It's been five years since her passing. Five years since 'the incident'. Ponies had grown to live without the constant showboating and ego-centric comments.

But not all had grown accustomed to the absence of the never-ending drive and eccentric personality.

But most of all, no pony had grown accustomed to living without their dear friend, lover, hero, sister. And it wasn’t likely anypony ever would, or could, get used to it.

A few things:
1. As stated in the long description, 5 years have officially passed since the show— this is technically an au— Scootaloo now being 15 years old. (I like to imagine the CMCs were 10 in the show proper)
2. The amazing cover art was done by SlayerBVC's
3. Obviously, there’ll be death. Mentions of said death. Ponies grieving for said death. But it doesn’t happen on screen and how it happened isn’t addressed outright.
