Pre-Republic collection of 15 well-developed star systems and 30 smaller outposts. The dominant race in the collective was the Uzed. In RR 130, the Triarchy first encountered the Republic when their respective trading interests met. The Triarchy has spent most of its existence outside of the Republic simply because it is so far out on the Rim.

In relative isolation, the Triarchy developed the biological and eccological know-how to produce starship hulls out of Bio-metallic Alloys.

Following the decline of the Uzed after a severe disease outbreak throughout their state, regular contact with the Republic was lost.

A "Triarchy" is any form of government where the decisions are made only by the "Tri" gender.

The Disc Triarchy takes its name from the Disc Nebula which helps to define its boarders. The nebula, in turn, takes its name from its shape as seen from (bigworldhere).
