Defence Is Their Top Priority
The one who Hye listened to her opinion the most was Isac, and she with others drew a rough plan of the general design of this area.
Against what Hye thought initially, they agreed to place the planets at the border areas of their new home. This would serve better as defensive bases, and frontline military camps in the future. As Isac said herself, protecting this place was the top priority for them, then inhabiting the entire area came second.
Hye didn't argue or object to that. Any infiltration or damage would have a much worse impact than slightly delaying the plans of inhabiting this area. Not to mention the main bases for Hye right now were his Earth and second Earth planets, not here.
Not to mention he needed time to gather more people and move them here. The population he had back at the two worlds was growing insanely without a doubt, but they weren't enough to even fill five planets out of these going to be built here.
