I was going back through some lore recently and it just hit me.

Sefirah Castle gets introduced early as this weird gray fog space Klein stumbles into. Then slowly over hundreds of chapters we learn what it actually is. One of nine Sefirot on Earth. A legacy of the Original Creator. The gray fog is literally a realm of god that comes with it. That slow unraveling is one of my favourite things Cuttlefish ever did.

But then I started thinking about the other eight and kind of just sat there for a minute.

Because we barely know anything about them. Like at all.

The Chaos Sea at least has a real world entrance. The City of Calamity is an entire city existing as a Sefirah, what is even happening inside it? The Country of Disorder is a whole country on the same level. The Mother Nest has a name so unsettling I genuinely don’t want to know more but also desperately do. The River of Eternal Darkness is apparently completely hidden somewhere unknown. The Tenebrous World ties to the Father of Devils. The Wilderness of Knowledge is an entire wilderness. The Key of Light pulls in Buddhist cosmology in a way that feels like a whole other novel waiting to happen.

Six of them came from the Original Creator himself. The remaining three from Outer Deities who are his direct descendants.

Klein spent his entire journey living inside one of these things and we still took forever to understand it. These eight exist at the exact same cosmic scale and most of them get maybe a few paragraphs total.

Cuttlefish built a world way bigger than the story we got to read and honestly that might be what I love most about it.

# COI readers do any of these get explored further? Spoiler tag please, there are newbies around.

[LotM V8] We spent 1300 chapters inside one of the nine Sefirot on Earth and I just realized how little we know about the other eight
