I found this last week while coming back from the Gatelord area and was puzzled by it. As soon as you hit Campus 9 go straight until you hit the first vex gate and look down and a bit to the right. It looks as if it comes out of the mountainous area we are propped up on. Maybe just maybe like .000001% it's going to be an extension to VoG down the road.
Edit:I get that it's a skybox, but whom says i can't ask questions about what is it, what was it, why is it there, it's purpose. I guess that's why so many people bash on Destiny because the can't use their imagination to think outside of the box.

It's not our lack of ability to think outside the box. Video games, especially open world ones... give us the freedom to truely explore outside that box. Destiny does not.
