Trailblazing. That would be an interesting cutie mark, right? Scootaloo, Sweetie Belle and Applebloom thought so! And what better place than in the Everfree Forest?
Little did they know though, that within the dark forest is a gateway. A gateway to a world so unlike their own and so terrifying, that nary a soul will speak its name. Nor the name of those who reside within... Ancient forces of primeval and infinite power within their domain.
They have been watching for generations. Unbeknownst to the citizens of Equus. Never seen... but always watching. Always meddling.

Set in the universe of Storms of Change though, reading the prior is not required.
