While Square Enix has only recently begun to make more sequels and compilations, there have always been references in the Final Fantasy series that have made them feel connected. While these may not prove actual inter-game connectivity, they do show that there is a possibility, that has thrilled and terrified fans for decades; the possibility that all the games may in fact be part of a larger story. However, Square has been suspiciously silent the last few years, so until an official statement is made, we can only speculate.
Final Fantasy VIII and Final Fantasy XEdit
The only evidence I have here is the Moogles/PuPu. They both exist in only these two games. They are creatures of wonder in VIII. But dolls in X. So if there are dolls of the creatures in FFX that means someone would have had to see pictures of the creatures to make them, meaning they existed in some form in the timeline. So FFVIII would have had to happen at some point before FFX. (just speculation)
Final Fantasy II and Final Fantasy IVEdit
Main evidence here is in Final Fantasy II in Deist there is a young boy called Kain, who is presumably the son of the Dragoon Ricard Highwind and wants to be a Dragoon one day. In Final Fantasy IV one of the main characters is a Dragoon called Kain Highwind. In the DS version of Final Fantasy IV, Kain mentions that his father's name was Ricard, and that he died fighting an evil empire, showing that the connection goes both ways.
The Japanese scenario guide for IV mentions that Cecil's Deathbringer sword once belonged to a dark knight named Leonheart, a character from II..
Also, in both games, there is a town named Mysidia that is full of mages.
Additionally, The Emperor in II and Golbez in IV share the same sprite (character design), as well as possessing similar powers. Both are powerful mages, and both possess the ability to brainwash people (The Emperor does this to Leon, while Golbez does it to Kain). The only difference is that Golbez' brainwashing ability comes from Zemus, not his own magic.
Final Fantasy IV and Final Fantasy VIEdit
Due to Final Fantasy IV being called Final Fantasy II and Final Fantasy VI being called Final Fantasy III when the two were originally released in the US, it was easy to assume that the latter was the sequel to the former. For example, the War of the Magi could be the war in Final Fantasy IV, and the Warring Triad descending to the world to wage war could be a reference to three unnamed Lunarians coming from the Second Moon.
General evidence to support this largely includes the Ancient Castle. In Final Fantasy IV, Baron houses a secret chamber in the right tower where Odin is fought after he is struck down by Kainazzo. In Final Fantasy VI, Odin is petrified by a nameless sorcerer, and a hidden passage in the left wing of the castle leads to a chamber where he can be upgraded into Raiden. The same passage also contains the Blue Dragon - although the identity of Odin's opponent is not revealed, if it were the Blue Dragon that defeated him, this would place the story of his defeat in direct parallel to his death at the hands of Kainazzo. In addition the architecture of the two is similar.
The world maps of the two games also share many similarities. Baron Castle is located where Figaro Castle would be, which fits the location of the Ancient Castle lying under Figaro's burrowing route. Doma Castle is in the north-east of the world like Fabul, and both are connected to the main continent by a narrow chain of land. Mt. Crescent lies where a chain of islands exist in Final Fantasy IV - if there was a flood, the mountain range would become a chain of small islands. Mt. Ordeals also stands in roughly the same location as the Cave to the Sealed Gate, and if the Warring Triad are somehow Lunarian in origin as mentioned above, it would make sense for Mt. Ordeals to be in the location of the Cave to the Sealed Gate, as it houses the spirit of KluYa and also is near the resting place of the Lunar Whale.
Evidence against these worlds' connections lies in the lore of summoned monsters and their origins. In FF IV, they live in the Land of Summons, beneath the earth. In FF VI, the lore implies that they cohabitated with humans until the War of the Magi, in which they created their own world.
Final Fantasy VII and Final Fantasy X & X-2 Edit
In Final Fantasy VII, the main catalyst of the games events, and the organization considered by some to be the actual main antagonist is the Shin-Ra Electric Power Company. It uses the Lifestream, the planet's life force, to create an energy source known as Mako. Mako is then used to fuel the great cities all over the planet.
Farplane data. The more I study it, the more fascinating it gets. There's limitless energy swirling around in there.... The life force that flows through our planet... I think. With a little work, we could probably extract the energy in a usable form.
This causes the main characters to get very excited at the idea, however he cautions that it would take "generations". This connection would seem to imply that Shinra is the ancestor of President Shinra.
Another connection between the two games are pyreflies. In Final Fantasy X, they are small creatures like balls of life force who have the ability to harbor, project, and even materialize the memories of the deceased. They also have the tendency to cluster around the will of a person who is "strong willed" and who refuses to be or isn't sent. In the movie Final Fantasy VII: Advent Children, the three main antagonists are called avatars or physical manifestations of Sephiroth's will. When their leader, Kadaj dies, he dissolves into small balls of light, similar to pyreflies, instead of the regular fluid look of the Lifestream.
It should also be mentioned that the Farplane and the Promised Land are also very similar. Both are seen as final resting places of the deceased. They are also both the area where the planet's life force resides, and they are both known to contain energy that could, at least in theory be harnessed to fuel human cities.
Another smaller connection between the two games is that Moogles are fictional beings, and also the moogle toy held by the girl in Final Fantasy VII: Advent Children is identical to the one held by Lulu in Final Fantasy X.
Note: Interviews with scenario writer Kazushige Nojima and producer Yoshinori Kitase in the Final Fantasy X Ultimania Ω and Final Fantasy X-2 Ultimania guidebooks, have revealed that Final Fantasy VII and Final Fantasy X-2 share a plot-related connection, in which the Shin-Ra corporation in Final Fantasy VII is founded by descendants of Shinra of the Gullwings in Final Fantasy X-2.
Final Fantasy III and Final Fantasy VIIIEdit
In Final Fantasy III there was a wizard named Hyne or Hein. He uprooted the Elder Tree from the Living Woods and mobilized it into a floating palace. He then captured King Argus (under whom he used to work as an advisor) and his entire court. Hein was eventually defeated by the Warriors of Light. In Final Fantasy VIII, there was a tale told of a sorcerer named The Great Hyne.
...the creator of mankind, and the first sorceress ever to exist. Upon creating the first humans, Hyne went into a deep sleep. When he awoke, he decided his creations had become too advanced, so he decided to kill all of the human children. The humans, however, resisted, and a huge battle between Hyne and the humans began. After many years of fighting, Hyne surrendered and gave half of his body to the humans, and that is where the tradition of Sorceresses passing down their powers started...
It is worth mentioning that when the Warriors of Light battle Hyne in Final Fantasy III, he is a skeleton, meaning a good amount of his original body is missing. This may be where the idea of Hyne giving half of his body to the humans originated.
It is also interesting to note that Hyne lived in the medieval world of Final Fantasy III, while the tale told of him was in the futuristic world of Final Fantasy VIII. The time periods then also match up nicely as the true tale of Hyne would have been corrupted after centuries of retelling, especially when considering that a similar tale concerning a division of power, that of Xande and his contemporaries, exists in the Final Fantasy III setting. Doga's magical inheritance thus may be the true origin of the sorceress power (Unei's power, meanwhile, may live on in Ellone).
The world maps of the respective games also have a roughly comparable continental distribution. For example, the Floating Continent in Final Fantasy III is situated roughly at the same spot where the Deep Sea Research Center in Final Fantasy VIII is found. Beneath the Research Center are ruins that indicate that there had been an ancient civilization founded here. These ruins could have been the Owen Tower in Final Fantasy III.
Curiously, in Ultimecia's Castle there is a clock tower. The hands on the clock pointed at III and VIII. This may be a subtle hint about the games' connection. But then again, nothing can be proven.
Another important point to notice may be the fact that ultimecia's castle is floating and is being held at a certain height from the ground by huge chains. If we consider the location of the deep sea research facility being above the owen tower, which is the powerhouse of the Floating Continent, it is quite possible that ultimecia and Xande's way of keeping the land mass in the sky is the same.
Final Fantasy and Final Fantasy IXEdit
Although Final Fantasy IX had many allusions to past games, the most prominent allusions were to the original Final Fantasy game. A character named Garland makes an appearance as a villain, as do the Four Fiends of the Elements in their Final Fantasy incarnations (a separate group of Fiends also appeared in Final Fantasy IV). Usually mentioned as a connection to (or the genesis of) this theory is a line in Final Fantasy IX, stating that Garland once tried to control the cycle of souls by force, but failed. This is held to allude to the events of the original Final Fantasy. Also, an examination of the world maps of Final Fantasy I and IX show a distinct similarity to each other, with the positioning of the western continents in particular, but this may just be a coincidence.
There is also the matter of Princess Cornelia, meaning the kingdom of Cornelia from Final Fantasy Made a return in IX.
Also, both games have a volcano stage, called Mount Gulug in FFIX and Moung Gulg in FF, in which even the theme song is the same.
Final Fantasy X and Final Fantasy VIEdit
It is entirely feasable that X and X-2 are the War of the Magi. Okay, Square may have confirmed connections with seven, but need I remind you of the "Mt Kolts" signs in VII and CC? At any rate, this section should make for thought provoking reading. Here, I treat the War of the Magi as more of a legend than historical fact; the nature of events was exaggerated and slightly altered over time.
Consider the Warring Triad: The Goddess, Doom (reanamed Fiend) and Poltergeist (Renamed Demon). The Goddess is essentially made up of 2 parts: the statue of the woman stands on a medusa like head similar to the third form of Yunalesca. The woman has brown hair in a style similar to Yuna's. Behind the figure is a large golden disc, resmbling the Sun. Now, if we treat the statues as Fayth, rather than the petrified remains of the gods, we can see symbolism: Yuna is shown, appearing to break free from the mind(head) of Yunalseca with the Sun at her back. In X, Yuna ended the summoner's pilgrimage started by Yunalseca(at the behest of her father, Yu Yevon) with the aid of Tidus(His name means "Sun"). Next, the Fiend. It's a large, fairly blobby black shape, originally called Doom. Sin is the bringer of destruction, and is in essence the Fiend left behind by the Fayth of the Final Aeon. Its appearance is similar to braska's final aeon: both have a "chaos like" upper body, with yellow horns pointing straight up, and a lower half concealed by grey material. For this theory, fiend represents Sin and Yevon. Finally, the Demon, or as I prefer to think of it, the Poltergeist. Again, this one appears to have 2 parts, or at least, 2 well defined faces. one is that of a humanoid man, and the other is that of a beast, which may be a seperate entity.at any rate, the Human seems to be in command of the beast, from their body language. This is largely irrelevant, but reinforces my point. The Name of poltergeist serves this theory well, for in X, there were three groups at war: Yuna's Guardians, Yevon and Seymour Guado. When Seymour came back from the dead, he always had a sidekick of some sort (mortichoris, mortibody). As Seymour flux, he carried a large staff, similar to Poltergeist's halberd. Finally, if the two parts are indeed one body, their arrangement mirrors that of Anima, particularly the more feral face below, with its arms outstretched, similar to Anima's Overdrive.
And now, let's bring it all together. The War of the Magi was thought between these three powers, represtned by Yuna, Sin and Seymour. Since ultimately, every one in Spira sided with one of these groups. Their battle lasted many years(even though Yuna's group did not appear for some time, their ideals were similar to those of the al bhed). In VI, the espers were humans once, who had been infused by great amount of magic in the cross fire between these three. In X, the Aeons are the souls of those who died to defeat Sin. This is where we see things change over time; the metaphorical cross fire became a literal event. As for the event which turned them into statues, where the three decided to neutralise each others power, well...that's covered to. You'll remeber that there were multiple endings to X-2. Now, most accept that the hardest to get ending must be the real one. But surely, humans being flawed would take the path of least resistance? Remeber, there is an ending where Vegnagun destroys spira, with a big white light. Need I remind you that Kefka did the exact same thing with the Triad's power? The Three did not choose to neutralise each other-Yuna destroyed Sin and Seymour, and was herself destroyed by Shuyin. However, with so much death, the pyreflies could easily gather. In FFVII, Aerith took phyiscal form in the Lifestream, could not these three dominant personalities also have bound together Pyreflies and became Fayth? Now I realise this theory runs short, since surely all of Spira's inhabitants died? Yes, but so did Auron an Tidus, but they still managed to walk around. The people of Final Fantasy VI could be unsents, or something similar, created by the three Fayth as they dreamed about the destroyed world. As the three are in essence, human, they may have overlooked the other races.
Now for Geography. The Calm lands could easily have become the Veldt, and Macalania Forest, where the entrance to the Farplane is located, could have become the forests around the gate to the Land of Espers, or even the Phantom forest. Figaro is the New Home the Al Bhed created. Perhaps its transport capabilities were put in place to prevent a repeat of events in X. Now you may be thinking that doesn't sync up to the map of spira, but I've already compared Vegnagun to Kefka in terms of power. If Kefka was able to carve up the world of balance, why couldn't Vegnagun carve up Spira?
Final Fantasy VII and Final Fantasy: The Spirits WithinEdit
In Dirge of Cerberus, it is revealed that the planet has a mechanism to secure its life, which is Omega. When a world destroying event happens, there's an overflow of souls going to the Lifestream (off all the people dying at once), this activates Omega. Omega uses Chaos to kill everything in the planet (that is, harvest lifestream), and after all living things are wiped out, Omega will take the planet's lifestream and fly off into space, so it can find a new home for the lifestream.
In Spirits Within, the Phantons are alien ghosts from another planet that arrived on earth in a meteor. Their original planet was destroyed in a huge explosion after a war between two rival factions. On Earth the phantons killed every living thing on sight, consuming their souls. The collection of all of the planet's souls is called Gaia in the movie, the phanton souls are refered to as the Alien Gaia, while Earth's Gaia is of course called Earth Gaia.
The idea of Omega destroying everything during a time of crisis and flying off into the space is similar to what happenned to the Phantons: during a crisis (their war), all life was exterminated, the planet was destroyed and it's lifestream flew off to another planet. The Phantom Gaia attempts to infect Earth Gaia at the end of the movie, probably so it can to take over the planet for itself, creating a new home.
In Spirits Within the "lifestream" of earth is actually seen, and it is under the earth's crust, like in FF7. Lifestream and Gaia are actually quite similar, except one is green and the other is blue.
Another connection is with Geostigma and Aki Ross' disease. Dr. Aki Ross was infected by phantom particles that were lethal to her. The Phantom Particles also gave her visions of the Phantom planet.
In FF7, Geostigma was caused by contact with Lifestream infected by Jenova cells. The people infected by Jenova Cells were controlled by Sephirot's will. Sephiroth's plan was to have enough infected people dead, that is, sent to the lifestream, so he could control it, thus controlling the planet. He wanted to take the infected Lifestream he controlled to other planets and attack them, like Jenova did.
Both Geostigma and the disease Aki Ross had are caused by trace amounts of the invading spirit. Sephiroth planned to use Jenova's alien spirit to do the same as what the Phantom Gaia wanted to do: take over the planet's lifestream. Sephiroth's plan was similar to Jenova's plan which was in turn similar to Phantom Gaia's desires.
Sephiroth's means of travelling to other planets was probably using Omega. Assuming a connection exists, in Spirits Within the Leonid Meteor that brought the Phantom Gaia was Omega. And based on that, Jenova as well was an Omega. If Sephiroth could control the Lifestream and Omega, perhaps so too could Jenova.
Jenova was probably something like Sephiroth: a person that managed to control the Lifestream. The Phantom Gaia on the other hand was an unguided manifestation of Lifestream, it never had an entity controlling it, that's why it just attacked things at random. It did not act like Jenova did, with an aimed intent. Jenova attacked the Cetra manipulating their emotions appearing as their loved ones, clearly showing that Jenova had some sort of intelligence.
As explained by Bugenhagen, the Lifestream contained not only the life of a planet, but also its memories. The Phantom particles infecting Aki showed her memories of the Alien Gaia. The Jenova cells and Sephiroth's will also had a power to get inside people's head, but unlike the Alien Gaia, it was under someone's control, and so instead of showing random visions it managed to manipulate its targets.
It is not only Sephiroth or Jenova (supposedly) that had the power of controlling Lifestream. Aeris too was capable of doing that, as she had a power similar to Sephiroth's of existing after death through her will.
FFVII and FFXIIIEdit
Fal'Cie are gods that picks up humans to do what they can't do. If they don't, they're cursed and become monsters.
Based on that fact, we all know that Sephiroth is NOT evil. He has been manipulated. He's wielding Masamune, a sword that can only be held by pure hearts (Citation needed for this). Now let's put all this together. Jenova is a goddess, she fell from the sky, and when Sephiroth gets in contact with her, he became evil. Sephiroth: -I'm the chosen one
-Cloud' you're nothing but a puppet
(i need the exact citation here) But does that make you think of something ? Jenova may be a Fal'Cie who took Sephiroth as a L'Cie. She wasn't able to destroy/control the Planet, so she took someone who could.
Barthandelus says he needs a sacrifice big enough to call the Maker to recreate a new-world (The Promised Land ???) Maybe that's what Jenova was trying to do too. Now it's evident that the fall of Cocoon is an allusion to the Meteor fall of FF7. Barthandelus himself says that when Orphan will be destroy Cocoon will crash on Pulse, exactly like the meteor of FF7. Jenova try to do exactly the same thing as Barthandelus. Now the question is which one happened first.
Perhaps the events of FFXIII occurred first, seeing as how the world nearly ends at the end of FFXIII-2 with a man-made Cocoon flying in the air. Presuming that the world shakes free of the rift it lays in at the end, the man-made Cocoon, Bhunivelze, might have been flattened into what becomes the Midgar plate, over Academia, which becomes Midgar.
All FF games connected through Eidolons Edit
With some effort it is possible to see how the nature of Eidolons through out the games connects. Maybe Square has tried to develop some consistency on how to portray Eidolons and have left some subtle hints on the nature of Eidolons in different games or used the depiction of Eidolons in previous FFs to inspire how more recent games used Eidolons.
So, here is the theory: Eidolons exist in their own world and are a mix of some primal magic energy and a recently deceased mortal creature. This magic energy is basically the soul or the essence of the Eidolon and it needs a body to reincarnate and become complete. This magic energy may be used by itself, without ever being incarnated into a body, but in this state it isn't a full Eidolon and it isn't a true living creature. The Eidolon's soul doesn't have an identity or personality, it only becomes an individual when it is fused with a body. This can happen naturally, by accident or it can be man made.
Now I'll explain how this could make sense based on what happens in FF games.
In VI it is said that Eidolons were created when people died in the battles between the Warring Triad, in IX it is said that they manifest themselves based on myths people have and how they imagine them to be.
In IV, the Eidolons have both a human and a "true" form, the same happens in X. The Eidolons in X are created by the dreaming of people who gave their life energy to create Aeons. The Aeons can manifest themselves in a specific human form or in their true form.
So here is where the connections begin.
The "magic power" part of the equation, the Eidolon's soul, would be created from human myths and memories. It is like if enough people believed in a specific entity, the essence of this entity would exist. This essence would then borrow the body of a living creature that recently died and become a full Eidolon, which is a creature capable of thinking and is infused with magical power.
Now is where I try to explain how the idea for the origins of an Eidolon's essence comes from. First, we have to assume that Memoria from IX and the Interdimensonal Rift from V are the same place. They are very similar in both games, as they are a universe that exists between different universes, connecting them.
In IX we see that Memoria connects the real world with the Crystal World, where lies the main crystal from where everything come fron. In V we see that the Rift connects the real world with the Void, the Void being the exact opposite of the Crystal World. The Rift/Memoria exist between universes and is a path to where the most primitive forces of the universe reside.
We also see that Memoria and Rift is shaped based on the locations the party visited. Both Memoria and the Rift would be planes that are created solely by memories, imagination, thoughts. They are like a physical manifestation of the collective minds of all living things, those that visit Memoria/Rift will walk through areas that are directly connected to their memories.
So the same mental energy from humans that creates the Rift/Memoria would also be the same mental energy that is capable of creating the essence of Eidolons.
Basically, the idea is that humans can unconsciously create magical things. A single human in FF is capable of defying reality with magic, making fire or ice appear out of nowhere for an instance, this is a conscious effort that comes from the power humans have to use magic. But an individual can also accidentally use magic or tap into magic powers in situations of extreme emotions, as seen in several FF games.
This natural tendency to conduct magic would allow several humans to unconsciously shape reality, creating powerful magic that manifests itself in an entire realm (like Memoria/Rift) or in the essence of summons (as explained in IX). This same ability can also be used consciously by a collective of humans and create enormously powerful things (as shown in X). Basically, throughout FF games humans, humanoids and living things in general have displayed the ability to use magic naturally, though this power can be lost depending on the way humans live.
So this is where the essence of the Eidolon comes from, but like I said before, the essence would be just raw power that doesn't posses an identity. This raw power can be manipulated and used as a tool. This is shown to happen explicitly in VII and IX.
The part where this essence somehow needs a body to exist as an individual comes from VI and X. In X the Aeons are created when several people give their life energy to dream an Aeon. The Aeon still retains a human form though, and can transform to their true form (like in IV). The part where they are created from the energy of people dreaming an Aeon is similar to the explanation from IX, that says that Eidolons come from human myth and imagination. So it could be that the human form maintained by the Aeon in X is the individual that hosts the essence, the essence which is crafted by the people who give their life energy to dream it.
In VI, the people that died caught in the crossfire between the Warring Triad possibly served as hosts for Eidolon's essence. The Warring Triad had extreme magic powers and it could be that those who were killed by these powers ended up accidentally fused with them. The powers used by the Warring Triad could be just the pure essence of the magic energy that creates Eidolons.
So in X and VI we see the process of Eidolons being created with death of a living creature and magic energy.
Also, we actually see Phoenix as a summon being created this way in three different games. When Lenna's Dragon dies in FFV, it turns into Phoenix. In FFVI, Locke finds the Phoenix Magicite and uses it to revive Rachel, the Magicite shatters, she comes back to life and right before dieing again, she says "Phoenix be reborn" and from her body Phoenix is recreated. In VII, when the Condor at Fort Condor dies, Phoenix appears and you get the Phoenix materia.
Based on all of these games we can see how a full Eidolon may be created. It could be accidental (VI) as a result of the exchange of extreme magic power or could happen naturally (V, VI, VII), possibly the result of an affinity of the Eidolon's soul with the individual that died (V, VI, VII all involve sacrifice and rebirth from the part of the deceased).
The thing is though, that summons haven't always appeared the same way. In some games they exist not as individuals but just as a crystal or something else. In VI it is shown that when Eidolons die, Magicite can be created. In VII, summon materias can be manufactured or form naturally.
So my guess would be that summon materias and magicites would be just this raw magical power that isn't a complete individual, when you use them you just summon the energy that can be used to create a new summon. That would make sense according to the lore of both games: the Eidolons leave behind part of their soul in crystal form in VI and in VII the materia comes from magic energy of the living, the same kind of energy I theorized to be responsible for creating Memoria and the Eidolon's essence.
Also interesting to note is that the Eidolons in VI died but came back to life. We see Shiva and Ifrit dieing and leaving their magicites behind, but later we see them attacking the empire. That shows that the magicite hosting the Eidolon's power can exist at the same time that the Eidolon is alive. Possible that the magicite only carries part of an Eidolon's magic essence.
An Eidolon would be able to exist as an individual living in their own land or visiting the real world, and would be able to borrow their power to a mortal, while at the same time that an Eidolon's essence can be summoned just from a crystal that has this essence.
For this idea to make sense, we should also accept that to summon an Eidolon's power one might not need to have in hand the raw magic power of the Eidolon. So here's how I think is how it works in each game, based on my theory:
In III and V, summon spells be acquired from the Eidolons themselves or bought, however to use this power you need to have been blessed by one of the crystals. You need to have magic power infused to you to make use of their powers.
In IV, the Eidolons themselves lend their powers to mortals, but just the ones that have a natural affinity for this (summoners). So when you summon Bahamut, you are actually using the real one's powers, not just Bahamut's raw essence.
In VI and VII, you can only use Eidolons if you have a shard containing their raw power. In both these games, non-magical people can use the raw power but they need to carry an artifact that holds this power.
In VIII, you don't need to be magical or have been blessed with magic, but you need to have the Eidolons themselves lending you their power. However, you can only use it through junction. Junctioning requires mental energy from the host (which causes them to lose memories), but it doesn't require the host to be die nor does it require the raw energy of an Eidolon to be used. I'd say a junction is an incomplete process of creating Eidolons, one that doesn't cause a full Eidolon but doesn't require neither the host nor the Eidolon to have died.
In IX, Eidolons can be used either with magical gems that houses their raw power or by those with an affinity to summon them (the summoners).
In X, Eidolons are artificially created, in a way that forces the natural process of an Eidolon's birth (mental/life energy + dead person). I'd say that the Aeons in FFX are not true Eidolons, but rather man made Eidolons created when humans managed to collectively use their magic powers.
In XII, I think there aren't any true Eidolons. The Espers in the game are artificially created by the Occuria, through which process is never made clear.
In XIII, I believe that fal'Cie aren't true Eidolons. They are probably artificial Eidolons created by the Maker. The Maker might've used the raw power of an Eidolon in the form of a magicite and fused it to an artificial body. This body might just perform a series of pre-programmed tasks (like Carbuncle) or it might have been given an artificial intelligence (like Barthandelus).
This theory I worked is also the basis of my current project to make a Final Fantasy fan game based on the Eidolons, you can check it on my talk page. --Cid of the Lufaine 18:40, April 5, 2011 (UTC)
- Interesting but I don't think it really fits in with the topic on hand which is the connections between Final Fantasy games. The only thing that really connects Final Fantasy games through summons is the fact that they have summons, as you said even the nature of them changes drastically between games. Interesting theory but it might be better suited to another forum, I think anyway, Oni Dark Link 18:57, April 5, 2011 (UTC)
- You got a point I guess, I didn't really connect all universes, just explained that might have some coherence to how Eidolons work. Though, from this theory we could reach the conclusion that all FF universes are connected through the Interdimensional Rift/Memoria. Maybe the Farplane is a manifestation of Memoria, maybe the promised land of the Cetra was the Land of the Espers, I dunno it would take some stretching to connect things. --Cid of the Lufaine 23:24, April 5, 2011 (UTC)
