Requiems interior is confusing to me. I assumed it was a Shield World like the one in Halo Wars, but then we go inside the core, and its a smaller sphere. How does that work? When you look at the skybox in any of the missions ior maps in Halo 4, you never see the core (I don't think). It'd also be nice for someone to explain to me how the Core destabilized at the end of Foreunner(?), but then was never mentioned again. Seems like a preeety major plot point to me, but apparently it wasn't.
