As you may know, in Norse mythology, Yggdrassil, the world tree (which would be known in the One Piece world as the Adam tree), is divided into 9 realms, with all of this realms being separated from each other. We just discovered that Elbaph is actually divided into 3 realms instead of 9: The Heaven realm, the Sun realm, and the Underworld/Hell realm. The first one being where the king probably lived, the second one being where normal giants and warriors live, and the underworld being reserved for the worst criminals and the most dangerous beasts on Warland.
We also recently met Loki, which is a strong character that already showed how dangerous he might be with his conversation and deal with Luffy about being liberated.
Now, as you may remember, Kaido used an attack against Luffy (after he got Gear 5, chapter 1045 and episode 1072) called “Conqueror of 3 worlds: Ragnaraku”. The “3 worlds” part of the attack always sounded weird to me, because if he just wanted to show how powerful he is, why not do something like Zoro and say “1 billion worlds”, or just say “9 worlds” in reference to the 9 realms that Yggdrasil has in Norse mythology? But now, we know why.
He named the attack like that because in the One Piece world, Yggdrasil/the Adam tree only has 3 main realms/worlds. So, Loki is already the most important character in the underworld. With how Kaido’s attack is named, could this mean that Loki’s plan is to destroy and conquer all the worlds in Elbaph, causing their “Ragnaraku”? This is more important than it seems at first, because this may be a similar situation and a parallel to how Luffy was said to be going to “destroy Fishman Island” in the future.
Maybe, Loki’s plan is mandatory for the world of One Piece to be liberated so the “Dawn of the world” finally happens. This would also explain why Loki calls himself the “Sun god”, being another key part of the liberation of the entire world like Luffy is with his Nika powers. In fact, all versions of the Ragnaraku that we know of are caused by fire, usually by the jotun “Surtr” with an enormous blade that will set the entire world in flames, which, again, may establish a connection between the Ragnaraku (which is also called Ragnarok in the original myth), Nika the sun god, the dawn of the world, etc.
So, Elbaph’s plot will show us how Loki is viewed as a traitor and a villain, trying to destroy the world and kill everyone because he is “evil”, but we will end up learning that, for some reason, Loki NEEDS to become Elbaph’s king and conquer their 3 entire worlds, so that the “Ragnaraku”, the end of the world (and in this case, the end of the long “night” the World Government created) can happen.
This would also mean that Loki is not a real villain, and more like a temporarily antagonistic figure who will end up helping the Strawhat crew after this arc ends, leading up to the final war against the World Government and causing the end of the current era, with Loki’s plan being the first step we need to take to achieve the “Dawn of the world”, marked by the destruction and purification of everything that came before.
Tldr: Kaido’s attack “Conqueror of 3 worlds: Ragnarok” is a foreshadowing towards Loki becoming Elbaph’s king and not being a real villain, while also being an old foreshadowing about how Elbaph wouldn’t have 9 realms like Yggdrasil had in Norse mythology, but 3, meaning that Elbaph will end with the beginning of the Ragnarok, and the dawn of the world, which means that Loki isn’t actually a villain and probably will end up being Luffy’s ally by the end of the arc.
