I'm having a hard time grasping, conceptually, what the Perfected are, what a proto-hive is, and so on. I'm getting vaguely Borg vibes, but the descriptions in the books seem ... very nebulous, other than stats. Similarly, other than "vaguely biomechanical humanoid," I can't really figure out what they look like. The xenomorphs have the advantage of the films and books, which we've all seen (and most read), and I think the descriptions of the Perfected are feeling that lack.
I have all of the books. Am I just failing my Observation roll?
Does anybody want to take a stab at explaining the Ecology of the Perfected?
