I think I have figured out the stalactites!

So, those stalactite things that are apparently hanging down from the ceiling of the shield world? WELL THINK AGAIN!

Look at the new Bulletin and click on the xbox dashboard theme picture that has the stalactite things as the background (the picture is near the top of the bulletin).

Now that it is pulled up, (tilt your head or do whatever) but look at the picture UPSIDE DOWN!

Does it not look like a cluster of buildings forming some futuristic city?

I get that so far we have only seen them from the ceiling and that chief’s orientation has always been opposite of the stalactites, but what if the two different areas have different gravitational pulls (in some weird sci-fi Forerunnerish way). The idea totally blew my mind.

It honestly DOES look like a city. It even has clouds above skyscrapers and everything you might expect from a Forerunner city.
