Sorry for the lack of responses, I've been getting nasty migraines at work, and have been passing out upon getting home.
I suppose that could work. I don't have to follow the DBWI exactly I suppose (just honor the spirit of it). One of the events occurring was that apparently Charlemagne's Empire collapsed early on, causing the HRE to never form. My interpretation of this is that the Slavic/German linguistic border is far more west, with Polabians still existing, and Sorbs still being a majority. Since there'd be no political entity unifying anyone, I presume that the German dialects, such as Bavarian, Swabian, Saxon, etc would continue to diverge until you basically had a number of West Germanic languages, so a relatively fragmented Germania (from Rotterdam to Triest).
I question whether France would exist as a solid entity, or if, say, Aquitania would be independent. In the original thread, it was a solid kingdom, but since this would take place ~200 years prior, so there might be more fragmentation?
Outside of Europe, my focus will shift to Africa and the Middle East, where we should be having the Maghreb Sultanate, the Egyptian Malikate, the *id Caliphate (not sure what family), the * Khanate (not sure of the name yet), Persia, some setup in India (thinking fragmented with the potential to unify), a divided China (at least north and south kingdoms, possibly more fragmented than that), and Japan (more unified than OTL at this time, still possibly partially fragmented).
I imagine that the Americas are a hodgepodge of colonies of these powers as well as native powers. Not sure about non-North Africa yet.
