It's interesting that someone autistic and condescending enough to search discussions from 6 years ago doesn't look to see whether or not I was participating in it and earlier conversations. Yes, I remember. Conversations about this game go back to prior to release, including the betas which I also played. Also, newsflash, pretty much every discussion on this site has happened before, Captain Bladerunner.
What are you talking about? You don't participate in the conversation I linked to (which I did because I thought you might find it interesting). And how am I being condescending? I genuinely thought you were playing PoE for the first time. I'm sorry?
Fair enough, it's entirely possible I misread your "tone" and point.
The thing is, there are many POE threads besides this one and there have been many discussions about the themes, the rules, the x, y, z. Just like what is an RPG, what is the meaning of Bladerunner, and many others, this discussion has happened more than once. There's nothing new under the sun. Either way, my point was mainly, sure but the conversation happened
SIX YEARS AGO (and I probably read it back then, but thank you). That it's happening again with perhaps some new viewpoints and other participants isn't really a big deal.
Anyway, you're right that the Engwitheans built the machines (I won't comment on any revelations from Deadfire because I haven't played that yet, but likely will in the near future), moreover, they built them to manipulate souls and to create the Gods in the first place.
I think where things get a bit convoluted is that in a real sense the Gods are subordinated to mortals which is why the Leaden Key is concerned with animancy since soul manipulation could allow mortals to undo the Gods, change them, or otherwise oppose them. But in another way, Thaos was benefiting from having created the Gods since Woedica was assisting him with his agenda. It strikes me that this is less like a traditional divine patron and more like building a wrench or a robot to assist you with whatever you're doing. People build tools to do what they're unable to accomplish on their own.
