Sunset hasn't received a message from Princess Twilight in a week. When she finally receives one, it's not from Princess Twilight. When she reads it, she finds that it's from her past self.
Knowing this, Sunset sets out on a course to make her past self realize that the mirror was false. That being an alicorn wasn't their destiny. She needed to make her past self understand. Otherwise, everything could go wrong. She doesn't care about the consequences.
However, the ramifications of her somehow being able to talk to her past self is something even worse than she expected...
This is an alternate universe, set in within one of the time altered universes that Starlight created.
