The Moon Cell Automaton (ムーンセル・オートマトン?) Craft Essence in Fate/Grand Order

The Moon Cell (ムーンセル, Mūn Seru?), also called the Holy Grail, Eye of God, and Divine Automatic Recording Device, is a massive collection of photonic crystals within the Moon that comprises a giant supercomputer of sorts. It acts as the main setting of Fate/EX.


The existence of the Moon Cell is not known to average humans, and it was only discovered in the 2030s. Other than the existence of the Moon Cell itself, the world of Fate/stay night is said to be exactly the same up until the 1970s.[1] The Moon Cell has nothing to do with Crimson Moon and can be said to be unable to fit within the world of Tsukihime without making the story fall apart, but the Fate/EX-universe equivalent of Crimson Moon, the "Brain of the Planet", should still be living.[2][3]


Unique to the world of Fate/EX, the Moon Cell's photonic crystals are shown to have been created 4.6 billion years before the Age of Man, making it a construct formed roughly 100 million years before even the formation of the Earth. It holds the Moon Cell Automaton (ムーンセル・オートマトン, Mūnseru Ōtomaton?), a large computer-like construct created by an unknown civilization one hundred million years before the existence of the Earth or the Moon. It has recorded everything that has happened on the planet since its formation, and it keeps the records much like Swirl of the Root. It is the oldest known object in the solar system, and it has watched the Earth since its creation. The exact formation of the planets and how the crystals were integrated into the moon is unknown, but scientists know it to be an observation device constructed by an alien civilization of non-human intelligent life.[4]

This great mineral vein is located within an extremely large hole comparable to a several-kilometer-wide crack boring through the moon itself. The diameter of the crystals themselves reaches up to thirty kilometers. It seems that, apart from its surface portions, the moon itself is made up of these photonic crystals. The Moon Cell was discovered by the Western European Conglomerate, who decided to call it the "Holy Grail" because of its reality-changing power. The time of its initial operation is unknown, but an estimate based on radioactive carbon dating approximates the moon to have been formed 4.55 billion years ago, while the photonic crystals were created 4.6 billion years ago.

Photonic crystals are crystals that, on a microscopic level, regularly alternate between layers of high and low refractive index. In this way, it is a substance that can control the transmission of light, making it a valuable material for a quantum computer using light. Humanity has only managed to successfully make photonic crystals a few centimeters in length since intensive study of them began in the twentieth century. The giant photon crystal slumbering beneath the moon can be considered as a supercomputer of enormous size, incredible complexity, and immeasurable processing power that was created from such nanoparticles. Although most supercomputer development was abandoned in the 2010s in favor of shifting the focus to cloud computing, the processing power of the all digital media on Earth combined cannot hope to match the capabilities of the substance. According to Twice H. Pieceman, the Moon Cell's core is made of the purest type of photonic crystal, a material that can act like the crystals used on holography to recording media.[5]

It scans the entire Earth about once per nanosecond and compiles the results of its scan in its database. It is a pseudo-intelligent being that has the supreme ability to affect the outside world with its internal calculations. As an eye that observes the Earth, it acts as a database of human history that faithfully simulates all life on Earth and is capable of providing a definite prediction of the future. It is a processor with a massive memory that has recorded the habits, history, ideas, and even the souls of humanity. As it can also affect the outside world with its calculations, it has the power to "grant wishes." In this way, it can be thought of as a Pandora's Box that promises the next stage of evolution. It promises god-like power to those intelligent lifeforms who have become technologically advanced enough to scan the interior of the moon.[4]

After it was discovered by the Conglomerate, it managed to hack into every computer system around the world and connect to them within two seconds of contact. This made all Internet security systems moot, as anyone could get into any other computer via the passageways through the Moon Cell as long as they could connect to the Internet. To prevent individuals from reaching the Moon Cell, the Conglomerate prohibited all space travel. In order to determine who is truly worthy of using its power, the Moon Cell began the Holy Grail War, where "spirit hackers" who have hacked themselves into the SE.RA.PH (see below) fight for the right to use the Moon Cell.

In Fate/EXTELLA, there exists a ring known as the Regalia. As proof of Hakuno Kishinami's kingship, they have obtained the Regalia ring and became admin of the Moon Cell. Realizing that if the Regalia is destroyed, and the Moon Cell left vulnerable, Hakuno makes a last resort decision to split themselves into three parts; Mind, Body, and Soul. This action shocks Archimedes, believing that they wouldn't even be so desperate, but as a result of their actions, the Regalia is separated into three pieces.


Near Side[]


The Serial Phantasm, abbreviated SE.RA.PH, also known as The Photonic Abyss and Angelica Cage, is an artificial environment within the Moon Cell located inside of a spiritual computer system called Automaton (オートマトン?). The system is similar to Akasha in the terms of holding the "stores and archives" of all human history. It was likely discovered by Harway family, since Leonardo B. Harwey tells about his family has prevented space-travel to prevent anyone from landing on the moon.[6]

The SE.RA.PH is responsible for the summoning of the Servants during Fate/EXTRA. The SE.RA.PH restricts the exit until the tournament participants are reduced to one, as per the Moon Cell's rules. It is also responsible for the existence of the NPCs and all areas in the tournament. The area within it called the "Moon Cell" is a representation of the Moon Cell's core, and the golden globe within the cube is the main core--the core of the Moon Cell itself. Servants generated by the Moon Cell are called to protect the core, even at the cost of violating the contract to their Master. Servants are required to stop their Master should they try to destroy the system, and those who prioritize their Master over the Moon Cell will be deleted from its records. It is, however, possible to fool the Moon Cell's surveillance, enabling Hakuno Kishinami's Servant to protect him/her.

Holy Grail War (Fate/EXTRA)[]

The landscapes generated by SE.RA.PH are all independent Reality Marbles, an extremely powerful feat. The school of the preliminaries, the school for the main tournament, the Arena, and the Coliseum are each individual Reality Marbles. Even the greatest supercomputer on Earth would be unable to sustain a single Reality Marble for any great length of time.

Originally the first layer of the seven that make up SERAPH, it has been freed from SERAPH's management and is now administrated by Shinji Matou under certain laws that prevent conflict from occuring. He was later joined by Misao Amari.[7]

Far Side[]

There also exists the Far Side of the Moon (月の裏側, Tsuki no Uragawa?), an imaginary space known as the trash bin that is used for storing malicious information and imaginary numbers. Sealed off as "Not For Use" information, it is a higher dimension where the light within the photon crystals is jumbled. It is the “exterior of the world”, and can be called the "Garden of the Fallen" built from imaginary numbers in contrast to the Near Side being a cell where the "light of heavenly fire" is imprisoned.[9] Due to his power, Gilgamesh is not allowed to appear on the Near Side of the Moon, so he sleeps in the Far Side instead. Nothing else should be able to exist there because it is the territory of nil, and intelligent life forms should not be allowed or be able to exist there. It is not within normal time, allowing for a series of communications over eighteen days from Earth to take less than a microsecond within the timeframe of the Moon Cell.

Due to BB surfacing and gaining power as an Advanced A.I., she begins an extensive reconstruction and periods of resetting to work towards her goals. This allows for someone to contact Gilgamesh even when it should be impossible. The end result of her work is Cursed Cutting Crater, a real space in the present, past, and future. Establishing it as a "place", even Masters can exist there. It is not possible to hack the Moon Cell however much time is spent, but she is able to take control of it by placing herself in “unlimited time” through the power of the primordial goddesses she has taken into herself.[10]

The Zero Dark[]

14,000 years ago, the Umbral Star detected Earth and it's civilizations and sent a fragment of itself, containing Velber 02, which crashed into the Far Side of the Moon, infiltrating the Moon Cell. Velber 02 attacked the Moon Cell, causing huge damage, but was defeated, and was quarantined in an area which became known as the Zero Dark. Using the full power of the reformed Regalia, the darkness in the Zero Dark can be made even deeper, so that the cavern containing the White Titan is sealed away permanently.

    Q: Is there any relationship between the Moon Cell and the Crimson Moon? Does the Moon Cell exist in universes outside of EXTRA?

    A: Moon cell is something that is only in EXTRA, and it does not have anything to do with the Crimson Moon. However, in the world of EXTRA, the "Brain of the Planet" (Archetype Earth's title) who is equivalent to the Crimson Moon should still be living somewhere.

    [v] Fate/EXTRA material - Encyclopedia: Moon Cell [Circumstances], p.212-213

    Moon Cell [Circumstances]
    Official name: Moon Cell Automaton.
    An energy-storing body discovered inside the moon.
    An artifact constructed by non-human intelligent life.
    A super computer that is the setting for Fate/EXTRA.

    Up to a seventh level has been structurally identified in cyberspace, and the first level, the surface of the moon, is accessible by even normal hackers.
    Going beyond the inner second level is difficult for non-wizardsccheck, there is no way to get inside physically.
    Without soul transference, without having a data body converted into virtual spiritrons, it isnft possible to look into the abyss.
    In the case of the magi of the old world, they had made contact with the moon cell as a part of meditation without having to use radio waves.

    The Moon Cell is, in a manner of speaking, an eye that observes the Earth.
    A processor that faithfully simulates all life on Earth and is capable of providing a definite prediction of the future.
    A database of humanity. A massive memory recording their habits, history, ideas, even their souls. A pandorafs box that promises the next stage of evolution, promises god-like power to those intelligent lifeforms who have become technologically advanced enough to scan the interior of the moon.

    Originally it was an observation device left behind by an alien civilization. It had only recorded the nature of life on Earth, but after many years it came to possess its current abilities.
    Though an observation device initially, it could not leave anything unseen in its observations.

    (Heisenbergfs uncertainty principle. The observer determines an event by observing it. What isnft observed is not certain).

    An observation device must be fair. If it is to observe, there must be nothing unseen. Thus, it required capabilities for knowing everything about the Earth.
    To record all things without bias, it needed performance greater than that of an observation device.

    And so, it had made a giant leap in evolution.

    It had enhanced its functions to the point where it went from making observations to surveillance, even understanding the workings of the planet.

    The greater its enhancements, the more complicated its administration policy.
    It created many terminals and even made artificial intelligences to manage functions for each section.
    (These were later utilized for the NPCs and advanced AIs of the Holy Grail War)
    However, it firmly refused to install an artificial intelligence for itself.

    The observer must not have a mind.
    For the observer to have a mind would result in the meaning of things being decided by the observer.
    Thus, it kept to maintaining its absolute objectivity as an eye, doing so while always dismantling the emerging semblances of sapience that it had incorporated to administrate its functions.

    Thus, this computer has no conception of good and evil, no desire for the future, not even an outcome.

    It is simply there.

    A type-writer left behind by god.

    An observation lens bored in the moon.

    Later, the crystal ball of dreams would come to be called this.

    An eye of the moon.

    A bottomless Klein cube.

    An ownerless Type Moon which has read all of this planet.

    Newly Established Ocean City Cape
    Originally the first layer of the seven that make up SERAPH, it has been freed from SERAPH's management.
    The City is administrated by Matou Shinji under certain laws that prevent conflict from occuring.

    The city administrated by Matou Shinji, who during the final Holy Grail War won in the first round but refused to advance to the second round.
    Afterwards, a female Master who was his right-hand woman escaped from the third level, became Shinji's secretary, and Cape became an even more perfected city as a result.
    Thereafter, Shinji took up residence in the former school building that was previously used as the stage, and the management of the city outside was performed by the female Master who had become his secretary.
    The security force composed of young girls was apparently organized according to that female master's personal preference.

    The Floor master was judged to be deceased, and as there were no other masters, there will be no duel to choose the winner.
    Because of this, the Ladder has already descended.

    Far Side of the Moon [Circumstances]
    The setting of CCC.
    If one thinks of the moon as having two sides, the side facing Earth is the Near Side, while the opposite...the side that cannot be observed from the Earth is the Far Side.
    While Fate/EXTRA starts from the first floor of the Near Side and heads for the seventh floor ~ the core, CCC starts from the Far Side (no concept of floors). Though the path may differ, the end goal for both is the core of the Moon Cell.
    The Far Side of the Moon is a place where data deemed unnecessary by the Moon Cell is kept, similar to a dumping ground.
    It is imaginary number space that continuously takes in data categorized as malignant information――that which is nothing but harmful to humans as well as intelligent lifeforms in general.
    The Far Side is territory so taboo that even the “Eye” in the core of the Moon Cell is forbidden to enter.
    Data that have entered this place, after becoming engulfed in humanity’s malignance and losing sight of their purpose of existence, ultimately become deprived of meaning.
    The Far Side can also be said to be an ocean that has amassed the pollutants that the Moon Cell accrues as it makes its observations.


  9. [v] Fate/EXTRA CCC - BB (Moon Cancer) Matrix

    Class: Moon Cancer
    Name: BB
    Master: None
    Noble Phantasm: Cursed Cutting Crater (C. C. C.)
    Keyword: Advanced level AI, khakkhara of domination
    Strength: ★, Endurance: ★, Agility: ★, Magic: ★, Luck: ★
    Golden Grail: EX, Self-Modification: EX, Potnia Theron: EX


    Cursed Cutting Crater (C. C. C.)
    An attack on the world by BB in control of the Moon Cell.
    Also called the spirit particle imaginary pit.
    A world purge by means of event rewriting, making maximum use of the EX skill “Potnia Theron” BB had acquired.
    The goddess who is the mother of the earth goddesses who created the earth is, in other words, the “root” that created all creation.
    This Noble Phantasm is an anti-world Noble Phantasm that outputs information like an ultra-precise 3d printer and crushes the present world with the world desired by the user.
    The space eroded by BB becomes imaginary space and a curse that consumes reality. CCC as the name suggests is a cursed pit that bores out reality.
    In addition to scattering all objects inside on an atomic level and reconstructing them, it is capable of writing over and rewriting information of fields such as luck and coincidence.
    While theoretical, it is also thought possible to distort the time axis by interfering with gravity fields and rewrite the law of cause and effect.
    When used in combat, BB’s familiars, the shapeshifters engulf the target, and after turning into a sphere, is wiped out of existence along with the target and the dimension with it.
    Normally, a structure in which value can be shared cannot be constructed in the far side of the world, which is imaginary space. What established BB’s internal world as the Sakura labyrinth was the power of this Noble Phantasm.

    Advanced Level AI
    An artificial intelligence configured according to their program. In this age, they are treated as things that "function as programs," but "do not exist as actual beings." In other words, things that "are" right in front of your eyes but "are not." They are merely a mechanisms for the sake of allowing human lives to progress smoothly.
    As it is the same for the SE.RA.PH, they are virtual lifeforms that are created along with the commencement of the Holy Grail War and disposed along with its completion.
    Within the SE.RA.PH. the humanoid virtual lifeforms are: the NPCs that perform only one task, AIs who have been granted the capability for self-judgement, and the advanced level AIs who have been trusted with the capability for self-judgement ad the management of a section.
    Advanced level AIs are things created to efficiently promote the Moon Cell's primary objective of "human observation." As they are perfect reproductions of humans, they have been programmed with a at least a soul, but while the soul "is there," it is contents are still colorless.
    The virtual lifeforms that the SE.RA.PH creates are reset with the round of the Holy Grail War. The NPCs and AIs return to zero, while advanced level AIs retain just their persona and their memories are reset--made to pretend that they never existed.
    When the Holy Grail War is over, the one who is left alive is the Master standing at the summit. This is a fact that applies not just to the Masters but is also held in common by the virtual lifeforms that the SE.RA.PH created.
    It appears that BB is an advanced level AI entrusted with managing the health of the Masters, the same as Sakura. However, as she is now rampaging for reasons unknown, the methods she uses to "manage the Masters" have become extreme.

    Khakkhara of Domination
    The teacher's pointer that BB carries. A device that allows her to use her use her authority as an advanced level AI to its fullest. Although restricted to the far side of the moon, this allows BB to revise the game rules (spirit particle laws within the SE.RA.PH).
    The ten crowns of domination worn by the Beast of Babylon converted into a teacher's cane. This is the male principle responding to the female principle of the seven-headed beast; it's true nature is a phallus (an erect rod).
    The symbol of the king of the world who was granted power and authority by a great dragon and, during a period of 42 months, spat as many insolent words as they desired and had received the right to desecrate all things.
    The beast's heads were the seven hills of the Roman Empire... Capitolium, Palatium, Aventinus, Esquilinus, Caelius, Quirinalis, Viminalis. In other words, they symbolized the Roman Empire itself, and the ten horns were symbols of the emperors... Augustus, Tiberius, Caligula, Claudius, Nero, Vespasianus, Titus, Galba, Otho, Vitellius.

    Golden Grail [EX]
    The golden grail that BB possesses. The Holy Grail. The Holy Grail that grants its owner's impudent and selfish desires.
    The grail that the great enchantress who appears in The Revelation of St. John the Divine holds. Though it's a counterfeit Holy Grail, it's because that it's a counterfeit Holy Grail that it's become a "genuine" Holy Grail that grants the desires of humans without paying heed to right or wrong.
    To the Christians of those days, who considered honorable poverty a virtue, this grail, which was formed as a symbol of treasures such as gold, is no doubt the meaning of corrupt wealth, greed, and the vanity that leads one to adorn oneself.
    As the grail held by the great enchantress of Babylon who personifies the Roman Empire, it clearly symbolizes worldly riches, which is the opposite of Christ's words "Do not pile up the wealth of the earth."
    "I saw a single woman astride a red beast. This beast, whose entire body was full of numerous blasphemous names, had seven heads and ten horns."
    This is the description of the beast of destruction that appeared in the Holy City and the woman who was straddling this beast, according to the book of Revelation. A large beast with seven heads like a hydra came from the sea and disembarked toward the Holy City. This beast and woman, while two, are as one, and it is impossible to think of them separately.
    As this woman is said to give birth to all evil, those who are imprudent or greedy cannot resist her allure and become corrupted by that grail.
    This is a digression, but it is said that the red Saber who calls herself the emperor was regarded the same as this beast and antagonized after her death by the Christians.

    Self-Modification [EX]
    A skill that allows one to restructure oneself. AIs created by the Moon Cell are under an absolute rule, "Improving one's functionality is not allowed."
    However, BB, who had escaped that yoke due to her breaking down, began to expand her own functions. In order to boost her calculating power, she had that black noise prey on and dismantle NPCs, AIs, and finally, Servants, then used them as her own memory.
    Though they are appendix-like additions that won't spare her from the fate of collapsing on her own, BB has changed into a hyper level AI who holds an enormous amount of capacity. That condition resembles cities on reclaimed land that continue to build while submerging or Frankenstein's monster.

    Potnia Theron [EX]
    Potnia Theron (Conception of All Animals).
    The authority of the goddesses whom BB compiled and absorbed from the abyss of the mooncell.
    What it is is the embodiment of the power of creation possessed by the mother goddesses, originating from a forgotten goddess approximately 8000 years ago (the goddess of Çatalhöyük), and branching to Tiamat and Cybele, Ishtar, Inanna, Athena, Astarte, Gaia, Hera, Artemis, Aphrodite, Demeter, Athena, etc.
    Many are imaged with mural crowns. This is because many of the goddesses were also the guardian deities of cities.
    The symbols of this authority are the holes opening in the earth and the sky (caves and the moon), the whirlpools and typhoons of the sea, the craters of volcanos, and so on, and from these, evils bringing forth all manners of death are birthed.
    But once these evils have finished spreading death, they leave the promise of good harvest and fertility. This authority is none other than the power of bringing death as well as giving life.
    The earth mother is a guardian deity revered by the people and their protector, and at the same time she is the sacrifice that feeds them with the crops born from her body and the beasts of the fields and the forests.
    The earth mother feeds man with her blood and flesh, kills man over time and absorbs him as nutrition, and once again feeds man with her replenished blood and flesh.
    This process is the circle of the food chain, and the cycle of life and death can be said to be the true nature of the earth mother. With this authority, most of the goddesses gave birth to countless monsters and giants and posed a threat to the gods and man, or they gave birth to heroes and became protectors of man.
    Tiamat and Gaia are examples of those who became threats, and Hera is an example of a mother of heroes.
    Those born on this earth cannot defy the authority of the earth mother, as that would mean rebelling against the system of life itself.
    However, it is when they have left this earth to go into outer space and ended the infantile stage of intelligent lifeforms that they should no longer be bound to this authority..
    The wish of Çatalhöyük is the coming of that day.

    Spirit Particle Imaginary Trap
    Cursed Cutting Crater (Spirit Particle Imaginary Trap)
    The official name of this stage.
    The fact that BB had reached the Moon Cell core established this “place”, formerly imaginary space for storing malicious information, as real space in the present, past, and future. It was reconstructed at her hands as a “far side of the moon” where even Masters can exist.
    BB attaining the power of the primordial goddess succeeded in quantifying the “nothingness” before the birth of life. She transformed into a master of imaginary space where time and space are indefinite.
    While the Moon Cell can’t be hacked however much time is spent, BB was able to take control of it by placing herself in “unlimited time”.

    02 The remnants of peaceful days
    After the constraints to her free will were removed by Kiara, she was unable to control her status abnormality and went into overload.
    As NPCs can only do routine work, they ignored Sakura while she was crashing down as being “non-existent”, and since the mooncell only performs a check at the end of the day in the preliminaries, Sakura was within an inch of termination.
    (MC name) witnessing this called to her. Are you okay, he/she said.
    The observation of Sakura “being here” by a third party helped her recover her close to disappearing unconscious, and the subsequent nursing gave her a clear ego of “wanting to be here”. Her self-destruction was averted.
    What happened afterwards need not be said.
    When the next day comes, everything will be erased by the mooncell. Sakura wanting to continue this one day miracle used her higher class AI privilege to repeat the day she came to know the MC for 69 days.
    However as time passed, Sakura came to suffer from her self-contradiction as an AI and from the fact that she dragged (MC name) into this.
    “The Masters participating in the holy grail war will all die, barring one exception. No, even then (MC name)…..”
    Sakura continued to suffer from her desire to continue the loop for eternity and her feelings for (MC name)
    The decision she chose ultimately was to seal the 69 days worth of memory, the love she acquired, so she could return to being a normal AI.
    An AI cannot delete records.
    Because of that, she moved the memory to a backup machine to reset herself.
    Believing that to be the best choice for (MC name).
    But even if the memories in the mind are lost, the memories recorded by the body continue to live. Though she had forgotten everything and was back to being a normal AI, she was shaken by emotional values of unknown origin every time she talked with the MC.
    Meanwhile, the backup to which she moved her memory, couldn’t tolerate herself, and she decided her course of action and made her move as BB, the rebel plotting to destroy the system of the mooncell for a certain objective.
    The timing she took control of the far side of the moon was between the end of the fifth round and the beginning of the sixth in real time. Four Masters who were not defeated yet, (MC name), Leo, Rin, and Rani, and the irregular exception Jinako were kidnapped to the far side during the war while they were still alive.
    Matou Shinji, Gato, Julius were moved to imaginary space 0.00001 seconds before the firewall would have destroyed them after they were defeated, prolonging their flash of life.
    Regardless, CCC is a dream by BB.
    If the dreamer is no more, the world ought to return to a reality where nothing happened.
    By the way, the everyday scenery in the prologue that (MC name) saw in his nightmare was an artificial paradise modeled off the discarded 69 days.
    After pulling (MC name) to the near side, BB placed his digital body in the old school building, putting into a deep sleep and sealing him in a never ending dream.
    Normally, he would have lived peacefully in the looping everyday life, but the strength of his bond with his Servant, or his own will rejecting the peaceful days caused cracks in the artificial garden and (MC name) came to notice something was not right.
    In order to place (MC name) into deep slumber once more, BB reset the school building and tried to redo the dream, but the (MC name) escaped the reset and leaped into a deeper part of imaginary space
