That'd be 81 major locations, which seems a stretch. Could be there'll be 9 settlements plus 5. Or 4 settlements plus 5?
Middle option seems most likely. Either way, a tad disappointing and less than the '20+ settlements' people talked about at the time of GameInformer.
Eighty-one major locations could include temples, ruins, settlements and much more. So, I suppose eighty-one
might be a fair number. Perhaps, there will be 20+ settlements in all of Skyrim with each of the nine Holds having political control over some settelments.
What do they mean you "don't approach it"?
Could mean anything, but I reckon either of these two is more probable:
1. It's a guarded outpost, hence outsiders are prohibited.
2. The PC doesn't approach it in the demo.
