Here's a couple of maps produced by a group of players who were on contract or worked in concert with Agents of Gaming. These particular maps weren't actually published:
Systems and Territories - 2260 Systems and Territories - 2263 Note that the "official" map for 2257, which was published in the B5Wars rules compendium is slightly different from the 3063 map.
The Narn Regime also includes: Carridun, Quadrant 7, Sorith, Tachung, Maroth, T'll'in, Quadrant 37 and Ardun
There are a few other changes as well:
Balosians don't have Alaca
Lumati don't have Trembas or Selchat
Centauri don't have Ildra
Tiree, Troth and Markab belong to the Markab, not the EA
Ch'lonas lack Zacalth
Deneth lack Quartha and Korel
Cascor lack Krish
And the Drazi, Centauri, and Brakiri lack those worlds which the Narn controlled (aforementioned).
Note that the jump map doesn't correlated to normal space. Some systems in hyperspace might be farther away from eachother than in real space. I'm not sure, but I aren't the Centauri from Alpha Centauri? And if that's the case, the closest system to Earth in real space is damn far in hyperspace. I'm not sure however. . . Obviously the Centauri are self-named, not by the Earth alliance.
If anyone wants more information or maps let me know I have two zips, one of which has these maps + 2 others. And one details the Centauri republic at its height. Though unless TBP is going to do some Orieni ships, I don't think the latter will be of any use to anyone.
