Gearball Basics – Brass & Bone Investigations

Origins

The sport grew out of informal competitions between rival guild crews on the Western Industrial Slope — foundry workers and structural fabricators settling disputes and pride with a scavenged sphere and whatever platforms they could rig after hours. That origin is still visible in how the league is organized: teams are guild-sponsored rather than civic, which means Gearball carries labor politics the way the Opera House carries civic prestige.

Gearball is Gearhaven’s own sport, born of guild rivalry rather than civic ceremony, and it looks the way the city looks: three tiers, one rising above the other, with the easiest thing to do at the bottom and the thing worth cheering for at the top. A match is two hours long. Explaining it to someone who has never seen a lift platform vent steam under a man’s boots takes rather longer, which is the purpose of this document.

The Arena

A Gearball pitch is built in three tiers, mirroring the city’s own elevation logic: the Ground (a packed-earth and brass-plate floor where most physical contact happens), the Span (a mid-level lattice of catwalks and platforms roughly fifteen feet up), and the Crown (the highest goal tier, reserved for the most difficult scoring attempts).

Spectator seating follows the same pattern Gearhaven applies to everything else — glassed, heated galleries at Crown height for those who can afford them, open standing terraces at Ground level for everyone else. A Gearball match is, among other things, a two-hour demonstration of the fog line rendered in architecture.

The Core

The core is a weighted brass sphere, roughly the size of a large cabbage, heavier than its size suggests — deliberately so, to punish sloppy handling and reward technique over strength. It cannot be thrown overhand (a rule dating to an early-league injury that guild elders still argue about) and must be advanced by controlled rolls, low tosses, or platform-assisted lifts.

Goal Rings

Three rings per end, one per tier — Ground, Span, and Crown — each suspended and swinging slightly on gimballed mounts, which is part of the difficulty. A Ground goal scores low and is the easiest to attempt; a Crown goal, contested in the air off a lift platform, scores highest and draws the crowd to its feet. A team that scores across all three tiers in a single half earns what’s called a Full Ascent, a rare enough feat that it’s noted in league records by name.

Teams and Positions

Nine to a side. Three broad roles: Grounders, who control the core at floor level and set up plays; Spanners, who work the mid-tier catwalks and act as the link between the ground game and the air game; and Liftmen, who ride the steam platforms up to attempt Crown goals and are, by guild tradition, usually the smallest and lightest players on the roster — weight matters more than height when a platform’s lift capacity is fixed.

Grounders (3)	Floor-level ball control, formation setup, and the sport’s only legal contact zone. The position most likely to end a match with a bruised shoulder and no complaints about it.
Spanners (3)	Work the catwalks. Receive from Grounders, feed Liftmen, and defend the Span ring. The position with the most running and the least glory.
Liftmen (3)	Ride the platforms for Crown attempts. Selected for weight as much as skill — a licensed platform has a hard capacity, and every extra pound is speed and height the team doesn’t get.

The Lift Platforms

Each platform is licensed and gauge-stamped by an inspector before a match, rated for a maximum burn pressure that determines how fast and how high it can carry a Liftman. This is the sport’s central mechanical tension: more pressure means more lift and more speed to the Crown ring, but pressure above the licensed rating is illegal — “excessive mechanical enhancement,” in league language — and a platform found running hot after a match is confiscated and its guild fined, sometimes suspended for a season.

Pre-match inspection is its own small ceremony, usually performed by a retired engineer in view of both benches, gauge held up for the crowd to see. It is, not coincidentally, one of the few moments in Gearhaven where a working-class tradesman’s word is treated as final and unchallengeable.

Match Day Procedure

A match opens with the Drop: the head referee — known on every pitch as the Whistle — sets the core between two opposing Grounders at the center Ground ring and steps back. Everything else follows from there.

Match length	Two 40-minute halves, running clock, with a break at midpoint for platform re-inspection.
The Ascent Clock	A separate 15-second clock starts the moment a Liftman engages a platform for a Crown attempt. Miss the window and the attempt is dead, ring returns to play — it’s the one part of the match where the crowd counts out loud.
Substitutions	Rolling for Grounders and Spanners. A Liftman substitution requires a platform reset, which costs the team time — swapping your best Liftman mid-drive is a real decision, not a free one.
Full time	Signaled by the Long Horn, a single low steam-whistle blast audible across every tier.
Sudden Ascent	If the match is level at full time, a 10-minute extra period is played; first score of any kind wins. Still level after that, it goes to a Crown-goal shootout — three Liftmen a side, one attempt each.

Scoring and Match Structure (Summary)

Ground goal	1 point — the easiest attempt, contested at floor level.
Span goal	3 points — mid-tier, off the catwalks.
Crown goal	5 points — highest tier, contested in the air off a lift platform, on the Ascent Clock.
Full Ascent	A team that scores at all three tiers within a single half. Rare, and recorded in league history by name rather than just by score line.

Offensive and Defensive Play

The rules describe what’s legal. This is what teams actually do with it — the standing playbook every guild coach works from, with local variations. None of the following is a formal rule; a team is free to invent its own approach, and several have. But every announcer, and every opposing bench, is expected to recognize these when they see them.

Advancing the Core

A possession starts wherever the core changes hands and, in theory, has three destinations: a quick Ground goal, a Span goal off the catwalks, or the full climb to a Crown attempt. In practice most possessions are decided in the first few seconds, by whether the Grounders choose to push or to build.

Play	What it is	When it’s used
The Climb	The base playbook: a deliberate, tier-by-tier advance — Grounders establish control, feed a Spanner, who feeds a Liftman for a Crown attempt. Slow, safe, and the only realistic route to a Full Ascent.	Default approach; favored by teams built for patience (Brightmere, East Hill).
The Slope Rush	A fast, low advance that never leaves the Ground — short rolls and quick exchanges between Grounders, aimed at a 1-point goal before the defense sets. Trades points for tempo.	Trailing late, or against a defense still resetting from the Drop.
The Relay	Quick Spanner-to-Spanner passing along the catwalks, designed to move the core across the Span faster than defenders can shift to match it.	Breaking a set Span-marking defense.
The Feed	The handoff from a Spanner to a Liftman just before the Liftman engages the platform — timed tightly, since the Ascent Clock starts the instant the Liftman steps on.	Every Crown attempt starts here; the timing of the Feed is what separates a clean Ascent Clock conversion from a rushed miss.
Twin Ascent	Two Liftmen engage platforms for the same Crown ring at once — one is usually a decoy. Forces the defense to choose who to contest, but doubles the team’s exposure to a Crown-crowding call.	High-value, high-risk; more common late in a half when a team needs a Crown goal and is willing to risk the foul.
The Wedge	A blocking formation — two Grounders shield the one carrying the core through the sport’s only legal contact zone.	Standard escort for any Ground-level push through a packed defense.

Stopping the Advance

Defense in Gearball is mostly about denying tiers rather than denying the ball outright — a team that can’t stop a possession at Ground will try to make the Span expensive, and a team that can’t do that will contest the Crown attempt itself, which is the most dangerous and most spectator-friendly option available to them.

Play	What it is	Notes
Ring Wall	Grounders collapse in front of their own Ground ring rather than pressuring the ball carrier — concedes ground possession to protect against the cheap 1-point goal.	A defensive team down to the wire on points will sit in a Ring Wall and dare the offense to commit to a slower Climb.
Span-marking	Man-to-man coverage on the catwalks — each Spanner tracks an opposing Spanner rather than the core itself, to choke off the Feed before it happens.	The Relay exists specifically to beat this.
The Drop-back	A fast collective retreat from Span to Ground the instant possession is lost — the moment of transition is the sport’s most common scoring lapse, and the Drop-back is the standard answer to it.	Poorly-conditioned teams (heavier rosters, older Liftmen) are noticeably slower into this and it shows on the scoreboard.
Shadow Lift	A defensive Liftman engages a platform alongside the attacking Liftman during a Crown attempt, riding up to contest the goal in the air rather than concede it.	Legal, but the closest thing in the sport to inviting a Crown-crowding call — a defender who mistimes a Shadow Lift is usually the one penalized.

Span-checking — using a platform’s own steam vent against an opposing Spanner — is sometimes described by commentators as “an illegal Shadow Lift,” which is close enough to the truth to be useful shorthand and annoying enough to guild lawyers that the League Board has asked broadcasters twice to stop putting it that way.

Match Day Procedure

Officiating and Fouls

Each match is run by the Whistle (head referee, floor-level authority on all disputes), two Line Judges — one watching Ground, one watching Span and Crown — and the Platform Inspector, whose authority is limited to the platforms but is, in practice, treated as absolute.

Foul	Description	Penalty
Over-pressure lifting	Running a platform above its licensed burn rating.	One-man penalty; platform re-inspected before it plays again.
Overhand core-throw	Throwing the core overhand rather than rolling, tossing low, or lift-assisting it.	Turnover; repeat offense in the same half adds a one-man penalty.
Span-checking	Using a platform’s steam vent to push an opposing Spanner off balance. Dangerous enough that the league treats it as the sport’s most serious foul short of over-pressure.	Automatic one-man penalty.
Core-holding	Holding the core longer than five seconds without advancing it — the sport’s stalling rule.	Turnover.
Crown-crowding	Two Liftmen contesting the same Crown attempt with physical contact at height.	Turnover; official’s discretion on a one-man penalty if either player is put at risk.

A one-man penalty means the offending team plays short-handed — one fewer player on the pitch — for a set interval, decided by the Whistle. It is the sport’s version of a sin bin, and a team that takes two in the same half is usually watching the other side’s Liftmen work uncontested.
