This story is a sequel to It's a Dangerous Business, Going Out Your Door
An ancient evil has awakened. No, really, it has. From the depths of time, a black, noxious threat has risen up after millennia of imprisonment. It washes like oil over Equestria, swallowing up towns and uncovering terrible secrets long buried. Twilight Sparkle, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy and Rarity are prepared to combat this great darkness. However, to do so, they must uncover the truths about the Elements of Harmony, and the truths about the ancient forerunners of Equestrian culture. What they find will challenge their conceptions of their own places in history and ponydom's place in the world. The six Bearers of the Elements must draw upon their friendship and the strength of their hearts to stand firm against the darkness. If they fail, it will mean the end of everything.
