I think a resonably strong case can be made that what's marked on Traveller Map as the 'Regency of Murimi' is in fact part of the Heirate and Aslan dominated rather than Human dominated.
It certainly makes more sense than the alternative.
For one thing ... how would the Solomani settlers have gotten there? What was the route?
First of all, we know for a fact that they couldn't have used the
J-5 Trans Hierate Trade Route crossing the
Great Rift in the
Riftspan Reaches sector, since that was Aslan controlled and the Aslan wouldn't have tolerated Solomani colony convoys crossing their space to go "further spinward" and lay claim to territories that the Aslan themselves would someday want to expand into. I mean, why do a competing species a "solid favor" when that simply means that they will ultimately wind up being a competing power in control of territory the Aslan will eventually be wanting (meaning: needing!) to expand into? It doesn't make near term nor long term sense.
Furthermore, the Regency of Muirimi was supposedly settled during the
Long Night (-1776 to 0), while the
J-5 Trans Hierate Trade Route crossing the
Great Rift in the
Riftspan Reaches sector wasn't even discovered until -1044 and would have been jealously (and zealously) guarded by the
Wahtoi clan during the
Long Night when the region would have needed to have been settled by the Solomani. So easy answer ... the J-6
Verge Connector would not/could not have been used for the Solomani to deploy sufficient colonization resources driving towards
Iphigenaia sector during the
Aslan Border Wars (-1118 to 360) time period of the
Long Night (-1776 to 0).
So with access across the
Great Rift blocked by the
Aslan Border Wars which started before the J-5 route across the Riftspan Reaches was even discovered ... the only colonization path open for Humaniti to settle in the region would have been a continued outward expansion of colonization like so:
Solomani Rim sector
Diaspora sector
Massilia sector
Core sector
Vland sector
Corridor sector
Deneb sector
Spinward Marches sector (
Gram of the Sword Worlds fully settled by -200, but Solomani traders encountered
Darrian in -1151)
The Beyond sector
Vanguard Reaches sector
Iphigenaia sector
In other words ... an almost absurdly LONG HAUL for Solomani colonists to get out that far (from Terra), of approximately 11 sectors.
Now, given than there are Solomani pocket empires even further out in the Mavuzog and Theta Borealis sectors, it's not impossible for Solomani settlers to have "set up shop" in what later became the Regency of Muirimi ... but it still somewhat strains credulity that there would have been sufficient colonists THAT DESPERATE to go THAT FAR OUT just to find a "quiet spot" to settle down and colonize somewhere. I mean, the intervening sectors would have had
plenty of underdeveloped places those colonists could have laid claim to and begun building themselves up in.
My point being that the only reason for Solomani colonists to go as far as
Iphigenaia sector, Theta Borealis sector and/or Mavuzog sector would have been to GET AWAY FROM the
Long Night and cut all ties with the former
Terran Imperium in a bid for stability and survival by being SO FAR OUT that meaningful trade and diplomatic relations would be impossible at such distances. In other words ... A Fresh Start™ for Humaniti would have needed to be the ideal for such colonists.
Not impossible ... just really really implausible, all things considered (logistically speaking).
And one of those considerations would have to be ... what technology level (and therefore jump drives) would have been available to such a colony fleet? I can easily imagine a colony fleet being limited to TL=9 (during the
Long Night), meaning Jump-1 and needing to use extra fuel fraction and tanker relays to be able to cross 2-3 parsecs without a source of wilderness refueling (LBB2 "standard" hull designs would be horribly cramped for this at TL=9, and without fuel purification plants would doomed to unacceptably high misjump attrition losses, so they would have to be LBB5.80 colony ship designs).
Cattle Car Galactica indeed ...
Of course, compared to the
Distant Fringe ... this is practically a walk in the park ...

54-55 sectors rimward+trailing is a REALLY LONG HAUL ...
