After having fun fleshing out the Venuraski Sector Dukes, I realised that to round off this section of the History of the RimWorlds I really needed a brief account of the conflict in Gazolan Subsector that claimed the lives of both Kolin I and his son Metch. And to write about this conflict, I needed to map the subsector.
This would be the first subsector I have mapped for my campaign in something like 15 years. As I began setting up for it, I decided that I would sketch out the basics in Heaven and Earth, and then edit and move systems as required for the narrative. While the actual system generation rules would be from Classic Traveller, I wanted to take the opportunity to look at the Mongoose Traveller world generation rules to see whether they added anything to the mix.
As I have been going through my six extant subsectors, I have found it very helpful to look at the starmap in Quadrant form (more properly sextant form, I guess). At this higher-level viewpoint, constellations of stars form and logical local polities and cultural/language areas become obvious. So, having run the generator, I picked out the Jump-1 groups and marked up the current Imperial frontier.
With seven groups, I had a couple of good candidates for the location of a wealthy pocket empire or confederation, that might give Kolin I grief when he came calling in the middle of the sixth century. Though, looking at the current starports, either the subsector had really fallen on hard times, or I was going to have to do some serious editing work.
