Interesting images about the upcoming series, which had come along with a number of different revelations about future G5 publications - so the mysterious alicorn is called Opaline, and her student or minion could be Misty. She was sent to Maretime Bay to spy on the Mane 5 and possibly sabotage them, it’s very interesting that my impression of her horn from the time I saw it was not wrong. For the horn design is not the same as on the other unicorns, Izzy has a smooth and pointed horn compared to the horn on Misty which is a bit angular and blunt - and doesn’t seem to radiate magic in the same way. She is definitely not from the same group/tribe as the Bridlewood unicorns. And both she and her “master”, the alicorn, appeared to be wearing multicolored fur in contrast to the other G5 ponies. It could mean that they both have a common origin.
And this origin was a little earlier revealed to lie in “the dark castle” shown on a map intended for children, still inspired by the European guidebooks from the 1960-1980 period with drawings of attractions as buildings on a map. But the G5 team, who haven’t yet got the right color set for the alicorn, keep messing it up, Equestria doesn’t have a south coast so the compass on the map is very wrong. The first map from the movie was correct, because the compass was correct in relation to older G4 maps. If the map had been upgraded with this after the end of the movie, we would have a good logical starting point for comparison with older G4 maps.
Then the G5 team came up with the revelation that the lone tree in the meadows between Bridlewood and Zephyr Heights was the Harmony tree, and an orientation point was established. Until then I was under the belief that the Mane 5 had bypassed the valley en route to Bridlewood, but the information of the G5 team showed that they had gone down into the valley and across the landscape where the two sisters’ castle once stood. Before the movie, it was revealed by the Hasbro that Zephyr Heights was in the same location as Canterlot, and the G5 team has made admissions that they had wanted to show the ruins, but did not have time for the extra work. The IDW took on the responsibility of showing the ruins to the fans, although with the exception of the cover of #2 they have not revealed where Canterlot was in relation to Zephyr Heights.
Unfortunately, the G5 team chose to reuse the childish map Sunny had made, from the movie. The dark castle through the use of the G4 map is located southwest of Maretime Bay. We know from the first map that a place associated with apples and farming is located there, probably the territory of Dodge City/Appleloosa. It could be where the apple clan had settled down after Equestria’s collapse, where it is possibly a neighboring state that has close connections with the state where Maretime Bay is located. However, the new map shows that the dark castle that the illustration shows on the edge of a cliff may be deeper inland from the coast. The G4 maps show that the land south of the Macintosh hills is divided into two landscapes, the Badlands - and the Mysterious South.
A map from the IDW G4 #2 has shown that the landscape beginning with the Appaloosan Mountains contained a number of mysterious locales, hence the nickname “the Mysterious South”. To the southwest after this we find South Equestria with Egyptian culture and to the southeast we find the Badlands with many dangerous monsters there and the jungle lands with Mayan culture. It seems that there were several canyons through the Mysterious South that were used to get from north to south without entering the hinterland.
From a historical perspective after the comics and the shows, it is clear that there were pony settlements in South Equestria long before Equestria came into existence, and that the ponies had come there from the northeast, presumably through the Mysterious South which may have been populated by pony tribes that left there from the old homeland that lay far to the northeast. Middle Equestria was completely deserted, until the three pony tribes were forced there by the great cold. We know that there are isolated pony tribes in the jungle lands and that the ponies in South Equestria, called Anugypt according to the IDW comics, were there several millennia before Equestria arose. It is possible that there were very old pony cultures in the Mysterious South in ancient times, which fell into oblivion after the rise of modern Equestria.
Opaline, if that is the name of the alicorn, may have her own kingdom there in the Mysterious South, possibly accessible by roads that cross the Macintosh hills and the Appaloosan Mountains. The illustration of the dark castle may suggest a mountainous landscape. Opaline is going to be Sunny’s rival as with Trixie and Twilight in G4, and if she has a kingdom and minions - she can challenge an upcoming alicorn by attacking her ideals.
It has never been established where Mistmane’s “Eastern village” is located on the G4 map. But the village is located in a mountainous landscape with a warmer climate than in Ponyville. Mistmane has multicolored fur just like Opaline and Misty.
This could mean that the two villains in G5 are from the same tribe as Mistmane, the horn on Opaline is no different from that found on the “eastern unicorns” who had never been given an explanation of their origin, only that they were not among the three original tribes of the middle Equestria. It is possible that these, like the Kirins, were a colony that had been established far from their home regions. We know that the kirins, who also pretended to have East Asian culture like the eastern unicorns, live in the peak of peril in the savanna lands between the jungle lands and the Bone Dry Desert. The eastern unicorns and the kirins may have had a history in earlier times, and we know that the hippogriffs had Chinese-style ships of the junk type. Which suggests that East Asian culture has a strong influence in the southeastern part of the continent of Equestria.
The ancient Chinese in our world were not much concerned with the sea, as they lived quite deep inland, so it fits well that the eastern unicorns should stay in the Mysterious South where Opaline may have her castle and possibly her kingdom.
