1) We don't really know, although IF it is Murtaugh, then there are good reasons for the people not to be close to him. Murtaugh is a misanthrope and a recluse, so people aren't likely to be close to him. Besides, them being close to him would be counterintuitive for the purpose of exploration. There are similarly good reasons why he might make a barrier to shield himself. The net is out to get him (and all humans)WorldisQuiet5256 wrote:I'm wondering if there are more than on Defense System in Layer 1. Here is my reason why:

If the Submachine see Human as an infestation or at least the on who join Murtaugh and all of their present location is on this Map. see the Core or where the C is that labels the Core, now see the area around it where the possible Defense system were in around the Core, there is another similar apparent Barrier just bellow it at 7 o'clock. Now if that is a Defense System then Who is in the Center of that, is it Mur? Plus why is there a Second Defense System in Layer 1? What is there or was once there that was important enough to have it own Defense System?
2) The secondary defense system, if we are talking about the same thing, is evidently shielding the Edge from being attacked.
