When Princess Twilight Sparkle decides that a get away is in order for the six friends, they naturally jump on the idea. Encouraged by Princess Celestia, Twilight takes her friends to a distant location at the guidance of her mentor. However, the ponies find themselves on a path that is not the one the Princess had intended them to travel, and end up in a land that is much older and out of reach than any of them could have expected.
A primeval world populated by creatures not seen since ages long buried beneath the rock that makes the very skin of the world, the ponies must learn about this place, and most importantly, find their way back out. Soon they learn that while their modern Equestria has its share of villains, the ancient world sees no such thing as good or evil. Instead, the ancient world only knows 'survive'.
Their travels in this unseen land bring them new friends, and new dangers that they would have never expected to encounter, even in a land as full of mystery and variety as Equestria. This is the telling of the Six, and their travels through The Oldest Land.
