In the very beginning, there's a great bit in Link's very room: if you search around a bit, you'll discover a few wooden carvings — a few in-progress meaning he is, in fact, making them. Now, what is Skyward Sword's core gimmick? Motion-controlled swordplay. In other words, precision cutting. No wonder he's not only the only Link to actually use this (as Twilight!Link's was pure waggle) but he's so gifted in his hobby.
Zelda explains that Link had to meet so many challenges in order to power up his sword in order to prove he is worthy of the Triforce. Why? Two hints:
Zelda mentions that it was to show that Link possessed all three virtues of power, wisdom, and courage, while the Silent Realms were also designed to test each virtue.
Link is repeatedly stated to possess an "unbreakable spirit".
The purpose of testing Link like that was to ensure he had power, wisdom, and courage in balance, so that when he claimed the Triforce it wouldn't break into three parts like when Ganon took it in Ocarina of Time.
Unlike most other Zelda games involving time travel, you will never see all of the past version of the Lanayru region; therefore, you'll always be wondering what all the ancient structures looked like and how the inhabitants lived, thus adding to the desolate mood and atmosphere of this region. Well played, Nintendo.
His appearance resembles a fencing outfit (minus the mask), and he wields a rapier in his second phase. What could be more appropriate for a sword-to-sword duel?
Some players might be expecting a huge ancient robot as the boss of the 3rd dungeon had they not seen spoilers, only to ultimately be disappointed when it turns out it's the Giant Scorpion of the E3 2010 demo. However, remember all those little Arachas that plague the dungeon? Yeah, they must have a mommy.
If you Enemy Scan an Aracha, Fi tells you it's a larva that has a 1000-year life cycle and is constantly growing, which should clue you in to the idea that there's a giant one around somewhere.
Not only a mommy, but a daddy, too, which explains the other Moldarach you find in the shipyard.
During the first battle to reseal the Imprisoned, you are told by the old woman who watches over the Sealed Temple if The Imprisoned escapes, it would mean The End of the World as We Know It. At first, you think it is because it is incredibly strong anyways and probably has enough power to level Hyrule, but after turning Fi into the Master Sword, these battles are given an even greater importance because a) The Imprisoned requires the Goddess Hylia's soul to regain its true form as Demise, b) Zelda is in fact Hylia reborn as a mortal, c) Zelda has put herself into a crystallized sleep capsule in order to maintain the seal for as long as she can, and d) said capsule is in the Sealed Temple — not far from where The Imprisoned's seal is located. Meaning if you cannot stop The Imprisoned from reaching the top, you've just allowed him to regain his true form.
Hyrule's desert used to be a vast ocean. In the alternate world of Termina, the Gerudo are pirates!
When Link powers up the Goddess Sword into the Master Sword, the game states that now only Link can use the sword. In the later games, they say that only those with a pure heart can use the Master Sword. What makes this brilliant is that it makes perfect sense; since only those who share Link's soul or destiny are able to wield the Master Sword, and Link has a pure heart and is generally good, with time, people assumed that only those with a pure heart could use it, not knowing the true reason, exactly how information tends to get warped over time. This makes it Fridge Brilliance for all the Zelda games. It also handily explains how Ghirahim was able to snatch it during your first fight with him — and why he doesn't try to grab it during the third fight with him.
Dungeons and Temples:
One of the main questions plaguing the Zelda series concerns the dungeons and temples. Why are they there? Why are they so convoluted and hard? Some actually serve or used to serve a practical purpose, but others are just... there. This game explains several dungeons and various other trials by saying the Goddess left them for the Chosen Hero. Little more than a Hand Wave... until you find out Zelda is the human incarnation of the aforementioned Goddess. She set up those trials SPECIFICALLY to be difficult and convoluted — to force Link to become courageous, powerful, and wise enough to use the full power of the Triforce. She even shed her immortal form and allowed herself to be born as a human in his time, to befriend him and give him the motivation to undertake the trials. The entire Zelda series is arguably a massive, ongoing plan by the Goddess Hylia to ensure that there is always a Hero strong enough to use the Triforce against evil. THAT, ladies and gentlemen, is why it is the Legend of Zelda. In other words, the temples are a collective architectural Stealth Mentor, designed to train Link to be strong enough to beat the Big Bad of whatever game they appear in.
This also explains why the Goddess Sword wasn't able to activate the Gate of Time. Considering it was made by Hylia, you'd assume it'd be strong enough to activate it. Hylia PURPOSELY made the Goddess Sword not able to activate the gate so Link would have to get the sacred flames, and thus become stronger.
In other games, it seems odd that any weapon could harm someone wielding the Triforce of Power. Now we know why the Master Sword can harm Ganon; it's empowered by qualities of all three values. The fact that it's a "blade of evil's bane" is even a manifestation of Power itself! Its name really does fit. More than that, once you go back to the past and see Zelda before she goes into her long slumber, she uses the power of the goddess Hylia to further empower the Master Sword. Thus, the True Master Sword has all three values, plus the blessing of a fourth goddess. It may not be much, but it's clearly enough to tip the balance out of Ganon's favor.
This game was known to detail the origins of the Master Sword long before the game was released. But why was it named the Master Sword? This version of Link was the one who unlocked the hidden potential within the Goddess Sword, thus creating the Master Sword in the first place. Fi is the living spirit of the Goddess Sword. What does she call Link, the one who wields the sword? She calls Link her "master". The name "Master Sword" is a reference to the original owner of the blade. The very first "Master" of the sword is Link himself, thus making the "Master Sword" HIS sword! As shown by the ending, Fi treasured her time with Link despite it just being her purpose. It is brilliant (and also heartwarming) to see that the spirit within the sword named it after her very first companion. It is also a play on words. Assuming Fi is the one to introduce the next protectors to the sword, what would she call it? Master's Sword, which sounds exactly like...?
It's well known that the Ballad of the Goddess is Zelda's Lullaby backwards; The Ballad of the Goddess backwards is, therefore, the goddess's lullaby.
It gets better. It's been joked that since it's backwards, the Ballad must be for waking up Zelda. Which is exactly what Link is tasked with doing late in the game.
The first time Zelda's Lullaby plays in this game is when Zelda actually puts herself in a long sleep, making it the first time Zelda's Lullaby has been used as an actual lullaby.
In the secondLegend of Zelda game, an ancient legend states that the first princess to bear the name "Zelda" put herself into a long slumber. What does Zelda do in Skyward Sword? Exactly that.
The reason Link starts with six hearts instead of three like in all the other games? Unlike most of his descendants, this Link went through basic combat training at the Knight's Academy, which buffed up his endurance.
Many parts in the game appear to be useless (like a part in the Sealed Grounds that has a fence over it that serves no purpose). It is later revealed. however, that these parts are meant to be used when you upgrade your equipment or for the story to progress. Like in the Sealed Grounds, that annoying fence was removed by Groose to build his rails for the Groosenator.
Beedle complaining that Link is heavy. He may not seem to weigh much, but keep in mind he's carrying a sword, a shield, and all of his gear (yes, even the bugs and treasures). Adding all that up can make someone weigh a lot too.
Notice how Link can't traverse between the three sub-sections without resorting to his Loftwing or Groose's catapult later on, but certain other species can. They include Gorons and Mogmas, who are experts at travelling over mountains and digging tunnels, respectively. So, they're disconnected by extremely high mountains, possibly created by the dark forces who invaded the past Hyrule.
When Link's gear gets taken from him after Eldin Volcano erupts, the Master Sword is the only part of Link's arsenal that isn't in a treasure chest somewhere. Why? Because by then, it's the fully-powered Blade of Evil's Bane. The bokoblins probably couldn't even touch it, much less try to take it. In Twilight Princess, the Master Sword is explicitly described as "a sacred blade that evil can never touch," not only confirming the above but also explaining why Ghirahim doesn't use his signature Bare-Handed Blade Block the third time Link fights him.
A possible early indication that The Imprisoned is actually Demise, the game's final boss: all of the game's bosses have Boss Subtitles, except for both The Imprisoned and Demise - just like how Ganon was subtitle-less in Ocarina of Time, in contrast to the rest of that game's bosses.
A pretty silly one: Fi is your sword. The game uses Wii MotionPlus to have 1:1 (-ish) sword motion — in other words, your Wiimote is your sword. Therefore, Fi is your Wiimote, and therefore she doesn't actuallybreak the fourth wall when she tells you your batteries are low — they're HER batteries!
Fi's singing expression (and some of her other mannerisms) tend to be considered Uncanny Valley territory by the fanbase. But this makes perfect sense when you consider that she is, essentially, a goddess-supplied helper-bot created for the sole purpose of aiding the hero and has had (to the best of our knowledge) next to no human contact prior to Link. To this troper, that makes her heartfelt farewell even more of a Crowning Moment of Heartwarming.
A minor thing that came to mind, about the shields. Now, one may wonder, with how, for example, why the imagery of the shields Link can procure in this game don't appear in any other game, save for the Hylian Shieldof +1 Infinity. The answer to this is simple; all the other shields break. It is only logical that, after so long, the other shields wore down over time, leaving only the Hylian Shield as a reminder of that ancient era.
Perhaps it also explains why all of the Hylian Shields don't really look all the same, too. In The Legend of Zelda: Ocarina of Time, the Hylian shield looks different than this one, adding an upside down triangular yellow piece at the bottom. Maybe the shield creators just used the design of this game's shield and based theirs off of it, due to the fact that it's one of the only remaining shields from this era.
At the beginning of the game, a big deal was made about his Loftwing being red — apparently a rare color. In the games it appears in (Ocarina of Time, Wind Waker, Twilight Princess, Skyward Sword), the Hylian Shield always has a stylized red bird on it. In this game, all the shields have some kind of avian imagery: wings, claws, wings and claws — but the best shield, the Hylian Shield itself, has a whole red bird. With Skyward Sword as the earliest point in the Zelda timeline, it can be extrapolated that all the Hylian Shields have red birds because the original bearer had a red Loftwing.
Impa's dual appearance in this game is a reference to both of her portrayals throughout the series; the old woman represents Impa as she appeared in (the manuals of) Zelda I and II, while the sleek, younger Impa hearkens back to her appearance in Ocarina of Time.
On the main page, there's an example of Gameplay and Story Segregation that notes that right before the final boss battle, which takes place in the past, you're given the opportunity to return to the present to prepare, and everything is the same. However, the state of the world at this point could easily be interpreted to mean that Demise is destined to be defeated, so there's no chance that the future you return to could be a different one. Indeed, all of the Gate of Time-exclusive pieces of time travel seem to point at a Stable Time Loop, so the future would be predetermined.
The Amber Relics found all over the place are chunks of Zelda's sarcophagus.
All the structures and enemies in the past version of Lanayru Desert have this red-and-blue abstract pattern on certain segments. A similar red-and-blue motif can be found in Gerudo-related designs, though the Past-Lanayru patterns are typically gaudier than the more faded, deserty Gerudo patterns. This signifies how the Gerudo probably came across relics of the past (such as the robots or buildings) and decided to incorporate elements of those designs into their own. Cross-reference an Armos◊ with Ganondorf◊.
That symbol on the base of the Goddess Statue (the one that turns into the entry to the inside of the statue) and the Goddess Crests look like Fi.
The depowered Master Sword in Wind Waker is identical to the half-powered Master Sword in Skyward Sword. Zelda also prays at the Earth and Sky temples. In Wind Waker you power up the Master Sword with the prayers of the Earth and Wind sages.
Faron Province is associated with Farore, the Goddess of Courage. The dungeons of Faron are also where you find the vast majority of the game's undead creatures, which are pretty scary, and which require courage to face.
The introduction of Loftwings: The Herald of Hyrule is a bird◊. Now we know where it comes from. Even better when one notices that the crest of Hyrule on the Hylian shield has the bird in question colored Crimson, making it match the Loftwing that was bonded to Link.
Faron Province is associated with Farore and courage, Eldin with Din and power, and Lanayru with Nayru and wisdom — it's in the names. The native residents of each province lack these virtues: kikwi lack courage, mogma lack power, and the ancient robots lack wisdom.
The citizens of Skyloft have relatively small ears compared to the future residents of Hyrule in games such as Ocarina of Time (when Hylians are the most prominent race), and also lack any special magical abilities. Their origins are not touched upon, other than that their descendants inhabited the surface AKA Hyrule. The Hylians, however, are said to be descended from the gods, have magic-infused blood, and can hear messages from the gods. Who's the only resident of Skyloft with long, pointed ears that are comparable to that of the future Hylians? Who also obviously has magic in her blood and could hear the surface (arguably the gods) calling her? Zelda, the mortal incarnation of Hylia. She's the one who would have eventually given birth to the first Hylians. The way all other Skyloftians were designed compared to Zelda is pretty genius, if one thinks about it.
Zelda is the mortal incarnation of Hylia. Hylians. Think about it. (Compare "Skyloftians" as the previous race).
When you first meet Gorko, he gives a fanciful description of Skyloft, such as it having buildings made of gold. However, he also mentions water that grants immortality, giant disease-curing fruit, and pumpkins that never rot. Well, the pumpkins DON'T rot, you have to find water from a sacred spring to heal Faron, and the Tree of Life does indeed bear a (gigantic) fruit that you use to cure Lanayru. Although, the sacred spring and the Tree of Life are technically on the surface, so they don't count.
The two springs where Zelda has to purify herself are located, respectively, in the Skyview Temple and the Earth Temple. Why? They symbolize her descent from the sky to the earth, and the celestial being Hylia reincarnating into an earthly being.
In the final temple (and maybe this was stupid obvious), you have to fight the ultimate symbol of fear — the undead — and overcome them to get the Triforce of Courage. You also have to show the ability to manipulate primal forces (well, the flow of lava anyway) to get the Triforce of Power, and bypass tricky things for the Triforce of Wisdom. So you have to show mastery over each of the virtues of the Triforce before you can be allowed to obtain them.
The Sky Keep's ideal layout — that which gets him all the pieces of the Triforce in quick succession — has Wisdom coming last. Link has to rearrange the temple like a sliding block puzzle in order to get to them all. Think about that for a second. There was no series of tricky puzzles to overcome — the temple itself is one giant puzzle, and solving it all proved that Link was truly worthy to claim that last piece.
The fact that this Link is right-handed unlike the rest actually makes sense. Unlike every other Link, the Link of Skyward Sword was trained in a structured school. Since left-handedness is generally stigmatized, sometimes to the point of forced-conversion, they probably taught him to fight right-handed — and since Link is canonically ambidextrous in all incarnations, he probably never even thought twice about it. He's definitely ambidextrous here — while he wields his sword righty, he wields the bow like a lefty. Word Of God is he just has different preferences for the different weapons.
According to the timeline released by Nintendo, this is the oldest game in the series (in-universe), followed by the second-oldest game in-universe, the Minish Cap for the Gameboy Advance. In Minish Cap, there is an entire civilization and set of temples that exist above the clouds. Perhaps the remnants of the civilization from Skyward Sword?
Of the three Sacred Flames, Nayru's Flame is the only one that doesn't increase your sword's attack power. Instead, it increases your ability to gather information — appropriate for the Goddess of Wisdom.
In previous games, Nayru tended to be associated with water, but in this game her element is electricity instead. Despite that, the boss guarding Nayru's Flame is a one-eyed sea monster with tentacles, just like the bosses of the water temples of Ocarina of Time and Twilight Princess.
As you progress through the story, stronger mooks pop up. At first, this was put to the game just making things harder as the player gains experience. But when it is revealed Demise's seal is weakening, it means that his power is flowing into the mooks and making them stronger.
Demise and divinity:
Why does Demise decide to reincarnate himself as a mortal in all the other games? Because Hylia did it so well in this game and he figured he'd give it a try too.
Related, because the Master Sword "absorbs the remains of Demise's consciousness" or something like that in order to seal it away; whenever Link slashes Ganon/dorf in other games, he's really smacking him with himself.
And in addition, it's explicitly stated in-game that the Gods created the Triforce with the quirk that their kind could never use it. However, Demise is known to covet it: this being the reason he warred with the mortals and was sealed away in the first place. This might seem to lend itself to Fridge Logic at first. Demise is the Demon King — essentially a God of Evil — so why would he bother seeking it if he could never use it? It's entirely possible that Demise did not know this at the time and when he found out, he decided that the best way to go about getting it was to follow Hylia's example and reincarnate himself as a mortal. He LET you win because it gives him the means to acquire it once he is reborn as the mortal Ganondorf!
Zelda/Hylia states that the reason she was reborn as Zelda was to ensure that Link would have an emotional connection to her, and thus would be willing to face any danger and surmount any obstacle that threatened to harm his beloved friend. This is the only game where we get any real interaction with Zelda, especially before the excitement begins. The designers were ensuring that we spent time getting to know this shy bubbly girl before she is dragged into danger because it allows us the players to have that same connection to her, as evidenced by the fact that we were willing to see this game through to the end to save her.
All the instructors at Skyloft are named after birds. All except Zelda's father Gaepora, that is, because he's instead named after Kaepora Gaebora, the owl from Ocarina of Time.
The Imprisoned is destroyed in the present, but Demise is killed in the past. Plus, the Sealing Spike is nowhere to be seen in the past. How was The Imprisoned still in the present, and how did he escape when he was supposedly destroyed? Simple. The Imprisoned was the remains of Demise's energy that were trapped in the Master Sword that escaped, and since only Link can wield the Master Sword, they had to seal it away a different way. Since Demise has a new form every time he appears (hence his changing forms as The Imprisoned), that fits in line with Fi's description that Demise appears different to everyone who confronts him.
At the end of the game, it's revealed that Ganondorf is an avatar of Demise, while Zelda is an avatar of Hylia. That leaves Link as apparently a mere mortal. Or is he? He's someone's avatar... yours. The "Link" from our world to theirs.
Groose's character development from jerk to a pretty competent dueteragonist has some great foreshadowing: his outfit (and hair) is mostly made of the primary colors red, blue, and yellow, a scheme normally reserved for heroes.
Fi at the end:
When Fi thanks Link at the end of the game and hopes they'll meet in another lifetime, what do you suppose happened? What other character do we all know just like Fi? Navi! That's right — when Fi expressed her gratitude, Hylia realized that Fi, her creation, had become more than just a machine, and deserved more than an eternity in a sword! Reincarnation is a major theme of the game; it makes sense that Hylia would put her agent, Fi, in a place of such massive instability — namely, the period of time during which Ocarina of Time took place. That particular game was responsible for splitting the timeline into three pieces; Hylia sent Fi as Navi to help Link of the future! Who better to help a legendary hero than Fi, who already knew the legendary hero? It also helps that both Navi and Fi have similar sounding names, serve the same purpose in both games, and are both rather annoying when you ignore them.
Even better...After he's defeated, Demise ordains that while he may die, his hatred for the gods is so mighty and powerful that it will live on, manifesting as one (and possibly more, it's up to you) of the hero's greatest enemies in the future. Fi tells Link before she's sealed in sleep that although their journey together has ended, being able to look back on it in her final moments has left her with her first feelings of happiness, feelings she'll be able to dwell on long after she's faded away. We know such a feeling would inherently have to be especially strong if it managed to be instilled in a being who was never programmed to feel, to comprehend the human spirit, like Fi claimed. Maybe those happy feelings and memories of the time she spent guiding... protecting.. .being with Link, manifested themselves, as the demon king's hatred did, as the companions he'd be paired with in his future incarnations, and were responsible for bringing all of them together... Navi, Tatl, the King of Red Lions, Midna, Ciela, and even Princess Zelda herself.
At the end of Link to the Past, we're told that the Master Sword sleeps again. Fi is always in the sword, just silent from that point on, maybe keeping the other spirit in the sword at bay?
Judging by the positions of the dead robots and bokoblin skeletons you see in the Lanayru Desert, it seems that whatever burned out the region happened FAST. It could be a result of the Dragon Lanayru dying.
When you approach the bones of the Dragon Lanayru and "examine" them, there is still a faint light in his eyes. He says, when you heal him, that he has "eternal life." What if that means that a shred of him still survived, imprisoned in a dead and powerless body for the whole time up until Link finds him?
The subterranean area of Ancient Cistern was a mild case of Fridge Horror — after all, there have been plenty of creepy dungeons throughout the years. But think about it — the Hindu imagery, the golden light colors, the lotus blooms — it's pretty much Heaven. And what's downstairs from Heaven? That's right. Link just went into a zombie-infested, blood-watered Hell.
The main mooks in the hell section are zombie bokoblins. Who probably killed them in the first place? You did.
Just why does Koloktos giggle like a child when you kill it? Considering that it runs on souls, it could easily have been powered with the souls of children.
This gets far worse if you know that Nintendo actually based this place on The Spider's Thread, an old Japanese story about a condemned murderer and rapist who was offered one more chance at freedom by Bhudda... by climbing a spider's thread out of hell. Yes, that part in the game is based off this story. Not only that, but in the story, the other souls who are damned to Hell try climbing out along with this criminal, only for the criminal to shake the rope and for everyone else to fall back into the pits of hell. ...Sound familiar? But what pushes this over the edge is that, yes, the Bokoblins are based on the "damned souls" from this story, the lower level is based on hell and the upper level is based on heaven... but also, in the story, it's said that Hell is filled with rivers of blood. ....Think about what the lower level looks like in the game... and let the horror sink it...
Skipper, like all of the little robots in the desert, is only alive in the past. And Skipper proved the robots are actually aware that they are in a future where they and everything they worked for has decayed and been forgotten. They may be robots, but they're sentient and have personalities. You'd think that'd create some sort of existential dread.
Additionally, after Link defeats Tentalus, Skipper and his crew are now in power of the ship again. However, we find out earlier that Skipper has a wife and child living in Skipper's Retreat. (This can be assumed by reading the pieces of paper on the walls of Skipper's Retreat — one of which is a note from his child. There are two deactivated robots in the Retreat — we can assume they are his family). Skipper has revealed that he cannot access his old home (which is why Link has to get the sea chart for him). Skipper may forever live in Lanayru's golden age, with his crew, protecting the Flame... but his wife and child are deactivated for eternity.
Which, in turn, is why their main industrial activity seems to be centered around gathering Timeshift Stones, which allow them to live forever at their height in Lanayru's golden age.
Before his second fight, Ghirahim makes a speech about a "thread of fate" binding him and Link to do battle, and that he intends it to be "stained crimson with [Link's] blood." Creepy enough, but takes on anothermeaning if you're familiar with a certain Asian proverb. It says a lot about Ghirahim that this isn't the most blatant pass he makes at Link.
Demise and the Sealed Temple:
You know how if The Imprisoned gets to the top of the Sealed Temple, you get a Non Standard Game Over? Well... it's because Zelda / Hylia is in there, locked in a thousand-year sleep, and completely defenseless. And you have no idea she's there the first couple of times you fight him. It's very chilling to look through that crack in the door and realize how close you kept coming to losing her forever.
And it's even more creepy to think about it from her point of view. You're sleeping, sealed in a crystal, when this huge... thing is there to kill you, and you're defenseless. Presumably so, since Hylia is in mortal form at that point. She's pretty much screwed if The Imprisoned reaches her. No— EVERYTHING is pretty much screwed if The Imprisoned reaches her.
Most scary is that this outcome is not simply imaginary, or a threat; it really happens in the game if you fail to stop the Imprisoned from reaching the Temple, where it will devour the helpless Zelda and absorb her soul.
The scene before the second Ghirahim fight in the fire sanctuary, Ghirahim dives down towards Link, lands in front of him, and then suddenly appears behind him. Most would probably assume that he just teleported as usual, but if you look at the scene again, you'll realize that there was no distinctive teleporting sound or animation. Looking at the scene carefully, it looks very much like that Ghirahim actually DOVE underneath Link's legs to get behind him. No wonder the guy looks terrified...
In the opening cutscene introducing Skyloft, we see the crimson Loftwing later revealed to be Link's. As the scene continues, you see Groose and his gang jump onto their Loftwings, trailing down your own. That's right, this is the scene where he kidnaps your bird.
When Demise curses the successors of Link and Zelda, it obviously affects a third party, Impa. What if it affected Groose in the most extreme way by latching Demise's spirit on to his, creating what would be reborn as Ganondorf and later Ganon? It has always been shown that Ganon is a bit arrogant to a fault, but Demise never displays any of that in his time against Link. Groose, however, is shown to be entitled, wanting to control and lead things with attitudes fitting a certain King of Evil, that ultimately led to his downfall. This means that every time you beat Ganon, you were doing it with the inadvertent help of Groose's corrupted spirit, and you've techincally been fighting and killing the reincarnation of Groose, making this scene way more powerful. Groose does look like he could be the original ancestor of the Gerudos. He's tall and red-haired. So this would mean that Demise cursed Groose as well, turning his bloodline into one of the most hated in Hyrule's history, leading to a slow, but sure extinction. Ugh, poor guy.
Potions are improved by adding bugs to them. Think about that every time Link gulps down his Heart++ potion, which is upgraded via the Eldin Roller — a dung beetle.
When Ghiraham becomes Demise's sword, the similarities to the Master Sword are obvious. It's easy to assume that Ghiraham is a twisted copy of Fi. However, Ghiraham was Demise's sword since before the sealing. Fi was created after. Fi is a copy of Ghiraham.
