The Aasa'tha Cluster is an open cluster of stars lying within the rimward edge of Course Sector.

Description / Specifications[edit]

The Cluster lies across As'Kaa and Aasa'tha Subsectors in Course Sector. It is named for the Aasa'tha system and lies some 8 parsecs from the Distant Fringe proper at its closest point. It is considered to contain 10 systems. It lies within the Moat Rifts and is generally considered to mark the border between that rift and the Great Void.

Interstellar Relations[edit]

Although there are no official records of the Cluster having been visited by starfaring Sophonts, the Sath Alliance has almost certainly sent manned vessels. It has declared the cluster to be a protected territory of of the Alliance.


No capital has been nominated.

History & Background / Dossier[edit]

The Sath have long laid claim over all of the barren star systems lying to rimward-trailing of the Distant Fringe proper and the Aasa'tha Cluster is no exception to this.

The normal convention within the Distant Fringe is to name a Subsector or an Astrographic feature for the brightest star within it, a custom that the Sath also generally follow. However, the Aasa'tha Cluster does not fall into this pattern, instead being named for a small, dim, unremarkable star at its center. There is no immediately obvious reason for this, but it has been proposed that Aasa'tha may be the homeworld of a currently unknown sophont species.
