The Pegasi eventually won the war, and slowly the Unicorns became endangered, most taking hiding. Because of these tragic events, the three types of ponies were isolated from contact with each other, and there was no trading. Not to mention, Celestial and Luna had lived their lives already, and Princess Candace was in a disastrous situation - she couldn't find any Alicorn that could assist her in controlling the night and day. Eventually, she came to the gloomy conclusion to just let time go by itself, like in. the Everfree Forest.

Fifty grim years passeed by, and a sage pony they call Kimono was simply given advice to a fellow pony, blissfully unaware of what she was destined to do...
