I wanna know how can they save Aqua Terra and Ven, i think that to save Ven they have to find Aqua first 'cause she's the only one who can open the that leads to the Chamber of Waking , so they have to save Aqua first, I Dont really know

 

If they were to save Aqua they would have to go to the realm of darkness right? how can sora or riku enter the the Realm Of darkness ?

And about Terra i dont really know nothing  i have no ideas about how they can save him?

 

so that makes 6 lights along with sora riku and mickey.And about the seventh,who is the seveth? : Lea,Roxas,Xion,Kairi ah who else could be ? 

 

i know that now one can be sure of how would it be because the kh 3 have not been even announced i just wanna know what do you guys think about it just your opinion and your theories, just to solve my doubts

Yeah, Aqua will be saved first. Sora and Riku could go to the Realm of Darkness the same way Mickey did, but I have no idea how

With Aqua, they can go to Castle oblivion, and she will be able to guide them throughout the castle, saving Ven.

There's no way to know if Terra is a Light yet, but I think he is. With Aqua and Ven they'll somehow manage to awaken Terra inside, and they'll free him.

I think something will happen and Kairi won't be able to be a Light Protector. I think Roxas will be a Light, because not only it's been hinted, the whole "Nobodies grow hearts" in KH3D is kinda of an excuse for him to have his own life.

He will come back, but there's still no way to know if he'll be a Light (though I hope so)

Roxas can have a heart as much as he damn well pleases. Doesnt change that he doesnt have his own body.

Well how everyone will get saved exactly is a mystery but generally it's believed that Aqua will be saved first probably reaching the RoD using a CoD. After that Aqua can find Ven's body at CO then his heart would have to be removed from Sora then placed back into Ven. Terra is still under Xehanort's control and it would be a matter of somehow removing Xehanort's hearts from Terra's body. 

 

Lea, Roxas, Xion, and Kairi are the prime candidates though at this point who all seven are is still a mystery. At this point Terra isn't one of the lights either. 

I'm very confused about the part you said: "After that Aqua can find Ven's body at CO then his heart would have to be removed from Sora then placed back into Ven." How Sora could survive with this? I mean, I know the hearts are separate and I wonder what would happen if Sora gives Ven's Heart in Ventus body? What secondary effects will happen to Sora? Do you remember what Data-Namine said about something she found in the deepest of Sora's Heart and she said that "pain" must be care with extremely carefully or something bad would happen to Sora? I'm really interested and confused in that part....... and I wonder How Terra will be save? agh.... Sometimes KH can be really a headache if you think about the story ¬__¬

Keyblade masters have the ability to remove hearts so if done carefully I'm sure Sora will be fine, they just can't go tearing into Sora all willy-nilly (looks at MX). Ven's heart never had much effect on Sora though, the only thing it did was grant him the dual wielding ability which he may or may not lose. I don't remember Namine's exact words well since I haven't been able to play Re:Coded in a while after I lent it to a friend (who I must hunt down and kill) but I think it was more of a prelude to 3D? Sora was never good with dealing with pain and when something bad happened he'd brush it off with a goofy grin and being gung ho about saving the day but he never learned how to deal with it proper.

 

Because of Ven's heart being inside him (and Roxas and Xion) Sora also now has a slew of painful memories that don't belong to him and that he doesn't know how to deal with. I haven't played 3D (so correct me if I'm wrong) but from what I heard the antagonist tried to manipulate those memories to try and have Sora sink into darkness (e.g. Vanitas appearing because Ven's heart was stirring) and by the end his heart was a bit damaged. So yeah, if not handled properly the memories in Sora's heart can be damaging to him. I don't think it'll be from a direct result of Ven's heart being removed (unless it get brutally torn out), it's more if it gets manipulated while in Sora.

 

Terra is a whole other can of worms, lol. 

Ven is asleep. Sora has his heart. Aqua is simply in the Dark Realm..Mickey, Riku and Lea have all used the dark corridors. It will literlly take them about fifteen minutes to get her. And with her, they can navigate Castle Oblivion. Then they take Ven and have him and Sora do their thing.It's Terra who's a bit tricky. I don't think they can get him back until Xehanort is defeated.Which leads me to believe it's gonna be Sora, Riku, Kairi, Mickey, Aqua, Ven and Lea who will make up the 7.

Actually, it is shown in KH2 Riku can no longer use CoD. Mickey was never said to have used the corridors. And personay, my Light list is:SoraRikuKairiAquaTerraVentusAlmighty King MickeyBut. I think we can be a jerk to Dehanort and have Lea, Roxas, Xion, Donald, and Goofy jump into the fight. Because friendship. Still in the fight. Not a Light. That can be done also

Here's my theory. http://kh13.com/forum/topic/47407-kingdom-hearts-3-scenario-theory-ddd-spoilers/?do=findComment&comment=964725 Fair warning, it's kinda long.
