Reavers' Deep and Daibei during The Long Night
I like that as an aspirational goal. There ought to be some algorithmic method of "rolling back" UWPs across a period of time, but it's likely to be a rather complex one.
Oh, you are
not Kidding! I did the rollback on two sectors by hand (a little bit of automation, but not nearly enough!) when I made the setting for my SBRD campaign (see below) based on data from TravellerMap.
I don't know if you're aware of this, but TravellerMap already has a rudimentary version of this concept: you can view the maps in several different milieux. Currently, the only milieux before 1105 are the Interstellar Wars, the T4 Milieu 0 and 990 (the Solomani Rim War), but it's a step towards what you're suggesting.
I rolled Reavers' Deep and Daibei sectors back to 3731 AD, a little over halfway through The Long Night, for my SBRD campaign back in 2013-14. I used data from TravellerMap as my starting points, and then used TravellerMap to make my sector and subsector maps (with a lot of help from inexorabletash!), but it was unofficial (definitely non-canon!
) and I don't think my revisions were stored in any way that I could share (if I ever did know how, I've unfortunately forgotten; I'm not sure I even have copy still of the Access DB I used to make my rollbacks). If anyone is interested in that rollback (I hate to see all that work go to waste!), the best way to view it is probably to go to the maps in the
SBRD Campaign sub-wiki in Traveller Wiki (thanks again, tjoneslo!); everything is thoroughly clickable, so you can click subsectors on the sector maps to go to the subsector pages, then click individual systems to go to system pages. Here is the
Border Map, covering the main campaign area, 12 subsectors along the border between Reavers' Deep and Daibei. Here are the
Reavers' Deep and
Daibei sector pages; there aren't full-size sector maps, but the mini-maps link to all subsectors.
