I'm definitely very grateful that one likes my writing style more than inspired by Planet of Hats' al-Andalus TL. I'm trying my best to adapt the style of writing from the articles and books I read, so I'm glad that I was able to deliver on that front.
We're definitely drawing towards an end of Chapter 1 where I'll definitely post the first map of Europe and its immediate surroundings as some sort of nice conclusion of it. But for now, I would just refer to this map since nothing major has changed during this decade outside of Polabia and Lotharingia, but both will get their own minimaps for their respective updates once the time comes. I'm also a big fan of maps, so I'm actually quite excited to be able to do the big one soon-ish, considering it will probably serve as the foundation on which the next chapters will build upon.
you're doing smashing on the writing. As you know from my own timeline, I also favor an academic approach to the writing - but it can be a deceptively difficult style to write in. You're doing really well, and you've inspired me in a few of the things I want to depict in my timeline as well (though, naturally, there's a few hundred years of difference between your setting and mine, and so our kingdoms are in pretty different positions).
