Sector
Sector (Astrography) Synopsis
A Sector is a astrophysical co-ordinate system applied to the galaxy. A sector is part of a Domain within the Imperium, and contains sub-sectors.
Sector (Astrography) 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.
Sector (Astrography) Charted Space Overview
As a rough means of comparing size, the sector counts of the large interstellar states and areas of settlement are:
Polity | Society (People) | Sectors |
---|---|---|
Third Imperium | Imperial & Vilani | 19 |
Aslan Hierate | Aslan | 15 |
Droyne Oytrip Yatroy | Droyne | Unknown |
Hive Federation | Hiver | 11 |
Two Thousand Worlds | K'kree | 09 |
Solomani Confederation | Solomani Humaniti | 05 |
Vargr Extents | Vargr | 09 |
Zhodani Consulate | Zhodani Humaniti | 08 |
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 names for those sectors.
Sector (Astrography) 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.
The following key helps to explain the Charted Space Table:
- Red (Pink) Sectors are Mostly Imperial-Controlled
- Yellow Aslan
- Green Vargr
- Purple Hiver
- Orange Solomani
- Blue Zhodani
