Classification[edit | edit source]
Depending on the teachings of Magecraft schools, one could classify everything of reality into different sets of Elements. The four classical elements (Fire, Water, Earth and Wind) are said to came from Arche in ancient Greece. The Mage's Association adds in Void (Ether) and some other elements to make their classification more practical. Besides, there are the Five Elements in oriental philosophies (Water, Fire, Earth, Wood and Metal) and Twelve Constellations.
Elemental Affinity[edit | edit source]
A Magus is normally good at manipulating at least one of the Elements. To identify which of Five Great Elements his Elemental Affinity is, he can use Consecration (聖別, Seibetsu?), the method composed of the use of sage, tarot cards and personality tests. Some magi possesses more than one Elemental Affinity and sometimes use them at the same time. Those capable of manipulating all the five Elements receive the title of Average One: Wielder of Five Great Elements (五大元素使い, Godai Genso Tsukai?) and are highly valued by the Mage’s Association. For Magi whose Affinities are their Origins, completely different from the above Elements, Magecrafts using any of the Five Great Elements are difficult to perform, ones with their unique Affinities in turn are so easy to handle that they can occasionally realize what is impossible with normal Magecrafts. Elemental Affinity only indicates what kind of Magecrafts a Magus is good at, not meaning he can not at all use other Elements than his Affinity. To change one’s Elemental Affinity lead his ability as a Magus to decline dramatically.

Known Elements[edit | edit source]
Five Great Elements[edit | edit source]
- Fire (火, Hi?)
- One of the Five Great Elements (五大元素, Godai Genso?) that has Warm and Dry features. It is well suited for destructive Magecrafts, symbolizing life and death. In the Mage's Association, they call it normal. Paracelsus von Hohenheim assigned a red color to it following Tattva. Magi who have it and Water, the opposite Element, as their Affinities are few.
- Earth (地, Chi?)
- One of the Five Great Elements that has Cold and Dry features. Kiritsugu Emiya applies it to "bind" things that he "severed". Paracelsus assigned a yellow color to it following Tattva.
- Water (水, Mizu?)
- One of the Five Great Elements that has Cold and Wet features. Both this and Wind are good at liquid manipulation and Kayneth El-Melloi Archibald can make poisonous gas harmless using both of them. Paracelsus assigned a silver color to it following Tattva.
- Wind (風, Kaze?)
- One of the Five Great Elements that has Warm and Wet features. In the Mage's Association, they call it noble probably because a few number of its users. Paracelsus assigned a blue color to it following Tattva.
- Void (空, Kū?)
- It, also known as Ether (エーテル, Ēteru?), is one of the Five Great Elements. It also is called the Fifth Imaginary Factor (第五架空要素, Daigo Kakū Yōso?) according to the teachings of the Mage’s Association. It combines itself with any of the other four Elements in order to actualize the mysteries of Thaumaturgy. It is artificial magical energy that forms the basis of modern magecraft, although it did not exist during the Age of Gods. Although amorphous and incapable of materializing by its own power, it is what allows shapeless bodies to take a material form. Paracelsus assigned a black-purple color to it following Tattva.
- Ether Clump (エーテル塊, Ēteru Kai?)
- It, also described as Liquid Clay, is a failed materialization attempt of Ether through the combination with one of other Elements. Under normal circumstances Ether can only be materialized after combining itself with one of the other Elements. In some cases however, mainly when there is some sort of failure on the part of the Magus, it will take the physical shape of a clay-like substance. Somewhat related to the First Magic. Other than serving as a conductor of magical energy, it is completely useless. Whatever the shape it is given by a magus, if left inactive for long enough (i.e. without magical energy running through it) it will eventually return to its original clay-like form. Known uses include True Assassin’s Zabaniya, the first suitcase puppet of Touko Aozaki, Cornelius Alba’s slime creatures and the main component forming Leysritt’s body.
Imaginary Elements[edit | edit source]
- Hollow (虚, Kyo?)
- Also called Imaginary Numbers (虚数, Kyosū?), it is an Imaginary Element that gives its users access to Imaginary Number Space. Lev Lainur used it as a time capsule and Trisha Fellows put her head into it when killed to keep her killer from using her Mystic Eyes. When the Matou clan restraining spells are used along with this, it is possible to imprison and skewer the target into a separate dimension composed entirely of shadows. Furthermore, when Angra Mainyu's power is imbued on Sakura Matou, she is able to use this ability even against normal humans. It is a power highly effective against those made of Mysteries, such as spiritual beings, but not so potent against those who have physical bodies.
- Nothingness (無, Mu?)
- In magecraft, it is defined as that "which is not possible, but materializes", contrasting Hollow which is defined as that "which is possible but not in the physical plane". It has a different meaning than the "nothing" of physics and math.
Known Factors[edit | edit source]
Human's Factors[edit | edit source]
Factors of human beings are Body, Mind and Soul. Alchemists of Atlas can set all three Factors of theirs as an arithmetic unit to accelerate themselves.
Ether[edit | edit source]
True Ether[edit | edit source]
True Ether (真エーテル, Shin Ēteru?), otherwise known as the Fifth True Theoretical Factor (第五真説要素, Daigo Shin Setsu Yōso?), is magical energy from the Age of Gods. It is also described to form the nine heavenly bodies that gave birth to the planet. Although it does not exist in modern times, True Ether, which was of a far higher quality than ether, permeated the Earth in ancient times. Gods, as well as nature itself, were formed out of True Ether. The natural enemy of the Fifth Imaginary Factor (Ether), bullets of Black Barrel are composed of this substance.
Grain[edit | edit source]
Grain (ジン, Jin?, Gin), also called Space Dust (宇宙塵, Uchū Jin?), is the general term given to the toxic particles overflowing in the Earth of Over Count 1999, after the world lost its capacities to sustain life. Also called “ether” because even though poisonous, it promoted the surface of mutated life forms: the A-Rays, Liners and the Ether Liners.
The rate of energy transfer within the Grain-rich atmosphere is astonishing. A factor that resulted into the arise of a new method of combat that would not be possible in the old world. In a battle between A-Rays capable of absorbing Grain and Ether Liners wielding Knight Arms made of crystallized Grain, the power of conventional weapons is rendered useless.
Supposedly, Grain is the base component of all heavenly bodies. Therefore, the closer is the connection between a life form and its mother planet the greater will be the amount of Ether in their bodies. The greatest example of this would be the Ultimate One, the supreme existence of each respective’s planets and true avatars of their will.
Its antithesis is the True Ether or Black Barrel, which destroys Grain and anything containing Grain on contact.
Daemons[edit | edit source]
The Sixth Imaginary Factor (第六架空要素, Dairoku Kakū Yōso?), also known as Daemon, is a force that reacts to the desires of humans and births Daemons out of their wishes. It needs a form, invented by humans, similarly to how it happens to higher-level spirits, in order to materialize itself, as a passive existence. This passive existence is an individual daemon and not a true daemon.
But regardless of the result, as a rule, daemons are gentle. They are the Imaginary Factor that understands one's pain and attempts to remove it. Depending on perspective, one can say that they are allies of humanity. They use Reality Marbles as their Alien Common Sense.

Magic circuits are the pseudo nerves that a magus has inside himself. These are paths that generate magic energy and access the magic foundation engraved in the world. Magi make magic energy with the magic circuits and use the magic energy to run the magic foundation and thus put magery into effect. To do either of these, the magic circuits are necessary.
As suggested by the description pseudo nerves, these are split into cores and lines joining these together and are spread throughout the body.
The number of magic circuits are fixed at birth and the number won't increase by other than external factors.
The product of stamping the anchored mystery that a magus had spent his entire life building up. Can be said to be mystical inheritance that defines the magus line as a magus line. While the inheritor is young, it is necessary to implant this little at a time while at the same time having the body adjust to the magic crest by medicine and rituals. The magic association also has technology for extracting just the magic crest from the body and storing it.
What determines what kind of attributes a magus' magic is going to be likely to have, or what kind of magic the magus is going to have good chemistry with, is going to be the element aligned with the magus.
In addition to the five great elements of earth, water, fire, wind, and sky, there's the imaginary elements of Hollow and Nothing, for a number of seven.
Some of the five elements will differ according to the school of magic. A famous one is a style in which the five great elements are formed from wood, fire, soil, metal,and water.
Basically, one magus has one alignment, but sometimes there are magi with two alignments (like fire and earth, wind and water) and there are also those called "Average Ones" who have all the five great elements.
Matou Sakura normally would have been a holder of the imaginary element of Emptiness. However, through her magic training, hers had been changed to the water alignment of the Matou line, so she couldn't exhibit her true talent.
Five great elements Earth One of the two alignments of Kiritsugu. Kiritsugu exhibited his attribute of combining and used magic which combined the wounds of an enemy in a different form than normal, and made them unhealable.
Five great elements Water The alignment that the Matou magi have had for generations. Matou exhibit the attribute of absorption and have passed it on. Sakura's alignment changed from Emptiness to water.
Five great elements Fire The alignment of Tokiomi and also one of the two alignments of Kiritsugu. It is the symbol of life and death and has good chemistry with destructive magic.
Five great elements Wind One of the two alignments of Kayneth Elmelloi Archibold. There are few magi with wind as an alignment
Five great elements Sky An element which makes up celestial bodies that is newly added as a fifth element to the four great elements of earth, water, fire, and wind. This is, in other words, Ether.
Imaginary Elements Hollow The alignment that Sakura was born with. Defined, in magery, as that "which is possible but is not in the physical plane". Also called imaginary numbers.
Imaginary Elements Nothingness Like Hollow, the alignment of an imaginary element. In magery, defined as that "which is not possible, but materializes". Has a different meaning that the "nothing" of physics and math.
•The absoluteness called Origin
If alignment determines the root of one's magic, then even deeper than that, is the origin which determined the root of one's existence. The origin is not only for magi, but is the orientation that all things are born with and it's existence itself is thought absolutely necessary.
Those magi with an origin that is strongly expressed outwardly are sometimes removed from the normal alignments and there are times that the origin itself becomes the alignment. Most of those magi exhibit their talents as extreme specialists.
Because of that, it's said that they can reach higher grounds than normal magi.
Of the alignments, wind is called "noble" and fire is "normal". By the way, the term "Noble Colors" is used to refer to special and innate things where he workings of the magic circuit are close to the movements of a celestial body (normally they're closer to the movements of the crust), and is innate and special.
Noble Colors are often used to refer to mystic eyes, and Rider's petrifying mystic eyes are also a noble color.
 Tsukihime Dokuhon PlusPeriod - talk. Glossary: Forte [Name • Colloquial Term], p.200
Forte [Name • Colloquial Term]
A magus of the Association.
A rare magus who experienced gruesome melees such as protecting Seal-Designed Magi and recovering grimoire.
Forte favoured spells called Aero Strikes, and the sword acted as the magical staff.
There were three orifices on the body of the sword, thus the sword was not quite fit for slashing. The purpose of the orifices was to generate sound. Slashing the sword generated a resonant effect, producing an invisible impact on the target.
She looked like a blade-wielding swordsman, but this swordsman performed her swordplay hundreds of meters away from her opponent.
The oldest daughter of a mage lineage of many generations. It seemed like she encountered Aozaki, who also shared the Wind Element, several times.

One of the invitees to Adra, the Castle of Separation. An Astrologer. His elemental affinity is Wind. His aria, "Lead me," is also from Astrology.
Depending on the horoscope, he uses twelve knives marked for the twelve signs of the zodiac, and is able not only to predict the future but also to manipulate cause and effect within an extremely limited area. For example, things like creating a future where an opponent’s attack doesn’t hit.
He was actually one of the survivors of the Spiritual Tomb of Albion, as described in Grand Roll. Though his reputation as a master-killer and labyrinth returnee were decided rather early, the details about the Spiritual Tomb of Albion underneath the Clock Tower were decided rather late, causing quite some issues for the author.
 Lord El-Melloi II Case Files material - Encyclopedia: Adashino Hishiri [Person], p.096-097
Adashino Hishiri [Person]
The snake of the Faculty of Law. Her elemental affinity is Water. Her specialty is Poison.
In this story, she was El-Melloi II’s first rival. If Heartless is his Moriarty, then she is his Irene Adler. Though the chance of developing a romantic relationship with someone was never there for El-Melloi II.
In reality, much of her life was shaped by her desire for revenge against her father. Heading into the depths of the Spiritual Tomb of Albion on his own, he abandoned his ex-wife and son entirely out of nowhere upon his return. Giving birth to her through his second wife, he died a coward. In order to prove the worthlessness of her father, she joined the family of Norwich before slipping into the Faculty of Law, the easiest route for a magus with no pressure from their own bloodline.
As a result, she coincidentally received information from the Faculty of Law’s Information Division, and became strangely obsessed with a certain Doctor Heartless. She began pursuing him, thinking there was a possibility he was her long lost brother, Adashino Kurou.
If El-Melloi II had “a first rate sense of being a magus but a second rate skill,” then Adashino was “a magus of first rate skill, but no sense of being one.” Though her nature is closer to that of a Spellcaster, her place in the Faculty of Law which has given up pursuit of the Root fit her perfectly.
Though not explicitly stated within the work, her glasses are Mystic Eye Killers.
Just as her brother Heartless (Adashino Kurou) once possessed, she bears Mystic Eyes of Finding. In her investigations, the reason Hishiri was able to reach such precise results so quickly was because of those eyes. Of course within the Faculty of Law they were of great use, but they were also used to help find her brother.
As a bit of a digression, she has been entertaining herself greatly with the arrival of the new, plump, and somewhat out of place member of the Faculty of Law.
 Fate/Apocrypha material - Encyclopedia: Jean Rum [Person's name], p.169 [T]
Jean Rum [Person's name]
One of the people whose should have been a Master of the Red Camp. Female. Known as the Gale Wheel, she uses chakrams and possesses Wind-affinity magecraft just as her title implies. You really are exactly what you seem like, aren’t you? She’s a bibliomaniac, and according to rumor she searched for the library of Ivan the Thunder Emperor.
Her skill is definitely first-rate, but regretfully, she was easily subdued by Semiramis’ poison. The relatives of the Red Masters, excluding Shishigou and Shirou, make a stealthy appearance in “Fate/strange Fake” (Author: Ryohgo Narita, from Dengeki Bunko).
Well, things ended in massive failure for them in various ways, so even after being freed their positions have become precarious.
 Lord El-Melloi II Case Files material - Encyclopedia: Luviagelita Edelfelt [Person], p.111
Luviagelita Edelfelt [Person]
The most elegant (hyena) in the world.
Daughter of the illustrious Edelfelt family of Finland. For each incident it was planned for one guest from other Type Moon works to be included, and though it was decided (by the author) in the same way to include her, she was the celebrated first guest.
Her elemental affinity is Earth. Unlike the Red Devil that is fated to come some day, she is not an Average One with an affinity for all five elements, but her ability to unleash a wide variety of magecraft through the use of a plethora of gems gives her a level of skill that is not at all inferior.
Apparently having little interest in the Clock Tower’s own ranking system, though she turns up for the El-Melloi Classroom and the Faculty of Mineralogy, she has no particular enthusiasm for the Clock Tower’s other political games.
For a girl who travels from her home base in Finland, plundering secrets and Mystic Codes from magi around the world, the internal conflict of the Clock Tower seems like little more than a storm in a teacup.
“Though I recognize authority and history, they are by no means absolute.”
Rather, she would likely adore a gentleman she could respect from among the Lords and Nobility. As such, Luvia has a deep-seated desire to support someone she can respect. To write it in a way players of CCC would understand, in short, SG1.
Though her too-perfect ringlets are entirely proof of her status as a tsundere, the dere side of her character has yet to make an appearance in Case Files. A tsundere isn’t made up of just one person, after all.
The Edelfelt family are a rarity among magus families, taking the name of Scales in that they produce a pair of twins in each generation that both become magi. As such, of course, Luvia has a younger twin sister. As the complete polar opposite of Luvia, she is an introvert with an elemental affinity of Fire. Her marriage has already been arranged, and it is a thing of mutual love.
In addition, though it never came up in the story as it wasn’t particularly relevant, the Command Spell used at the end of Grand Roll was actually one that should have been entrusted to the overseer of the Holy Grail War. In short, it was one secretly carried back to their home country by Luvia’s ancestor, who participated in the Third Holy Grail War.
 Lord El-Melloi II Case Files material - Encyclopedia: Orlocke Caesermund [Person], p.099-100
Orlocke Caesermund [Person]
One of the invitees to Adra, the Castle of Separation. A user of Butterfly Magecraft. His elemental affinity is Wind.
Though he first appeared with the impression of a last boss, he ended up showing a rather good-natured side to El-Melloi II, and so ended up like that. His unexpected adaptability and understanding of Modern Magecraft likely stems from his distance from the political games of the Clock Tower, allowing him to judge based on merit alone.
As a magus capable of reaching the rank of Brand, he nevertheless found himself drowned in love.
Instigated by Geryon himself, Orlocke came to have a relationship with Geryon’s wife. Born from that affair, Granid Ashbourne was genetically Orlocke’s son.
The boy he ended up engraving his Magic Crest and personality on to at the end of the story was named Shanon. Perhaps that was the name Orlocke had intended to give to his own child someday…
Perhaps the sickness that struck down Orlocke was the same that claimed the lives of Geryon’s wife and son…
And perhaps all of that was part of Geryon’s plan from the beginning.
For now, it all remains a mystery.
But, his incantation of “Perform a dance” is something El-Melloi II will never forget.
ただ、「Perform a dance」と祈るような彼の呪文を、II世はずっと忘れることはなかった。
 Lord El-Melloi II Case Files material - Encyclopedia: Reines El-Melloi Archisorte [Person], p.110-111
Reines El-Melloi Archisorte [Person]
A true joy-seeker of a girl. Her elemental affinity is Water.
Adopted sister of the previous Lord El-Melloi, Kayneth El-Melloi Archibald.
To be accurate, if going by blood relations, she is Kayneth’s niece. Her mother, being particularly average in her talent as a magus, married into the Archisorte branch family instead of taking her own family’s name, where she had a number of children.
Following Kayneth’s death, the El-Melloi family fell into a state of great internal discord. As a result, just as described in the story, Reines became the successor after it was determined she happened to have the best affinity for the Source Crest. At that time, in order to put a rest to the strife between the Archisorte and Archibald families and demonstrate her right to succession, she accepted adoption into Kayneth’s family. Though, as a continued act of defiance, she still operates under the name Archisorte.
After the events of Case Files, she finally learns to control her Mystic Eyes specialized in precision analysis, and under the tutelage of El-Melloi II, continues to grow her own abilities well in the research field. In the same way she gave a personality to Trimmau, her practical ability to “layer her own magecraft over that of another” is a truly fitting achievement for the El-Melloi name.
Though it’s not demonstrated so clearly in the story, her political maneuvering is vicious. For example, remember how her first meeting with Waver was after she abducted him. The fact she is used to doing such things is a demonstration of her political style.
“There’s no way I would dislike Reines.”
That’s why, despite learning of the numerous conspiracies occurring in the Clock Tower, when Gray said those words to her, it must have been deeply relieving for her.
If one wonders where she learned to be so ruthless in her political dealings and the exercising of her authority, that was influenced greatly by the support she received from a certain butler. During the span of Case Files, however, he was not present, and thus did not appear in the story.

Ether lump [Others]
Ether, the Fifth Imaginary Substance as coined by the Association. It is a necessary medium that gives shape by mixing with the Four Elements.
It is shapeless, but it is a critical element in the functioning of magecraft.
Ether is bound to become one of Earth, Water, Fire and Wind, but in the hands of a novice, it would fail to become one of the Four Elements and materialize. This is ether lump.
Ether lump is completely useless. In some sense, creating ether lump is analogous to creating "Nothingness". Looking at it from this perspective makes it sound like "True Magic" In fact, ether lump is originally the First Magic's ----------

 Jonnobi: Demon
The 6th Imaginary Aspect. Existences born of the wishes of humans, passively (受動的な, shuudou-teki-na?, lit. "as acted upon") called forth by human desire. Manifest phantasms (実像幻想, jitsuzou gensou?) that take form via the aggregation of ideation (想念, sounen?, lit. "thoughts"). For materialization (実体化, kittaika?, lit. "manifestation to material") to occur, "a form fabricated by humans" is necessary. Not True Demons, but existences that obtain being by the imposition of a Designation (個体名, kotai-mei?, lit. "unit designation").
As Demons attain true freedom upon receiving a Designation, it is a general rule that the naming of Demons is not an act to lightly engage within.
Temporarily setting aside the outcomes of engaging with such, Demons may be assessed as allies of humanity, who exist so as to empathize with and resolve the sufferings of humanity.
 Fate/EXTRA material - Encyclopedia: True Demon [Circumstances], p.190
True Demon [Circumstances]
Even in the world of Extra, the concept of Demons (悪魔の概念, akuma no gainen?) is by humanity treated as the greatest of obstacles; so as God is to omniscience and omnipotence (全知全能, zenchi zenou?), so as demons as an existence are to mortal levels of awareness and impotence (人知無能, Jinchi Munou?, lit. "human intellect and impotence").
They are as an abyss (淵, fuchi?) that lies within arm's reach, yet decisively beyond comprehension.
Distinct from those demons from Stay Night, which exist only as imitations, the real thing -- Enfleshed Demons (受肉した悪魔, juniku-shita akuma?, lit. "Incarnated Demon") are that with which humans are incapable of competing 太刀打ちできない (tachi-uchi-dekinai, lit. "incapable of crossing swords"?).
(※ There is in record only a single instance in which an Enfleshed Demon was forced to disperse (退散, taisan?, lit. "disperse / retreat"), but that's a different story.)
In general, demons are existences that take possession, utilizing the corpus of a human to incarnate (受肉, juniku) and take action, but in the event that the psyche (精神, seishin?) of the human host (苗床になる人間, naedoko ni naru ningen?, lit. "the human that becomes a seed-bed") cannot withstand the strain, it is commonplace for self-annihilation (自壊, jikai?) of the host to occur, dispersing the essence of the demon into the vicinity.
There exist also humans who by way of their own acts (業, gō?, lit. "sins; worldly preoccupations / fixations / absorptions; karma") are subsumed unto the category of Demons as a result of losing their humanity; but these creatures that are said to have become Fiends (魔人, Majin?) cannot be considered True Demons.
In the world of Extra -- whether by way of Demonic possession, or in the circumstance that one's own actions bring about a transformation -- the phenomenon whereby a True Demon is birthed unto the world has, as of present day in 2030, not been brought successful fruition even once.
Though the classifications of "Demons" and "Fiends" do exist, their manner of existence is in essence indistinguishable from that of a higher-order lifeform (高次元生命体, kou-jigen seimeitai?, lit. "higher-dimension lifeform") that inhabits a different sphere of civilization (異なる文明圏, koto-naru bunmei-ken?) upon a different planet (異なる惑星, koto-naru wakusei?).
In sum, said existences can, per the recognition of the Universe of Awareness (認識宇宙, ninshiki-uchuu?, lit. "the universe derived of observation / perception"), no longer be discerned as "human."
Their existences would approximate to that of the cosmic horrors (邪神, jashin?, lit. "evil god") of a certain fictitious Mythos popular in the 20th century.
In the True Route of CCC, a certain individual that has undergone transmigration did indeed manage to reach this realm, but owing to a slight mistake, they were capsized from the Seat of Divinity (神の座, kami no za?).

Intrinsic Field. Originally referred to the alien common sense possessed by the beings called devils, but now also includes the unique boundary fields possessed by many people.
A subset of marble phantasm, it erodes reality and gives form to the user's imagined world. It is the sorcery closest to magic, and a forbidden art within the Association.
