Birth by Sleep The whole BBS in one small chunk

This is just an assumption I have on how the game will pan out in very general terms, so spoilers are here.




So onto the topic, The game starts off with you being one of the three apprentices, T, V or A, and you are introduced to the main players: you, the other apprentices including Varitus, your masters Eraqus and Xehanort and maybe a few other unknown characters of yet. After a few intro lessons your told that Master xehanort and his apprentice have left unexpectedly.
Your sent, under the guidance of Eraqus where he promotes you to Chaser and sends you to seek the two others in order to become Keyblade Masters. You visit many worlds, old and new, where by you uncover more about the Keyblade War and how each of the apprentices are changing through their journey. They are tempted by the darkness, where the Unversed feed on their negative and dark emotions.

Finally through determination, they are able to fend off the dark and find that the master and apprentice have ambitions to take over all the hearts in the universe through the power of Kingdom Hearts, thus becoming all-powerful. They return to their master to be told that to fight the new threat of Xehanort, they must don a powerful but costly armour. They accept, and journey to the Crossroads, here the fight that we all know from the seceret movie, begins.
From here they are able to stop Xehanort, but however Terra had to give into the darkness (such as Riku did) to defeat the threat. However, the cost of wearing the armour, condemed them to linger as lifeless beings where few would find them.

Now I know i'm not detailing alot about the Unversed, Xehanort or his apprentices actions, or the continuation in the KH universe, but it is just a big overview.
So, whats you thought? Have I got it right so far?
