Neither Celestia nor Luna can determine how they're home got shrunk, nor what led Golden Gavel to agree that the castle and everyone inside would be put up for auction.

The Princesses are struggling to understand the drive behind the bidders outside. There's no way anypony would put in such high bids for ordinary snowglobes, so they'd have to know it's the real castle they're bidding for, but several of the ponies are not anypony they'd peg as being inclined to seek ownership of royalty.

Who'll make the final bid? Do they know about the Princesses' predicament? Will they try to help, or would they prefer to keep these two most prominent alicorns for themselves?
