The Marches
The Empire is organized into five provinces, called "Marches." The central march, Gross Crobuzona, represents the earliest settlements Crobuzon established during the colonization race against the Witchocracy. The other four marchs are both administrative districts as well as machines for expansion- the industrialised worlds closest to Crobuzon finance expansion out to the border worlds, who send raw materials back to the vast refineries and manufactories of the core. The politics involved are byzantine and highly competitive- it should be noted that 20% of the votes in Parliament come from Bas-Lag itself, and that a further 30% are concentrated in the Gross Crobuzona march. The four border marches all have the votes heavily concentrated amongst the industrialised worlds, essentially placing power in the Marches in the hands of the industrialised planets. However, the creation of new Parliamentary seats is more or less controlled by New Crobuzon, which gives each march a reason to attempt to develop it's border systems, so as to recieve more clout for the march as a whole against the other marches in the Parliament.

Gross Crobuzona
1. Bas-Lag
The capital world of the Empire. A full tenth of the planet's surface is covered by the vast expanse of the City of New Crobuzon, capital and heart of the Empire. At the center of New Crobuzon, where the Tar and Canker rivers meet to form the Gross Tar which then flows out to Ironbottom Bay, lies Perdido Street Station: hub for the city's ancient railways, a vast edifice which contains the center of Crobuzon's government,
2. Steelshatter
This system lacks any inhabitable planets, but supports a huge population in the airship-cities and vast orbitals in the system's five gas giants. Home of the largest warship yard in the Empire.
- 3 industrialised systems, three lightly inhabited systems
Kergudter March
3. Tarsis Deux
This major fleet base is in the most heavily populated system in the Empire outside of Gross Crobuzona, and is home to the March capital.
4. Celebrantus
This industrialised system is home to a vast rockmilk extraction enterprise, which provides a significant portion of the Navy's thaumaturgic fuel. Recent Socialist and Unionist riots amongst the miners have forced the Militia to increase it's presence.
5. Ikt Sin Vanapur
A border world notable for it's extensive Ghosthead ruins and a large colony of expatriate vampir who settled there after fleeing a Teshite purge. Also, supply base for most Corewards expansion and exploration.
-3 industrialised systems, 9 minor worlds.
Sud Tempost March
6. Canopus Minima
This system is the capital of the Sud Tempost March and a major hub of trade. It's twin, Canopus Maxima, is sight of a major Militia base where many troop transports are kept between deployments.
7. Fort Desdemonia
Established since the end of the Frigid War, this major fleet base is turning the minor border world it resides on into a bustling center and a source of new Crouzoner expansions antispinward.
8. Crais
This system's watery planet is home to a large Cray population, additionally, it is the corporate headquarters of Skillia & Johansen, Crobuzon's largest difference engine corporation.
9. Genjarii Station
Former den for Teshite-financed privateers, taken by the Navy during the Frigid War, now a major naval research base with proving yards for new ship designs.
-5 industrialised systems, 17 minor systems
Sparse March (Former Teshite)
10. Restitia
This system was once the home of the Witchocracy's feared Venomfleet. The fall of the Witchocracy lead to most of the battlewagons being scuttled, instantly destroying the system's source of livelyhood. Teeming masses of poor make thier home in the abandoned slips and shipyards, and a great city has been built out of the hulks in high orbit. This city, Jostle, is known for lawlessness. However, it is becoming increasingly profitable as it is through Jostle that the wealth collected by the Rimwards Expansion flows to Bas-Lag. Known as a hotbed of Socialist sentiment.
11. Albiachor
This industrialised Teshite world's native inhabitants found themselves becoming masters when the Witchocracy fell and Crobuzon established tham as the system's new ruling class. Now, the men of Tesh labor in factories while Albiachorans dine on the finest china. Site of the march's main fleet base and capital.
12. Imrha's Reach
This rough-and-tumble border system holds the Salácus Street Northwest Company's field headquarters (as opposed to their main offices at Salácus Street in New Crobuzon.) The presence of such a major accredited company's offices and associated facilities has lead to an economic boom as aetherclippers come and go from the wild.
-2 industrialised systems, 18 minor worlds.
Spiralsworn March (Former Teshite)
13. Ostmarch
This major industrialised system was uninhabited when the Teshites arrived. It's populace sided with Corbuzon against the rest of Tesh when the Witchocracy crumbled, and was rewarded well. This system's asteroid belt is home to a large fleet base as well as extensive military facilities and a shipyard which produces destroyers and other escorts.
14. New Arzamas
New Arzamas's inhabitants, primitive humans who had only recently discovered thaumaturgy, were invaded by Tesh. Crobuzon supported the Arzamasi, and the ensuing meat grinder broke the back of the Witchocracy without the loss of a single Crobuzoner Militiaman. New Arzamas is now the March capital; however, most positions of power belong to Crobuzoners rather than natives.
4 industrialised systems, 9 minor worlds
