The World(False) of Atlantis anyone?
ATLANTIS
To immediately get it out of the way:
Atlantis itself is classified as a False Texture to the actual Texture that is Olympus by Holmes
here.
For those who want to know what Textures are indepth, see
here but to put it in brass tacks:
Holmes:
A satisfactory example, Miss Kyrielight.
The Tower stands at the end of the world, and its administrator wields the lance.
The question is, why does the Tower pierce the planet?
There is a theory that our world — the human world — is nothing more than one of the textured layers that wrap the surface of the planet, like a carpet.
To the planet, this is the consciousness of the intelligent lifeforms that reign supreme. In other words, our physical laws.
The “carpet” that maintains the laws of physics is our world. It is stitched to the planet so that it does not peel away.
This seems to be the phenomenon called the Tower of the End. It is also not limited to Britain.
There are multiple such pillars located throughout the world. One is the holy lance in the hands of the Lion King.
While of course, I can go into the people of Atlantis, I can't go too into it as it basically will pile onto Olympus so I'll only leave the main tidbit instead for the overall mentality:
Here, the people of Atlantis are so removed from the Gods, they will even prostrate themselves to a Terminal of Artemis without a second thought.
Here, when they refuse to leave the island, Mandricardo believes it's due to them being too used to the Island when in truth, it's because they are so starved for attention they will even take Artemis' attack as them finally getting their attention.
Here, it's explained that they are "defects" abandoned by Olympus and thus, getting any attention from the Gods is basically worth it.
Here, we find out the textiles their clothing is made of is from Silver Birch Bark embedded with Theos Klironomia.
Here, she later expands that the clothing is capable of regulating temperatures and has a coating to deal with blades from Demonic Beasts.
Here, we get a demonstration of that when Holmes states he felt nothing like it before then uses a well honed, well sharpened iron knife and can't cut through it.
Here, Goredolf wants to try and uses all of his might to try and cut the clothing but the owner states all he's going to do is ruin the knife.
Here, we find out that the Humans here are capable of not only hunting Demonic Beasts but even a Hydra as big as an Orochi or D'vayol Tron(Which are honestly nice comparison tools considering the latter can easily level a whole village and the former has issues with even okay Servants fighting the fragments).
Here, Holmes points out the blatantly obvious(So obvious that I shouldn't have to say it).
Here, Holmes and Goredolf compare how difficult it is for Yaga to defeat the Demonic Beasts even with Magecraft Buffed Guns and their own amped statistics vs. the Humans here who basically have no issues hunting even Hydras easily.
Here, it's also shown that these Humans can live for a very long time(A later scene tells us that 2 seeming Young-Middle Age Adults are actually close to 500 years old) though they still do ultimately age, just at a massively slower rate.
Here, it's stated that youngsters from the Lostbelt compete to see who will be chosen to defend Olympus.
Here, one basically believes you will be treated nothing more as cannon fodder but the other disagrees saying that serving the Gods that way is better than just being outcasts and they are "too old" to get in.
Here, Mandricardo explains this is due to the Klironomia in their system and clothing that "Since it allows Servants to be able to use their Noble Phantasms, it should be able to let humans live for 500 years"(Really should tell you how much magical energy it takes to use a Noble Phantasm at all and how much Magical Energy Servants have access to vs. how much that will benefit a normal human amongst other things).
Here, some of the Islands are basically either made of or has a huge amount of debris from the "Fallen Gods"(Most likely from the Olympiamachia that occurred).
And... that's pretty much it. I covered the Machine Gods Artemis and Poseidon earlier alongside the Atlantis Border Patrol and Echidna already alongside the main spawn she uses. Other than that, there isn't really much else to use(Astraea is ultimately a nobody and outside of one Event, she does get much at all so no point in adding her in) so...
