Driving this interstellar trade are two Agricultural (Ag) worlds, five Non-Agricultural (Na) worlds, one Pre-Agricultural (Pa) world, three Pre-Industrial (Pi) worlds, one Rich (Ri) world, and two Industrial (In) worlds. The governments in Diadem maintain two Exploration bases, two Naval bases, one Military base, and one Clan base. The highest technology level is 13 at Nashua (Vanguard Reaches 1415).

Diadem, subsector F of Vanguard Reaches, contains 24 stars; 10 monostellar systems, 7 binary systems, no trinary systems, and no systems with four or more stars. 14 of the 17 systems have native gas giants. There are no Asteroid (As) belts, no Desert (De) worlds, two Garden (Ga) worlds, one Ice-capped (Ic) world, one Poor (Po) world, four Vacuum (Va) worlds, and one Water (Wa) or Ocean (Oc) world.

Diadem has an estimated population of 5.8 billion distributed across three High population (Hi) worlds, five Moderate population (Ph) worlds, four Non-industrial (Ni) worlds, three Low population (Lo) worlds, and no Barren (Ba) worlds. The highest population worlds are Traxler (Vanguard Reaches 114), Castrum (Vanguard Reaches 1215), and Tiffanye (Vanguard Reaches 1619). The population consists primarily of 3 sophont groups.

History & Background (Dossier)

Diadem Subsector was a remote backwater even by Vanguard Reach's low standards. Aside from trade with the Murians, there was little in this subsector to excite or attract. While a number of industrial worlds did emerge, they were considered to be unfortunate accidents rather than deliberate development. All of this changed with the arrival of Aslan Ihatei in the neighboring Old Colonies subsector, just years before the Imperial Civil War. A brief economic boom resulted from trade with the new colonies, creating an improvement in local conditions. And when the war broke out, the locals profited handsomely from the influx of Corellian League military and privateers sent here to prevent further ihatei advances. The Gold Road was wealth du jour, after the Collapse, bringing a steady stream of foreign merchants through the subsector. It also brought an influx in organized crime, a quiet power struggle between the Corellians and feuding Aslan clans, and no small amount of petty intrigue.
