The Role of Necron (Spoilers Abound; Read At Your Own Risk)

[Squall of SeeD]

Okay, so Garland wants a world where life and death become one.

Not quite:

Garland: "That is the dimension in which we are meant to live, as beings that transcend life and death!"

(Bolded for emphasis.)

He speaks of transcending the two. Necron's words would suggest the transcendance of life and death, as well. With no life, but still existance, there's no death either. Without life, death cannot follow.

And there's still the fact that Garland couldn't have created something that's always existed.

A fair point, though Necron wouldn't have been the first villain to exaggerate.

Any way one slices it, the Necron situation is Plothole Land. I'm seeking the explanation that is based on the story alone and not on things outside of it or not suggested by it. Granted, even that leaves a few questions unanswered, but it's more reasonable in my opinion than looking outside the story.

By the way, if Necron had no connection to the Tree, why did it die after Necron's departure? Garland stated that the Iifa Tree's true form wasn't the Tree itself, which he called its material form. Where would this true form have been? Obviously it would have been a form not on the material plane based on his wording. When, then, would this non-material form have been contended with otherwise?
