What's the point with that quite lackluster story in Endwalker?

[KageTokage]

I think familiars/arcane constructs are generally distinguished from living things by the fact that while they can have minds, they don't possess any of the other traits typically required for something to be considered "alive" like a functioning biological anatomy (Meteion being mentioned as not being able to eat as requiring sustenance would've been a detriment to her purpose of traveling the stars), which is also one of the requisites for something to possess a soul in the first place.

It still raises an icky question of morality if those beings are still able to feel pain physically or emotionally, though...
