Near Space

Drift travel technology divides the galaxy into two sectors: Near Space and the Vast. Near Space contains the Pact Worlds system and most of the worlds colonized and contacted so far by their explorers, but there are still thousands of Near Space worlds yet to be investigated. Near Space worlds tend to be closer to the galactic center, and incidentally to the Pact Worlds, but the real determination is the density of Drift Beacons  in the general region of space near a world. Thus it's possible to find pockets of Near Space worlds all the way out the the galactic rim.
