Theory from discor
F
It is unlikely that the Huffpuff ring is outside Hogwarts. Since all of them are clearly designed to be found by their receivers. From that, it looks very suspicious that one heir should collect them bypassing the rest.
H
True. Perhaps the Sage in particular is meant to collect and distribute them?
Though I would think the Ring of Slytherin is meant to be found by the Heir and not the Sage.
F
The Ravenclaw Ring being found by the Sage makes complete sense.
It's the Gryffindor ring that's the odd one out. If the Champion is Hecate, she might have left it there deliberately for Neville. Though Neville might also have lucked out with Seer powers and/or Gnosis. "Just lying around on the dungeon floor" still seems weird otherwise.
F
For some reason I think Neville lied about the Gryffindor ring. Well, either there are vows of secrecy on it, or the ring was hidden by charms in a prominent place. But all this does not correspond to the ideals of Gryffindor and its champion.
Besides, the supernova also looks strange. If the star was a box for the ring, then why should it have a temporal effect?
H
Might have been so as to not out the Champion without talking to them first. But yeah, I find it hard to believe Godric would just let the ring sit on the dungeon floor.
There are creatures out there among the stars.
Letting the ring sit on a star might therefore carry risks, and need either wards of some kind, or just a timespell to have it show up for the supernova.
F
What if the forces behind Neville are the Ancients, not the guardians?
To be honest, Neville doesn't understand that we are one of the heirs, we are too talented. So after the story, he could ask.
Harry, are you by any chance the heir?
But he doesn't ask like that, he forces us to reveal everything ourselves, at the same time giving away our secrets. And what exactly we got from him in return is zero.
This is very similar to manipulation on his part.
Besides, why did he invite us to the astronomical tower during the supernova?
Perhaps he needed one of the heirs to correct his calculations. And since Neville is not one, he had to call Harry.
If this theory is correct, then I can even tell how Neville got the Gryffindor ring.
H
Stolen from the Champion?
Then why has he got an eidetic memory? Did he lie about the dream too?
He used the same terminology as the not-a-Dementor, at least, though that might be because Ancients and Guardians have the same vocabulary.
F
And the memory was erased
We don't know exactly what kind of memory he has, but as far as I remember, the text never emphasized that he remembers more than an ordinary person
They could have been one people, and I doubt that if the ancients want to create a spy among the guardians, they will reveal themselves so easily
H
True, but I doubt an ordinary person would be able to look up plants unknown to them from a dream more focused on a conversation.
F
It could be some kind of devilish snares that are difficult to confuse with something.
It may also be unnecessary details so that we get confused in the details and believe this story
F
There is also another fact in the piggy bank of theory.
Neville does not directly claim to be Ravenclaw's heir. He's just afraid to make a mistake because he's still not sure whose heir we are. According to external criteria, we fit both Ravenclaw and Hufflepuff, he is afraid of making a mistake.
