Sector

A Sector is a astrophysical co-ordinate system applied to the galaxy.

• A sector is part of a Domain within the Imperium, and contains subsectors.

Description

Mapping unit in astrography equal to sixteen subsectors. Average density 500 to 650 worlds per sector.

Sectors are named, and several synonyms are in common use, including:

• march (or marches),
• region,
• reach (or reaches),
• quadrant, and
• matrix.

e.g. The Spinward Marches, for example, is a sector.

Charted Space Overview

As a rough means of comparing size, the sector counts of the large interstellar states and areas of settlement are:

Sectors of the Major Races in Charted Space

Polity (Government)	Society (People)	Sectors
Third Imperium	Imperial & Vilani	19
Aslan Hierate	Aslan	15
Hive Federation	Hiver	11
Two Thousand Worlds	K'kree	09
Vargr Extents	Vargr	09
Zhodani Consulate	Zhodani Humaniti	08
Solomani Confederation	Solomani Humaniti	05
Droyne Oytrip Yatroy	Droyne	Unknown

Notes:

• Several sectors are known by other names (by non-imperial races). Strangely enough they use the same co-ordinate system.
• The earliest known use of the term sector was among the Vilani, who used a slightly smaller 'parsec', compared to the current, Solomani-derived parsec.
• The library refers to all sectors with the word Sector, thus Riftspan Reaches, or Dark Nebula are known as Riftspan Reaches Sector or Dark Nebula Sector in Library Entries even though the former name is used in normal discussion.

Please see Sector Map and Sectors for an alphabetical listing of all sectors, and alien toponyms (names) for those sectors.

Charted Space Table

The following table lists the Sectors near the Imperium; see articles on the other empires for sectors in their Domains, and Subsector Map for a map of allegiances by subsector.
