When did the Concordat, Outworlds and Magistracy stop using internal provinces? It's been confirmed that in the Star League era the Concordat had 4, the Magistracy 3, and the Outworlds... well, more than I can remember at the moment (6? 7?) but they're not depicted consistently in the Star League era books, which was confirmed to be an errata in one case, and they aren't depicted at all in First or Second Succession War. The decline in the size of each of the three realms seems to have started relatively slowly, but I'm not sure if all three showing no internal provinces in either Succession Wars volume is an oversight or a conscious decision to do away with provinces and provincial capitals and just run everything from their capital worlds.
