I am fielding a middenland force that is based around Carroburg. My understanding, from Heirs of Sigmar (WHFRP), is that Carroburg is home to the Elector Count's heir apparent, Wolfram Todbringer and that the EC of Middenland has a home there. In addition, one of Todbringer's titles is "Prince of Carroburg." This implies that Carroburg is loyal to Middenland.
However, reading about the Carroburg greatswords descriptions in Empire army book, it implies that Carroburg is a Reikland city.
I realize the city is chartered and "free," but would I be able to field a Middenland force with Carroburg greatswords?
Can I even have a middenland force based out of Carroburg if I want it to be led by Wolfram and the Duke Leopold von Bildhofen?
If this is not viable, then I suppose they will be based out of Delberz.
