Equestria has been through a number of changes during the years that Princess Twilight Sparkle has ruled. Over the course of her rule, she's had to come to terms with many things. However, one item she has an issue with consistently shows itself to her and wasn't even decided on by her. She remembers witnessing it, but nothing about it sits well with her as others tend to.
Story is a one-shot I've wanted to write while working on my previous work. The idea didn't work there, but was strong enough to write about it on its own.
