I think I'm missing something with the Hordes. I've seen the AI regularly vassilize Hordes, but I don't see that as a peace option in my Hansa game. I also just saw Ming acquire a bunch of territory from Qirat Horde without colonizing. I believe I've also seen annexation of Hordes by non-Hordes, though I'm not sure about this one. Certainly I don't see this as a peace option either. Can anyone enlighten me as to what's going on? Couldn't find anything on Wiki... or perhaps I'm not going to the right page.
