Okay, so I was thinking & the thought crossed my mind that maybe The World That Never Was is what used to be The Keyblade Graveyard. We've yet to see the remains of the great Keyblade War since BBS. I was thinking that maybe Xemnas knew that the Keyblade Graveyard was the only place the X-blade could be forged, so he built his base of operations on this barren wasteland. It is said that Xemnas built TWTNW, but surely that means he just built the dark city, not the entire world, because the whole point of conquering KH is to build new worlds & shape the universe to how you see fit. Another reason I think this is because it seems to be the only place all XIII incarnations of Xehanort can coexist, or maybe that is just because it's special world like CO, MT, or LoD, but KG was also a world in between, so I still think it's possible that Xemnas purposely built his HQ here for Master Xehanorts return. That's another thing, the KG is where Master Xehanort gave up his old body & his old body is what forms in TWTNW, you're supposed to come back to the place where you lost heart. I know he didn't lose his heart here, but I'm just trying to support my theory. So, do you think TWTNW could be what was the KG or do you think that all Xehanorts can exist in any world in between? Or something else entirely?

Wow, I actually never thought about it like that!  It's true that Xehanort perished in the Keyblade Graveyard, so why did he get revived in The World That Never Was?  It could be as you said, but remember that all his incarnations were there, so maybe that helped him to revive in TWTNW.  That is all a mystery, but you know, if your theory about TWTNW being the Keyblade Graveyard proves to be true, that'd be mind boggling.  It's very interesting to think about!

But wait .....haven't we seen a part of Keyblade Graveyard in Kingdom Hearts II Final Mix ?

Yea, nick we have indeed, we have seen the Badlands of the Key Blade Graveyard, where we fought the Vanitas Lingering Sentiment in Birth By Sleep Final Mix and where we fought Terra's Lingering Will in KH 2 Final Mix. So i am sorry to contradict all your hard work and effort NO_HEART_XIII but it seems all of this information can be scratched just by fighting the Lingering Will in KH2 Final Mix, i did like the theory however.

You may have contadicted everything I said & that's okay, now I know my theory probably isn't right. But didn't that fight take place in the past? I thought the portal led to the past. I haven't played Final Mix so I can't recall. I guess if TWTNW was the KG then the bigger question would be what happened to the Lingering Will? I personally hope the KG is still there, because that place is cool.

I had this theory a year ago. and people said it didn't sound good at all.

They just don't get us. Lol. But they're probably right. If the portal in KH2 didn't lead to the past, then I don't see how TWTNW could be the KG. However, if it is, maybe Xemnas had Terra's armor locked away just like he did with Aqua's armor.
