If (hypothetically speaking) you were to write a Kingdom Hearts ponyfic, and you (in theory) decided that each of the mane cast plus Celestia and Luna all would get keyblades, what would you call them?
I like the idea of calling Celestia's Guarding Star, and a possibility for Applejack's would be Best Policy, but those are the only ideas I had.
And remember, this is all just a thought exercise.
