As for Claire's current precarious circumstances, aka the Spirit Artefact of the Lumyst Chalice, this was a little more complicated. During the battle against the World Eater, the chalice serving as her vessel, along with her spirit, had shattered, scattering fragments across space. Thanks to the gravitational pull exerted by Klayr's corpse, these fragments mostly fell back onto the future world-plane, crashing all over Twyluxia.
Long before his death, Klayr, like Jake, had developed his own Inner Space, a dimensional pocket nestled inside his body and accessible only by him. Of course, it was incomparably larger. This was where he housed the non-combatant cosmic monks of his order or his own Floating Island when it still mattered to him.
We've finally wrapped up the lore. We'll return to the present in the next chapter. It took longer than I expected, and I still don't know if I revealed it in the best way or if I said too much. It seemed indispensable at the time. In hindsight, some information might not have been essential for understanding what comes next, or it could have been revealed at another point, but it is what it is. Anyway, enough talk, the action returns soon.
