Migrating the Dark Nebula to the Galaxiad

I am thinking about migrating my Dark Nebula variant-OTU setting to the Galaxiad milieu of the Official Traveller Universe. This would be a refreshing change, as well as a good setting with a wide-open future. Playing in the Far Far Future of the Galaxiad is liberating - I get a narrative license utilize any part of the vast OTU Canon while ignoring other parts. For example, I can easily tell players that the Dark Nebula boardgame map is the actual map and that the Dark Nebula subsector maps from Travellermap are inaccurate Antediluvian maps! (I can do this in any milieu, of course, but it's extra easy in the Galaxiad).

It is 1901 Old Imperial, known locally as 411 Postdiluvial. (PD 411).

You see, the local collective term for the various catastrophes surrounding "The Collapse" is the Deluge

The Deluge started on 1116 Old Imperial and ended with the passing of the Wave through Aslan space in 1489 Old Imperial.

So, three historical eras in Dark Nebula historiography and public discourse:

  • Antediluvian Era, up to 1115 Old Imperial
  • Deluge, 1116-1489 Old Imperial (Diluvial Years 1-273)
  • Postdiluvian Era, 1489 Old Imperial and on (Postdiluvian Year 1 and on).

Solomani refugees came in the late Diluvial years, once the Wave passed the Dark Nebula and was still crossing Aslan space. They settled on abandoned, dead, or mostly-depopulated Aslan worlds. This gives us several human worlds in the region, who are now in conflict with the resurgent Aslan.

Max local TL in the Dark Nebula region is TL11. Anything higher is either an Antediluvian artifact or a rare import.
