In the Papuan Highlands lurks an unforeseen force, never inspected by ponies or humans alike. A scientist goes missing, and Celestia sends the Elements of Harmony to find her, but first they need a pilot -- one who has been there before. Follow Twilight Sparkle, Applejack, Rarity, Pinkie Pie, Fluttershy, and Rainbow Dash, as they face the jungle with its bizarre dangers, wacky peoples, multiple languages, tropical diseases, and incredible secrets; not knowing if the Elements are still with them after almost ten years of living in the human world.

Loosely a Conversion Bureau story, nonetheless, it's a good setting for a PoE story such as this.
