Yet these mantles manifest themselves through frost and blossoming flowers. If they're inventions of human sin, why aren't Summer Queens followed by streams of blood? Why is it that howling winds- not dying screams or tortured sobs- herald the Winter Lady's arrival?
Because the Mantles show themselves through clear natural phenomena, we may assume they are creations of nature. Natural creations? That remains to be seen. But there are plenty of situations where nature establishes a symbiotic relationship with human life and humanity's 'artificial' constructs.
Why didn't using the red court's bloodline curse, powered by human sacrifice, drive Harry insane? For whatever reason, we have situations where sometimes something created by black magic is innately tainted, and others where it is not.
My point is not that mantles secretly have goatees. My point is they are artificial constructs with a finite amount of energy. Whether they were created by petting kittens or murder.
When Harry killed a man to protect his daughter, that was also nature. A natural instinct equal to any falcon call or palm leaf. Remember what his id said? "Protect the offspring."
Man is an animal and part of nature, sure. And a beaver will construct a dam just as man does. The difference in these things is the scale of consequences when what man (or beaver) creates inevitably fails.
Humanity itself endures. The towers and dams don't matter, they're just byproducts of life- human life. Judging us by dams is like saying all Dalmatians are going extinct because dog shit can be washed away.
I think it is a question of scale. Man would not survive the beams or Tower falling in The Dark Tower. It would end all life, all reality, every universe. Just like that. Man did not build the Tower. The Tower as such is a fictional invention of Stephen King, but it is also a metaphor.
Yes, the Hoover Dam breaks, very sad, but Soviet Bear marches on. It is not an extinction-level event.
Something goes wrong with the fae queens, the weather gets messed up. Likely to kill more people than Hoover Dam from SK's description, but again, it's not like climate change is an extinction-level event or anything, amirite?
But is weather alone the only way fae queens have intimated themselves into natural processes? Is that their worst failure mode? And what about the dragons, if they are mantles as well? What about Hades, and his prison of souls? What would be the consequences of that dam breaking? We already know from the text that Demonreach's prison and the Outer gates are two "dams" that woud destroy us. Granted, those latter two are not natural processes being usurped, but they remain systems with entropy.
Humanity may survive many of these things. But past a point, the consequnces would be an extinction-level event. Maybe not necessarily the end all of realities like the Tower falling, but as far as we're concerned, game over.
