The Sydymic Outworlds Cluster

From publisher blurb: The Sydymic Outworlds are at the very edge of Imperial space. Most trade is internal, but a considerable amount of cross-border dealing goes on (originally mainly at Ked, now moving elsewhere) between Imperial firms and their counterparts in the Khuur League and beyond. The cluster is also important as a link on the Jump-4 route into Gateway sector and thus sees official Imperial vessels passing through its ports and some long-range ships from Gateway Sector going the other way (mainly from the Galian Federation).
