Corridor is the vital sector
linking the Spinward Marches with
the Imperial center.
The only viable trade
and communications routes between the two regions must pass through a
relatively narrow channel of star systems
wedged between two
great starless rifts.
Unfortunately for the Imperium, the territory is shared with several
small belligerent territories; the Imperial Corridor Fleet has a
patrolling the sector starlanes, maintaining a semblance of peace, and
Imperial worlds and borders.
The sector contains 267 systems dramatically split by the Great Rift; 69 systems lie rimward of the Rift and
149 systems form
the coreward third of
Corridor is named for its role connecting old, well-established
Sector with the frontier sectors Deneb and the
Marches. The name Corridor dates from about 140 and has displaced
old Vilani name (Eneri, rough
"star salad") for the sector.
