* AdaptationDisplacement: Not the game itself, but the final boss theme [[https://www.youtube.com/watch?v=-q5Y7qc3sHE Sublime Domain]] is possibly more well-known for featuring as the final boss theme in a [[VideoGame/TheLastPromise certain]] ''VideoGame/FireEmblemTheBlazingBlade'' [[GameMod ROM hack]]. In fact, it's more common to see people quoting ''it'' than the game it came from on videos of the song.
* {{Fanon}}: Due to Rosea's uncanny resemblance to Hrist Valkyrie of all people, it's a fairly common fan theory that Rosea ''is'' Hrist, living as a mortal while Lenneth acts as the Valkyrie.
* FriendlyFandoms: With that of the Fire Emblem ROM hack ''VideoGame/TheLastPromise'', mostly for its use of the final boss theme Sublime Domain for its own final boss.
* SugarWiki/FunnyMoments: ''Anything'' in the Seraphic Gate. The SillinessSwitch in this game is taken up to eleven here; with characters frequently engaging in playful skits making fun of the fact that they're in a game, obscurely powerful hamsters, and loads of mythology gags such as how Hrist is complaining about not getting her own game.
* GameBreaker: Veigr's Warcry. Be it intentional or a bug[[note]]Plume skills run off Wyl's Magic stat, so it's likely it runs off the attacker's as well[[/note]], its effect[[note]]adds roughly a 5% chance of instant death to all ally attacks for three turns[[/note]] ''always'' activates when a mage attacks, provided the enemy isn't a boss or undead, as they're immune to it. It's a Plume skill, so you need sacrifice the right person before Wyl is able to use it, but using it with a team of magi is the closest thing you'll get to using the Destiny Plume.
* GoodBadBugs:
** Union Plumes revive fallen allies in front of the user, so long as there's an open space there. This includes space that are way too high to get to without spending several turns getting there normally.
** Reflect Sorcery stops magic from dealing any damage (but doesn't actually reflect it), yet it doesn't stop the instant death effect from Veigr's Warcry. However, since technically no damage was dealt, the enemy killed by it dies with a full health bar.
** Dash completely ignores terrain effects, which allow anyone that uses it to move three spaces, regardless of whether or not they would be able to do that normally.
* PlayerPunch:
** Any time you sacrifice a character to the Destiny Plume, this is followed by a sad death cutscene. And sometimes, they even ''know'' Wyl had something to do with it. What makes this even ''worse'' is knowing ''you'' did this to them - this is ''completely'' different than when Lenneth was asked to do so to Lyseria or Gandar where Lyseria [[ICannotSelfTerminate flat out asked Lenneth to kill her]] or where Gandar [[RedemptionEqualsDeath was given a chance to redeem himself]].
** The last battle of Path C: [[spoiler: every friend you sacrificed to the Plume is now an einherjar fighting on Valkyrie's side against you.]] And this can become flat out VideoGameCrueltyPotential depending on who you sacrificed. You can literally [[spoiler: force people to fight their partners... or even their own family members]].
* SelfImposedChallenge: Beating the A route on a first playthrough is possible, but is also incredibly difficult due to how all campaigns are one-time events, preventing any sort of grinding. This means if the player makes too many mistakes, such as wasting money, leveling the wrong people, or failing overkill quotas, they could doom their run. On the other hand, it can be satisfying to beat such a hard route without NewGamePlus and not rely on the sinful rewards of previous playthroughs.
* TearJerker:
** When you consider that [[spoiler: on the path where you recruit the Bloody Twins, Natalia was killed by her own children without even a second glance...]]
** Also, any death scene after you use the Plume counts. Expecially since it was YOU who decided to sacrifice them...
* ThatOneLevel: Early enough in the game, when you'll have done at most only one sidequest, if you chose the Rebel path, you get the mission to save Natalia. Who is already on the guillotine, which can't be reached without walking all the way around the map and past the level's boss, has puny attack, and is constantly attacked by a soldier who is supported by a mage ready to heal him and finish off Natalia. The boss can... no, WILL kill any of your units in one hit (expecially if it is your first playthrough), and thanks to the CombinationAttack and his mook's wide range, can obliterate your whole party in one turn if you get too close to him.
* TheWoobie: [[spoiler:Rosea. She wanders from city to city in a demon-infested world to heal those in need. Because of her good deeds, the citizenry goes as far as to call her a "Saintess." Even though they grant her this title, [[StepfordSmiler she hides behind a mask]] to hide her past reputation with the magic court and her hatred for Lieselotte. What's worse, she's not only a victim of Lieselotte's manipulations, but Fauxnel's, as well.]]
** Even worse, [[spoiler:you only get her in the C path, which is the worst path in the game. Unless you choose Natalia/Earnest in Chapter 2, she is surrounded by the most unsavory, broken, unsympathetic people in the entire game. The only exception is Duwain. She is then forced to spend much of Chapter 5 traveling with a Prince that she clearly dislikes and considers "unforgiveable", but can't do anything about. In the end, she is forced to fight the Valkyrie alongside Wyl, who is responsible for her allies being killed by the Plume, in what looks to be the same place Lieselotte is killed. If she isn't rotting in Nifelheim, then unless she flees Artolia, she will be stuck in a war-ravaged country ruined by infighting. The cherry on all this is that Fauxnel is the archmagus, and if she found out the truth, doing anything to him would accomplish nothing. Much of this is actually optional, like shattering her by pluming Duwain in front of her, but the game makes it VERY easy for players to make her life a living hell. In fact, Rosea ends badly no matter what she does.]] The most merciful thing to do might be to [[MercyKill plume her]]. That way, at least she [[spoiler:gets to live on as Lenneth's einherjar.]]
