@Background Pony #2ACF
Going Matpat in word form doesn’t help at all. Make a visual representation of a timeline without the minute details. I’m more interested in the timeline itself and not much the why.
I don’t think the timeline is realistic as long as the mess persists. Hasbro has made a mistake, they don’t have an overview manager who could coordinate the work between the G5 movie, TYT, MYM and the IDW comics, and much less the writers, because it seems in C2 that these worked separately and with little coordination. Too many logical short-circuits and insufficient plots with large gaps that even a child could detect. Moreover, it has been discovered that the writers - especially in the MYM team - only “cherry-picked” what is found in established lore from the G4. The IDW writers with the clear exception of the last one from G5 #5 which is the most lore-breaking that has been seen in a long time, have been more faithful to the G4 lore.
Equestria’s collapse is possibly referred to the IDW comics. So I think the matter surrounding the Unity Crystals is the matter for the MYM.
Opaline is no ordinary alicorn. She noted herself as one of several alicorns, as a “fire alicorn”. By looking at how big she is, it’s easy to see that she’s in “Luna mode”, which is not unattainable for unusually large regular ponies, this was seen in G4. And her size was no less when she appears in the G5 #2. She is only a head taller than Misty and that seemed to be the case against Fluttershy. Logically, that means she was an alicorn even back then. She called herself a unicorn, but that could be in disguise. Discord didn’t explain what happened since the ponykind split up, but it’s possible that it wasn’t just the unstable emotional magic that was the threat.
This gives room to insert the MYM stories from E2 and E6. Opaline’s introduction to the ponies was knowingly omitted, only that she had come into conflict with Twilight and lost her magic as a result. As a result of the conflict, the Unity Crystals arose, as Twilight gathered all magic - or more precisely the ability to use active magic - to prevent unstable magic from threatening the Ponykind and the rest of the world. In MYM it was seen that the magic is too dangerous.
Opaline’s choice of tactics in MYM suggests that she preferred to operate in secret to create the right circumstances for divide and rule, and even then she may have a following of loyalists not seen in MYM so far. In a MYM episode it was noted that when Sunny was an alicorn, the ponies instinctively reacted to her. So she can in post-S10 of G4 start an actual civil war between the conservative forces discovered with Neighsay in S8, and the liberal forces that support Twilight’s opening of Equestria. Maybe what Discord said; “then truly terrible things happened”.
In the end the Mane 6 won, and for this they needed the Unity Crystals to stop Opaline, possibly because they realized she was going to do something very fatal to all of them. From E2, a broken sentence suggests that Opaline would “open” something, which Twilight feared and thus wanted to communicate this to the Mane 5.
Is the information about the alicorn civilization from the royal sisters’ diary still valid? Because the clues point to a possible background around Opaline.
