Magus

is the term for a practitioner of magecraft, the magical science, as opposed to a Magician, who is capable of bringing forth true miracles that are impossible to be reenacted at the current scientific stage. 
In ancient times, the term magus was used for both the users of magecraft and Magic, but with the advancement of science that made past miracles possible and the decline of the overall power of magecraft, the differences between the two became clearer. In the modern age, there are only five Magicians left. A Magician, just like a magus, has a long life. If one uses life-prolonging magecraft, it wouldn't be impossible to live a few hundred or thousand years, either.
Magi frequently, but not necessarily, descend from old magical families, as affinity to magecraft is something transmitted through blood relations.
More than just a name, the term "magus" defines a whole set of beliefs and lifestyle, the first of which is the desire to reach the "Truth". No matter the cost, they use all their assets and abilities to reach that goal, and any abilities gained in the process are a by-product. They hold no meaning except as a means to reach the Truth. 
A magus also dedicates himself to the study and refinement of magecraft while driving himself apart of the values of common people in the process. He searches for the greater truths of the universe not to answer existential questions, but just for the sake of knowing. 
Ideally, a magus would render his own self transparent while still retaining his ego. In reality, however, most magi, especially those of the Mage's Association, are often caught up in petty power struggles. On the other hand, those who openly deviate from the way of magi, such as Kiritsugu Emiya and Shirou Emiya, are perceived as heretics that do not deserve to be called a magus. They have no interest in the Truth and see magecraft as a useful tool. They are called Spellcasters.
==Characteristics==
Depending on their craft, the appearance of magi may become distorted due to the chemicals with which they work or type of magecraft they practice. Rather than become ashamed over it as a mark of humiliation, it is normal for them to see it as a source of pride.Fate/Apocrypha Volume 1: Apocrypha: Great Holy Grail War - Chapter 1
Many magi look down on those like freelancers who use magecraft to earn a profit, believing it to be solely a field of research that should not be used in such a manner. Only those with more worldly experience or those practicing more controversial magecraft can look past the initial disdain and bewilderment other magi have for such people.
It is possible for magi to obtain magical patents recognized by the Clock Tower, allowing them to obtain money from theories and rituals in the same manner as regular patents. The Tohsaka family earns tens of millions of yen annually from those that they own.
===Mindset===
Most magi of long lineages do not find convenience in using modern technology, believing that the comparable magical tools they have possessed since long before the technology was invented will never be inferior. Compared to communication tools that are susceptible to spying and that will stop working with power outages, they feel their own apparatuses like Tokiomi Tohsaka's implements in place of fax machines and phones will remain superior due to not having such issues.Fate/Zero Volume 1: The Untold Story of the Fourth Holy Grail War - Act 1 Part 3 -282:14:41 Others make the argument further that, while Science and magecraft sleep in the same bed, if the methods are too directly scientific, it gets farther away from the Mystery.Lord El-Melloi II Case Files Volume 1: case. Adra Castle Separation - Chapter 3 Part 3 
Magi are usually unused to such technology, with Irisviel von Einzbern being hard-pressed to understand how to properly use a phone,Fate/Zero Volume 3: The Scattered Ones - Act 9 Part 4 -91:23:15 Jubstacheit von Einzbern fervently arguing against Kiritsugu Emiya having a telephone line and power generator installed at the Einzbern Castle,Fate/Zero Volume 1: The Untold Story of the Fourth Holy Grail War - Act 1 Part 2 -282:14:28 and Rocco Belfeban believing social networks to be a form of magecraft and misunderstanding writing an email as being like sending a physical letter.Fate/strange Fake Volume 2 - Chapter 6: Day 1, Noon "Two Archers and..." 
People like Kirei Kotomine cannot truly understand this train of thought, believing that a fax machine that can be used by anyone is more convenient, and Kiritsugu, a magus who frequently uses such technology, finds that the tendency of magi to ignore such technology as a legitimate threat, not understanding what a regular human can accomplish without magecraft, is a blind spot he can exploit in his work as a Magus Killer.Fate/Zero Volume 1: The Untold Story of the Fourth Holy Grail War - Act 3 Part 1 -162:26:39 
Nevertheless, it's not necessarily the case for every magus: those of families that do not follow such traditions like Waver Velvet are easily capable of using them to the degree of any ordinary person,Fate/Zero Volume 3: The Scattered Ones - Act 10 Part 4 -84:23:46 and even a Clock Tower Lord like Inorai Valualeta Atroholm enjoys modern technology for her own pleasure, such as owning an ,Lord El-Melloi II Case Files Volume 2: case. Twin Towers of Iselma (Upper) - Chapter 2 Part 4 a personal computer, and a cineplex.Lord El-Melloi II's Case Files Volume 9: case. Grand Roll (Middle) - Prologue In the same vein, the Archelot family head is into modern trends, and the family has been a part of television media for years, with one of their members even having been a world renowned idol singer. New Age magi, to compete against the old magi families who can rely on the Magic Circuits and Magic Crests built up by their ancestors, turn to modern science and the media to try and gain an advantage by doing something new.
The Mage's Association does not base its principles on normal morality, but rather the preservation of the secrets of magecraft, the , one of the Mage's Association's three great principles,Mahoutsukai no Yoru - Chapter 6: "Like a Dog" and the first of its ten commandments.Mahoutsukai no Yoru - Chapter 4: "Her Name Is Blue" What magi consider a crime is the popularization and the vulgarization of Mysteries, so while magi may commit horrendous crimes like murder, they generally will not be targeted so long as it does not become a threat to their secrecy. While many people may perish in the Holy Grail War rituals, the Association only seeks to make sure the media is properly manipulated as to avoid letting it become public and having the Einzbern cover any monetary damage. 
However, perhaps out of pragmatism, the Association forbids the criminal use of magecraft. It does not allow research that would harm societyFate/stay night - Fate route - Day 1: One day - Morning in the Emiya household or involve innocents.Fate/stay night - Unlimited Blade Works route - Day 5: Bonnie And Clyde - Everyday (II) If a magus pulls a civilian into a magical phenomenon, the Association dispatch assassins to kill that magus.Kara no Kyoukai Volume 5: Paradox Spiral (Enjoh Tomoe) - /6 
One rule among magi is that it is taboo to kill your own students, because it goes against a magus' instinct of passing on their hopes to reach the Root on the next generation.Lord El-Melloi II's Case Files Volume 8: case. Grand Roll (Upper) - Chapter 5 Part 3 Since students and apprentices are like their own offspring and they are like their parents, magi fight fiercely to protect them, no matter what.Kara no Kyoukai Volume 5: Paradox Spiral (Enjoh Tomoe) - /11
When hunting those who have been given a Sealing Designation, their greatest priority is ensuring the safety of the results of the designated's research over all else. Competing with the Holy Church in their goal of wiping out all heretical knowledge, they seek most of all to obtain the Magic Crests of the designated as the most precious of a magus' work. In the case of Norikata Emiya and his successor Kiritsugu Emiya, the Association keeps the majority of the Magic Crest, and only through negotiations of the one selling it to them, Natalia Kaminski, is Kiritsugu able to inherit a minor portion.
===Families===
Some magus families will develop branch families over time. Among the Clock Tower families, the main family name sometimes will be bestowed upon a branch family member as a middle name to indicate being directly under their care.Lord El-Melloi II Case Files Volume 2: case. Twin Towers of Iselma (Upper) - Chapter 2 Part 2 
The magi of Yggdmillennia take on "Yggdmillennia" as their last name, while their former family name is taken as their middle name.Fate/Apocrypha Volume 1: Apocrypha: Great Holy Grail War - Chapter 1 The Barthomeloi family puts their family name before their given name, similar to .Character material - Barthomeloi Lorelei, p.16 Within Atlas, the family name of a magus is used as their middle name, while the last name is a chosen name or title.

* - The practitioners of Curse Arts, through similar in concept they are seen as a different kind from the regular magus. Users include the Fujou clan in the world of Kara no Kyoukai, Alice Kuonji, and, at first, Ayaka Sajyou.
* - The name given to those who use magecraft without following the way of the magus, such as Kiritsugu Emiya and Flueger who treated magecraft as just a tool. Usually, their general skill with magecraft is low, but it is not uncommon for them to be highly proficient in a single field that they choose to specialize at. Also includes magi who lack formal training such as Shirou Emiya and Sakura Matou.
* - A magus that uses Spiritual Invocation to perform medical operations, one who heals not through the flesh, but through the soul.

They resonate with the natural wavelength of the Crest, better matching it with the wavelength of the host. Due to the Crest being akin to a living being, its natural wavelength differs from the magus, so syncing the two increases the effectiveness.

===Aozaki===
The is the family who administers the greatest Spiritual Land in Japan. For magi of the Clock Tower, this name is a synonym for "trouble". Despite its age, it is not a renowned lineage. A bloodline with a history worth a total of six generations, the head of the third generation was a genius that discovered a path to the Root under his land. After creating the Fifth Magic, however, he sealed this path and decided to wait for someone who had the potential to comprehend the Root. He was the Fifth Magician until he passed on the Fifth Magic to his successor, and was a "magus infinitely close to being a Magician" afterwards until his death. By using this path, the successive heads have a high chance of inheriting the Fifth Magic, but going further into touching the Root is forbidden. 
The family head during most stories is Aoko Aozaki.
In the present generation, the family had the misfortune of having siblings disputing over the position of family head, a tragedy for any clan of magi. The outcome of the conflict was that the younger of the two sisters, Aoko, emerged victorious and became a Magician. At a point of time, both sisters were part of the Mage's Association but eventually they withdrew from it. Aoko left on a whim and became a Freelancer. Meanwhile, the older sister, Touko Aozaki, ran away after receiving a Sealing Designation after realizing that if she remained with the Association she would never be able to leave later, despite the great chance of her reaching the highest levels of the place.
The Aozaki family never had a history of producing heirs with many Magic Circuits and the numbers were decreasing even more with the passing of generations. By the time of the fifth generation, there were almost no Magic Circuits left. Many though that was the end for the Aozaki lineage, but Touko of the sixth generation surprisingly turned out to be a prodigy with 20 Magic Circuits.
About the time of the Fifth Holy Grail War, Touko was still hiding herself from the Association, while Aoko was touring around the country without a care in the world.
While Touko is a very versatile magus, Aoko is good at nothing but destruction, being a user of the Fifth Magic, "Magic Blue".

Among their members was Assassin's Master in the Third Fuyuki Holy Grail War, who recorded mystic memories through the puppets he used in the War, and transmitted them to his family, even to distant relations. Eventually, Faldeus’ grandfather joined hands with United States politicians and military leaders, and developed a plan to hold a Holy Grail War on their own land within several centuries. When Faldeus' father inherited the project, Francesca proposed cultivating a stolen portion of the Fuyuki Holy Grail, which allowed their Holy Grail War to occur in less than a century.Fate/strange Fake Volume 2 - Chapter 5: Day 1, Dawn "The Shadow in the Dark" Two known members have participated in a Holy Grail War.

===Escardos===
The is a particularly old lineage even within the Mediterranean Basin. It was rumored to have been active centuries following the dawn of the Common Era, alongside the Magician Kischur Zelretch Schweinorg. No one at the Clock Tower believed it, nor did the descendants themselves—after all, although their family was old, they hadn't produced any worthwhile results. Even their Magic Crest had only age to recommend it. The greater portion of spells was indecipherable, even to the heirs themselves. The Magic Crest did, however, contain advanced life preservation capabilities so they managed to just barely cling to their dignity as an old family.Fate/strange Fake Volume 4 - Chapter 12: Day 2, Daytime "Genius Was Not Built in a Day; All Magecraft Leads to Disaster"
Mocked by the Clock Tower as "moldering antiques" their only wish was for their Magic Circuits to develop. While their Magic Circuits remained few down the generations, their Magic Crest had yet to show signs of reaching the end of its lifespan. The Escardos family found this preferable to dwindling like the Makiri and they worked hard to shore up their footing as magi to avoid that fate—even if other magi laughed at their wasted effort.
After a few centuries of that, an "anomaly," Flat Escardos, was born into the Escardos family. He had Magic Circuits unparalleled within his lineage, genius Magical Energy control, and the originality to combine spells from the past into a unique new magecraft. He was believed to have been the ideal heir, but as his talents began to bud, it became clear that he had entirely lacked the "mental attitude" that could be called a magus' most important attribute. Though known only to Zelretch and Van-Fem, Flat is the result of the 1,800 year old dream of the Escardos family.Fate/strange Fake Volume 4 - Intro Chapter: "-"

===Fraga===
The , a family with a history that extends back to the Age of Gods. Due to the faithful servitude they showed to the ancient deities in the past, the clan was rewarded with the knowledge of mystic runes and rights over the Noble Phantasm Fragarach. From the Magi's standards they are supposed to be the top-elite, but for some reason decided to remain isolated in a small coastline village. By bloodline alone, they should have been seen as high class, but in truth possess neither money nor fame. Instead, they just live secretly while passing down their mystical knowledge to their descendants, one child in the family per generation.Fate/hollow ataraxia - Heaven's Feel - 3/ Dialogue Mobiuslink
They possess the Sorcery Trait God's Holder: the remains of a Mystery of the Age of Gods in the form of a virus. Not an hereditary trait carried in the genes, but rather a pathogen that has been transmitted throughout the generations. Allows the recreation and use of the Noble Phantasm Fragarach.

It is traditional for the children of the house to be left nursed by Golems from the moment of birth, and until they reach the age when the family Magic Crest can be transferred to them, their parents practically never leave the workshop to see them. It was the policy of the Frain family to be raised and not give any love from the beginning. The Golems have complete responsibility even for their education. As such, every child of the clan becomes very familiar with Golems. The acts and speech of these dolls modelled after human beings—the way they continue to work day and night—becomes what is common sense to them. Having been raised on such an eccentric upbringing, they become magi for whom Golems rather than other humans are the norm. They may have forgotten even the faces of their own parents, but they remember the form of every single Golem who has cared for them.Fate/Apocrypha Volume 1: Apocrypha: Great Holy Grail War - Chapter 2

===Fujimiya===
The family are a magus bloodline from Japan whose magecraft specializes in controlling water, allowing them to channel their mana into liquids and control them like mist.
The previous family head, Tsukumo Fujimiya's mother, had been summoned to help repurpose magecraft weapons for , but she refused. This caused her whole family to get eliminated, leaving only Tsukumo as the sole survivor, as she had been away at the time. Her dad, who had been away for the war, died during his duties, but it is unknown if the Imperial Japanese Army had anything to do with it. Tsukumo is the head of the Fujimiya family, who goes down a path of constant decline with each generation. Through the connections of her predecessors, Tsukumo managed to obtain an invitation to the Holy Grail War from the Holy Church.
Tsukumo's son, Kanata's father, didn't inherit her magecraft, and thus the Fujimiya's lineage of magi ended with Tsukumo. However, Tsukumo's grandchildren, Kanata Akagi and his younger sister, are capable of using magecraft, though Kanata is a mediocre magus who can merely decrease the speed of any object he touches, while his sister who apparently had potential and talent, separated herself from their family and became a freelancing magus.

If you want it, then take it. If there's a blade in your hand, then swing. That line of thinking is how the Galliasta family had risen to prominence. The successor to the family is decided by pitting siblings against each other in a number of trials meant to curry political power.

The heir to the family, Leonardo B. Harwey, was conceived between the former Harwey head and Leo's mother Alicia. While Leo is the younger brother of Julius B. Harwey, Julius is an illegitimate son, and after being harshly tested as a child, was discarded as a potential heir. Determining the Holy Grail to be a threat to their regime, the Harweys sent both brothers to the moon in order to claim it: Julius with the purpose of eliminating those that would oppose Leo, and Leo to take the Grail for the group.

Although one could say they are compensating themselves with modern science as their Magic Circuit lineage has been losing it's power it once had.
The family head, Shizuri Isemi, participates in the First Tokyo Holy Grail War as the Master of Rider, using Nefertari's necklace as a Catalyst, much to Rider's fury, as he is under the impression that the tomb of his most beloved wife was broken in and the necklace was stolen just to summon him.Fate/Prototype: Fragments of Sky Silver Volume 3: Beautiful Mind Arc - Act 4 Part 1

Quart, another member, can paint surfaces just by waving his hand over them, by manipulating the color, viscosity, transparency, and durability of his skin. Gray speculates that his multicolored hair is also an extension of this, since hair, skin, and nails are part of the same system. Quart also excels in using his skin to dissolve objects, like touching a wall to make it lose rigidity like a block of sugar soaked in water.

The were a family well-noted for their Alchemy. In the family, the first principle they are taught is "Magecraft is as strong as what occurs in the body."Lord El-Melloi II Case Files Volume 1: case. Adra Castle Separation - Chapter 2 Part 3
Originally, the current head of the Istari Family and his wife held high hopes for their firstborn son, Heine, to succeed due to his immense talent and skill as a magus. However, he later caused a scandal within the Clock Tower due to him abandoning his family, titles, inheritances, Magic Crest and position within the Clock Tower to join the Holy Church.
This in turn caused his parents to resort to implant their Magic Crest into their second child, Rosalind, at an incredibly young age that could potentially damage her body. Hearing about this, Heine returned in order to save his sister. However, by the time he returned to the family to retake the Magic Crest, his parents had already implanted the majority of the Magic Crest into her body and had damaged her internally, halving her overall lifespan.

===Kuruoka===
The are a magus family from eastern Asia associated with the government organization of America that is responsible for the True and False Holy Grail Wars of Snowfield. They acquired some of the mechanics behind the Holy Grail War and part of Zouken Matou's system of entomancy. They began to adapt it to their own use with the goal of developing a new way to modify the flesh with even smaller bugs, after much trial and error, they came of with pseudo-entomancy in the form of magically-modified bacteria meant to be instilled within a young magus to amplify their Magic Circuits as they grow.Fate/strange Fake Volume 1 - Prologue V: "Rider"
In the past, searching for a way to beat the Makiri's entomancy Magecraft, Yuukaku Kuruoka collected some microorganisms near some ruins in South America, surprised to find them so mystically compatible with humans. Unsure of whether they were a remnant of evolution that took place in the Age of Gods or if those microorganisms had a completely different origin from normal Earth species, Yuukaku was unable to develop them from scratch but did find a way to modify them and adapt them to his family's Magecraft. He then caused the microorganisms he'd modified using Magecraft to enter into a symbiotic relationship with his daughter Tsubaki Kuruoka's Magic Circuits.Fate/strange Fake Volume 6 - Interlude: "A Mercenary is a Free Man I"

===Lusendra===
The family are a clan of magi specializing in Reinforcement Magecraft, originating from the far north, they are said to have discarded even the concept of humanity.Fate/strange Fake Volume 3 - Prologue VIII: "The Star Performers' Feast (Part 1)"Fate/strange Fake Volume 4 - Chapter 10: Day 2: Day 2 "Separate Mornings, Separate Pasts I" They determined that one of their end goals was to replicate an allegedly extinct Phantasmal Species from Japan, the Oni, with their own flesh and blood, and spent the past 1000 years modifying their own bodies and Magic Circuits.Fate/strange Fake Volume 8 - Bridge Chapter: "Puddle"
With a special form of Reinforcement Magecraft passed down in the family, they repurpose their skeleton, each muscle fiber, each nerve, each lymph duct, and each capillary vessel to pass as a makeshift Magic Circuit. Their final destination is defined by the contradiction of making the already lost past reach the distant future. To take hold of, understand, or rewrite what is lost with the progress of the current form of Human Order, many magi keep the engine of their bloodlines running.
The Lusendra lineage has been in rapid degradation in recent years, not because they've been getting any less Mystery, but simply because they tried too hard. They devoured everything they could to grow closer to the phantasmagoria of the Oni, or to live life the way they did. The previous family head, the most powerful in their history, devoured man and fiend alike, sometimes even Vampires, and lastly, in an attempt to devour a God, he headed to Japan, where the God Possessor clans are. And there he randomly came across the real deal, which means to say he was slaughtered by a one-eyed man with thick Oni blood in his veins.
They lost most of their Magic Crest and then had to deal with the heavy consequences of their quest for "sacrifices to devour" continuously making larger amounts of new enemies for them, the only options left for them were to disappear into obscurity or to be instantly ruined by an enemy attack. That's when Doris, the only one who hadn't given up yet, was visited by Francesca Prelati and invited to the Snowfield Holy Grail War.

The current head is Lord Karmaglyph Meluastea Deluc.
Their bloodline's origins lie in the (the historical one, not the surviving Magecraft branch).The Adventures of Lord El-Melloi II Volume 5: Legacy of the Alchemist (Lower) - Chapter 2
The Meluastea's Department of Archaeology has always been in constant poverty for its entire history, but its sheer authority has always kept the Meluastea family at the very top of the Neutral Faction even without the money to back it up.The Adventures of Lord El-Melloi II Volume 4: Legacy of the Alchemist (Upper) - Chapter 1 However, the Department has been on the rise ever since Karmaglyph became Lord.The Adventures of Lord El-Melloi II Volume 5: Legacy of the Alchemist (Lower) - Chapter 3
While the Meluasteas were famous for being quite the softies despite being Lords, Karmaglyph’s actions are quite ambitious. Money was always necessary for Archaeology, but come the 20th century, money suddenly became exponentially more needed by everyone. The Meluasteas were the leaders of the Neutral Faction, but the Eleventh Department was always among the weakest. Their leadership status was symbolic and held together by tradition. Karmaglyph knew that and this was why he was so invested in solidifying his position.
A large part of the family's debt is owed to Melvin Weins' mother.
Their name is similar to , a Clock Tower Lord who lived in the 16th century.Fate/Grand Order: Cosmos in the Lostbelt - Nahui Mictlan: Golden Sea of Trees Travelogue - Prologue Any connection between Astea and the Meluastea is currently unknown.

Despite their insular and unsociable nature, the Einzbern reluctantly formed relationship with other magi, which the Musik family took advantage of in order to obtain a portion of their Homunculi craft. However, what the Einzberns taught was merely the equivalent of giving a toy to a child, so it was not much of a problem for them. While Musik family concealed the fact that they were part of the Yggdmillennia clan, the Einzberns had already known the truth.

The tradition and culture has been lost in the age of modern medicine, but the Sakatsuki still continue the practice of revering children as divinities.
The Sakatsuki's Child of God can grant the power of wishes unconditionally, though it is uncertain if the Child of God wish granting abilities is based on the age or Fuyuki's magical Leylines.

Kuchinawa just outside Tokyo.The Adventures of Lord El-Melloi II Volume 3: The Devil of the Wandering Sea (Lower) - Chapter 2
The Yakou follow the God Ōkuninushi.The Adventures of Lord El-Melloi II Volume 3: The Devil of the Wandering Sea (Lower) The name Yakou means “night eon”. In simpler terms, it signifies an endless night. And as this name suggests, their God’s nature is intimate with the Japanese underworld. To pay respect to their God, all members of the organization wear black.
They have deep ties to gambling dens, and because there's little to no need to protect people from fiends in the modern day, managing the gambling houses has now become their main activity.
Incest is not uncommon in the Yakou so they can thicken their special blood with the inbreeding. Father-grandfather, uncle-niece, and father-daughter marriages have all occurred.
Although limited to a few locations, their Boundaries are extremely vast and they have powerful techniques that can be used only within their Bounded Field, thus giving them unparalleled defensive power.
The Yakou use magecraft the way it was done in the Age of Gods. The Yakou magecraft uses kashiwade to call on kami (kami in this context referring to Od, the energy in all living things) to resonate with the opponent's individual wavelength. With this they can do things such as shaping Magic Formulas inside the opponent's body, essentially detonating a bomb inside of them.The Adventures of Lord El-Melloi II Volume 2: The Devil of the Wandering Sea (Upper) - Chapter 2 Part 4 They also use kagura masks crafted by the Tobori family to perform rites for their magecraft.
Japanese Magecraft is performed by connecting to fragments of Gods called , which are fully-formed organs of Gods. There are only eight known Divine Bodies in Japan, and in order to keep their Mystery from fading the eight groups that hold them have different ways to keep them safe. The Yakou store Ōkuninushi's Divine Body inside of a human being known as a .The Adventures of Lord El-Melloi II Volume 2: The Devil of the Wandering Sea (Upper) - Chapter 3 The number of people directly contracted to the Divine Body is slightly short of 100, but that only makes them the third biggest magecraft force in Japan at best.
As an aside, the Yakou family used Muramasa swords not because of their Mystery value but because Muramasa made the most combat-practical katanas. The fact that their Mystery eventually came to surpass their practicality with the passage of the years was a kind of ironic surprise.

===Zemlupus===
The are a family with a relatively weak history and short bloodline. With the family being stated to only be a few generations old and their Magic Crest only being two hundred years old. The Zemlupus family magecraft is anti-beast, meant for fighting animals. Their specialty is on the verge of obsolescence because humans can now track and kill beasts with mundane means, but in the past anti-beast magecraft was very useful for humans to protect themselves from dangerous animals.Fate/Grand Order: Cosmos in the Lostbelt - Traum: Life and Death of a Certain Fantasy - Chapter 1: The Coffinmaker is My Only Friend
However, despite their Anti-Beast magecraft no longer being very useful in the modern world due to it becoming obsolete to modern day weapons and techniques, the Anti-Beast magecraft of the Zemlupus family still had strong merit in the World of Magecraft. This is stated where the Beast Magecraft of Svin Glascheit and the Snake Magecraft of Roland Berzinsky were stated to be weak to it in a fundamental-conceptual level and made members of the Zemlupus family their worst opponents due to the natural advantage their magecraft had over theirs, forcing them to avoid fighting them and negotiate a peaceful resolution with a member they did encounter.

Having declined for several generations, their final head Heinrich Zepter became a heretic by creating monstrous fusions of man and beast in a fashion none too dissimilar to Mary Shelley's Frankenstein. After fleeing to Present Mountain, America, he was hunted down and killed by Natalia Kaminski and Kiritsugu Emiya. The Zepter family's Magic Crest was destroyed at this time by Kiritsugu, erasing the secrets of their magecraft.
