So I was strolololing through Skyrim's pretty landscape and decided to see where the path beneath my feet would take me, so I followed it. After a while, I passed Riften and found myself nearing the map boundary. I was getting a little excited at the prospect of somehow glitching out of the map and running around Morrowind and Cyrodiil, when I hit a wall. Well not so much a wall as a...gate. With an invisible wall. Here's a link

What's the purpose of this area? A clear way out with a map boundary in the way? I looked around and found nothing else, just this.

So my question is, forum: What?
