Quite a bit of effort seems to have gone into this map, and it looks good!
At the same time, noticed there are a number of locations included on the Madalfred maps that are not located on this map.
I tried my best to stick to melding official with unofficial. So, I used Sigmar's Heirs as my base and all of 2nd ed WFRP to build on it and added some stuff from outside sources. I LOVE Madalfred's stuff, but I wanted to try a semi-official version that suited what I wanted.
That being said, I wish someone had a Gotrek and Felix Gazetteer of some sort that lists all of the locations they went too. I'm sure those books have a lot of great places.
Again, it's a kind of mish-mash of Official and unofficial with being as close to "official" as I feel is neccessary.
That's an excellent map, Ernst! Though I think it disagrees too much with the geography of 1st edition WFRP for me to find it useful, sadly. Empire maps are just too different from each other for it to be possible to make one map to suit everyone!
Bergsburg: Now I know some fine folks made an unofficial WHFRP adventure but I don't think the town was recognized in any official capacity. I mean I may be wrong but Hergig is used as the provincial capital in The Enemy Within.
Actually, The Enemy Within specifically says that the capital of Hochland is Bergsburg! And yes, it appears on some of the maps. It's certainly official.
Bergsburg also appears on the map in Warhammer City (the Middenheim book that had at least three different titles). Again, it's described as the provincial capital of Hochland.
As you say, it is utterly impossible to make a map of the Empire that will suit everyone. This one works well for our group and as a GM, the toggling of certain layers really helps us. The Trade layer gives me an idea on the fly of the wealth level of a town and where they trade, the political layer lets me know who rules over an area my players go to. This way, I can also toggle off layers I don't want my players to see if I show them a portion of the map.
