Princess Celestia: Wizards throughout the ages have pursued the secret to ponies' true inner power. Star Swirl the Bearded perhaps got the closest, but even he didn't understand how tightly magic and friendship are intertwined. That our greatest strength comes from all of us working together, helping each other.
Twilight Sparkle: Really? You'd think "the power of friendship" would've been the first thing they tried.
Princess Celestia: Many scholars searched within, yes, but only alone. Through meditation and such. They weren't keen on sharing the power if they found it.
Twilight Sparkle: So... I'm here because I worked with my friends? Shouldn't they be here too?
Rainbow Dash: Nah, I'm good.
Twilight Sparkle: And, like... I *just* discovered this. I don't think I've mastered it yet or anything...
Princess Celestia: What you've discovered, and everything you will learn from here on out... will fundamentally alter Equestria's future. *That* is why you are here.
Twilight Sparkle: Wait, did YOU know this was going to happen? Like, all along?
Princess Celestia: Before I answer that, let me ask you: What do you think of the concept of "destiny"?
Twilight Sparkle: ...Geez. Clearly we're not on the Elemental Plane of Softball Questions...
I'm right there with you. Past a certain point in the timeline, there's an incredible temptation to have Twilight knock her mentor down a peg. I blame Luna egging her on.
I'm pretty much always down for taking a mentor figure off of a pedestal. In part because people (or ponies) on pedestals tend to become rather one dimensional and boring. Luna's pretty much the most interesting of all the non-main cast because she exists in four dimensions due to how the whole Nightmare Moon thing keeps her past influencing her present. I actually wrote up a thing on Celestia that if I had any art skills at all I'd submit to Spud's guest strip section. Short version is that the transition from Action Hero-->banished her sister-->current ruler of Equestria is covering up some very rough years and the 'Golden Age' of the show is actually a relatively recent development. Which I guess would also help explain how the horseshoes came off so readily for the new series.
"Heavy plane", nice. Also, yes, it's a very peculiar habit of this version of Twilight. The whole "trying to poke logic holes at my trusted mentor's explanations" does have the benefit of making her act as an audience surrogate for everyone who MAY raise those questions when reading this, though.
Kinda unrelated, I've got a prompt for you readers: what are you more invested on, the "player group and player group dynamics" aspect of the comic? Or the interaction with the game's (and by extension the show's) narrative?
For seven years or so.
Then, in some indeterminate future time, Equestria will have fractured and the three pony tribes will have gone their separate ways.
The next series (G5) is set in the same setting as G4, but the promo material makes it pretty clear the setting went completely to hell so fast the main character still has merch with the cutie marks of the Mane Six.
Though it was enough time that they've gone from dragon-fire "email" through semaphore/heliograph, telegraph, land-line telephone, and into cell-phones (which implies they've developed semi-conductor technology, and some form of computer).
Semi-conductors were already present in G4, though not utilized much. There were several headset microphones, which can't really get small enough without printed circuit boards
The actual movie gives the impression that a lot of time has passed, to the point that that "merch" is more like archaeological reconstructions rather than contemporary merchandise.
Sometimes things fall apart. If they're worth remembering fondly they often get rebuilt eventually, but sometimes unseen weaknesses or external factors cause things to fall apart.
And it's not like Equestria didn't have a precedent of being largely segregated and surprisingly close to dividing along racial lines even when things seem fine. I hope Twilight tried to actively address that during her rule, but that sort of problem is not quick to fix.
Speaking of historical events, we know from the first Hearthwarming episode that ponies' racial magic works just fine without friendship. There was magic all over the place back when the tribes were literally at war with each other and their hatred was fueling an ice age. Friendship may be one source of magic, but it is not the only one.
Y'know, the G5 discussion got me thinking if the new movie is another DM-less oneshot session with one of the players being the DM for the other five. No idea who is who, but I certainly imagine the players discuss the whole race separation and magic going away just as intensely as the fandom.
I'd favor Rainbow Dash's player - a lot more self-aware, and deliberately playing her temporarily-GMPC as not so aware - as the GM for that, given the increased amount of adventure and worldbuilding.
Ohh! Applejack runs the new oneshot, because she's the one that doesn't really show up.
Rainbow Dash runs the atheletic flying pony
Fluttershy runs the sheriff that animals love
Twilight runs the optimistic hero
Pinkie play the unicorn hero
And Rarity plays the pompous singing star.
I dunno, I think it fits a roleplayer perfectly well. They don't really talk to Celestia much, so it makes sense there's less of a rapport... I actually kind of like that Twilight keeps her sarcastic edge in this story, a little bit. Maybe Celestia doesn't translate as well to a roleplaying game...?
Celestia is "important quest-giver" and "sets the story in motion for one character". As part of the Twilight character backstory, there was awe and reverence. The player was also new, I believe? So, she's just gotten more accustomed to the game, the setting, and the group. A group that has sass and strong-willed attitude in most of the players and characters. It was bound to rub off in one way or another, especially with the "guiding mentor figure" having been ambiguous in presence and impact. The most recent interaction before this was "ominous at best" with a tone of "if you succeed, you'll have done something I either never tried or failed to do". Elevation from "student" to "technically a peer" (even before the change about to happen) can bring a shift in tone... especially if the player has started getting tired of cryptic discussion
I like how she gets more "sassy" with Celestia. It clearly shows that their relationship is strong, and close, because Twilight feels safe goofing around with her. (At least, that's my take on it. 8^)
