Fire Emblem/WMG

• Fire Emblem Tellius

"Chris" is Ike, and Soren is "Mark".

Chris is rather similar to Ike(though moreso to FE9 Ike), and we never see Mark's face. Soren and Ike left Tellius, got split up, and now Ike is helping people out because that's just how he is, while Soren is partly trying to make himself a rep so he can get better answers from nobles and the like about Ike's whereabouts, partly repaying Lyn for saving his life. Would also explain why the Tactician/Mark doesn't do any more tactics after becoming known. As for the supposed sinking/flooding Yune/Ashunera caused, I think it's more likely it simply raised water levels around Tellius(since Ike seems to head for other continents at the end). This theory would put Tellius and Elibe in the same universe as Akaneia, Jugdral and Valencia. And I kind of already believe Magvel and Elibe to be part of the same universe.

Lalum is Oujay's sister.

In his support conversation with Wendy, Oujay mentions that he had a sister but, because of how poor his village was, female children were usually left in far-off lands to be adopted by people who can give them a better life. Lalum is adopted. This is Fire Emblem, where there are no coincidences; any character mentioned offhand will somehow become important to the plot. (Note that every last character mentioned in a support conversation in Blazing Blade that does not appear in that game does appear in Sealed Sword--Geitz's brother, Canas's mother and son, Hawkeye's daughter, etc.) Note, also, that this is a franchise with a history of adding a bunch of unexpected familial relations between its characters (most notable in Radiant Dawn, but also the whole Nino/Canas thing in Blazing Blade). It would be a unique occurrence if something like this was mentioned and it didn't refer to someone else in the game. Also, in the Lalum/Oujay conversation, Oujay seems pretty uncomfortable with Lalum's flirtatious advances and is specifically trying not to stare. There isn't much that can explain why he would be uncomfortable, but it's possible that something in his subconscious is telling him that starting a relationship with this girl would be a bad idea.

All the games take place on the same planet. Also, the player takes the part of the Tactician Spirit, a spirit who aids the cause of right no matter what.

Someone had to say it.

Additionally, the games all take place in the same order they were published, with the exception of Fire Emblem 6/7. The Dragon Laguz from Tellius are the deteriorated descendants of the Dragons of FE7/6. About half the size, as well.

Also, the Tactician Spirit decided to try out a new spell he recently acquired, "Incarnation", and appeared in Elibe. This is why he never was seen again after the Dragon is killed. He carried a Time tome, which allows him to rewind time until he wins a battle.

Again, Nasir is Nils' descendant. Look at him! You know it to be true!

• It's been confirmed that the first five games take place in the same world with FE4 being the chronologically first game.

Sword of Seals 16x/Tower of Valni 8/Shadow Dragon 24x is a TARDIS

1. In Shadow Dragon Nagi, who is apparently the reincarnation/avatar/successor/something of Narga (who is one of the few things to exist in more than one setting), resides in it. (Would this make Narga a time lord?)
2. It appears in the series four times with minor differences (mostly tile set). All of them are optional/cut scene only areas.
3. What else could explain why they look the same? (Image of Shadow Dragon 24x needed...)

FE 6 Karel is actually Guy from FE 7

It would explain why they're both called the "Saint of Swords" in their FE 7 endings and why Karel's personality is so different between games. Karel and Guy probably fought each other sometime after FE 7, and if Guy won that fight, he might've taken his old master's name as a show of respect.

• • But why would Guy consider Karla, Bartre, and Fir family?
  • Alternate theory: Karel killed Guy, thus the Saint of Swords title was transferred to him, and the shock was enough to knock the crazy out of him.
    • Alternate theory extension: Guy asked Karel to kill him after leaving Priscilla.

Spell books are the material components for spells

Each page is written in a magically charged script; they're more like blueprints for the spell. This explains why mages can run out of spells from a given spellbook, and why they can't cast without a book. When they cast a spell, they tear a page out of the book, and use it to cast the spell; the page is consumed by the effort. When they have used all the spells in a book; they obviously can't continue casting from it. You can only put so much magic into a single book; which is why the really powerful spell books have so few pages in them.

• • Canon, except it's the INK on the page that's the catalyst for the spell. Breaking a Tome in Genealogy results in an "Empty Book", and in the OVA, you see the ink on Garnef's tome materialize into his spell.

The dead friend Renault wanted to bring back is Kishuna.

Renault's battle conversation with Nergal in Hector's story suggests that Nergal was still experimenting with morphs when Renault came to him, and Kishuna was Nergal's first morph. Renault also refers to what Nergal gave him as "soulless" and "an empty vessel". Unlike most of Nergal's morphs, Kishuna isn't even capable of speech, which could lend to him giving off this impression. It would be interesting to see if anything unusual would happen if Renault were to be hacked to be able to attack Kishuna in Chapter 32x...

• That actually seems to be shot down in the game; Kishuna is specifically referred to as the "only morph he made with emotions", implying that Kishuna is not his first morph. Also, while Renault friend is likely the first morph, part of the reason Renault was turned away from it was because it was an emotionless shell of his old friend.
  • What if Kishuna was a Super Prototype, and all the morphs made after were emotionless?
  • Besides, although we see that Kishuna has emotions, he never, ever speaks. Him not speaking was why Nergal cast him aside, believing him to be a failed test. That not speaking would have Renault think that Kishuna was emotionless as well, also rejecting him. So for me at least this feels like Kishuna had emotions, but could not express them for some reason
• I did it via a purge tome and a bunch of energy rings (for range). He didn't say anything. Though it could just be the devs not thinking of this possibility. Given that this is FE, I'd still say Kishuna is the friend Renault tried to revive.

Frey is the canonical sacrifice in FE11.

(Completely stolen from the Fire Emblem wiki.) The prologue of Shadow Dragon is an entirely new level that was not present in the original game, and in it, you gain control of a few of the units that were in your starting army in the original: Marth, Jagen, Cain, Abel, and Gordin. You also gain control of one brand-new character, Frey. During this prologue, you have to sacrifice a unit for use as a decoy, who will be Lost Forever--not even the staff that revives the dead late in the game can bring that unit back (although by that point, why would you want to?)--in order to get a door to open. (You can avoid the use of the decoy by purposely killing Gordin, who appears as a recruitable "enemy", instead of recruiting him.) Not only would this explain where Frey was in the original game, but in Hard mode, where the prologue is automatically skipped, Frey is once again missing. It is therefore speculated that canonically, Frey sacrificed himself to allow Marth to escape prior to the start of the first game.

• That's fairly obvious. The real question is why they bothered putting in Frey when most people are just going to sacrifice Jagen anyway. Better (potential) stats, prettier face...
  • To keep the number of units the same. Basically, by allowing you to choose your sacrifice, you get to change the events that preceded the beginning of the story proper.
    • Wouldn't this be sorta deemed false now in light of FE12 since he shows up alive and well during the tutorial areas as well as joining up during the main game?
      • Just the opposite, in fact; a conversation between Frey and the player unit confirms that Frey was the canonical sacrifice, and that he was severely wounded and left for dead by the enemy, but miraculously survived, albeit with lingering effects from his injuries.

The sacrifice/decoy in FESD is not dead, but was captured by Gra's troops.

As an add-on to the previous WMG, the character used as the decoy (canonically Frey) isn't dead. They don't actually say anywhere that the decoy was killed, and, as mentioned above, the Ohm Staff cannot revive the decoy. Why? Because the decoy isn't dead in the first place. Being killed a few years before the main game isn't a suitable explanation; you can revive any other character that was lost in the Prologue. With a remake of Book II on the way, who knows? Perhaps Frey might make a reappearance...

• Confirmed.

Canonically, Norne never joined Marth's group in FE11.

Similar to how Frey is the canon sacrifice, one can assume that Norne is, in canon, killed during the prologue or simply never actually met up with Marth, seeing as how she doesn't appear in any mode except Normal, which is the only one where the prologue isn't skipped.

The world behind the Dragon's Gate in FE7 is in fact Akaneia, the continent of FE1/3/11.

The Dragon's Gate is on the same spot as the Ice Dragon Temple in FE3. Nils and Ninian also mention how men and dragons live there together, which applies to Akaneia as well.

All people in 9 and 10 with green hair are related.

One of Elincia's relatives took a trip to Begnion long before the game started. Apperantly having a negligable amount of self-control, he ended up producing fraternal twins with one woman, and a single boy with another. The second girl was actually a branded, and the child was Stefan. He was likely also Sothe's father. The twins were Sigrun and Rolf's mother; they don't get along well because the latter is a horrible person. At some point before meeting Rolf's father, she had another child, who she abandoned at an orphanage in Daein. We now know that that child as Aran. The rest is history.

Miledy and Zeiss are Priscilla's children

After her tragic relationship with Heath, she had married Erk as part of a political marriage while bearing Miledy and Zeiss in secret. Erk found out and sent them off to Bern as Wveryn knights which a polite way to disown the both of them

• They are too old to be Priscilla's kids, though. Not to mention Zeiss is younger than Miledy, which would mean Priscilla would have had to somehow manage carrying and giving birth to Miledy without the whole army knowing. Unless she bore Miledy first (pulling a Louise and getting pregnant near the end of the storyline), then got pregnant with Zeiss after the game's end just before Heath left. ...both of these would make for interesting AU fic, actually.

Wendy's parents are Oswin and Serra

There are no female A-knights in 7, and they're rare in the setting in general, so if it's in Wendy's blood at all, it must be from her father's side. Wendy has crappy DEF and STR for an A-knight (even taking starting at level 1 into account). Of course, you could argue that's just due to being a girl, but it wouldn't make sense for her mom to be someone like, say, Vaida. It's clear she's uncomfortable with the role and that would make sense if her parents were radically different. Finally, she has pink hair, which is unusual even for Fire Emblem. Now, what canon pairing involves a male A-knight and a non-combat-type female with pink hair? Bingo.

Mia's archrival is outside the Tellius timeline.

Lowen is the cook/meal delivery man in FE 6.

We know Lowen as the eager-to-please Pheraen cavalier in FE 7, in which he spent an entire set of supports lecturing Eliwood on the importance of proper nutrition, as well as revealed that he had been cooking for the army surreptitiously. In FE 6, Lugh mentions in his supports with Chad and Ray that the man who delivered meals to them in the field has given him extra baked tarts. Klein also mentions, in his A support with Percival, the cook's concern that Percival doesn't like his meals because he eats them without expression. Neither of these men is given a name, but they both seem to share the same concern over making sure everyone in the army gets enough to eat and, what's more, that their food actually meets their preferences and tastes good (which, from what I've gathered, is unheard of in any military). It's likely that at least one of these guys is actually Lowen returning to (half of) his previous role, if the two unnamed caterers aren't, in fact, the same person.

The Five Orbs from Marth's Fire Emblem Shield are the Sacred Stones in Magvel

Five orbs in Marth's Shield, Five Stones for each of the main nations in Magvel. With the heavens sending the stones to Magvel, inter-world travel is possible. The Darksphere, more attuned to darkness, was the one used to seal away Fomortiis, but its dark energies allowed his soul to endure for 800 years. The Starsphere, increasing the stat potentials in Archanaea, was sealed at Renais, the nation of the high-potential Lord characters. The Geosphere, governing earth, goes to the desert wastes of Jehanna. The Lightsphere, counter to the Darksphere, was enshrined in the holy capital of the continent, Rausten. This leaves the Lifesphere to go to Frelia, because... Frelia provides a safe haven to provide safety for Eirika once Renais gets destroyed, perhaps?

The Juna Fruit isn't actually exclusive to Magvel.

In Sword of Seals, the character Gonzales can be found at level 12 on one route, and level 5 on the other, but his stats are the same regardless. This is consistent with the effects of Juna Fruit. Note that to drop 7 levels, Gonzales would need to have eaten at least two Juna Fruits, as there is a 5-level maximum per fruit. How he managed to get two of what is obviously a very rare delicacy in Elibe is anyone's guess, though the most likely scenario involves the corrupt nobles who push him around seeing him only as a weapon and therefore thinking only to make him stronger.

Jahn is full of crap and has no soul.

Zephiel's explanation to Roy (and before that, presumably Zephiel) has one glaring flaw: it relies on the idea that dragons don't possess all those silly emotions humans do. Even neglecting Ninian, Nils, and Sophia because they are only half dragon (though Ninian and Nils grew up beyond the gate and would have learned the dragons' social norms...) it only takes about five seconds looking in Fa's general direction to see that this is obviously bullshit. Thus, Zephiel's justification for war and both the trustworthiness of Jahn's words and his motivations are called into question. But why would Jahn tell this to Zephiel, who was in a position to believe him as he had only met Idoun, and Roy, who really should have seen enough of Fa by then to know better?

Because, much like the case of Sonia, though Jahn believes himself to be a true dragon, he's really just an especially intelligent war dragon. In fact, all of Elibe's fire dragons were the same, a fact the other dragons may or may not have understood. Idoun didn't create the first war dragons, just mass-produced dumb ones that could be sacrificed by the score. The original fire dragons were created long before the Scouring as guardians and shock troops in case of war, and a few managed to worm their way into positions of power as time passed and the other dragons forgot that they didn't have the capacity for empathy and so really shouldn't be trusted with it. Even after the war, the fire dragons continued in their role as guardians - besides Ninian and Nils, the only dragons that cross the gate when Nergal opens it are fire dragons because they are the only ones there, keeping watch on it.

Building off of this, it's highly likely that Jahn's version of events is just as wrong as history's. The conflict that became the Scouring may not even have started as humans vs dragons at all. If the Eight Heroes' tale followed the normal Fire Emblem patterns, the war likely started as a sudden invasion of one country by another, each a mix of humans and dragons, that slowly changed into a conflict of species as alliances shifted and a hidden power - like, say, Jahn and his brethren - manipulated events behind the scenes. The Heroes' army may well even have had a dragon or two of its own - Aenir, perhaps, or Melitha.

• Yeah. Thanks for removing any moral ambiguity from the Scouring by claiming the Fire Dragons, the main aggressors on the Dragon side, were just soulless weapons, and thus OK to kill, and the one Fire Dragon we see in all of the Elibe who isn't a War Dragon actually is not only a War Dragon, but also a liar who may have hidden the "true" reason for the conflict for shits and giggles. (which ignores the fact that Jahn spent most of the century after the Scouring recovering from his wounds. He only got enough strength to send Zephiel that hologram after Idenn's awakening recharged the Dragon Temple) A few (more) problems, if the creation of War Dragons predated Idenn, then that means the Dragons already had a means to make War Dragons, and thus would have no need for a Divine Dragon to have to transform into a Mage Dragon (Demon Dragon. Whatever.) Which would also mean that the Divine Dragons would have no reason to run from the other Dragons, and might even have sided with the other dragons instead of staying neutral. Also, Jahn didn't tell Zephiel about the Scouring, Zephiel looked it up himself and even knew somethings that Jahn didn't (such as how Hartmut sealed Idenn and why). All Jahn did was align himself with Zephiel because they had similar goals.
  • Jahn merely being a War Dragon would explain why he goes down as easily as the generic dragons, when Athos, Eliwood and Hector combined could just barely beat a single Fire Dragon already weakened by Ninian... My impression was that Divine Dragons could create War Dragons. But the Divine Dragons did not want to participate in the war against the humans, so they refused to help the Fire Dragons. (If we follow the theory that Nils and Ninian's world is Akaneia, then these Divine Dragons could be the same group that protected the humans against the Earth Dragons in FE 3's backstory). So the Fire Dragons captured Idoun and destroyed her soul - not to give her the power to create War Dragons, but so she would follow their commands. Jahn was created via the same method as the morphs, to be a commander of the war dragons/servant of the Fire Dragons. (Nergal first discovered how to manipulate quintessence from the dragons in Arcadia, so it's not such a stretch). After the Ending Winter, his job was to protect the Dark Dragon and wait for the age of the dragons to reappear. (The Fire Dragons may well have been wiped out, and like Idoun, Jahn is working on behalf of a long-dead master. Ironic...) When a human who had released the seal on Idoun, had some secondary source knowledge of the Scouring, and had a cynical viewpoint on humans appeared, Jahn fed him a story that would reinforce his view on humans.
    • Except Jahn didn't feed Zephiel any story. Zephiel knew most of this himself. Jahn even admits that through his research, Zephiel knew some things that he didn't. Also, the story explictly states that they needed a Demon Dragon to make War Dragons. And if Jahn is a War Dragon, how can he think? How can he talk? The one named War Dragon we see is Ain, who can only say simple thoughts like "burn" or "die" and doesn't really show any signs of real intellegence at all. I feel that trying to argue that Jahn is a War Dragon that they made able to "think" based on a separate set of beings is really reaching. And Idenn was treated as the War Dragons "commander" anyway. As for why the Fire Dragon in FE 7 is stronger than the other pure blood Fire Dragon, I'd just say Gameplay Story Segregation. However, also note that Roy and his army were packing all of the Divine Weapons plus the Sword of Seals which surpassed them, while Eliwood and pals had 4.
      • Jahn heard about the Heroes' battle against Idoun from Zephiel, but the rest was based on his own experience. 2 "Idoun was still young, but she had no problems in fulfulling our purposes, except for one... Her heart was not with us. She would not follow our commands. … We destroyed her soul to make her follow our every command." This implies Divine Dragons can create War Dragons, but Idoun refused to do so for the purpose of fighting humans. 3 For the purposes of this WMG, you might as well ask how Sonia can think and hold conversation, and Denning can't. This theory relies on Morphs and War Dragons being created in the same way. There's no basis for it in canon, true, which is why it's called Wild Mass Guessing and not Perfectly Reasonable Guessing. But there's no hard evidence against it, either. 4 "The Dark Dragon is an 'object' meant to bring hope to us Dragons again. It is no leader." 5 Jahn can be OHKO'd by a single Divine Weapon, which you can't say for the Fire Dragon. But Gameplay Story Segregation is the most likely reason why FD > Jahn.

The power Bramimond sacrificed his identity for wasn't Apocalypse, but Aum.

In every Fire Emblem world where it is known to exist, the most powerful, sought after, and elusive of magics is the ability to bring back the dead. Yet, despite there being no apparent foreshadowing of his ability to do so, Bramimond comes out of nowhere in the ending of Blazing Sword to bring back Ninian. Deus Ex Machina, right? Except that we know that Bramimond traded his soul for the greatest of dark magics. Since most dark magic is used for killing things, the obvious assumption is that that refers to Apocalypse, but we also know that Nergal frequently used dark magic to create at least a mockery of life - his morphs. It's not a great leap to say that this might have been his pale imitation of Bramimond's greatest accomplishment. Of course, this means that Bramimond would have had cause and motivation to give everything to bring someone back from the dead - perhaps an unknown family member or love interest, but due to Conservation of Detail most likely one of the other heroes. My guess, for the best symbolism/irony/shipping, is Elimine.

Limstella was modeled after Nergal's wife.

Before the chapter in which you fight her, Nergal comments on how Limstella was the most powerful of his morphs. However, Limstella is a very plain woman. Other than the black hair and yellow eyes that all morphs come with, she doesn't exactly stand out. Not exactly imposing enough for someone to choose for their champion. This could be a case of Boring but Practical, but considering that Nergal lost his sanity to the dark powers trying to bring his wife back from the dead, it wouldn't be a far stretch to believe that when making his most powerful morph, that some lingering presence of her in his mind influenced his design.

• • She would look a lot like Ninian if her hair and eye color were to be changed appropriately.

The Creature Campaign takes place after the Epilogue of Fire Emblem: The Sacred Stones.

Most of the characters that can be unlocked in Creature Campaign died during the course of the story, but King Hayden of Frelia didn't. However, it's likely that he did die at some point not too far into the future, as the endings for many Frelian characters mention Innes's ascension to the throne and Innes's own ending specifically states that he became king after his father died. Unlike the epilogue of Blazing Sword, Sacred Stones's epilogue doesn't mention the deaths of any playable characters except for those that actually died during the course of gameplay--not even Cool Old Guy Duessel, although his regular ending does mention "his remaining years". After selecting Creature Campaign in a given file and saving the file once, the Epilogue from that clear data can no longer be viewed. Theory: the Epilogue is "written" 5-10 years after the events of the game, while all participants are still alive (and in the case of those who were paired up, have started families), and that the Creature Campaign takes place after that has already been written and is therefore not included in the history; Hayden is already dead by this point.

• The exception, oddly enough, is [[spoiler:Myrrh, whose normal ending says she "lived a long and full life", past tense, despite the fact that she'll likely outlast every other character in the game by millennia. To a lesser extent, projecting the futures of some of the children of the younger characters might mess up the timeline if everyone is supposed to still be alive unless Duessel is in fact Younger Than He Looks.

FE 13 will start a player created lord

My Unit was a test.

• • Half-Jossed, half-confirmed. From what we know so far, Krom seems to be the obvious Lord of FE 13, but the My Unit system will return, and it's hinted MU will have more connection to the story this time round.

Harken is the mystery villager

In one village in FE7, a man who doesnt reveal himself claims that he dresses in the garb of the Black Fang, but is an ally and a loyal citizen of Lycia. All these apply to Harken who suicidally infiltrated the Black Fang to kill as many members as he can as revenge for Elbert.

• This could be confirmed - it's not shown on screen, but ROM-probing shows that the game does load Harken's portrait data for that sequence in addition to that of whichever unit is visiting the village.

Athena is from a royal family in Akaneia.

Think about it. Though her Funetik Aksent muddles her words up a bit, she refers to herself in the third person using pronouns such as "we" and "us." This is a trait that royalty of European countries (such as England) wherein the ruler would use the plural form in order to suggest that they carried the backing of their ancestors when they made a decision. Also, she has a shadowy background, having been saved by villagers from drowning in a river. Where did she come from beforehand? Perhaps she was a runaway princess from a kingdom being trampled under Doluna, Grust or Medon's campaign? And speaking of Medon, Athena and Princess Minerva are linked by their names, which are the Greek and Roman equivalents of one another, respectively.

The Falchion and the Tyrfing are the same weapon

It's pretty much confirmed at this point that Akaneia is the distant future of Jugdral. The two weapons resemble one another, so it's entirely possible that the two weapons are one and the same, but with different lore attached to it.

• • The Falchion was made from one of Narga's fanged teeth. Dragons have more than one tooth. Maybe they're sibling weapons.

Sword of Seals's Gale is the son of Blazing Sword's Heath

This might seem like a longshot, but hear me out. In Heath's nonpaired ending, he relocates to Ilia and continues fighting as a mercenary. In Sword of Seals, the reason Gale is originally denied the position of Dragon General is because he isn't a native of Bern (despite being one of Bern's "trademark" Wyvern Lords). In other words, my theory is that Gale was born in Ilia as Heath's son, and became a wyvern rider like his father, and eventually traveled to Bern and became a Knight.

Bramimond was in fact originally female.

Bramimond's name is another of the series' innumerable references to The Song of Roland. While such references don't necessarily have to bear any resemblance to their origins, it's worth noting that the original bearer of the name (which started out with an 'e' on the end of it) was the wife of the Saracen king.

Granted, Bramimond is pretty consistently referred to as "he" by just about everyone before admitting it really doesn't have a gender anymore, but, well, a thousand years is a long time, even for Athos, and who knows just how much of that time Bramimond spent as a blank slate.

• • I'm not quite sure anymore, but I do vaguely believe that the German translation of the game did in fact refer to Brammimond as a female.

The people in these games are not truly human.

Confirmed in Path of Radiance and Radiant Dawn, the Laguz and Beorc evolved from scaly creatures into things which looked a lot more like their "goddess". Why stop there? Who is to say we are looking at are humans in any of these games? 1:no game is on Earth, 2:strange phenotypes are always common and 3:silver hurts them more than iron and steel. Silver is not particularly dangerous to humans as far as metals go but many monsters hate silver.

Briggid was resurrected by her Holy Weapon after the Battle of Bahara, the same way Levin was.

Because it seems a tad bit too convenient to have another character with a holy weapon survive the exact same battle and have more or less the same symptoms later (the memory loss).

Ike was abducted by Aimee.

Or seduced or blackmailed or something. Word of God states that Aimee and Larabel are the same person. This raises questions because she uses the name Larabel on a different continent but there is only one continent on Ike's planet. This means one of two things: 1. She is very old, old enough to live the great flood, the shifting of plate tectonics to create new land and or some seriously prolonged volcanic activity. 2. She is able to move between different worlds and or timelines somehow.

Given that technology is advancing on Tellius, this shows the planet is not in Medieval Stasis and thus cannot be the same place as Marth's games. While not evil, Aimee's shown to have questionable ethics, charging you full price for her wares when even when the world is about to end. Aimee also doesn't hide her intentions to take Ike and his resistance would have failed if not for Soren's interference. Eventually, Aimee anticipated and got around Soren's meddling. They are on another planet or in another timeline now and left no trace, everyone else can only assume they fell over board on a fishing trip or something.

Anna is a Time Lord, and Jake is her companion.

This actually may have some tangential canon basis, given how in Awakening she presides over the way of meeting characters from other universes.

The Tactician from FE7 is Harry Paget Flashman.

Think about it: he does very little actual fighting or real work, letting Lyn handle the bandits in Lyn's Tale. Despite that, he manages to come off as quite the hero, and all the records place him as indispensable to Nergal's defeat, and who knows? Maybe he really was, in the typical Flashman way. And if all the tactician-fics are any indication, he does a lot of unwarranted bragging, especially when it comes to nailing the chicks. All we need now is for some clever bastard to blackmail him into joining Eliwood's little warband, and it all fits together.

All the continents are part of the same earth

While there is a similar theory already here, mine is more specifically about the continents themselves rather than the time. Wondering about things like planet size (because when you have multiple continents the size of Asia, it takes a larger planet than Earth to keep them from touching), would be somewhat of a handwave, but almost required in this theory; however, I digress. You COULD narrow it down to three continents, Akaneia being the same as Jugdral (though I will leave that debate in of itself open for discussion- who knows why Word of God would say that Jugdral took place thousands of years earlier?); leaving us with both Magvel and Elibe as the other two continents. While one must wonder why it takes the whole "Other World" concept of Awakening to reach characters from the other series, I think it has more to do with the major time differentials over anything else.

The Tactician from FE7 is one of the lost Primarchs

He was a ridiculously gifted tactician as shown by how he led a rag-tag army multiple times against superior numbers to victory with zero/minimal loss. The Emperor heard news of an army that continued to break the odds led by a mysterious tactician and he understood that he had found one of the primarchs. After Eliwood's coronation, the Tactician had to immediately leave for a reason that was never specified. The reason was that he was approached by the Emperor shortly after the defeat of Nergal and he agreed to take command of a Space Marine legion. It was mentioned that he disappeared after the events of the game and all attempts to locate him was futile. This is because the Tactician was not in Elibe (or the planet it was on for that matter), he was in another part of the galaxy fighting in the Great Crusade.
