Heh, maybe some of them, but certainly not all the Wends, thanks for spreading my TL though, i do have some great plans (that will be revealed soon) for the Wends.
The development of "Sorbia" is pretty possible actually, by the 8th Century the slavs were starting the development of their own state-like polities, the Sorbs didn't develop their state probably because of the problems of being a frankish vassal, and we have some things pointing to a possible will to migrate into Thuringia, if you destroy frankish presence by the 7th-8th centuries on Germania you're certainly wanking the sorbs lmao. The Obotrites are other possibility though their position isn't really *good* for an, well, *top-notch* state.
