Kingdom Hearts II Chasers from Oblivion?

I was just typing a response to a different thread when I was struck by inspiration (and this one actually makes sense, somewhat!)

Okay, here's my thoughts on Castle Oblivion, first:

The world of Castle Oblivion was once a densly populated world where people of both light and dark hearts lived, and scientists like Ansem the Wise searched to discover the meanings. But rather than studying the heart and searching for the Door to Darkness, they dove into the bowels of the mind and searched through men's memories.

But, as explained in Chain of Memories' Halloween Town, a person's true memories could drive a man into the depths of insanity. And, true to this, the great minds of the world began to fall to their own memories, eventually leading to a world of abandoned wasteland.

This is why when Terra, Aqua, and Ven approach, they find a barren wasteland.

And this is why, when later Sora finds the world, the same crossroads have been naturally overgrown with weed and grass.

Okay, now, when Xemnas creates Organization XIII, he learns of another world situated on the in-between world of Oblivion. He goes there and realizes that the Room of Awakening is there, along with Ven, the other "friend," who was never moved from that world after he was frozen. He also found that he could use the castle itself to play on memories. He decided to keep Namine there, as she also had power over memories, and he sensed a connection. The pods that kept Sora, Donald, and Goofy (as well as the others in Twilight Town that appeared to have been used before: they were used by the original inhabitants of the world).



Okay, that's my long theory about Castle Oblvion. Now, for the Chasers:

What happened to the inhabitants of the world after their memories drove them insane? What do we call Chasers? eh? eh?

Okay, think of this: Marluxia said that having your memories destroyed would cripple your heart. Couple this with the experiments mentioned before, revealing their true memories, and a Chaser is now born from the memories of a broken-hearted man.

Xehanort? Could Xehanort have spawned a Chaser, and lost his memory? Is this why he showed up at Radiant Garden? Is Xehanort a Chaser himself?

Yeah, I expect the next game is gonna deal a lot more with memories, like Chain of Memories did. Perhaps expand on what we learned in Chain of Memories.

 

Your theory isn't bad, but I doubt Xehanort was a chaser. If what you say is true, and Chasers are made of memories, they probably couldn't become Heartless.

 

Yeah, I guess you're right. But still, if my theory comes out correct (unlikely, my theories never are) then wouldn't it be plausible for Xehanort to come from a world where they studied and lost their memories?
