Despite the maps in Genealogy being gigantic, the territories of nations seem tiny, especially in maps where castles are relatively closely placed together. But Jugdral in general is supposed to be a The Dung Ages look on Fire Emblem. Territories really were relatively small compared to today's world; nation-building hasn't taken place yet! At least, at the start of the game.... However, since single turns are usually impled to take at least an entire day in-universe, it's also very likely that tropes like Units Not to Scale and Space Compression are at play when it comes to the maps. It's the only way you could meaningfully fit an entire nation, or most of it, into a single chapter and still make it playable.
The Nattsu Fujimori manga's interpretation of the Silence staff is that if the victim tries to cast magic, he can only shout random words. That makes sense, since using the Silence staff on bosses doesn't stop them from talking.
It also makes sense when compared with the Oosawa manga, where Deirdre uses Silence on Clement and completely renders him mute. The Fujimori manga is Lighter and Softer and plays lots of Jugdralian tropes for laughs, so it can get away with a more random interpretation; the Oosawa manga, on the other hand, is Darker and Edgier and plays these same tropes for massive drama, so it chooses a more literal depiction.
The first Holy War was actually only about a hundred years ago. This would explain why the Loptr Church survived the years after the war (wasn't too long for them to die off), why some characters (Scipio) don't have Holy Blood despite being nobility, and why the power of the Crusader Weapons faded in later games (they weren't meant to last, and only still work in the game because they're not that old).
Selfina says that Finn was always cold to women, even his own wife. In-game, Finn has three predestined pairings (Lachesis, Adean, and Ayra), but he never talks to them. He is the only first generation male who never gets a conversation with a girl. He only gets predestined pairings because he can talk to his daughters.
The King of Northern Thracia and the Queen of Miletos are married. Their names are Blume and Hilda. Blume can also be translated as Broom. Together, they make up the name Broomhilda, Brynhildr, or Brumhilde.
Brigid and Edain are amongst the small few that survive the entire game, it can't be a concidence that both of them have the highest luck growth of Sigurd's army.
Also in gen 2 both of them become a mother figure to Leif and Seliph respectively.
Prince Kurth's assassination makes sense from more than just a tactical standpoint. Not only does it make it easier for Arvis to take the throne once he marries Deirdre, but if Kurth were to live, he'd be able to reveal that the mother of his child is Arvis's mother, which would ruin Manfroy's plan.
Even in The Dung Ages setting of this game, incest is still highly taboo. That being said, you can do it too, but as some conversations imply, many pairings don't end with marriage or are the result of someone being cheated on.
It might seem a bit strange at first that enemies in the second generation use fire and thunder magic almost exclusively, since wind magic is objectively better in this game. However, this actually makes sense; wind magic is the signature weapon type of Silesse, while fire and thunder magic are the signature weapons of Velthomer and Freege, respectively. Since Velthomer and Freege are territories of Grannvale, which is, of course, the main enemy in the second generation. Of course the Grannvalian army would be getting their weapons from there instead of Silesse! This is further supported by the fact that Musar (a boss in chapter 9, and the only enemy character in the second generation to use wind magic) has minor Sety holy blood, and therefore must've been born in Silesse.
How come Seliph is specialized in killing mages? Given how the cult has taken over Jugdral, he figures the best way to solve the problem is to focus on those responsible for the misery of everyone.
It's important to note that amongst the Legendary Weapon users, Seliph and Ares are essentially Paladins with Swords as their preferred weapon. Gae Bolg and Gugnir are wielded by Dragon Riders, while the Helswath is a thrown Axe. It makes tons of sense that the only close range weapons that are wielded by non-airborne units are given the strongest anti magical capabilities.
Despite Eldigan being accused of being Lawful Stupid by the fanbase due to his actions of saving and supporting the likes of Chagall until the very end despite everything he did, his situation at the beginning of Chapter 3 is a perilous one and it's no wonder he feels trapped no matter what he does. While Sigurd invading Agustria saved Eldigan and Lachesis' life, his actions turned the nation into a dependent state at the mercy of Granbell, with the corrupt governors recently appointed essentially replacing the corrupt Agustrian nobles he killed. While Eldigan could have replaced Chagall as king, doing so would not only tarnish his reputation by becoming an The Usruper no different from him, it was inevitable that he would fight and rebel against Grannvale, seeing as how Sigurd could not convince sway his superiors in granting Agustria freedom due to Reptor and Lombard essentially controlling the kingdom by then.
Chapter 2 is chock-full of this.
It's clear from the get-go that the Agustrian nobles don't respect the throne one bit, considering how Elliot blatantly ignores a peace treaty for the sake of personal glory. Boldor of Heirhein is the only one who follows Chagall's order to attack, because he sees it as a mutually beneficial action – it's his opportunity to get even with Eldigan after he humiliated Elliot. It looks like he's obeying, but Boldor's really just doing this for himself.
Philip, the Heirhein general in Chapter 2, orders his men to form a defensive line after Elliot's cavalry squad have rushed off to attack Nordion. This doesn't make sense from a story standpoint – Heirhein doesn't know that Grannvale is going to be involved in the civil war, so why would Heirhein defend its castle if it's fighting against Nordion, whose military might at the time is essentially three Cross Knights? The Suzuki novelization offers an answer: Philip found it improper for the Agustrian lords to infight, but couldn't speak out against his own lord. Instead, he ordered his men to remain put to avoid escalating the senseless battle that Elliot was waging.
Macbeth of Anphony has a relatively small army compared to Heirhein and Mackily, and the vast majority of his soldiers are hired mercenaries from Voltz's corps. The ratio of mercenaries to soldiers is a sign of both the Anphony people's dissatisfaction with Macbeth's rule (less people want to support him and join his army) and Macbeth's lavish lifestyle (as he's been exploiting the villages for wealth, he has a lot of money to throw around and can afford to buy an entire army of mercenaries)
The loyal and honorable Eldigan, Zane, and Philip are staunchly different from corrupt nobles like Boldor and Macbeth. Agustria's title is "land of the knights", so it's natural that there'd be a few patriotic and genuinely good folks in this corrupt moshpit of a country.
The very size of the maps is the first hint that the game is going to be a deconstruction of the standard Fire Emblem format of "conquer everywhere you go until you save the day." In the other games, you would take (e.g.) Agustria piecemeal over several chapters. But by zooming out, the player can see that they truly are conquering, and later liberating, entire nations.
Most of the names in this game are taken from the mythology and history of northern Europe, especially from Nordic and Celtic myth. The Thracian peninsula, in contrast, does not. Thracia itself straddled the Black and Aegean seas. Character names include Hannibal, Judah, and Muhammad, all historical figures from Mediterranean and the near East rather than the north—further highlighting the divide between Thracia and the rest of Jugdral.
In the final chapter, none of the castles are guarded by their liege-lord. Hilda, Brian, and the lord of Edda are all deployed in the field, while their castles are in the hands of Lopt priests—a subtle highlight of how Grannvale is now completely under Loptous' control.
There's quite the speculation about Anguilla from the Twelve Deadlords actually being a forcibly revived Tailtiu (or her little sister Ethnia, if Tailtiu was left unmarried). The lead hints are them having the same class (Tailtiu can promote into Mage Fighter, Anguilla already is one, nothing is said about Ethnia's supposed class but she probably was a Mage Fighter too), both having minor Thrud blood, andAnguilla possessing a Thoron spellbook, just like Tailtiu did when recruited. Sure, it's just speculation at the moment, but if it is true... then HOT DAMN.
In fact, going even deeper into this, what's to say all TWELVE of the Deadlords aren't the same?! Julius is not above using puppets of the past, so it could be that the player is facing the likes of Arden or Jamke or Deirdre since their all dead. Really the only one who wouldn't count would be Gallus, the Dark Bishop.
Holy Blood and abilities are taken into consideration, which was why only Tailtiu enters the possible speculation, with her only missing the Pursuit skill. Mus is a Baron and has affinity with magic AND Adept AND Pursuit, all of which Arden lacked (you can give him Pursuit with Pursuit Ring, but he misses out on other aspects). Canis did not have any Holy Blood and Nihil unlike Deirdre, who in turn did not have Pursuit and Critical. Though scarily... Jamke as Draco might look very likely, as they were probably very spot-on... even moreso than Tailtiu as Anguilla.
That last one is a bit less likely, since Thracia 776 confirms that Brigid/Eyvel becomes Draco if she isn't recruited or she dies in that game. Of course, if she doesn't, then it's entirely possible that it's really Jamke.
The Oosawa manga raises some fridge horror regarding the replacement children characters. The only way you can get them is if the mothers of the regular children go unmarried, therefore they (the regular children) don't exist in part 2. The reverse isn't necessarily true, however. Only two pairs of siblings have at least one established parent (Amid and Linda for Ethnia and Tristan and Jeanne for Eve), and even they could still theoretically exist even if the regular children are born. The question is, why are they never seen at any point? The worst part is, Larcei and Lana flat out state that they've lost friends to the Empire. Granted, this fridge horror might be lessened by the fact that some of them were supposed to appear in Thracia 776, but not by much.
Remember the Battle of Belhalla? How tragic that was? Yeah, we can make it even worse. Since Azelle was in Sigurd's army, that means Arvis almost certainlykilled his own half-brother.
If Manfroy hadn't manipulated Arvis into killing Sigurd, Julia would've never been born. Think about that: for Seliph to meet his friend/potential love interest/half-sister, his father had to die.
