I think that whenever Lumian sleeps Klein takes him to the city of calamity that would explain the gray mist (as far as we know all the sefirot are on the eastern continent) and why Lumian is having access to the sefirot of COI they are linked. Is it a Klein trap for COI?

Thanks for the chapter

if you think the wheel of fortune path came from the cosmos being the only path stolen from an Outer God would explain why he can't switch to other sequels and on second thought the circle of inevitability has something to do with fate
