A young mare unknowingly escapes from her forgotten world, only to learn that she was a figment of another pony's imagination. That pony, Princess Luna, brings her into the real world to show that she does exist…but someone (or something) else is pulling at the strings who has its own malevolent agenda, and it is an entity that is not to be trifled with.

However, another pony whom no one expected will arrive, a pony who will change that mare's life forever…

This story takes place before the events of Wisp, but you don't need to read that to understand this story…though it may help you understand who exactly the villain is.
