That's an element I feel is handled a lot more interestingly in the Star Fleet Universe than in the Franchise, personally.
I wonder if there could ever be actual novels set in the SFU? Would there be any licensing or legal issues that would prevent that?
There's already been a trial run of a Klingon-themed short story anthology, For The Glory of the Empire, and there should be a Romulan-themed one about the Day of the Eagle sooner or later.
Full-length novels shouldn't be an issue if ADB do the print run themselves, but I wouldn't hold your breath when it comes to anything being released via Pocket...
It would be cool to see....
How the Romulan Republic came about
There's a non-historical take on the start of that event in Stellar Shadow Journal #1 - but I can't think of an historical fiction piece which tackles it, off the top of my head.
