Sweetie Belle woke up one day, time had moved on without her.
There was nothing left, Equestria was reduced to nothing but ruins and snow, somewhere she used to know so well had been reduced to nothing but memories of war, fading away in a sea of white.

Echoes of the past guided her, events she had never seen with her own eyes had replayed before her, making her retrace their steps to find out what truly happened.

She thought this was a dream, something with meaning. Though meaning was once lost once the steel shell underneath was revealed. Nothing made sense to her, not anymore.
She would never be able to understand a past she had never been a part of.
