Spinward Main

The Spinward Main is an astrographic group of systems in the Spinward Marches Sector, each within jump-1 of another.

• Together, this grouping forms a corridor of jump points that allows simple jump-1 ships to travel to fifteen of the sixteen subsectors within the Spinward Marches, and to 236 of the sector's 439 known worlds.

The Spinward Main

Meandering throughout the Spinward Marches is an informal trade route called the Spinward Main. This Main is a line (actually several lines, with branches) of worlds each only jump-1 from the next. The result is that long, often profitable trading journeys are possible even for lowly jump-1 ships. From Regina, the Main extends coreward, into the subsector. It also extends spinward, beyond the Imperial borders, ultimately to Querion Subsector and the Zhodani Consulate.

History & Background (Dossier)

The Spinward Main has been popularly divided into several subsections, such as the Regina Cluster, a cul-de-sac branch which enters Regina subsector at Jenghe and extends as far as Efate.

Named segments include:

• Bowman Arm
• Collace Arm
• Darrian Cluster
• Entropic Worlds
• Glisten Arm
• Gram Arm
• Metal Worlds
• Mora Arm
• Regina Cluster
• Sisters' Reach

Subsectors

By long-standing tradition, heading in the direction of District 268 (broadly Spinward-Rimward) or along the Mora Arm (Trailing-Rimward) from Regina Subsector is ‘Down the Main’; the opposite direction is ‘Up.’

Worlds & Sectors (Astrography)

While most of the Main lies within the borders of the Imperium, branches enter the Darrian Confederation and the Sword Worlds Confederation, and some segments traverse neutral space.

• Short branches of the Main extend into both Foreven Sector (17 systems) and Deneb Sector (6 systems).

This astrographic feature is found in the following areas:
Charted Space – Third Imperium – Balkanized Space:

• Deneb Sector
• Foreven Sector
• Spinward Marches Sector
