A Main is a grouping of systems, forming a chain of worlds, all reachable by a Jump-1 capable starship.

Description (Specifications)[edit]

This grouping provides a sort of “corridor” allowing jump-1 capable ships to travel to any world along the chain without ever exceeding jump-1.

  • Usually a Main encompasses 50 or more systems.
  • For ease of reference the main may be broken into arms, or branches.
  • Smaller groups of systems, between 5 and 50, all reachable by jump-1 are referred to as a trace or cluster.

History & Background (Dossier)[edit]

Many such groupings of worlds exist in the Charted Space.

Mains & Branches[edit]

Star systems on long (51 or more stars) mains. Frequently are separated into arms or branches for identification purposes.

Prominent examples include:

Traces & Clusters[edit]

Star systems on smaller (5 - 50 stars) groupings. Most of these astrographic features are located in just one or two subsectors.
