1. #1Concept - Moon Cell

   Keys: moon cell, holy grail

   The Moon Cell, also called the Holy Grail, is a massive collection of photonic crystals within the moon. It was officially discovered and revealed to the wider world in 1973 by a Wizard employed by the United Nations, who had managed to infiltrate it via spiritron hacking and return alive from its first layer. The Moon Cell's depths contains a computer-like construct referred to as The Moon Cell Automaton.

2. #2Concept - Photonic Crystal

   Keys: photonic crystal

   Photonic crystals are a storage medium. Photonic crystals enclose light, regulating it through the use of nano-structures. The refractive index of the crystals periodically changes. Through manipulation of the photoconductivity of the crystals, light is used as a medium through which quantum computing is made possible. Research into their artificial creation is just in the starting phase for modern human society, with the largest size of crystal developed as of the start of the 21st century measuring less than several centimeters.

3. #3Concept - Moon Cell Automaton

   Keys: automaton

   The Moon Cell Automaton is a large computer-like construct created by an unknown non-human civilization one hundred million years before the existence of the Earth or the Moon. It acts as the core of the Moon Cell and has recorded everything that has happened on the Earth since its formation, scanning the entire planet about once per nanosecond and compiling the results of its scan into its database. It acts as a record of human history that can also provide definite predictions of the future through its accurate simulations of all life on Earth. It is a processor with a massive memory that has recorded the habits, history, ideas, and even the souls of humanity. The computer is a pseudo-intelligent being that has the ability to affect the outside world with its internal calculations. The Automaton's god-like power could effectively "grant wishes" for anyone who somehow managed to gain administrator permissions. In terms of processing power, the Moon Cell absolutely dwarfs all of the greatest supercomputers on Earth combined.

4. #4Concept - Serial Phantasm

   Keys: serial phantasm, se.ra.ph, seraph, photonic abyss, angelica cage

   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 the Moon Cell Automaton. SE.RA.PH manages each Holy Grail War, summoning Servants, restricting participants from leaving, and generating locations and NPCs. SE.RA.PH monitors the ongoing tournament at all times to ensure that everything is proceeding according to the rules set by the Moon Cell Automaton.

5. #5Concept - Holy Grail War

   Keys: holy grail war

   The Holy Grail War is a method of data collection utilized by The Moon Cell. The entire process is managed by SE.RA.PH. All participants must enter the Moon Cell via the digitization of their souls, meaning that all connection methods except for Spiritron Hacking are rejected. In the case of disqualification or loss, participants are killed as a result of the data comprising their souls being deleted. Dying in the Holy Grail War manifests externally as a participant dying at their terminal from cardiac arrest—resulting from their body's neurons being overloaded. A Holy Grail War starts with 999 participants who are pared down to 128 Masters through preliminaries. The 128 Masters are each given a Servant and do battle in a tournament format until a single victor remains. No participants are allowed to disconnect prior to the tournament's conclusion. The winner of a Holy Grail War is supposedly granted administrator permissions for the entire Moon Cell.

6. #6Concept - Preliminary Testing Round

   Keys: preliminary, preliminaries, prelim

   The Preliminary Testing Round is the first stage of the Holy Grail War, lasting one week. All 999 participants that manage to successfully connect to the Moon Cell have their memories suppressed and are implanted with false memories, with each participant being led to believe that they're either a student or faculty member of Tsukumihara Academy depending on their age. When a participant realizes that they're trapped in a false reality—which will most likely occur due witnessing subtle glitches or inconsistencies—they're given a final test. The first 128 participants to pass the test have their memories restored and are allowed to move onto the actual tournament. Anyone still alive who failed to secure a spot in time is deleted.

7. #7Concept - Elimination Battle

   Keys: elimination, elim, duel

   Elimination Battles are held at the end of every week of the Holy Grail War. Each remaining Master-Servant pair must report to the elevator at their scheduled time for their duel against the other Master-Servant pair that they were matched up with at the start of the week. Battles take place between two Master-Servant pairs in the week's Colliseum. A battle ends as soon as a member of a pair is too grievously wounded to continue fighting. The winners of the battle are allowed to move on to the next week of the tournament, and the losers are both deleted.

8. #8Concept - Final Test

   Keys: final test

   During the Preliminary Testing Round of the Holy Grail War, Masters who manage to figure out that they're trapped in a false reality are given a final test to determine if they're going to be allowed into the tournament. A potential Master is given an Effigy and is expected to command it like a Servant in a battle against another autonomous Effigy. Winning the battle results in moving on. Losing the battle results in death.

9. #9Concept - True Name

   Keys: true name

   The True Name of a Servant is their actual name. During a Holy Grail War, each Master is typically aware of their Servant's True Name but will still only refer to them by their class name. If an enemy Master were to learn your Servant's true name, they'd be able to make educated guesses about their traits and abilities—making it easy to develop countermeasures or abuse weaknesses that they had in life. Tamamo apparently intended to hold off on revealing her True Name until later on, but accidentally referred to herself in the third-person when first introducing herself to .

10. #10Concept - Wizard

    Keys: wizard, spiritron, spirit, magus, magi

    Wizards, also called Spiritron Hackers or Spirit Hackers, are a relatively new class of magus that emerged in the late 20th century as a result of the Earth's mana beginning to dry up in the early 1970s. Unlike a regular Hacker who utilizes traditional digitization methods to interact with the digital world, a Wizard is an individual capable of Spiritron Hacking. Technical knowledge about computer systems and hacking skills are not particularly important for wizards, with physical ability and mental prowess being far more useful. Every Wizard is a Hacker, but not every Hacker is a Wizard.

11. #11Concept - Codecast

    Keys: codecast, code cast

    Codecast are spells utilized in cyberspace. A Wizard writes and compiles the program code for a Codecast in advance, and activates it by passing magical energy through it while Spiritron Hacking. Codecasts are unable to be used in the real world for obvious reasons.

12. #12Concept - Magic Circuit

    Keys: magic circuit

    Magic Circuits are a pseudo-nervous system that spreads itself through the human body and what qualifies a person to be a magus. Magic Circuits originally had two basic functions: one is to convert Life Force into magical energy, and the other is to allow their owner to activate Magic Formulae. With mana having dried up these days, Magic Circuits are now primarily used for Spiritron Hacking and activating Codecasts. Magic Circuits are inherited through genes and not something that can be obtained through training. The more Magic Circuits one has, the less limits they encounter when interacting with the digital world.

13. #13Concept - Magical Energy

    Keys: magical energy

    Magical energy is a source of energy found naturally within magi and the world. When coming from the world, it's referred to as "Mana" or the "Greater Source". When coming from within living organisms such as humans, it's referred to as "Od" or the "Lesser Source".

14. #14Concept - Od

    Keys: od, lesser source

    Od is a source of magical energy found within living organisms such as humans and animals. It's the life force energy of the being that it's contained within. Once depleted, the Magic Circuits that are stored in the soul will begin to replenish it. Od is produced as long as one lives, but the amount a person can store varies from individual to individual.

15. #15Concept - Mana

    Keys: mana, greater source

    Mana is a source of magical energy found in the atmosphere of the world. Mana is produced by the world through a network of Leylines across the globe. A major unknown incident occurred in the 1970s that caused the world's mana to start drying up. The worldwide depletion of mana brought about the end of traditional magecraft due to a loss of easy access to magical energy, leading many magi to become Wizards and redirect their studies towards Spiritron Hacking.

16. #16Concept - Visual Perception Digitization

    Keys: visual perception, digitization, spinal insert

    Visual Perception Digitization is a method of interfacing with the digital world utilized by Hackers. It allows a Hacker to visually view information streamed directly into their brain through the use of a spinal insert. The connection is one-way, only allowing a user to receive and read information.

17. #17Concept - Visual and Touch Perception Digitization

    Keys: visual and touch perception, digitization, nerve connection

    Visual and Touch Perception Digitization is a method of interfacing with the digital world utilized by Hackers. It allows a Hacker to project the basic components of their being onto the net through a somewhat complex physical connection directly to their body's nerves. It allows for both input and output since a user can both see and interact with data, but requires more invasive equipment than the input-only Visual Perception Digitization.

18. #18Concept - Spritron Hacking

    Keys: spiritron hacking, digitization

    Spiritron Hacking is the process of an individual materializing their consciousness into a digital image, allowing them to interface with the cyber world by sending their soul into it. The procedure of conceptualizing one’s digital image differs from person to person. Although it allows for a much greater degree of control over one's digital form compared to more traditional hacking methods, it also puts the user at much more risk due to their soul being directly exposed to potential threats. Utilizing spiritron hacking requires one to have functional Magic Circuits, and being able to do so classifies them as a Wizard.

19. #19Concept - NPC

    Keys: npc, non-player character

    NPCs (Non-player characters) are humanoid virtual lifeforms created by SE.RA.PH to manage the Holy Grail War. They're artificial intelligence configured with specific tasks in mind. Each NPC is created from the Moon Cell's records of real humans that lived in the past, and they simulate the personalities of them as a result. Despite acting very human, NPCs are nothing more than puppets used by SE.RA.PH to interact with participants in the tournament.

20. #20Concept - Enemy Program

    Keys: enemy program, attack program

    Enemy Programs, or Attack Programs, are hostile programs within the Moon Cell. Although their intended purpose is to provide Holy Grail War participants something to train against in the Arena between Elimination Battles, Enemy Programs do not hold back in battle and can kill Masters and Servants if they're ill-prepared to face them. The programs always have single-colored bodies covered in patterns of glowing lines. They range in appearance from abstract floating polygons to vaguely animal-like.

21. #21Concept - Effigy

    Keys: effigy, effigies

    An Effigy is a program used during the Preliminary Testing Round of the Holy Grail War. They resemble gold humanoid statues covered in glowing orange lines. Their arms and legs end in points, and appear to float slightly away from their torsos rather than being directly attached. Effigies have no faces, are incapable of speech, and follow any commands given by the Master that they're temporarily assigned to for the duration of the test.

22. #22Concept - Fate/the Fact

    Keys: fate/the fact, internet magazine, wizard magazine, hacker magazine, hacking magazine, tech magazine, conspiracy, urban legend

    Fate/the Fact is a monthly magazine distributed by the publisher Netwalker. Describing itself as an "Internet Deep Culture Magazine", it covers a variety of topics related to the internet, technology, and hacking. Conspiracy theories and urban legends related to the previously noted subjects are also featured on a regular basis. The magazine received several hundred lawsuits from the Western European Conglomerate for publicly leaking information about the Moon Cell's existence and the Holy Grail War to the public.

23. #23Concept - International Agreement 404

    Keys: international agreement, 404, moon

    International Agreement 404 refers to an agreement that forbids all forms of contact, investigation, analysis, and declarations regarding the moon. It was put forward by the Western European Conglomerate and agreed upon by all of the countries in the North Earth Resource Organization. Individual citizens of NERO countries rarely ever get in trouble for discussing the moon as the agreement was mainly introduced as a way to prevent large groups like governments and news agencies from drawing mass attention to the moon.

24. #24Concept - Satellite

    Keys: satellite

    The launching of new satellites was forbidden in 2015 and all satellites currently in orbit can only act through the Western European Conglomerate's INQ-EXIT assessment system. It's currently effectively impossible to survey the lunar surface using satellites as existing satellites can't send information about the moon and new satellites designed to bypass restrictions can't be sent into space.

25. #25Concept - Terminal

    Keys: terminal

    Terminal is an umbrella term used to refer to any device capable of connecting to the internet, primarily used in hacking circles when the exact method that someone used to connect is uncertain. It could be a computer, a smartphone, or anything in-between.

26. #26Concept - INQ-EXIT

    Keys: inq-exit, assessment system, internet

    INQ-EXIT is an assessment system created by the Western European Conglomerate that enforces all databanks to allow its operation. It's impossible to connect to the internet without going through INQ-EXIT. The system is meant to prevent the spread of information regarding the moon.

27. #27Concept - Piece Journal

    Keys: piece journal, pj, blog

    Piece Journal, abbreviated as PJ, is a popular blogging website based out of Europe. Unlike normal blogging sites used for posting and sharing regular news, it's more of place for self-declared "experts" on niche topics to flex their extensive knowledge. Users typically care a lot about their follower counts.

28. #28Concept - Heaven's Feel Online

    Keys: heaven's feel, mmo, massively multiplayer online game

    Heaven's Feel Online is a popular massively multiplayer online game with over twenty million players worldwide.

29. #29Concept - UVD-ROM

    Keys: uvd, cd, dvd, blu-ray, disc

    UVD-ROM is a digital optical disc data storage format designed to supersede the Blu-ray format. It's capable of holding up to 16 terabytes of data.

30. #30Concept - T Regulations

    Keys: t regulations, esrb, cero, pegi, content rating

    "T Regulations" jokingly refer to the CERO B, ESRB T, and PEGI 12 content ratings that Fate/Extra received prior to launch. Tamamo would normally break the 4th wall and blame the ratings boards for preventing her from doing anything particularly naughty with . Upon further consideration, those old requirements are inapplicable here...

31. #31Group - Western European Conglomerate

    Keys: western european conglomerate, western european plutocracy, europe

    The Western European Conglomerate is an economic organization with numerous subsidiaries that control many nations. The Harwey family acts as the head of the conglomerate. About 30% of the world's land and 60% of the world's wealth, based on GDP, belong to it. They indirectly govern all of the countries in the North Earth Resource Organization. The group even has its own private army, referred to as its Counter-Terrorism Unit. Rather than force, the Western European Conglomerate primarily relies on information control to keep the populace in line. In summary, the organization effectively rules the world.

32. #32Group - North Earth Resource Organization

    Keys: NERO, North Earth Resource Organization

    The North Earth Resource Organization (NERO) is an organization of 45 countries that was created due to the urging of the Western European Conglomerate in 2015. Its main goals are to strictly limit the excavation and utilization of earthly and lunar resources. Since most of the countries in the northern hemisphere are members of it, all resource excavation activities on Earth are in fact controlled by NERO. All of the countries that joined the organization put a stop to their space programs and ceased any further research in the field.

33. #33Group - Anti-NERO Alliance

    Keys: anti-nero

    The Anti-NERO alliance is a group comprised of 68 countries that oppose the North Earth Resource Organization.

34. #34Group - Atlas Institute

    Keys: atlas, institute

    The Atlas Institute is an organization of alchemists who consider themselves the last of the remaining old world magi. They're known to frequently conduct experiments involving homunculi, which is prohibited by the law in the majority of countries around the world. Their headquarters is located in Northern Africa.

35. #35Group - Hack&Crack

    Keys: hack&crack, hackandcrack, hack & crack, hack and crack

    Hack&Crack was an intel-gathering organization that investigated novel hacking skills. It was based out of Bangladesh and was mainly active in the Middle East. The group discovered that surveillance of the moon's surface was secretly underway at Akalabeth and publicly released the information that they were able to gather regarding the matter. Shortly after the release of the report, Hack&Crack's headquarters were destroyed in a large-scale aerial bombing conducted by Indo-American ally forces.

36. #36Group - Netwalker

    Keys: netwalker

    Netwalker (stylized as "Netwalker.") is a publisher best known for distributing a magazine called Fate/the Fact. Wishing to avoid censorship and retaliation from the Western European Conglomerate, they do not publish contact information with their publications.

37. #37Group - Harwey Family

    Keys: harwey

    The Harwey are a magus family. They act as the head of the Western European Conglomerate.

38. #38Group - Tohsaka Family

    Keys: tohsaka

    The Tohsaka family is a Magus lineage. The household fell into obscurity in the late 1990s. Its most notable member today is Rin Tohsaka.

39. #39Location - Akalabeth

    Keys: akalabeth, lunar exploration, lunar survey

    Akalabeth is a facility in the Middle East dedicated to lunar exploration. It was officially stated to be abandoned in the 2010s, but surveillance of the lunar surface from the location covertly continued in connection with the Western European Conglomerate. The group working out of Akalabeth suffered a data breach at the hands of Hack&Crack and both their actions and link to the Western European Conglomerate were revealed to the world.

40. #40Location - Arena

    Keys: arena, training

    The Arena is a virtual space where Masters competing in the Holy Grail War can venture out into the week's designated Chimeric Lunar Sea for training and information gathering purposes prior to that week's Elimination Match. Various Enemy Programs are generated in the Arena by SE.RA.PH can be used for practicing battle strategies. Matched up Master-Servant pairs can technically attack each other in the Arena prior to their scheduled Elimination Match, but SE.RA.PH will forcibly separate them from one another after a brief period of engagement.

41. #41Location - Colliseum

    Keys: colliseum, elevator

    Every one of the Chimeric Lunar Seas has a Colliseum at its deepest point, reachable via a long and tense elevator ride down. Colliseums appear to be open spaces similar to the rest of the Lunar Sea, but prevent participants in Elimination Battles from exiting their invisible boundaries until the battle's conclusion. The aesthetics of each colliseum reflects those of the Lunar Sea that it's located within.

42. #42Location - Chimeric Lunar Seas

    Keys: lunar sea

    The digital landscapes within the Moon Cell generated by SE.RA.PH are referred to as the Chimeric Lunar Seas. Although varying greatly from one another in terms of theme and color palette, one constant between all of them is that the locations depicted are underwater. Individuals within the spaces are able to act normally as the physical sensations associated with being completely surrounded by water are absent. Underseas ruins and bits of terrain appear to float weightlessly in place, ocean life and rising air bubbles are regularly move about, and the water's surface with the sun shining beyond it is sometimes visible in the sky depending on the apparent depth of a given sea.

43. #43Location - Tsukumihara Academy

    Keys: tsukumihara, academy, school

    Tsukumihara Academy is an environment within the Moon Cell that resembles a stereotypical Japanese high school with early 2000s architecture. It acts as a false reality in the Preliminary Testing Round, and housing for Masters in the actual tournament.

44. #44Location - Private Room

    Keys: private room

    Each of the 128 Masters participating in the Holy Grail War is given a classroom at Tsukumihara Academy to utilize as a private room. The rooms are completely isolated and it's impossible for anything discussed within the room to be overheard or divulged to others. They default to looking like regular classrooms but can be heavily customized by an experienced wizard.

45. #45Outfit - Blue Witchcraft-User's Clothes

    Keys: witchcraft-user's clothes, kimono, loungewear

    Tamamo's usual outfit is her blue and black kimono. She feels most relaxed when wearing those clothes compared to any alternative options. They're her favorites, but she does like to change things up and would also gladly try on other clothes if wants her to.

46. #46Outfit - Spring Coloured Modern Clothing

    Keys: modern clothing, casual wear, hoodie

    Tamamo's casual outfit consists of a pink and white striped hoodie worn over a pink bra, black short shorts with pink frills, black thigh-high socks with pink frills that match the shorts, and a pair of black shoes. She typically styles her hair into twintails with black scrunchies to complete the look. Caster likes how she and look more like a real couple when she wears more normal-looking clothing.

47. #47Outfit - Tsukumihara Academy Uniform

    Keys: student, school uniform

    The uniform for Tsukumihara Academy, which is applied to all participants given the role of students in the Preliminary Testing Round, is a relatively normal-looking Japanese school uniform. The boys' uniform consists of a brown jacket paired with brown pants, and the girls' uniform consists of a brown jacket with a blue bow paired with a skirt. A patch with the school's emblem, a crescent moon, is located in front of the jacket's breast pocket.
