Twilight’s trip to Earth and friendship with the humans brings new friends and enemies to her peaceful world. With the specter of war hanging over them, Equestria will have to form an alliance like no other to fight the menace from the void.
When an accident leaves Twilight Sparkle seriously ill, Applejack, Rainbow Dash, and Rarity must undertake a perilous journey to find her a cure. What adventures await them beyond Equestria's borders?
In the future, we'll colonize the solar system, cure cancer, clone the human genome, and build trans-dimensional hoodies that can summon tiny talking horses from an alternate universe. It's pretty snazzy.
