Greater Holy Grail of Fuyuki

The is the Greater Holy Grail of the Fuyuki Holy Grail War. Designed to reach the Root, it is a system that has been designated as a Holy Grail for the purpose of serving as the foundation of the Holy Grail War system.
==History==
===World of Fate/stay night===
In the World of Fate/stay night, during the Third Holy Grail War, the Einzbern messed with the system of the Grail and summoned the Avenger-class Servant Angra Mainyu, and after his defeat in the 4th day of the war, the Holy Grail was corrupted with "All the World's Evils".
In the Fate and Unlimited Blade Works routes of Fate/stay night, ten years after the Fifth Holy Grail War, the Mages Association planned on bring back the Greater Grail with great opposition from the Church. After the end of a great turmoil with the same magnitude as the Grail War, the Holy Grail in Fuyuki City was dismantled under the direction of Lord El-Melloi II and Rin Tohsaka and the Grail Wars of Fuyuki came to a complete conclusion. In the Heaven's Feel scenario, the Greater Grail is either finally destroyed by Shirou Emiya (normal end) or shut down for good by Illyasviel von Einzbern (true end). In the case of Heaven's Feel, a dismantling would still take place, but it would be more akin to a removal so it can never operate again. A device that can change the world isn't just gone after breaking apart, a cleaning up that is just as much work as the creation process is still needed.
===World of Fate/Apocrypha===
In the World of Fate/Apocrypha, the Third Holy Grail War failed due to the destruction of the Lesser Grail. Furthermore, the Greater Grail was stolen from Fuyuki by Darnic Prestone Yggdmillennia with support from Nazi forces, who intended to use the Grail as a weapon to win World War II. The Three Families tried to stop the theft, but they were hampered by exhaustion brought about by the War's fighting.Fate/Apocrypha Volume 1: Apocrypha: Great Holy Grail War - Chapter 1
However, Darnic betrayed the Nazis and disappeared with the Grail to Romania, where he spent the next sixty years preparing a Holy Land suitable for a Holy Grail War. Ultimately, he was successful in establishing himself as the leader of the Yggdmillennia clan and starting a War.
===World of Fate/Grand Order===
==Characteristics==
The Greater Grail is the gateway linked to the Root and the ultimate prize for the Fuyuki Holy Grail War, and is in essence, a wishing machine. Known as the core world, the , the core of the Grail was formed by Justeaze Lizrich von Einzbern, who continues to remain at its centre. The creation of the Great Grail was done so under the supervision of Kischur Zelretch Schweinorg, the teacher of the three founders of the war, Justeaze, Makiri Zouken, and Nagato Tohsaka.
The magic circle of the Greater Grail is inscribed upon the land managed by the Tohsaka family in Fuyuki City. Located in the great cave underneath the Ryuudou Temple on Mount Enzou, it consists of a series of seals carved around above 50 meters of bare rock. It is the most ideal location for the Holy Grail to be summoned, though three other locations also exist should the location at Mount Enzou be unavailable: the Tohsaka residence, Fuyuki Church, and Fuyuki Central Park. The Greater Grail itself is a system, and the Holy Grail is the key to start it up. The Greater Grail does not have a will and Justeaze’s soul was completely sublimated when she sacrificed herself for the ritual. While the Holy Grail collects the souls of the Servants, the Greater Grail uses the energy to open a gateway. Though the Lesser Grail is forcibly destroyed by Saber under the command of her Master, Kiritsugu Emiya, its corrupted contents spill from the Greater Grail in the form of black mud.
For the Holy Grail Wars, the Greater Grail is what selects the Masters and invites Heroic Spirits, setting them in the Servant class system. After picking a Master from each of the three founding families (the Einzbern, Matou, and Tohsaka), it preferably picks Masters who earnestly want it, although it is possible to have irregulars, like Kirei Kotomine in the fourth Holy Grail War, who has no sense of purpose except seeking destruction and evil acts.
Depending on the situation, the Greater Grail could support the Holy Grail War by once again distributing Command Spells. A reserve system of the Grail can be activated to allow for the summoning of seven other Servants, this was an auxiliary prepared as a countermeasure for the highly unlikely situation of all seven Servants joining forces. Basically, summoning another seven Servants to oppose the original seven Servants.
In Fuyuki, such a system would certainly have been an emergency measure, if worst came to worst, such an act might even have exhausted the leyline itself. However, the land of Trifas is positioned on the best leylines of Romania to begin with, quite likely having been stockpiling prana at a higher speed than Fuyuki, to the point that it now possessed an inexhaustible amount of prana with which it can summon even fourteen Servants.
===Wish granting===
It is, however only a clump of magical energy and thus is not as omnipotent as people believe it to be, so wishing for something like "Saving the World" without specifying a working method will not suffice. Even if someone lacks power or wealth, the Grail can possibly carry out such a wish if they knew "the method of Saving the World." Kiritsugu Emiya, knowing only the practice of "sacrificing few for the benefit of many", was shown such a vision of "what would happen if the World was saved", though the corruption caused him to be shown the most malicious imagery of his "saved world." Had he followed through with it, the Grail would have certainty done as it showed him. Ultimately, it can only amplify the scale of realization of wishes within working methodologies and is incapable of granting true miracles.
===Pathway to the Root===
Servants that get killed return to being a "piece of energy" and disappear from the time axis, but the Grail (container) created by the Einzberns is here to temporarily stop that and store them. When the Holy Grail goes into hibernation, it puts its accumulated mana into storage. When 7 Servants are present, their spiritual cores will be released, and the Heroic Spirits’ bodies will disappear from this world. The cores alone will then return to the Throne of Heroes. Once the vessel is filled with energy, the Greater Grail can start the ritual that will open a "hole" to the Root.
To open a way to the swirl of the Root, the Grail needs to sacrifice all seven Servants to start up the Greater Grail, but six Servants are enough if the wish is within the limits of the world.
===Corrupted Holy Grail===
The essence of its content is a "colorless force", but after the third Grail War, it has been polluted by Angra Mainyu and became a malignant "swirling power", a curse, the third element. Hence, it is absolutely impossible to correct inconsistencies by precise calculations or interactions, and it will interpret any wish of the owner with nothing other than destruction, and grant it. Moreover, once it has been opened, it will keep flowing out infinitely and bring disaster.
The servant who is known as Angra Mainyu was summoned in the Third Grail War, was a Heroic Spirit born into existence according to people’s wishes. As a result, Avenger was born into this world in order to grant everybody’s desire for an existence like “All the World’s Evil”.
Even though the Holy Grail War would happen every 60 years, the 10-year gap between the Fourth and Fifth Holy Grail Wars was shorter because the Lesser Grail was destroyed before the Greater Grail could direct the accumulated mana to establish its pathway, with the unused mana becoming trapped in the Grail. The function of the Greater Grail was also already disrupted when it was corrupted with Avenger in the Third War.
Additionally, since the corruption, the Grail has been able to summon evil-aligned Heroic Spirits; something that was not allowed before. Heroic Spirits are humans whose legends are passed down in the memory of humanity, regardless of their alignment; the Grail originally was allowed to summon only "good" Heroic Spirits, but ever since the corruption, spirits like Gilles de Rais, Medusa and Medea can be summoned despite being anti-heroes (or outright villains) rather than heroes in the common understanding of the term.Fate/stay night - Unlimited Blade Works route - Day 13: VS berserker - Interlude 13-1: PrincessFate/Zero Volume 4: Flames of Purgatory - Act 14 Part 4 -36:38:09
The classes are, however, unaffected. The summoning of Avenger was a mistake done prior to the corruption, and the corruption itself had no known influence on the classes. It seems that it is only a coincidence that the two known Casters have an evil alignment.
This power also gives birth to , Angra Mainyu. While it is weak compared to the maelstrom of Magical energy that is the Einzbern Grail, what it can do is grant wishes. In a way, it is a small but "true" Holy Grail. It is the foundation of the looping world in hollow ataraxia, where it appears as a black moon, hence the name.
