As you may have guessed, this is a design for a Keyblade (from Kingdom Hearts) from a world that doesn't actually belong to Disney.
The contest is this: The first person who can correctly tell me the land this Keyblade hails from wins a request. Either a piece of art or a short story, (as always, the cap is PG).
There is absolutely no time limit on this contest. If this has been on my page for a year (or so) and no one has said the right answer, feel free to speak up.
I will honor it.
