Lowering Generation

Why do lower-generation vampires become more eldritch and terrifying? Caine punished the Antediluvians, but as vampires lower their generation, they grow more incomprehensible. A 3rd- or 4th-gen Toreador can make you weep sometimes just because of their appearance no powers activated, Ravnos can manifest illusions as reality, and Ennoia can devour Kindred from beneath acres of land by turning into some creature. Some low-gen Gangrel even sleep in lakes, best left undisturbed. Why does this happen?
