Not sure if I gone crazy but almost everytime I go into mars portal I notice a couple thing. One is the fact that the middle platform is gone and there a weird bridge off in the distant that can be accessible via melee with shield. In Venus portal I notice that the middle platform is complete and that there is light above the cave (could mean light). I also learn that the atheon area is associated with atheon (Just like how crotas area is crotas face when look down at it: I discovered that) but only different is atheon area is not a face or arm but rather it name. The area is in a shape of an A.
