This is the subsector as presented in GT:Behind the Claw. This applies to the GURPS Traveller alternate history, but can work for late MegaTraveller period too, assuming the Daryens progressed similarly in the OTU and the GTU. Given that, it can work in the OTU from 1120 up until just before The New Era. While this is completely consistent with the GURPS Traveller timeline (with two minor exceptions*), it is still presented in the classic UWP format.
The Darrian Confederation gained significantly from the Fifth Frontier war. Its main adversary, the Sword Worlds was decimated and ended up splitting into two separate polities (the Sword Worlds and the Border Worlds). In addition to relieving the political pressures, the Darrian Confederation also regained undisputed control over the previously contested Entropic worlds.
Because of this new freedom, the Darrian Confederation
has become more expansionistic, sometimes testing the otherwise excellent
relationship with the Imperium. This expansionism lead the Confederation
to increase the pressure on Nonym to rejoin the Confederation, which they
eventually did after a show of force with a Special Arm fleet. Condaria's
population voted to join the Confederation in 1114. (See below *
There are reports that the Darrian Confederation is working covertly on Uniqua to "liberate" it from Garoo, but there is no proof. The Confederation attributes the reports to "typical Garooan paranoia".
Once the Fifth Frontier War was over, and the Sword World threat was effectively removed, the Imperium returned the naval base on Nosea back to the Confederation.
The majority of the population of Roget are the decendants of mercenary Aslan who, while fully part of the Darrian Confederation, wish to maintain their cultural identity. The Aslan scattered elsewhere (Zamine, Engrange, Ektron, Cunnonic and Daryen) have mostly assimilated into Daryen culture. This assimilation is to the point that native Aslan would consider them full "barbarians" and refuse to deal with them. Interestingly, even though the Roget Aslan have gone to great lengths to maintain their culture, they have no problem dealing with any other Darrian Aslan, and are considered "other Aslan" by native Aslan as a result.
Mire, content with being the political epicenter of the Darrian Confederation, let their technological infrastructure lag the other primary shipbuilding planets. Recently, they have started to correct that, and, as a result, will likely be recognized with their first technology level increase in almost a thousand years within the next decade.
Entrope is still trying to recover from the devistation wrought by the Sword Worlds. The popular dictator, a war hero who lead the coup that brought Entrope back to the Darrian Confederation, is finishing the task of cleaning out Sword World sympathizers and beginning the long difficult task of reconstructing their economy and starport. The recent reclassification of the starport is evidence that their hard work is slowly (some would say too slowly) paying off.
Dorannia is listed as being a part of the Confederation, but there is no other support for this in BtC, including in the Darrian Confederation description, the subsector description or even the planet's description. Therefore, on this map, it is listed as unaligned.
Zbume was listed in CT, MT and even TNE as having a population of hundreds (pop 2). For some inexplicable reason, BtC lists them as having a population of "under a hundred" (pop 1). I have chosen to ignore this, and have left Zbume with a population level of 2.
