6 years had passed after what was called: The Canterlot Outbreak. Those who survived had been coping well after the horrors they had endured. But for a small few, there were two in particular who were never able to move on. There had been stories about what happened in Canterlot, and how the entire city was completely, and literally wiped off the map. There had also been tons of charities to help provide compensation to the survivors of the nightmare, such as the Dazzlings performing concerts to raise money. But one day, when Sunset Shimmer and her friends receive a visit from Vinyl and Octavia, she tells them about a journal she found in the bowels of the lab she, Twilight, Sunset and Applejack visited. What they discovered in that journal was horrifying, but it has also given them a new and deep motivation.
