Segmentum
The Imperium is divided into five fleet zones known as the Segmentae Majoris. Although intended for purposes of fleet administration and shipping controls, the Segmentae have evolved into administrative divisions of the Adeptus Terra.
All shipping is supervised within the jurisdiction of one of the five Segmentae. Each Segmentum has an orbital headquarters called a Segmentum Fortress or Segmentum Naval Base which forms the base of fleet operations within the Segmentum. The Segmentum Fortress is controlled directly by a high-ranking official of the Administratum known as the Master of the Segmentum.
Segmentum is a designation used by the Imperium; other races have no need for it, being far less widespread, or confined to closely packed star systems.
The Segmentae Majoris and their bases are:
| Segmentum | Zone | Base |
| Segmentum Solar | Centre | Mars |
| Segmentum Obscurus | North | Cypra Mundi |
| Segmentum Pacificus | West | Hydraphur |
| Ultima Segmentum | East | Kar Duniash |
| Segmentum Tempestus | South | Bakka |
Segmentum comes from the word segment, to cut into pieces. The galaxy is such a vast place that it would be unmanageable without this system.
Segmentum is also used in conjunction with another word to indicate the primary structure of that segment, such as the Segmentum Naval Base.
