>>37576373>the crystal empire>the crystal heartNot mentioned, but it's not a disaster. The location and its attached McGuffin just weren't relevant to the movie's plot. Here's hoping the Crystal Empire is, at the very least, mentioned in the show.
>the elements of HarmonyThey got blasted to pieces alongside the tree in the S9 premiere.
>the school of friendshipNo clue, but it might've gone the way of magic schools and the Wonderbolts and closed down once the magic was lost.
>everfree forestNobody needed to go there so they didn't. The Everfree Forest has always been one or two miles away from the base of the Canterhorn, far away enough that Sunny and Izzy never needed to cross it to reach Zephyr Heights (assuming it's where Canterlot once was).
>the mirror that connects to the human worldAgain, not relevant to the plot, why would it get mentioned?
>celestia, luna, cadance, twilight, flurry heartNo clue. G4 staff mentioned Twilight wouldn't outlive the rest of the Mane 6 but nothing similar was said for the other 4. They could be anywhere.
>discordAlso could be anywhere.
>the rest of the mane 6 + sunset and starlight>are they all fucking dead?Yes.
>tirek, chrysalis, and cozy glow stone prisonNot relevant to the plot.
>all other pony cities (canterlot, ponyville, manehatten, etc.)Some like Manehattan are proven to have survived up until the foundation of Zephyr Heights, Bridlewood and Maretime Bay, if the board in the abandoned station is anything to go by. Hopefully we see them soon.
>why the fuck did everyone have amnesia about the pastPonies have always been notoriously shit at record keeping. Everyone in G4 forgot about NMM even though it had only been 1000 years.
>who is raising the sun and moon?No clue.
>pegasi control weather, was there no weather at all?Pegasi CONTROL the weather, not create it. When they lost the ability to fly the weather probably just reverted back to its "wild" state.
>how do they get cutie marks if there isn't magic?There is some magic still left, but I agree it should've been explained better.
>why are they energetic and lively without magic? When tirek stole the magic from ponies, they all looked miserable and weakTirek drained every single bit of magic off of a pony, and if IIRC the original plan for his powers was that he could also steal life force in some manner. When Cozy Glow stole all the magic in the S8 finale everyone was pretty much in the same state as they are now in G5.
>is tartarus still in existence?No clue.
