocs share vital networks, but neither will let the other control them. Companies keep the contracts.

  4. 2044–2048

    New York becomes Kestral

    Kaspar Corporation forms in 2044 and finances reconstruction. In 2048, the charter approves Kestral as the new name for the old boroughs and neighboring communities behind shared flood defenses.

  5. 2060s

    A generation grows up connected

    Corporate schools, permanent identity records and enhancement contracts become ordinary life. Medical devices increasingly carry the credentials needed for work, travel and treatment.

  6. 2081

    Recognition breaks down

    The two national systems stop recognizing each other’s laws and identity records. A valid identity on one side may mean nothing on the other.

  7. 2082

    The Civil Disjunction

    Remaining public assets are divided among successor governments, charter cities and service companies. Temporary concessions become permanent.

  8. 2092

    The city you are entering

    Kestral still has a council and public courts. Companies operate the services those institutions depend on—and the systems that decide who gets access.

Technology, one layer at a time

The connected body.

Explore the technology beneath the surface. Select an illuminated implant—or its name—to learn what it does, how it connects, and where its limits begin.

Select an implant to explore its function
Kestral / Augmentation atlas04 systems
Hand-rendered X-ray-style head and shoulders. Four amber implants stand out against a cyan anatomical scan: the right-eye display, behind-ear jack, bone relay and cheek mesh.

Select an illuminated implant.

Fictional augmentation study · Hand-rendered scan

Sensory / Right eye

Retinal display

Function
Maps and instrument readings appear within the wearer’s field of view, without a handheld screen.
How it connects
The eye displays information obtained from connected equipment and other available sources.
Limitations
It cannot find evidence that has never been collected. A display is only as useful as the information supplied to it.

Interface / Behind the right ear

Neural jack

Function
A physical port connects the wearer to equipment within reach.
How it connects
A cable provides a direct interface with an external machine. That machine’s permissions and safeguards still apply.
Limitations
Connection does not grant access. Credentials, isolation and the risk of being traced remain part of the job.

Audio / Behind the ear

Bone-conduction relay

Function
Audio from a connected device travels through bone, keeping communication close and discreet.
How it connects
The relay carries the voice or signal of an external device. It is a communication channel.
Limitations
It is not an intelligence or a computer living inside the body. The source device remains separate.

Identity / Cheeks and jaw

Facial mesh

Function
The mesh shifts the cheeks and jaw toward a stored credential photograph. A matching face and borrowed credential can pass routine checks.
How it connects
The altered face works with the identity presented to a camera. Both parts need to agree.
Limitations
Facial contours do not change the blood vessels inside the eye. A retinal reader can expose the mismatch.
Other upgrades across the city

Hearing implants, pain-control stimulators and assisted limbs began as medical care. Stronger joints, sharper senses and improved concentration followed. These are other enhancement paths—not additional systems hidden in the scan above.

Every upgrade still needs maintenance. Infection, damaged nerves, depleted batteries and incompatible replacement parts remain part of life.

Worn equipment and connected tools

Adaptive camouflage is an external optical layer controlled through an implant connection and powered by its own battery. It changes reflected light to fool a camera briefly; it does not erase noise or pressure underfoot. Heat and sensory overload limit its use.

A neural recorder/writer is a separate handheld tool that can record and replay a brief sensory fragment through a physical port. The tool provides neither unrestricted access nor an implanted memory archive.
