Co-written with my good friend Ajac, who wondered where all those postcards were going. We're taking some creative liberties here, so be nice. Standard disclaimer applies.
The thing about somehow miraculously surviving an invasion of Shadow Heartless during the destruction of your world is that the human brain tends to rationalize the process after the fact. Everyone has their fears. For some, it's falling from a great height. For others, it's a predatory animal of some sort, say a panther, or a snake (or perhaps, a Heartless). But the root of these fears all stem from the same place – the fear of a confrontation with death. But that's all beside the point. The point is that the fear of death is really the fear of the unknown, and the not knowing is what causes a person to rationalize a terrifying experience.
For the remaining residents of the Destiny Islands, the Heartless invasion was passed off as a tropical storm, a hurricane, and nothing more. The strange morphing shadows some claimed to have seen were hallucinations brought out by fear. Indeed, the islands did appear to be smaller, but surely they had always been that size?
Two of the remaining residents lived with this explanation as best they could, not talking about what they had seen and refusing to point out the very obvious, very large gaps in the story, until the postcard arrived.
On one side was a picture of a large stone building, white in color with a belltower at the top. At the foot of the building rested a large square sunken into the ground, also of stone. High walls surrounded the square and on top of the walls there appeared to be a variety of shops and houses. In the left hand corner, written in bold yellow letters were the words "Welcome to Traverse Town!" On the other side was a message.
It was in a messily written script, as though the writer were in a great hurry, or if the writer were a four-year-old. But it was clear to the recipients that the writer in question was neither, for they recognized the handwriting immediately as that of their son, who never did manage to perfect his penmanship, once again losing to Riku in their never-ending competitions.
Dear Mom and Dad,
I awoke in the back alley of a new world today. At least, I was woken by a large yellow dog. It's a strange world, with cobblestone streets and seems to be caught in perpetual night (I learned the word "perpetual" from my new friend Leon). Wandering around town introduced me to several new friends, like Donald and Goofy, who are on a quest for their missing king. I have decided to help them, in hopes that in their search I will find Riku and Kairi. I also find myself in possession of a large key (that I now know to be called the Keyblade) that can open anything and doubles as a weapon. (According to legend, the Keybearer was a great hero of the worlds, who fought the Heartless. So I guess that makes me a hero now!) I used the Keyblade to open a treasure chest and found this postcard inside. And because reality as I know it has been turned upside-down (and because this town has a mailbox) I will send this card, no address, no stamp, to wherever you are (if you're anywhere at all). If you receive this, then know that I will return home. If not, please return to sender.
