The FFIX UOG say that Terra is located in the core of Gaia. If Kuja blew up Terra, Gaia would have been destroyed too.
lol The Crystal's old argument...
You know, I asked him several times for the actual translation or scans or anything and he never once provided it.
Oh and just FYI, you can't even get to Terra from Gaia normally. It's sealed off magically. So, how exactly do YOU or that poster know that would happen to Gaia if Terra was destroyed?
In fact, IIRC, I heard the Shimmering Island is in bits after you return. After Terra was destroyed. Maybe it's the after-effect.
This is proved by Kuja in the Crystal World, when he said that the process of assimilation between Gaia and Terra was already begun, and he couldn’t do anything to stop it, even if he tried.
Not exactly. The souls of Terra are already in Gaia. but Gaia still has enough of its own souls that is isn't completely Terra. This is why Kuja says
Hmph. You honestly think you can beat me? Even if you do, Gaia's already doomed. Its assimilation by Terra has begun, and the Iifa Tree will incite a cataclysmic destruction of Gaia.
And Garland
Garland: Even now, the Iifa Tree blocks the flow of Gaia's souls, while it lets those of Terra flow freely.
Even if Terra is destroyed, the souls of Gaia are stopped while the Terran souls already present flow freely.
