Looking at Bruma in this case not only is it right on the border to Skyrim making it easy for word to travel between Cyrodiil but Stormcloak rebels or in the case of a Stormcloak victory for the Stormcloak Armies to get across. Not only that but in Oblivion there was a huge Chapel of Talos and with the ban on Talos worship this would have a huge impact here.
So I just wanted to get some options on what other people think the effects of Skyrim Civil War could have on the rest of Tamriel not just Bruma. So feel free to post.
