In partial apology for the lack of artwork thus far, I bring you a map of the Associated Worlds, constellation by constellation!
(Click through for the full version. Caution: it’s a big image, 3049 x 3030.)
Key-wise, gold constellations represent the Imperial Core and Fringe, blue the mainstream Associated Worlds, purple the Expansion Regions, and green the Periphery. Red constellations represent the off-the-edge-of-the-map places, namely the Leviathan Consciousness and the connected constellations of the Voniensa Republic. Thin lines are interconstellation stargate connections; thick lines are special high-capacity arterials.
The major connected sets of those are the Worlds’ major trade routes: in green, the Lethíäza Trade Spine; in red, the Mercantile Corridor; and a rough circle in black at the edge of the major Worlds, except where it shares a link with the Spine between “58” and the Azure Fade, the Circumferential, or Golden Band.
I’ve annotated the approximate locations of the major powers, and also (in small text) of a few minor powers that have been mentioned and about which there might be curiosity.
(Oh, and when it comes to those constellations currently numbered – the aforementioned “58”, “E76”, and “P13”, et. al.? Apart from a couple of potential spoilers, that’s my innovation space/creative breathing room. Pay no attention to the Doylist explanation behind the curtain.)
