So from what I can tell based on two Webm uploads, “Frosty Shivers”, aside from being an incantation to delete expended energy from the universe, is also the unicorns’ name for Winter. Subsequently, they feel compelled to chant it whenever it snows.
Furthermore, this suggests they didn’t even have fire.
As with this book in C3, the page with the three “guardians” has two symbols, one about fire - the other about ice. What that means is not understood. We only know from the book itself which is confusing, that there are three specific topics; firstly, that the “guardians” who can symbolize the three tribes, had begun to forget, secondly, the two symbols of fire versus ice - the unicorn with ice and the earth pony with fire. And third is that the tribes were gathered at a time when Twilight Sparkle was absent.
The book revealed at least that the Crystal Empire may still exist in G5, and the three mysterious unicorns on the cover are not explained, and that Zephyr Heights was possibly not a pegasi city to begin with, the headdress that Pipp wears is seen on a unicorn.
We now know for sure that the Winter Wishday is more the ponies’ form of the Thankgiving Day than the Christmas, even if the Christmas traditions are included in the celebrations. Just hope that TYT has something special at Christmas time.
The new game “Mane Merge” is now out, and this shows that Opaline is much stronger than expected. Her evil roots that she created in Bridlewood spread to the mountain that Zephyr Heights rests on and Maretime Bay in the coast tens of miles away. This is reminiscent of the roots of Everfree that went berserk at the beginning of the S9, so it’s a G4 reference. As Opaline obviously uses corrupt magic, it creates two facts; first, that the magic in Everfree was evil and corrupt, and second, that Opaline herself is corrupt. But the lack of signs of magical corruption on Opaline then suggests that she is “still” in a pre-corrupted state.
We see the alicorn magic for the first time in G5, these Sunny did unwillingly early in TYT do not count. And considering the revelations about Opaline’s secret abilities - the earth is sure to shake when the alicorns’ true strength is revealed to the ponies. For Sunny not only has her alicorn powers, she has the Unity Crystals - and most importantly, her friends with these cutie marks that make it possible to help her out. Friendship will save the world.
