So there is definitely a lot of new out there in the G5 that has not yet been discovered.
I think, and I don’t want to take the wind out of your sails right now, but this statement of yours actually sums it up quite well. I mean, I love the way you think and also most of what you say seems relatively coherent to me. The only thing is that I actually (still) lack the knowledge about Season 10 to be able to answer here accordingly.
Well, the following points seems quite the canon timeline.
- Age of the Ancients (Grogar, Gusty the Great, Stars Swirl, Rise of the Two Sisters, Discord, Lord Tirek)
- Age of Equestria (Planting of the Tree of Harmony, Disappearance of the Pillars of Harmony, Nightmare Moon Incident, Celestia reigns for 1000+ moons)
- Age of Twilight (Twilight’s Ascent to the Throne, Creation of Unity Crystals, Breakup of the Three Tribes)
Am I miss anything?
Of course, this is only a very rough list. Very, very rough. But if you think about it, MLP G4 actually has quite an interesting lore. And certainly a lot of interesting species and locations. It’s just too bad that no one really takes the trouble to write everything down and tries to connect everything that is not retcon. That would be a rulebook that I would buy immediately. ;-)
I would happily make such a rulebook, but there will be too much speculation on my part. And it is true that we need an encyclopedia of the lore of MLP that all future authors and producers can use for future publications. Not least to avoid misery as the “harmony knights” in the S10 who took their damage from this, as a writer went far beyond his ability in drafting the plot.
We know very little about Age of the Ancients which is partly based on G1, and which stretched over several millennia, and partly about Age of Equestria which is probably around 1,500 years - and it’s just a guessing game about how long Age of Twilight lasts, probably 800 years as a minimum. From G4 it is clear that the period of time for the pony civilization that came into contact with other civilizations already probably in the beginning, is very long.
No one knows when the manipulation of magic that exists in the background started, or who was the first to use magic. But there are many indications that the first established magical civilization was the predecessor of the ponies in their lost homeland, not least because these are immersed in magic to a greater extent than the rest of the world. We only know that ponies lived in small flocks scattered around probably in northeastern Equestria and the neighboring continent that may have interconnected once in the past - and that was where they gradually but surely begin to form societies and then civilization.
Much of the knowledge about the Age of the Ancients was lost during the flight from the cold about 1,500 years ago. And it seems that only Sunny and her father have preserved the few intact G4 books that the IDW comics suggest. Twilight was not so lucky, which is why she constantly searches libraries in hopes of finding preserved historical documents. Discord’s chaos when he was king - and ironically united Equestria even more - did not make it better.
Perhaps the hypothesis that there is an older threat than Equestria is correct - just not what one thought. For all have a price, and when the windigos went on the attack, it may have been just as the ponies began to pay the price for their overuse of magic. What happened then has not been repaired, despite the fact that the Mane 6 may have done anyone they could.
The ponies - and in sight alicorns - were the most powerful magical people in all of Equus, and this has become the background for what is now happening in the G5, where the ponies had fallen into a dark age with the disappearance of magic.
The non-ponies will not attack the ponies when they were without magic, possibly because the mysterious alicorn will stand in the way - and there is a strong possibility that the alicorn magic is not so weakened. But now that the ponies have regained their magic, they will choose isolation from Equestria to keep the threat away.
