My Little Pony: A new kind of Friendship

Deep within the Everfree forest sits a castle in ruins. The castle once belonged to two sisters, but it now becomes a source of reference to a young Alicorn princess named Twilight Sparkle. She and her friends AppleJack, Rainbow Dash, Rarity, Pinkie Pie and Spike all used the castle and its inspiring contents. They brightened the ruin, unaware it was home to somepony new.
