Behold. These lifeless keys used to be full of power—united with the hearts of their masters. On this barren soil, Keyblades of light and darkness were locked in combat... as a great Keyblade War raged. Countless Keyblade wielders gave up their lives, all in search of one, ultimate key. And it will soon belong to me... χ-blade.

Admirably done. I knew this was a journey you could make—over the unseen wall that divides darkness and light. And I was not wrong, Terra!

Why, I did him a favor and freed the darkness inside him. Alas, poor Ventus never had the fortitude for such strenuous trials.

Go take what Ventus owes you. And take Aqua's life.

You see how powerless you are to save them? Savor that rage and despair. Let it empower you!

Yes, boy, that's it! More! Let your whole heart blacken with anger!

There, you see? The χ-blade has been forged! And now, Terra, it is time for the final union!

At last, our moment is here. Out with the old and brittle vessel, and in with a younger, stronger new one! I swore I would survive... and be there to see what awaited beyond the Keyblade War! And now it is your darkness that shall be the ark that sustains me!

Darkness rules your heart—it gives me control. Muscle and sinew that once obeyed you now rebels against you. How you can remain here at all confounds the mind.

Hmph. Don't even entertain any notions of escaping me, boy. In the end, your heart will be engulfed by mine forever.

As I recall, you couldn't even handle your own darkness. How, then, will you triumph over mine?

Oh? So that's how it is, is it? Someone else has set foot in your heart. Eraqus, you sly fox...

Brave words, to be sure. But I'm a patient man. We can take as much time as we need to settle this little property dispute. However, know this— You are just one of many roads that I might choose to take. Trust me. I made certain of that.
