hm perhaps, not something huge but maybe a transcript of a book that you can find in skyrim that details the events immediately after the oblivion crisis (with a few historical inaccuracies of course).
i think that'd be a nice touch and would be a nod towards the oblivion anniversary
Great idea! Even more than that, how about two books: one from the perspective of the separatists and one from the perspective of the loyalists! Both could put a spin on things to make their side seem like the correct one. Heck, the authors of each might even think they are correct, with the true history being reflected better in some ways in either book, depending on the subject. A black and white civil war where one side is clearly in the right would be less interesting than a lore filled plot in which the war is really a great tragedy, with both sides having sympathetic lore and different propaganda and history books.
Edit:
With the second part of the Infernal City story still months away I guess that would spoil the books though.
