I'm sorry for worrying everybody. Please ignore what I've said lately but I've forgotten something very important... something that I'll never forget again.
I spoke with Aros (or rather, fought him) and remembered something important: the heart is more than a source of loneliness and despair. It is a source of love and happiness. I am horrible for forgetting this but now I'll always remember.
Everyone, this the weapon we can use to defeat the Heartless. This is how we can stop them: with out hearts. It is our light and it is the most powerful resource we have.
I hope no one forgets that like I did.
And don't worry Xeryim... Aros... the Septsinian or whatever... even your King... we'll all win and we'll win with our hearts.
