Earthly cycles have always controlled these beings, regardless of the illusions that the human species prefers to delude itself with. Through their overindulgent faculty of thought, they have confused what is real with their conceptual understanding of what their five senses can perceive. Fooled by the filters behind which they live, they truly are. Come what may, in all fairness, invisible sieves, such as the biowalls that protect their coastal havens and the personal bioshields that act as finer frequency membranes, do serve to protect their three-dimensional forms from premature transcendence.
Other defenses are futile.
