From what we have seen of Fantasia, what seems to have merged is the corporeal world and a shallow layer of the astral world—not the complete thing.
Hmm it does make sense for what we've seen, not disagreeing with your point but I thought it was the entirety of the astral world, specially after seeing the images of the god hand member and it's surroundings I thought it was an indicative that these deeper layers where merged together. They being the "God" Hand it should be closer to the Vortex of Souls and the Idea of Evil than to the shallow part with the fantastic creatures we see up to now.
Afterall, the complete astral world includes the Abyss, the Vortex of Souls, the Idea of Evil, the Four Cardinal Kings of the World, etc.
Yeah, and I do believed they were all included, but we just didn't saw them already(feel dumb to believe a thing not shown, but that's theory speculation..), as for all the other 4 GH, I believe they are from a deeper layer than of the Four Cardinal Kings for instance and they where shown during the Fantasia first appearance. Who else then magicians know how to 'contact' the Cardinal Kings that may oppose the GH at some extent? The same magicians hunted by Griffith apostles
As for the Vortex of Souls, God of the Abyss and the Abyss itself, I always imagined then like a bottom of the Astral world, or if there are planes/layers within it, then it's beneath everything else, being the vortex a drain to the Abyss, and the Idea of Evil right at the Abyss entrance. It's more of a way for my mind to put shape to an abstract thing, but with that in mind I think it's possible for the complete Astral World to be merged into the Corporeal but not include those three things, only maybe a way to access the Vortex physically(probably I'm overthinking that last part as I write this).
I do tend to think that we're past the point of needing to see, as readers, another (new) sacrificial ceremony.
Absolutely agree, even if each one may have its own particularity, as Ganishika's had but was barely shown, it's not necessary to add redundancy to it. But still we know from Skull Knight Beherit Sword that Beherits can be used other way than the sacrificial ceremony, and I think that Becchi will be another exception of Beherit use.
This was never possible. Flora explained it to Guts in volume 24. You can't activate a beherit, it's the God of the Abyss that chooses when and where it happens.
Sure, that was exactly what I was trying to say by "
Puck influence over Becchi probably have already changed it's primary way of activation", that the God of the Abyss can't activate it anymore, of if it can then the final result will not be the same as to transport people to that "plane" of the astral world we've seen with the count.
But explaining better my idea(pure speculation), maybe there's a possibility that the Elven Od put into Becchi by Puck have filled the Beherit with enough counter balance Od that it can be manipulated ate some point by white magicians, as it's explained that bodies of similar Od affinity tend to congregate, maybe Becchi can be manipulated in order to be activated and not even Flora knows that because there's no precedent for an Elf living so close for so many time together with one of those, or at least if not activated then the activation can be bended in order to change the portal destination, duration or behavior. Anyway I believe that Becchi will not be used only as a portal to the God Hand.
This is a question rather than a comment
Yeah, more of question since I'm speculating myself without a full theory made haha
since the beherits open the dragon's path that leads deep into the astral world, they should still work even when the two worlds would be completely merged? A path is still a path. Although, as Walter said, it's irrelevant for now.
I completely forgot that Gedfring mentioned that, did not put into account that the "portal" the Beherit opens is actually a Dragon's Path(or is it Road of the Dragon?) leading the the Abyss. But now that the World Three is fully manifested, will the activation made people physically travel through its branches? Like being sucked through it. When we saw Sonia leading the apostles through the branches path, they still taken some time walking on it before getting out to their destination, even if they walked hundreds miles in a single minute it's still not instantaneous how the Beherit activation. Little detail with the same final result, but these second of difference may not be irrelevant since we know it's dangerous to get lost in the paths.
