In the west, only Urak had a significant army, but it seems he lacked funds. I used a blitzkrieg strategy, breaking through into the country and discovering a large number of unhired creatures in the captured castles, including archangels, which decided the battle against Urak. After that, all the rulers, except for the green one (whose army came from the northwestern ramparts), had practically no armies, while I already had both an army and good stats. I spent more time chasing them around the map, trying to figure out where the other cities were hidden.
Regarding the bug, it might be related to my system because I vaguely remember when I was playing the standard Vikings campaign, there was a moment when, after a battle with one of the purple factions, my stats went from around 40 to around 13. I had to play from a very old save, but the bug didn't repeat.
