The independent nation of Pinery is just that: Independent. Separate. Self-sufficient. Princess Celestia respects this, which is why when their head chef disappears without a trace, she sends three bright young members of her royal guard to settle some nerves.

On paper, the team makes a lot of sense: Captain Minerva the Brave, a stalwart pegasus with enough brawn to make up for her brains; Lieutenant Terrain, a cunning earth pony with enough brains to make up for his brawn; and Foghorn, who is determined not to screw it up for the other two.

Together, these three friends embark on a polite and respectful security mission to Castle Pinery. Together, they'll discover that just because it’s hard to keep secrets behind wooden walls, that doesn’t mean they aren’t there to be found.
