The Orion OB1 Association (or, more correctly, the Orion Molecular Cloud Complex) is located rimward of the Hive Federation and spinward of the Rim Route. It spans tens of sectors. Almost all of the systems have belts as mainworlds, and almost all contain at least half a dozen belts. The major worlds are located around stars visible from Terra. A considerable fraction of the populated systems are M’norr Republic client states. There also are small, independent pocket empires (e.g. the three-world Dorrim Mining Confederation in Mintaka Sector). There are many routes in the Association. The largest and most frequently-used routes are the Fire Routes. A band of rift density several parsecs wide runs around most of the edge of the Association.
Notably, the name Orion OB1 Association is actually somewhat a misnomer and the region should really be referred to as the Orion Molecular Cloud Complex, of which the Orion OB1 Association proper is just a subpart, but Orion OB1 Association is the name most used for the region by its inhabitants. The term Orion OB1 Association proper refers to the brightest stars within the OMCC; these systems are locally known as “Major Orion Worlds” and typically function as the capitals/administrative centres of their subsectors or sectors.
In the sector tables, “Ori.” is an abbreviation of Orionis, and “G.” is the same in the actual name – for example, sector at 3 Trailing, 9 Rimward (+3/+9) (shown as “47 G. Ori.”) is 47 G. Orionis Sector. The sectors with their names in brackets are within the main rectangle of Charted Space.
