The Atlas Temple (アトラス院, Atorasu-in?)[1], Atlas Academy, or Atlas Institute is one of the three major branches of the Mage's Association specialized in Alchemy. It is also known as the Titan's Pit (巨人の穴倉, Kyojin no Anagura?) and the Institute of Aggregation and Analysis (蓄積と計測の院, Chikuseki to Keisoku no In?).[2][3][4][5][6][7][8]


This organization is simply named after the Atlas Mountain where it is located and Holmes suggests that their other name, Titan's Pit, comes from the Titan Atlas in Greek mythology pointing out their duties are same in some way. The alchemists of the Atlas Temple are descended from the goddess Isis, the ancestor of magi in Egyptian mythology. Its appearance in this Egypt may be thanks to that connection.[8] The Atlas Temple predates even before the Clock Tower.[5][7]

It was an organization of alchemists that conducted inquiry (解明, kaimei?, lit. "elucidation") into the basis of Magecraft (魔術の祖, Majutsu no So?, lit. "the forefathers / origins of Magecraft") and the Laws of the World (世界の理, Sekai no Kotowari?, lit. "the principles / rationalities of the World").[8] Atlas was responsible for measurement and prediction. They are more concerned about the greater truths of the universe than mainstream Alchemists.[3]

The Atlas Temple is an assembly of geniuses. In this place, there are no taboos and no penalties to prevent the creation of the most unethical of weapons. Their only one rule is that things which are created here must never leave. That is the founding principle of the Atlas Temple. They have observed this rule for over two thousand years. They feared people leaving more than they cared about visitors.[8]

However there are seven exceptions to that principle, ever since the founding of the academy; the Atlas Temple is bound to cooperate with someone who possesses one of seven contracts, which bind the Temple to render aid on demand. As of the year 2000, four contracts had been recovered, but the locations of the remaining three were unknown.[8]

External RelationshipsEdit

Ever since the Clock Tower became the headquarters of the Mage's Association, mingling between the branches has been on the decline.[5][7] For some reason they are on extraordinarily bad terms with the Prague Association, and even the Clock Tower, the very heart of the Association, keeps their distance.[2]

The most independent of the Three Great Branches, it has its own terms of relationship with the Holy Church and other magic organizations. Not surprisingly, these traits cause Atlas to be disliked by the Clock Tower and the Prague Association.

Atlas has a number of unique customs for a magic association. One of them is that, at times, the institute has been known to lent its alchemist to other organizations such as the Holy Church, although the particulars of the process dictate that the other party must possess one of the seven special contracts that Atlas has printed in the past. One of the organization's main concerns in the present is the recovery of said contracts.

The Atlas Temple provided central Pseudo-Spiritrons calculation engine to the Chaldea Security Organization, thus they were able to invent TRISMEGISTUS in 2015.[8]

Alchemist of AtlasEdit

Their Alchemy diverges from the modern practice of Alchemy (現代錬金術, Gendai Renkinjutsu?, lit. "modern Alchemy") that has since the medieval period entered the vogue.[2][3][8] The often spoke-up "transformation of base metal to gold" in alchemy is, to the members of the Atlas Temple, mere "transformation of matter" and is nothing more than a primitive art far removed from their ideals. Their alchemy is an advancement of the metallurgy of ancient Egypt, the root of the discipline, and has not been influenced by western magecraft like the alchemy that the Clock Tower magi handle.[6]

It was their belief that humans have evolved to gather information, analyze it and then directly solve any problems perceived. The Atlas alchemist possessed great calculation and measurement ability that is rare to manifest naturally in a normal human (and their five senses).[3] They specialize in thought partitioning and thought acceleration, techniques that make use of the human body as an arithmetic unit.[9] Following their mantra “Faster, Stronger, More Accurate” they treated their bodies as containers to fill and modify in order to develop their abilities.[3]

Their way of thinking concerning their body (flesh) is also unique. That is, they do not believe that the brain exists to control the body, but rather that the body exists solely so that the brain may function more effectively. If you just want a mathematical prodigy, there's no need for an alchemist – an engineer would do just fine. What sets apart an alchemist is that for them, the human body in its entirety (body, mind, and soul) is a unit for calculating, executing, and nurturing events.[9]

« We have no need to be the strongest. We create that which is the strongest. »

(That is a central dogma of the Atlas Temple’s alchemists.[8])

It seems that most of its members cannot perform Magecraft that goes along the line of nature interference due to the lack of Magic Circuits.[8][9] But they're perfectly okay with that. As far as they're concerned, there's no need to be strong themselves, because they can just make up for it by creating the strongest weapons.[9] Unlike most Magus, Atlas Alchemists special abilities were based on a Man and Machine approach.[3] They used the quantifiable energy of the Soul; the Pseudo-Spiritrons to engineer organisms with magic circuits such as Homunculi.[8]


It is an institute focused on the study and development of alchemy, but its members broke off from the mainstream modern practice of alchemy that originated in the Middle Ages.[3] However, the ultimate goal of the alchemists of the Atlas Temple is set even closer to the original ideology, as the "transformation of events".[6]

Members of Atlas utilize a method of prediction based on Laplace's Demon. After its first director theoretically predicted the end of the world, the alchemists of Atlas have dedicated themselves into developing methods capable of avoiding it. However, because anything potentially capable of preventing the end of the world might also create even greater devastation, eventually rules dictating that everything created in Atlas must be kept and disposed of within the domains of the organization were established.


Accordingly, the process they used to study mysteries did not depend on Magical Energy. Instead, they relied on a great many tools. Atlas’ development was similar to the progress of science and technology.[8]

Following this principle, Atlas has birthed a great arsenal of weapons.[8][9] In order to avoid the "end" proven by their first director, they endlessly create and dispose of weapon after weapon. The reason being that the weapons created there to save the world are ultimately nothing more than tools that will further its destruction.[2]

Seven SuperweaponsEdit

The Seven Superweapons of Atlas (アトラス院における七大兵器?) are seven weapons on display at Atlas. There is a saying in the Prague Association: "Lift not the seal of Atlas, lest ye destroy the world seven times over."[2]

Known weapons


HERMES (ヘルメス, Herumesu?) is a sixth generation computing unit based on the Pseudo-Spiritrons particle theory that shouldn’t even be completed and exist in this world yet. Hermes is the crystallization of the Atlas Temple’s innermost secret techniques of fundamental Alchemy. We can assume that this is probably the Philosopher’s Stone.[11]


The TRI-HERMES: The Pseudo-Spiritronic Processor (疑似霊子演算装置トライヘルメス, Torai-herumesu, Giji ryōsi enzan sōchi?) are Atlas Temple’s greatest storage media, in the form of obelisks. Chaldea's TRISMEGISTUS is nothing more than a copy of this, the construction is same as the control room in Chaldea. It is photonic crystal, which has even been called Philosopher’s Stone. It is an out-of-place artifact impossible for current terrestrial science to create.[8]

All events are recorded in TRI-HERMES, however only Atlas Alchemist has full access to TRI-HERMES.[8]


  • Atlas Temple (アトラス院, Atorasu-in?)

It is located somewhere among the mountains of Egypt.[2][3][4][5][7][8] The Atlas Temple is an underground academy with full of mysteries. The Alchemist each have their own independent workshops, within which they conduct their research. Laboratories built with unknown technologies.[8][3]

There are storehouse for Mystic Codes, though it is considered to be no more than a junkyard. The Atlas alchemists invented many devices, deemed them failures, and dumped them into a terrifying mountain of weapons.[8]

The construction of Atlas is rather convoluted. There are tunnels that were deliberately designed to resemble an underground labyrinth. It's more like a labyrinth than an academy. It was designed to confuse anyone trying to get out. One can enter, but leaving is no trivial feat. They are filled with autonomous familiars defense systems. It may be the ideal shelter but it is little more than a mass grave.[8]

In the center of the academy, it is where TRI-HERMES is located. The core lies a distant 500 meters below the surface. Someone built such a massive cavern underground, where it is large enough space to contain a town. The core of Atlas has a man-made sky in this underground chamber.[8]

The Future of AtlasEdit


The only remaining old world Magus are the Alchemists of the Atlas Temple in Egypt.[12] The correctness of this idea was somewhat proven in the magic-devoid world of Fate/Extra. The Alchemists of Atlas have poor magic circuits, and did not lead their lives relying on magic. As they are Alchemists who did not rely on magic (or to be precise couldn’t rely on magic) even as the decline of magic circuits progressed, they could continue their pursuit and study of magic.

However, with the persistent death in the conception of children for the subsequent generation, and the successive suicides (自決死, jiketsu-shi?) of the veteran Alchemists, the Atlas Temple met with a destruction unassociated with the Mana Depletion. Within the Atlas Temple, there exists at present no more than a single Homunculus. The final Alchemist of Atlas died of illness after coining (鋳造した, chūzō-shita?) said Homunculus, letting to remain within the Cavern (洞窟, dōkutsu?) only her final creation. With the vanishing of the Alchemists, this underground city (地下都市, chika toshi?) that was complected entirely of research facilities (研究施設, kenkyū shisetsu?) built of technologies (技術体系, gijutsu taikei?, lit. "systems of techniques") as yet unknown has become as an immense mausoleum.[3]

Grand OrderEdit

The Atlas Temple of 2016 was removed from its original time period, causing a temporal aberration within the Egyptian territory in the Camelot Singularity. The Lion King has incinerated the magi of the Atlas Temple, but the academy itself remains. Zepia Eltnam Atlasia was the last director named in the Atlas Temple. It appears he had a successor but that person's name was not written. All the past directors have challenged the future, failed, and then went mad as they created forbidden doomsday weapons as a result.[8]

Known MembersEdit

They have a custom for the directors of Atlas to adopt the name of Atlasia during their time in office.

Pseudo-Spiritron Computer (疑似霊子コンピューター, Giji ryōshi kompyūtā?), also known as Virtual Spiritron Computer,
A supercomputer completed using Spiritrons created by the magical theory of Pseudo-Spiritrons. An apparatus capable of fast processing by defining the soul of the machine and making use of its Spiritrons. A parallel concurrent processor which mobilizes “something” in a Parallel world, mainly revolving around the soul on a higher plane. The first model was completed in 1980. Its processing power was equal in magnitude to the quantum computer which was planned to be completed in 2030 or greater (the quantum computer project itself was frozen in 1999 by the Western European conglomerate). It was with the backup of the virtual spiritron computer that the exploratory probe from the UN-led mission that humanity was able to infiltrate the moon. Aside from a direct invitation from the moon cell, it is also possible to “drop” into the moon with a cheap interface, so long as you give your consent, though what awaits you is a death game where those other than the victor cannot come back alive.[15]
