I feel G5 isn’t really that good at worldbuilding. We only know 4 locations so far. And we only know the barest details of 3 of them. Maretime Bay is better, but that’s because it’s the main setting. Plus, everyone is acting like they’ve come together a lot longer than I would think they have. The first MYM special addresses this, but then it never comes up again, and the ponies seem to be strangely aware of stuff from the other tribes despite being separated for “many moons”.
G5’s lore biggest draw is finding out what the heck happened between G4 and G5. Except the only ones who seem to be interested in finding out is Zipp, and Opaline might know except, but we need to take whatever she says with a few grains of salt.
