thanks for sending over the files!
I tested the save and it looks like you had a very unlucky worldmap generation. There are 4 undead locations close by and all are generated with a lot of enemy troop points, that is true.
However, there are other locations around that are manageable, like a hut with 4 Orc young and similar but you happened to not find those.
The enemy troop composition will change whenever you engage a camp as camps do have a troop point pool that they use to “buy” units. The units themselves are not fixed. This is so that the camps can get more points as the campaign progresses to increase their strenght without being stuck at certain troop compositions.
The locations that are generated outside of contracts do not scale that much to player level so some of them are not beatable in the early game. Most do hold great treasures though that have to be guarded by according troops.
In your Save you could try looking Northeast of Krauchwall or Southeast of Hohenwacht for smaller enemy Camps. Enemy camps are constantly generated throughout a campaign so the situation will change later as well.
