Or maybe we should shoot the pyramid?
Hmm.... I've theorized this area is a detailed recreation of a battle complete with attack sites and markings for active military units. The pink Floyd tie in is noted but it's significance I think requires more thought. The triangle in itself is a Prism... that itself may be significant. We got the Prism system of Drew lore, but also prismatic shields. Then again it could be trying to reference some sort of light amplifying weapon. Finally I won't rule out some odd tie in to lensing on a cosmic scale.. gravitational lensing from stars etc.
Exciting stuff.
