# The Dojo Underground: Where Runners Sharpen Their Edge

## Hidden in Plain Sight

## What a Dojo Is

The word is borrowed. The concept is not.

A dojo — in the runner economy of GLMZ — is an unlicensed training facility where freelance operators practice their unique abilities without corporate surveillance, legal scrutiny, or the attention of anyone who might use that knowledge against them. They are gyms for people whose skills are illegal. Schools for trades that don't appear in any curriculum. The places where a netrunner stress-tests their intrusion deck against live defenses, where a combat specialist drills augment-assisted CQB at full speed, where a poisoner learns dosage on synthetic tissue targets, and where a face practices their lies on people paid to catch them.

Dojos are not academies. There are no diplomas. There are no semesters. There is a space, an instructor (sometimes), equipment (always improvised, often stolen), and a community of operators who need to stay sharp between contracts. You train until you're good enough or you stop coming because you're dead.

## How You Find One

You don't find a dojo. A dojo finds you. Or more precisely — you prove that you're worth finding.

Every dojo has a signal system. An invisible language of markers that identifies the entrance to people who know what to look for and is meaningless to everyone else:

**Glyph Systems** — The most common. A specific sequence of characters — letters, numbers, symbols — scratched, painted, or projected in a location that only makes sense if you know the cipher. The sequence changes weekly. The cipher is shared through runner networks, never written down, never transmitted digitally. If you see `Φ7.Ξ.4` scratched into a dumpster behind a noodle shop and you know that this week's Shelf cipher maps Ξ to "basement," you know there's a dojo entrance in the basement of the noodle shop. If you don't know the cipher, you see vandalism.

**Augment Signals** — Invisible to the naked eye. Some dojos broadcast low-power signals on deprecated BCI frequencies that augmented runners detect as a faint sensation — a warmth behind the ear, a taste of copper, a visual flicker in the corner of the HUD. The sensation is distinctive enough that you recognize it once you've been taught what to feel for. Unaugmented people experience nothing. Corporate security scanners don't monitor deprecated frequencies. The signal is hiding in the electromagnetic noise of the city.

**Physical Tells** — Architecture-based. A door handle that's been replaced with a specific model. A window with a crack in a pattern that isn't random. A fire escape where the third rung has been bent 15 degrees to the left. A potted plant in a window that isn't a real plant — it's a 3D-printed replica, and the specific model number visible on the pot's base encodes the entry code. You learn the tells from someone who already trains there. Nobody learns them from a manual.

**E.L.F. Guides** — The rarest and most unsettling. Some dojos are marked by E.L.F.s — tiny digital spirits that inhabit the infrastructure around the entrance and subtly guide runners toward it. Your nav augment suggests a route that takes you past the door. Your optical implant's focus lingers on a specific wall for 0.3 seconds longer than it should. Your sense of direction pulls you left instead of right. You don't consciously notice. You just... arrive. Whether the E.L.F.s are placed there deliberately or choose to help on their own is a question nobody has answered.

## What's Inside

Dojos range from a cleared-out basement with a punching bag to multi-level facilities with specialized training environments. The quality depends on who runs it and who pays for it.

### Combat Dojos

The most common type. Reinforced spaces where operators can drill at full augmented speed without destroying the building or alerting neighbors.

- **Kill Houses** — Reconfigurable room layouts for close-quarters-battle training. Walls on rails. Doors that open wrong. Corners designed to teach you that corners kill. Some use holographic targets. The good ones use drones that shoot back with stun rounds.
- **Augment Ranges** — Spaces calibrated for testing augmented capabilities at full output. A prosthetic arm that can punch through concrete needs a space where punching through concrete is expected. Reinforced walls, ablative surfaces, impact sensors that measure force output. Runners test their chrome here because testing it on a job means testing it when failure is death.
- **Sparring Pits** — Exactly what they sound like. Augmented fighters against augmented fighters, with a referee whose only job is preventing kills. The best pits use medical monitoring — each fighter's BCI streams vitals to a medic station that can call the match before someone's heart stops. The worst pits don't have referees.

### Netrunner Dens

Shielded rooms where hackers practice intrusion against sandboxed network environments. The sandbox replicates real corporate network architecture — Axiom's security protocols, Tessera's encryption layers, Sterling-Nakamura's financial firewalls — in a contained environment where getting caught means rebooting instead of prison.

The best dens run **live capture** — they intercept and replay actual corporate network traffic (illegally captured) so the netrunner trains against real-world patterns, not simulations. A den running live Axiom traffic is worth ten times one running simulated traffic because Axiom's security AI adapts in ways simulations can't replicate.

### Face Studios

Where social engineers practice manipulation, deception, and persuasion. These look like ordinary rooms — a table, chairs, maybe a bar. The training is the conversation. An instructor plays a role: corporate executive, security guard, grieving widow, angry gang leader. The student must achieve an objective through words alone. No augments. No hacking. No violence. Just the ability to make someone believe something that isn't true, agree to something they shouldn't, or reveal something they swore to protect.

Face training is the most psychologically demanding dojo discipline because it requires you to understand people well enough to manipulate them, and understanding people that well tends to make you like them, and liking people you're learning to exploit creates a cognitive dissonance that either makes you better at your job or makes you quit.

### Tech Labs

Workshops where riggers, demolitions experts, and tech specialists build, modify, and test equipment. Drone operators fly in caged environments. Demolitions experts practice charge placement on condemned structures (arranged through connections with Palladian Construction's demolition division, which quietly rents condemned buildings to dojo operators for exactly this purpose). Augment technicians practice installation and repair on synthetic tissue platforms that simulate human biology without being human.

### Geneware Gyms

The newest category. Spaces where operators with combat geneware train their biological modifications — venom delivery, toxin resistance, enhanced reflexes, prehensile tail combat (yes, this is a real discipline), and the increasingly popular practice of chromatophore-based active camouflage training, where operators with chameleon geneware learn to control their skin patterns for stealth.

## The Instructors

Dojo instructors are retired runners. Or runners who got too old. Or runners who got too injured. Or runners who realized they were better at teaching than doing. The common thread: they survived long enough to have something to teach, and they chose to teach it instead of dying on one more contract.

Instructors are not employees. They don't get salaries. They take a cut of the dojo's income (which comes from membership fees, usually Φ200-500/month) and they get first-refusal rights on any contract that comes through the dojo's network. The best instructors are living legends — names that runners speak with respect and fear. The worst instructors are people who survived through luck and teach habits that will get their students killed.

The instructor-student relationship in a dojo is the closest thing the runner economy has to apprenticeship. An instructor who vouches for a student is staking their reputation. A student who embarrasses their instructor is done — not just at that dojo, but in the network that dojo connects to.

## The Economics

Dojos operate in the gray economy. They are not licensed businesses. They don't pay corporate taxes. They don't appear on any registry.

Revenue comes from:
- **Membership fees** — Φ200-500/month for regular access. Premium dojos with live-capture netrunner dens or military-grade kill houses charge Φ1,000-2,000/month.
- **Equipment rental** — Specialized gear that individual runners can't afford to own. Intrusion decks, demolition equipment, sparring drones, synthetic tissue platforms.
- **Contract brokerage** — Many dojos serve as informal job boards. Fixers post contracts. Runners take them. The dojo takes 5-10% of the contract value for the connection.
- **Side bets** — Sparring pit fights attract spectators. Spectators bet. The dojo takes a cut.

Expenses:
- **Rent** — The space itself. Most dojos lease from landlords who don't ask questions, in buildings whose owners are dead, missing, or corporate shells.
- **Equipment maintenance** — Kill house walls need replacing. Sparring drones need rebuilding. Sandboxed networks need updating as corporate security evolves.
- **Medical** — Injuries happen. Every dojo above basement-tier has a street doc on retainer.
- **Protection** — Someone always wants a cut. Depending on the neighborhood: Iron Lotus, local gangs, corrupt security officers, or the building's own E.L.F. (yes, some dojos pay offerings to the digital spirit inhabiting their infrastructure, and yes, the infrastructure works better when they do).

## Famous Dojos of GLMZ

**The Crucible** — The Shelf's most respected combat dojo. Located in a converted water treatment facility. Run by a retired street samurai named Adaeze Volkov-Tessari who lost both arms on a contract and now teaches with prosthetics that she deliberately keeps at baseline specification to prove that skill matters more than chrome. Membership: ~200 active fighters.

**Blackbox** — The Circuit's premier netrunner den. Hidden inside a functioning data center (the irony is deliberate). Runs live-capture traffic from four major corponations. Membership is by invitation only and requires passing an intrusion test that 80% of applicants fail. Run by a collective of five netrunners who rotate the admin role monthly.

**The Mirror** — The only known face studio that trains both runners AND corporate operatives (in separate sessions, obviously). Located above a teahouse in the Narrows. The instructor — known only as Glass — has never been seen without a different face. Whether this is geneware, holographic projection, or just very good makeup is part of the mystique.

**Sublevel 6** — An underworld combat dojo built into a collapsed subway station. Specializes in close-quarters fighting in confined, dark, unstable environments — the specific conditions of underworld operations. The ceiling leaks. The floor is uneven. The lights fail at random intervals. This is not a bug. Students who complain are invited to leave.

**The Greenhouse** — The only known geneware gym in GLMZ. Located in Old Harbor, in a building whose upper floors are open to the sky. Specializes in training operators with radical body modifications — tail fighters, wall-climbers with gecko adhesion, operators with venomous glands who need to learn dosage control. The instructor, a woman named Priya Castillo-Obumseli, has more geneware modifications than anyone in the Shelf has catalogued and moves in ways that human skeletal structure shouldn't allow.
