Yes
I didn't want to commit too much on that at the time as I wasn't sure what I wanted the post war Galaxy to look like. Things like the internal cracks, the Babylon project, the Trigati, Clark etc. How close I want to keep to canon and what gets changed.
Early parts of the next fic will establish the situation, broadly this is an armistice but not exactly peace. Earth and Minbar are both still heavily armed and although Branmer does want peace his position is weak and he has a lot of rivals for his job.
The Narn are aggressive, Centauri short tempered, Minbari unstable and Earth mass producing warships. Almost like someone is trying to set up a whole bunch of wars from the shadows... which I guess is no surprise to anyone who has seen the show
There will be some big changes from the start. Nobody knows the Valen thing so Sinclair's path is different, the Babylon project happens because there is still a desire to avoid war but given there is a lot more political instability it is already considered a failure before it even starts. A lot of the Narn/Centauri stuff initially will stay the same but there is the Dilgar wild card to consider which can tip things.
But it will be the EA and Minbar which sees major changes and both will follow a very different route.
