Hey I was just goofing around and i figured out how to get into the other provinces. Ok first just go into any city like Bruma or Chorrol ect... Then use paint brushes to get over the city wall.(the paint brush glitch is listed somewere around in the forums.) Then head toward any province (it will be very glitchy and you will be able to see through the ground but its ok). Now the hard part is climbing the mountains that block your path. After you do that you can go as far into the province as you want. Oh but you won't see anything but trees and glitchy stuff. Well there is something to do hope you have fun.
Come see me at the ElderScrollls4Oblivion forum, im always there. Why am I always there? Because its the greatest forum ever thats why.
