Let's talk aliens.

Essentially to defeat them one would somehow need to disrupt their telepathic network and use that blackout period to cut out each "finger" so to speak and their energy sources/supplies which seem to be critical to it. Surely this doesn't look as easy as activating an artifact and hoping a wormhole would suck them all. Well, predictably not all of them were thrown out like that. Problem is that said telepathic network does not manifests itself in the world outside of living beings, hence why machines and nomads cannot communicate to each other. Both can detect physical manifestations of each other with sensory organs/devices but that's all there. So how does it really work? And if that telepathic network really exists... where would it be and what would it be like? Either way that is their Achilles' heel. Questions, questions.
