Time passes as your flight of helicopters delves deep into the Mountains.
None of you have ever been this far out on a mission before; this far away from the hardlines, equipment... safety. Nowhere to run to in here. If anything happens to the ships, none of you will have a chance.
Under Ariadne's guidance, you head towards what she thinks is the right place. And after some time of flying, something unusual turns up.
Between two mountains ahead of you, there is, connecting them, an enormous wall, as high as the mountains themselves.
"The plan is that someone tells me what the hell that thing is!" says Dallas. In a flash, he is on the phone to Ariadne.
"Why in the hell didn't you tell me the King of Walls was coming up?"
"I... I don't know! It doesn't read like a wall, it reads like mountain!"
"What? It's all stone!"
"It's coded like mountain. There's differences!"
In fact, it is not just those two mountains that are connected. The wall goes out and around and back from the edge of it you can see. In fact, as you gain height to get a better look (difficult- you are pretty darn high as it is and helicopters aren't built for that much altitude), you can see that the wall actually forms a vast circle.
Something odd, though. Thhe wall is at a constant height, which is to say how tall it it varies.
To explain- the top of the wall is always at exactly the same height, relative to sea level. So where the mountain is low, the wall is very tall to reach up to that point. Where the mountain is high, the wall is very short, all it needs to be to reach that high point. In fact, some of the mountain peaks reach above the height of the wall, and there the wall does not exist at all- instead, there is the strange look of pinnacles of rock sticking out of this wall of uniform height.
