Crystal (term)



Crystals (クリスタル) are legendary and often elemental stones and objects that have appeared in every game in the main Final Fantasy series. Even in games where they are not a central plot point, there has been at least some reference to them. Crystals have power over natural phenomena, and function as a powerful source of magical energy. Many antagonists focus their efforts on seizing the Crystals to gain power towards their goal.

In most games there are typically four Crystals: a Water Crystal, a Fire Crystal, a Wind Crystal, and an Earth Crystal. On occasion Crystals may be aligned with Darkness. Crystals may often be found in Crystal Rooms in early games. The Crystals are often treasured for their power and many myths and legends surround the true extent of their abilities. Uncovering the truth of these myths and their meaning is a typical part of any Final Fantasy game.

The concept of four elemental crystals that sustain the world that occurred in early Final Fantasy games likely derives from the. These five elements are, in ascending order of power, Earth, Water, Fire, Wind, and Void. The element of Void is not represented as a crystal, but may have taken the form of The Void, a dimension that connects the different Final Fantasy worlds.

Final Fantasy
The original Final Fantasy is where the crystals originated. They were initially known as "Orbs" in the North American localization, due to a truncated Japanese-to-English translation.

The Warriors of Light begin the game already in possession of four elemental Crystals, and each of the Four Fiends guards a larger, power-drained crystal of his or her own element, which the Warriors restore after defeating the Fiend. Garland possesses a fifth "Dark Crystal" as well, though its significance is not elaborated upon. When the Warriors of Light restore the light to all four Crystals, they channel their energy into the fifth Crystal, allowing them to travel to the past in order to stop the time loop.

Final Fantasy II
A Crystal Rod is a key item that unlocks entrance to the Tower of Mysidia, where the ultimate magic Ultima is sealed. Atop the tower are four crystal orbs that represent each element. When examined, they increase the party's stats once each. In the center of the room where the crystals lay is a fifth that contains the Ultima Tome that teaches Ultima.

In the Dawn of Souls bonus dungeon, Soul of Rebirth, the Crystals grant Minwu access to the Ultima Tome in Machanon.

Final Fantasy III
Final Fantasy III has eight Crystals. Xande is trying to drain the Crystals of their power in order to create an imbalance between light and darkness. He manages to drain the Crystals on the ground continent, covering it in darkness and freezing time. He is, however, unable to drain the ones on the floating continent. Eventually, the forces of darkness manage to drain the other two Crystals, creating an imbalance that summons the Cloud of Darkness. The Wind Crystal chooses four children to go out and restore the balance, and give the Crystals back their power.

After the four youths find each Crystal, they are given new Job Classes. Once the youths are given the powers of the four Crystals of light, they enter the World of Darkness and must defeat the four guardians of the Dark Crystals to obtain the aid of the Warriors of Darkness. They then use the four Crystals of Darkness to make the Cloud of Darkness vulnerable.

Another crystal is found in Goldor Manor, but it is a crystal made of pure gold as with everything Goldor owns. The Light Warriors initially suspect this gold crystal is the Crystal of Earth, but are mistaken, and the gold crystal is shown to have no special powers.

Final Fantasy IV
Final Fantasy IV has eight primary Crystals. The four elemental Crystals form the "Light Crystals", and are kept in the Overworld. The Crystal of Water is in Mysidia, the Crystal of Fire is in Damcyan, the Crystal of Wind is in Fabul, and the Crystal of Earth is in Troia.

However, there are also four "Dark Crystals" kept in the Underworld. The location of two of these Crystals is never revealed, but one is kept by the Dwarves in their castle, and one is found in the Sealed Cave.

If all eight Crystals are gathered in the Tower of Babil, it has been told that the "way to the Moon" would open. However, gathering the Crystals would actually summon the Giant of Babil, a wish-granting giant. The Lunarian Zemus wanted to have the Giant destroy the Earth so the Lunarians could settle there, and he used Golbez to do so. Many more Crystals are revealed later in the game, such as the eight Crystals of the Moon and a Crystal that appears in the battle with Zeromus.

The Crystals of the Moon are sentient and are responsible for sealing Zemus's power for the time being. The Crystal that appears in the battle against Zemus is an item said to make Zeromus vulnerable. Golbez tried to use it on Zeromus; however, only those born out of the Light can use the Crystal. When Cecil Harvey used it, Zeromus became vulnerable, and Cecil and his friends defeated it.

There is also the Crystal of Flight, which rests within the Lunar Whale, and is used to transport the heroes to the Moon and back. The Elder of Mysidia implies that Crystals power the Lunar Whale, and in the Nintendo DS release several Crystals can be seen embedded in parts of the airship.

In the game's Nintendo DS release each of the eight Crystals are colored differently. In the SNES and Game Boy Advance releases, the Crystals were colored light blue or dark red/black, depending on their alignment to Light or Darkness.

Final Fantasy IV -Interlude-
Three crystals makes an appearance in the sequel to Final Fantasy IV, and all three of them are silently shedding their lights within their Crystal Chambers. The three crystals are the Fire Crystal in Damcyan, the Wind Crystal of Fabul, and the Dark Crystal inside the Sealed Cave.

Final Fantasy IV: The After Years
The Mysterious Girl and Kain? band together to collect the eight Crystals of the Blue Planet, all of which have returned to their original resting spots since the events of Final Fantasy IV. The girl also returns to the Red Moon and drains the power of their Crystals, shattering them.

In the depths of the True Moon, numerous Crystals appear and shatter, reviving various bosses from Final Fantasy IV to attack the party as they travel deeper into the moon's surface. In the Moon's final chambers the party recovers the eight Crystals of the Blue Planet, and in the final battle with the Creator, they are used to render him vulnerable to the party's attacks.

Final Fantasy V
Final Fantasy V has four Crystals that control the elements in the First World, and without them, the wind would not blow, the oceans would dry, the fire would burn out, and the life of the earth would be destroyed. The Wind Crystal was kept in the Wind Shrine which was maintained by Tycoon, the Water Crystal was kept in the Walse Tower and maintained by Walse, the Fire Crystal was kept in Karnak, and the Earth Crystal was located in the Ronka Ruins. Long ago, the Warriors of Dawn used the power of the Crystals to seal Exdeath within the Earth.

At the dawn of the adventure, a man named Cid Previa invented a machine with the power to amplify the Crystals' output. However, if the Crystals were allowed to operate at this capacity, they would shatter. Cid deeply regretted creating the machine. At the same time, Exdeath was trying to shatter the Crystals himself so he could become free. However, the Crystals all eventually shatter, and each shard becomes the source for a new Job Class for the characters.

In the Second World, the Crystals are replaced by the Crystals who guard the Great Forest of Moore.

In the Third World, the party battles Exdeath inside the Void. After this, they are able to recreate the Crystals with the power of the two generations of Warriors of Dawn, thus regenerating the world.

Final Fantasy: Legend of the Crystals
Before the story begins, Ra Devil's forces have already stolen the crystals of Earth, Fire, and Water. Sensing that something is amiss, Linaly's grandfather sends her to check on the Wind Crystal. The spirit of Mid Previa had been residing in this crystal, and decided to use Linaly's body to hide the crystal from Ra Devil's forces.

But Linaly is eventually captured, and later rescued by Prettz, Valkus, and Rouge. It is at this time that the other three crystals are reclaimed as well, but not before Ra Devil had already transformed himself using their power.

Final Fantasy VI
When an Esper dies, their remains crystallize into Magicite, which appear as glowing shards of green crystal. In contrast to magic extracted from live Espers via Magitek, magic can be taught naturally and at a much higher potency using Magicite.

Using Magicite, the protagonists are able to use magic and fight the Gestahlian Empire on its own terms for a time, before the Empire is decimated by Espers. At this time the Empire abandons Magitek in favor of Magicite in preparation to invade the Esper homeworld and seize the Warring Triad. After Kefka revives the Warring Triad and absorbs all of their powers, he becomes the source of all magic in the world. Thus, upon his defeat, Espers, Magicite, and magic disappear from the world entirely.

Final Fantasy VII
The crystallized form of Mako is known as Materia, and a subtle nod to the crystals of past. The Materia allow the user to control magic spells, summons, gives boosts to statistics and adds extra commands. Two exceptionally powerful Materia pieces are the White Materia and Black Materia. Sephiroth seeks the Black Materia to summon Meteor to strike the planet, while Aeris tries to stop him by using the White Materia to summon Holy, which is the only thing that can destroy Meteor.

There are also four extremely rare Materia found in caves: Knights of the Round, Mimic, HP <--> MP, and Quadra Magic, which are said to be so powerful due to being in secluded areas, and have been given a large amount of time to grow and collect. In addition, there are the four Huge Materia, colors red, blue, yellow, and green. Three of the four Huge Materia also correspond to matching color Materia: Master Summon, Master Command, and Master Magic can be acquired from the red, yellow, and green Huge Materia if the player has mastered all Materia shards of that type.

Crisis Core -Final Fantasy VII-
During the first battle with him at the Nibelheim Mako Reactor, Sephiroth can summon four colored crystals to assist him in the battle. The crystals are identical in appearance to the four Huge Materia from Final Fantasy VII.

In a locked chamber in the Banora Underground the player can enter battle with Green Materia, Red Materia, Yellow Materia, and Blue Materia. They cast elemental magic in battle and their coloring corresponds to four of the five typical Materia colors.

Final Fantasy VIII
The only prominent crystal is the Crystal Pillar, a gigantic crystal believed to have originated from the Moon. The monsters in the world come from the moon, and the crystal is responsible for summoning them to the planet by creating a strong energy field. It reacts to a certain location on the planet, and this reaction creates a signal that directs the Lunar Cry towards that location. Thus, in Final Fantasy VIII, the Crystal acts as a malevolent force.

Final Fantasy IX
In Final Fantasy IX Crystals are the source of all life; the Crystals residing at the center of planets circulate life, from which all life is born, and to which the souls return upon death, and as the memories of living beings accumulate inside the Crystals, the planets grow. Eidolons in Gaia are guardian spirits created by the Crystal in order to protect it.

The people of Terra had mastered the art of fusing their Crystal with others, allowing them to assimilate other worlds and keep their race thriving even when their current Crystal weakened. As revealed in the Final Fantasy 20th Anniversary Ultimania, once a Crystal has aged, it returns to the cosmos and becomes the source of a new Crystal.

Crystals also appear in the game as a means of summoning Eidolons. The four "jewels" sought by Queen Brahne of Alexandria were in fact fragments of a Crystal broken apart 500 years prior to the game. If all four jewels would come together in Alexandria, Alexander would be summoned. This echoes Final Fantasy IV, as Alexander heavily resembles the Giant of Babil, which was also summoned by a gathering of Crystals.

Also, Crystals can be equipped as Add-ons, which grant the user special abilities, particularly for Dagger and Eiko, who can learn Summon Magic from them. Eiko can also alter her Summon Magic according to the gemstone she has equipped.

Final Fantasy X
Spheres are round crystalline objects used for various purposes in the world of Spira. While they are not like materia or even crystal shaped, they contain various magical energies possibly provided by the pyreflies embedded in them, allowing them to act as keys, contain memories, and even record events that can be viewed like a movie. They also, symbolically, represent the game's theme of cycles.

Just prior to the series of final boss fights, Tidus and company are warped to a bizarre spinning room called "Sin - The Nucleus." Within the Nucleus, Tidus must avoid crystal spikes while grabbing ten glowing, teleporting crystals, each of which bestows either powerful spheres or weapons. Once all ten items are acquired, the player is teleported to Dream's End for the final battle.

A larger crystal also makes a cameo in Luca. There is a statue in the round square where a huge clear crystal is sitting. As the player walks closer, the camera focuses on the crystal. The Crystal Cup can also be classified as a cameo for the crystal, and it can be seen handed to the Besaid Aurochs by Wakka if the player wins the first Blitzball tournament of the storyline.

Also in Final Fantasy X, when the Magus Sisters perform Delta Attack, they surround the enemy party in eight crystals, four of blue hue, and four of red-orange hue. This is a reference back to Final Fantasy IV, where there were four blue Crystals of the surface world, and four red-orange Crystals of the Underground.

Final Fantasy X-2
In Final Fantasy X-2, dresspheres allow one to use the memories within the sphere to unleash associated powers.

Synthesis Crystals
Crystals are common and are used in item synthesis, sometimes found when players kills enemies with the status effects Signet, Sanction, or Sigil active. There is a crystal for every element.

Players can also give crystals to gate guards of their nation to aid in that nation's development. In return, players are rewarded with Rank Points, which are sometimes needed to receive new missions from the player's nation.

There are 8 main types of crystals, with each element corresponding to a different crafting task, and each can be found at the Auction House under the category "Crystals":
 * Fire Crystal - Burning or Heating.
 * Earth Crystal - Bonding.
 * Water Crystal - Diluting, Dissolving, or Liquifying.
 * Wind Crystal - Carving or Cutting.
 * Ice Crystal - Freezing or Congealing.
 * Lightning Crystal - Disintegrating or De-synthesizing.
 * Light Crystal - Mending, Repairing, or Blessing.
 * Dark Crystal - Decaying or Aging.

Protocrystals
Six "Protocrystals" serve as gateways to the six sleeping gods, Shiva, Ramuh, Ifrit, Leviathan, Titan, and Garuda.

The protocrystals are located in the following areas:
 * Cloister of Flames in Ifrit's Cauldron.
 * Cloister of Frost in Fei'Yin.
 * Cloister of Gales in Cape Teriggan.
 * Cloister of Storms in The Boyahda Tree.
 * Cloister of Tides in the Den of Rancor.
 * Cloister of Tremors in the Quicksand Caves.

Telepoints and Gate Crystals
In modern-day Vana'diel, six telepoints exist in the forms of crystals. In the Shadowreign era, three additional telepoints existed that have since been destroyed. When a player first examines a telepoint, they receive a gate crystal, a key item needed to be teleported to that specific telepoint via teleport and recall spells.

The following are the locations and teleport spells associated with each telepoint: Existing telepoints in present-day Vana'diel:
 * La Theine Plateau - Teleport-Holla
 * Tahrongi Canyon - Teleport-Mea
 * Konschtat Highlands - Teleport-Dem
 * Eastern Altepa Desert - Teleport-Altep
 * Yhoator Jungle - Teleport-Yhoat
 * Xarcabard - Teleport-Vahzl

Destroyed telepoints:
 * Jugner Forest (S) - Recall-Jugner
 * Meriphataud Mountains (S) - Recall-Meriph
 * Pashhow Marshlands (S) - Recall-Pashh

Magicite
Magicite are unusual crystal deposits found in beastmen strongholds near destroyed portions of the Crystal Lines, large conduits that connect the Crags of Holla, Mea, and Dem.

Mothercrystals
Yet another type of crystal are the Mothercrystals; five shards of the original that is said to have created the gods, which was shattered into the five pieces to fend away the Emptiness.

Orbs
Orbs also make an appearance in Final Fantasy XI as rare, exotic gems that, when cast into Burning Circles in certain areas, grant access to Burning Circle Notorious Monster fights. Orbs are sold by Shami in Port Jeuno, but he only accepts payments in the forms of Beastman's Seals or Kindred's Seals.

The Seed Crystal
An ancient crystal plays a key plot role in Final Fantasy XI: A Crystalline Prophecy - Ode of Life Bestowing.

Final Fantasy XII
Crystals are commonly found in the form of magicite. One of their many functions is as a Save Point. These Crystals are divided into Save Crystals, which let the player save the game, and Gate Crystals, which also allow teleportation to other Gate Crystals. Many enemies later in the game also drop various elemental crystals, used for making items in the Bazaar. Espers are also bound to Crystals before they are defeated.

There is also an enemy that takes the form of a crystal, called a Crystalbug. There are only three Crystalbugs in the entire game.

The game's story focuses on nethicite, both manufacted and deifacted. Items such as the Dawn Shard are revealed to be related to the Sun-Cryst, which is essentially a crystal on its own. There is a location in the game that is a giant crystal known as the Great Crystal, where the Occuria dwell.

Final Fantasy XII: Revenant Wings
Crystals in Revenant Wings come in the form of auracite, which people can use to summon Yarhi (the game's version of Espers). However, using the auracite comes with the price: Each time someone uses it, their anima slowly drains away. This is the reason the aegyl have been reduced to emotionless shells in the beginning of the game.

There are also larger pieces of crystals called Auraliths from which all auracite comes. Destroying the Auraliths releases the trapped anima they have absorbed. In addition, there is the Soul Crystal gameplay element that appears in certain battles and reincarnates its team's KOed members periodically.

Fortress
Crystal-like objects appear in Fortress concepts and come in eight different (apparently elemental) types. It is currently unknown whether these objects are nethicite, auracite, Auralith, or something else entirely.

Final Fantasy XIII
Crystals are central to the plot of Final Fantasy XIII, interacting in the world in the form of fal'Cie, god-like machines powered by the crystals. Their power seems limitless as they helped create Cocoon, which is essentially another moon of the world of Gran Pulse. Fal'Cie are capable of creating l'Cie by planting a crystal shard, known as an Eidolith, somewhere inside the human body; the l'Cie are, to a degree, their avatars in the world.

L'Cie can use magic and summon Eidolons through the use of their Eidoliths. Furthermore, if the l'Cie fail in the task they are given, the power of the crystals will turn them into a monstrous crystallized Cie'th. If they manage to complete their Focus, l'Cie are rewarded with eternity by becoming lifeless crystals. Because both fates are considered to be a fate akin to (or even worse than) death, Cocoon citizens live in fear of the l'Cie and cast out those who become as such.

Humans, like the fal'Cie, also possess crystal power, though in a different manner. Like in many other games in the series, crystal seems to be the Final Fantasy XIII's universe's life substance. The crystals power the fal'Cie like a computer's processor, giving them amazing magical powers and making them immortal, incapable of aging, yet the humans possess an even greater power; when a human dies, their "soul" turns into crystal energy and passes through the Door of Souls "to the other side", something akin to a concept of heaven. The fal'Cie envy this trait as they, too, would like to pass through the Door of Souls to the other side, to be reunited with their Maker. During the game's final chapters the party can observe the crystal energy in the air as tiny glimmering shards.

Final Fantasy XIII-2
When Noel and Serah defeat a monster in battle, they can gain its power in form of crystal which they can use to summon enemy in next battle to fight alongside them. This is an ability granted to Serah by the goddess Etro. Mog has a crystal on his antenna instead of the classic moogle pompom; it is also incorporated into weapons he turns into.

Fragments, crystallized memories of sorts, take appearance of various crystals, and artefacts, items which do not belong in their time period, are also a type of crystal. Caius's greatsword and armor has a crystal attached to it, which is revealed by one of the Fragments to be Bahamut's eidolith.

The meteor that Noel arrives to New Bodhum in is also a crystal in actuality.

Atlas is powered by a type of crystal.

The Historia Crux apparently utilizes crystal as a means of preserving the states of locations that have previously been visited, as completed locations bear the message "Time and memory, frozen in crystal".

Final Fantasy XIV
Aetheryte crystals and are massive shards of crystallized aetheric mist, precisely cut and fused to arcane machinery. Their origins unknown, they are used by the present cultures as means of teleportation.

Like in Final Fantasy XI, elemental crystals and shards can also be gathered for usage in item synthesis. Also can be obtained are crystals drained of their elemental aspect, which are called deaspected crystals.

The location Mor Dhona is littered with naturally-occurring crystals, as opposed to the enshrined gems seen elsewhere in the game. Crystals as scenery are a common element in final or significant areas for much of the series.

Final Fantasy Tactics
Crystals may appear when a defeated unit remains unconscious for three rounds (300 CT). They represent the condensed soul energy of the defeated unit. Living units may pick up these crystals to fully restore their HP and MP. If a human unit picks up the crystal formed from another human's soul, the living unit may choose instead to learn the abilities that the defeated unit had learned, at no JP cost. Once a unit's soul condenses into a crystal, its body disappears, and it cannot be revived by any means, making the transformation into a crystal a form of Permanent Death.

The crystals of defeated human units are based on their color palette. Ramza's units (palette 00) have the teal-gray colored crystal, the Order of the Northern Sky units (palette 01) have the bright blue colored crystal, the Order of the Southern Sky units (palette 02) have the red colored crystal, the Corpse Brigade units (palette 03) have the yellow colored crystal, and the Church of Glabados units (palette 04) have the purplish-gray colored crystal.

In Midlight's Deep, each blackout area can be lit slightly by an unclaimed crystal. The area will be completely revealed when there are totally five crystals remaining.

Additionally, the twelve Zodiac Stones are crystalline stones of great power, fulfilling this game's role of Crystals. There is also a hidden thirteenth Zodiac Stone obtained from Elidibus on the tenth floor of Midlight's Deep. This stone represents Serpentarius the Serpent, but is simply an add to the original twelve.

Final Fantasy Tactics Advance
The five crystals in Tactics Advance are the threads that bind together the dream Ivalice, made by the palace, and each one represents one of the races of Ivalice. Crystals exists in special folds in space, called "seams". As the crystal's magic is beneficial to all Ivalice, special means are being employed to protect them. This was once known in a theory, one of the believers are Montblanc. This was then confirmed when the clan had to fight with the first guardian of the crystals, also known as Totema, Famfrit.

Marche's quest in the game is to shatter the five crystals in order to return home. In order to do this, he must defeat the Totema that guards each crystal. A sixth crystal is actually Queen Remedi, the Li-Grim in her true form, and even when they are all destroyed it takes the will of all of those from the old world to allow them to return.

The classic four crystals of Fire, Water, Wind, and Earth appear in a group of optional subquests, known as "sigils". On these missions, each sigil must be obtained by defeating a "Falgabird" of the corresponding element: Marilith (Fire), Lich (Earth), Kraken (Water), and Tiamat (Wind). These Falgabirds are a reference to the original Four Fiends. Once the four sigils are obtained, two further missions can be completed to craft the Mind Ceffyl and the Body Ceffyl from them.

Final Fantasy Tactics A2: Grimoire of the Rift
Crystals appear in certain quests/battles. When touched, the crystals allow the character to be transported to a different battle field. Touching the crystals is usually required to complete missions they appear in.

Crystal Defenders
In Crystal Defenders, the player defends crystals from numerous waves of enemies. In addition, there are Power Crystals, which raise the abilities of nearby units.

Final Fantasy Versus XIII
It is vaguely established that crystals act as a source of political and magical power to major nations in Final Fantasy Versus XIII. Several kingdoms used to have their own Crystals, but lost them through warfare. One Crystal remains in one kingdom, however, and Noctis is sent to protect it from other kingdoms' forces trying to obtain it.

Final Fantasy Type-0
A crystal is located in each Peristylium of Orience, bestowing unto the nation a special blessing and power to its citizens. They also act as a means of political power as well, giving their people the power to rule over their lands with a means of protection from invasion. In return however, crystals erase the personal memories associated with those that die and perish in life amongst those that remember their existence.


 * From the Dominion of Rubrum of Suzaku, their crystal bestows upon them the Power of Magic, allowing the bestowed to use magical spells and powers that bend nature's phenomena at their will. The Rubrum Peristylium Suzaku refines the use of magic through academics and training of individuals skilled or potent in magic capability.
 * From the Milites Empire of Byakko, their crystal bestows upon them the Power of Weapons, its power allowing all people to interact with it freely through crafting arsenals and technology utilizing its energy. The Byakko Peristylium researches Byakko's properties, having derived Magitek Armor and all sorts of innovations for its use.
 * From the Lorican Alliance of Genbu, their crystal bestows the Power of the Shield, allowing its people to draw its magic to grant them great strength and robustness greater than other countries.
 * From the Kingdom of Concordia of Sōryū, their crystal bestows the Power of the Dragon, allowing its people to communicate and interact with monsters peacefully in everyday life.
 * Amongst all nations, crystals can brand individuals as l'Cie, giving them a crucial task known as a Focus for them to achieve. To achieve this, l'Cie are also given special powers and immortality, but at the risk of the expenditure of memories, spirit, and identity over the many years spent as a l'Cie.

At the beginning of High Commander Cid's expansion of the Milites Empire, it seems that his country has found a new weapon to jam other nations' crystals, and sends his l'Cie army and airships to dominate Orience.

Final Fantasy Crystal Chronicles
Large Crystals can be found in every town and village in the Crystal Chronicles world. They protect people from the poisonous mist known as Miasma, that plagues the entire world. The effect is only temporary, and after a year each town and village must send out Crystal Caravans to collect three drops of Myrrh. To collect the Myrrh, the Caravanners use a Crystal Chalice, which not only can hold the Myrrh but can protect the travelers from Miasma with its crystal for a short range.

A Carbuncle in Mag Mell reveals that all the crystals protecting each village and city were originally part of a once Great Crystal that was shattered after being struck by a meteor that brought with it the Meteor Parasite which spread the Miasma.

Final Fantasy Crystal Chronicles: Ring of Fates
Crystals in Ring of Fates are an item for everyday life. Chelinka was born with a special crystal in her hand that she can only use when her twin brother Yuri is around.

The Great Crystal is also seen, and it holds the memories of the world. It is later revealed that use of the crystals alter the path of reality and destiny. When the crystals are used by the moontouched Lunites they turn crimson, whereas the crystals are normally blue.

Gameplay-wise, crystals found in towns and dungeons heal party members fully and also act as a save-point and checkpoint.

Final Fantasy Crystal Chronicles: My Life as a King
In Padarak, a Crystal that appears within the Kingdom grants King Leo the power of Architek that allows him to rebuild his fathers Kingdom. To build new buildings, a type of crystals known as elementites must be collected by Adventures in dungeons. These elementites were once part of the main antagonist, the Dark Lord.

Final Fantasy Crystal Chronicles: Echoes of Time
Originally Crystals were used to keep the air clean and bestow prosperity on the land, like in Ring of Fates. When an inventor, Larkeicus, created machines that would allow the people to live a life of luxury (and for himself, immortality), Crystals were harvested as energy sources. As time passed, the crystals disappeared and the people became desperate for more, digging mines to uncover them.

One day, a large Crystal, the world's last remaining Crystal Core, appeared in a small Village. Larkeicus located the last Crystal using his ring, while also searching around the globe for a new source of Crystals. The inventor found Sherlotta in the Forest after killing the rest of the villagers. When the Crystal appeared in a forest pond, it infused itself to Sherlotta's soul creating, presumably, a starsinger. Larkeicus could not take the Crystal, even though there was no one to stop him. The Crystal Core was a sort of negative Crystal, rendering Larkeicus's machines useless and sending his dynasty into ruins.

A thousand years later, Larkeicus realizes the Crystals disappeared because of the shock waves from the future, and prepares to stop the event from happening. When he activates the ruins, the Crystal Core shatters and is later repaired by the hero. In the game's final events the Crystal Core is summoned to create the disturbance that made the Crystals disappear two millenia ago.

The hero is forced to shatter the Crystal, and both Larkeicus and Sherlotta disappear in a blinding light. When arriving home, the hero throws the Crystal shard received from Sherlotta on his/her sixteenth birthday into the Crystal's pool. The next day, the once tiny Crystal begins to grow into one like the Crystal Core that appeared 2000 years ago.

Final Fantasy Crystal Chronicles: The Crystal Bearers
There are four Tribal Crystals, each representing a race, that form the "Crystal Principle", an ideal form of balance in the world. However, during the Crystal War, the Lilty destroyed the Yuke's Tribal Crystal, dooming the race to a place between Existence and Oblivion. The crystal shards were created from the Yuke's Crystal and served as a power source. The Crystal Idols gather these shards to recreate the Yuke's Crystal.

Final Fantasy Mystic Quest
There are five Crystals in Mystic Quest, each having their power drained by one of the Vile Four. Flamerus Rex drains the Crystal of Earth's power, rendering Level Forest and Foresta a decaying wasteland and turning most of the residents, including children, into old men and women. The Ice Golem's uses the Crystal of Water sends the Aquaria area into a permanent winter, the Dualhead Hydra causes earthquakes to become rampant around Fireburg using the Crystal of Fire, and Pazuzu causes violent windstorms using the Crystal of Wind.

In addition to these four crystals, the Crystal of Light appears to Benjamin as an old man offering cryptic advice. The Crystal of Light in turn may have been under the dark influences of the Dark King, as it later shines at his throne when he is killed.

Final Fantasy Dimensions
The crystals in Final Fantasy Dimensions choose people to become Warriors of Light.

Dissidia Final Fantasy
There are ten Crystals, each one representing one of the first ten games of the series. Each Crystal is somehow reflective of its original game or its representative character, such as Cloud's Crystal being a piece of a Materia, Zidane's Crystal being the Crystal featured in Final Fantasy IX's logo, and Tidus's Crystal being a Sphere.

These Crystals, later revealed to hold a tenth of Cosmos's power, had to be obtained by its respective Warrior of Cosmos by asserting their true desires to fight for what they believe in. To this end their respective enemies challenge their beliefs, wishing to speed along the manifestation of the Crystals as part of a plot to destroy Cosmos. When all ten Crystals have been recovered, the player can access the final stage and confront the final boss, Chaos. After he is defeated, the Warriors of Cosmos each depart back to their own world, taking their Crystal with them.

The Emperor is stated to possess several Dark Crystals as a result of Jecht, being a former Warrior of Cosmos, manifesting them but with their allegiance being to Chaos since he was brought to the side of discord. These Dark Crystals are not seen in-game, although it is known that with their power, The Emperor could survive the destruction of The World and rule it after the Gods killed each other.

The manikins that serve as the basic foes of Dissidia also appear to be living creatures made entirely of crystal.

Also, the Crystal from Final Fantasy V makes a cameo as a tutor from the in-game manuals.

Dissidia 012 Final Fantasy
In Dissidia 012 Final Fantasy the player witnesses Cosmos granting her power to her warriors, telling them that after they fight enough battles this power will manifest as a Crystal. It is also during this cycle that the Emperor arranges for Jecht to become a Warrior of Chaos to manifest the Dark Crystals.

The Reports, which go into detail on the backstory for Dissidia's world, explain that the manikins are living crystal ore recovered from The Void that shapeshift to take on the forms of others.

Theatrhythm Final Fantasy
The Music Crystal is the source of music and harmony in the world, existing in the space between Cosmos and Chaos called Rhythm. When the forces of chaos disrupt the Music Crystal's energy, the heroes embark on a journey to energize it with Rhythmia and restore its light.

The player can also collect crystal shards by playing Dark Notes and reaching certain Rhythmia milestones. Obtaining eight crystal shards of the same color will unlock a new character.

Final Fantasy Fables: Chocobo Tales
Five Crystals appear in this game, connected to different elements and guarded by different Summon Creatures. The Red Crystal sitting atop the volcano Mt. Magma has power over Fire, and is protected by Phoenix. The Green Crystal of Earth rests in the forest, under Unicorn's watchful eye. The Blue Crystal hidden in the underwater shrine controls Water, and has Leviathan as its guardian. The Yellow Crystal stationed at the highest floor of the Technolith is aligned with the power of Light, and is under Ramuh's care. The final crystal, the Black Crystal, was created by Bebuzzu to bolster the powers of darkness and chaos by feeding off of the negativity within the hearts of living creatures.

Irma uses this crystal to drain the others and then feeds the energy to Bebuzzu, who in turn is transformed by each power. At the end of the game, he uses the fully powered Black Crystal to travel to the world of darkness as he tries to revert the universe to its original form - The Void. A backstory for the Crystals is given in the story Legend of the Crystals.
