Okey I love this mod, Can't wait!!! Dunno if this info is usefull, but conserning Norway and the campiagn map I have some suggestions :P

----------- YOUR IDEA
NORWAY AREA
* Hordaland - Bergen (town) (rebels)
* Hafrsfjord (rebels) - Nord-Jaeren / Stafangr
* Vaestfold - Kaupang (position close to Oslo but further down the fiord)
* Trondelag - Trondheim (town)
* Hologaland (modern Lofots area and mainland next to it) - Narvik
* Northern Norway - Tromso
* Finnmark - Kirkenes (situated next to Barents Sea and modern Russian border)

----------- MY Research :S??
* Hordaland - Bergen (Indeed the most important city in the medieval period)
* Hafrsfjord - Stafangr (Modern Stavanger yes..)
* Vaestfold - Kaupang\Oslo
(Good idea, Oslo was a small "settlement" at 1000-1100, and later became the greatest city. I would rathered used Oslo, you can also use Tunsberg as this was the first city in Norway, or both)
* Trondelag - NIDAROS!!!! (Important city, don't drop it! It was the capital for a long time. It's name was Nidaros NOT Trondheim :)
* Hologaland - Vågan!! Not Narvik, hehe. Look here:
http://www.lofoten-startside.no/bilder01/sat-kart.jpg (Vågan was directly north of 'Borg' next to the coast ;) You might also call the region for Lofoten?
* Northern Norway - Tromso (The most northern town mentioned on the net and books is Steinkjær.. A small town far north up the fjord near Nidaros\Trondheim. You might want to call the region Nordland (North-land) and split the wast land between Steinkjær and Kirknes at the middle for both of them. And let Lofoten just be the island(s)?? Tromsø didn't exist at this moment..)
* Finnmark - Kirkenes (Never existed at hat moment, maybe those blue clowns we call Sames had settled there to breed their reindeers..)

Anyways!! I've researched all that for you, I'll hope you'll use it

And one more thing.. Will there be Wonders?

Cheers the viking
