That's basically what I was inferring. You just did it better than myself. Memory even if I quoted it for loose interpretation (Insight and Knowledge of things unseen) probably wasn't the right word to use. It's all speculation for me at this point as I haven't spent the time needed to really dig through all of the items, notes and locations to try and piece it together. But it would help explain a lot of things.
Edit: Regardless, even the worst interpretations, such as mine can help others to shape and refine their own, so I don't think it's without merit. So thank you for taking the time to respond.
I dont think theres any bad or good interpretations, we all just put forward what we think, try and support it and a vague picture sort of forms. Which is where the fun is really. In a way the official lore chapter is going to kill a lot of that. I do much prefer the idea of it all being manufactured memories rather than a flatout dream, reminds of Dark City and such.
There's just a lot to suggest otherwise.
the Ashen blood originates in Old Yharnam.
Old Yharnam holds the Pthumeru Chalice discovered in the tomb of the Gods
Are you suggesting that the Pthumeru chalice is responsible for the ashen plague? Just because A came from B and C was there doesnt really suggest a causal link between A and C
Chalices are explicitly objects used for worship of the gods.
The only thing the game tells us regarding chalices and gods is that a chalice can be used to open the labyrinth of the gods:
"Ritual chalice found in the Church of the Good Chalice.
Use in a ritual at the tomb altar in the Hunter's Dream to break the seal of the old underground labyrinth.
Let the chalice reveal the tomb of the gods; let blood be the hunter's nourishment.
...And let ye partake in communion... "
Nothing there about worship, unless its one of the other chalices that mention it?
And Amydala holds another chalice. Which refers to Loran, another city that fell to beasthood. And there's a lot of runes that suggests beasts also find their origins from the tomb of the gods.
I cant quite see a causal link between Amygdala having a chalice and the Great Ones being responsible for beasthood. The Great Ones certainly seem responsible for leading/inciting people to blood ministration, but if, as posited above blood ministration inevitably leads humans to beast hood then the fall of Loran to the scourge would be an inevitable consequence of Blood ministration. Theres also a total of one rune that mentions beasts and the labyrinths as far as I can see and its (like most of this stuff admittedly) open to interpretation
