So, the best solution we have for this problem is natural borders. By natural borders I mean mountains, rivers, etc.
But in the category of natural borders, why haven't they thought of cliffs? Giving the player an option to move forward, jump from a cliff. Of course, if you do that you will also die. And it makes sense in Skyrim! especially in Skyrim! Why? Because Skyrim is a very high place, with lots of mountains around, and it doesn't have to be surrounded with mountains, the entire continent can just be on a very high level, which means that when you reach an end, you'll find yourself facing either a mountain, a river, or a CLIFF.
