That's odd. After speaking with the people in the mill you should be able to enter the stree-uhk villiage. Shoot me a DM, I may need to take a look at the save game.I've just started playing, but I seem to be doing something wrong with the Aggro-culture quest. I need to go attack a village, I've been told it's on the south west of the map... I can see there is something there but the game doesn't let me enter it!
Edit: Dunno if I needed to be certain level but I've got in now
