History of the Rimworlds


Imperial History of the RimWorldsLibrary Data

Imperial expansion into the Rimworlds has been, from the very first, sporadic and under resourced. Consequently, the Sector Dukes were forced to rely heavily upon their Subsector Dukes and the planetary and subsector navies at their command.

Such Imperial Naval units as were assigned to the Rimworlds Sector from time to time were very much used as a mobile reserve to shore up the various fortress worlds that were used to dominate volumes of space.

Berimarís Sceptre, Gazolan and Thurgandarn were the most stable of the Rimworlds subsectors and, apart from the confusion of the Seventh Century Civil War and the Sarkul Wars of the Ninth Century, enjoyed an extended period of peace. Kaorin Subsector, after the loss of Riinu Subsector to the Klarthur Confederacy in the late Seventh Century, has also developed a thriving economic and industrial base.

Daltharmai, Gamelea, Nolgor, Miazan and Gazul Subsectors have always been under resourced and have faced increasingly well organised and technologically adept alliances of non-Imperial states.
