Ok so I’ve been thinking this through, and I’d have to say kinda. In the new movie, A New Generation, Izzy lives in a forest with a ton of crystals. So I was thinking, Mabey the Empire fell from an unknown villain. The villain stole the crystal heart, and the kingdom went into chaos. Then it was abandoned and destroyed. Then, after the spilt of the species of ponies, the Unicorns went to live there, but they became sad because the crystal heart was gone and it was the only thing that would make that place happy again. By the way, this probably happens a long time in the future from g4. Anyone else have an idea of where it went?
