There was a very large Holy Grail War in the past, also known as World War III. The war took place internationally 14 years before Fate/Requiem and was said to be the greatest war that killed an unstated amount of humans and Servants involved, and no countries came out unscathed. The war also caused many parts of the world to be reduced to ruins and the water level rose greatly. Ocean lifeforms are said to have sharply decreased as well.
In the leadup to the war, over thirty Holy Grail Wars of various sizes were concurrently primed and ready to begin. Initially, the Holy Grail Wars were held in secret but before long the increasingly tense conflicts between countries and terrorism flung the gates opens and the Grail Wars ran rampant in the open. By the time people around the world learned that World War III began to nurture an innumerable amount of Holy Grail Wars, they were already past the point of no return. The first battleground of the war was Cape Canaveral in Florida, where NASA's space center was located. Now it is a wasteland filled with craters.
It was said that over 10,000 drones were deployed during the war's peak. The drones also came in various sizes and are not limited to flying ones, as drones shaped as ocean lifeforms did exist and contributed to the reason why ocean lifeforms are greatly reduced. The drones were so numerous and caused so much damage that for the generation that lived through the war, they have become something horrible that is not to be talked about.
Fuyuki was one of the fiercest battlegrounds, but the scale of the ritual must have been inferior to other battlefronts. Due to the fierce battle, the final winner was unknown, the ritual was not completed, and the accumulated magical energy from the Holy Grail dispersed.
The victors of the Holy Grail Wars in various places repeatedly moved to different battlefronts, aiming for greater heights, more fighting. They fought in muddy battles to possess the Holy Grails that others had won. Chitose Manazuru, also known as the Stigmata, put an end to that by choosing to settle it in a similar manner to a tournament. Chitose and her Servant Lucius Longinus were the victors. Chitose asked to the wish granting Holy Grail to persist and distribute itself, becoming Grails in the hearts of humans, terminal devices of the Stigmata.
The world is said to have become peaceful after it ended. Tokyo is now a dead city inaccessible to many, referred to as "Netherworld Tokyo." The various wards of Tokyo such as Akihabara, Shinjuku, and Shibuya were restructured by the Holy Grail into Mosaic City, where the survivors of the war gathered. The world outside of Mosaic City, both the land and the sea, is a wasteland.
When a human is born, they would automatically have a Holy Grail located in their heart, but it does not immediately mean Servants will be summoned to their Masters, and some may take years for it to actually manifest. Civilians of the Mosaic City do not have the choice and are granted a Servant regardless of their will. The Holy Grail would assume a citizen's wishes from deep inside their heart and pair the Master with the Servant of the closest compatibility. While most of the people may be happy or indifferent to have their own Servant, some do hate or even flat out reject Servants.
Multiple "copies" of the same Servant can be summoned. For example, there is a musical group comprised of five separate Elizabeth Báthorys.
The new generation of humans will not die of old age or sickness, though can still be murdered. Everyone has Command Spells that can be used to change the physical age of their bodies or activate their Servants' Noble Phantasm, and the strokes of the Command Spells regenerate over time. Chitose Manazuru is the only person left who still has the old style of Command Spells that disappear for good once used.
Some pre-war individuals were involved in incidents where a Servant had killed their family during the large War, so they have Servantphobia (サーヴァント恐怖症?) that makes it fundamentally impossible to manifest the Servant granted by the Holy Grail.
In the post-war world where Servants have become commonplace, more care is being paid to improving their quality of life. There are even some citizens’ groups that insist that they have a right to live the same as humans. It is not uncommon to see Servants as employees or even running businesses themselves.
Due to the situations of this world, Mystery is largely exposed (though not entirely, and the Mage's Association still exists), and magecraft is common knowledge, though just like in the world before not everybody has the capacity to be a mage. Because the majority of Masters are not mages, the majority of Servants are weaker than normal. The magical energy supplied by the Holy Grail can be used for simple magecraft and is more than enough to sustain a Servant in everyday life with no discomfort. However Noble Phantasms are another matter entirely: activating them is highly challenging, often requiring a Command Spell, and using one could kill a Master unless attempted with extreme care. The exception to this is in Akihabara's Colosseum, which is designed to siphon magical energy from the thousands of people in the audience, allowing for competitors in the Grail Tournament to fight at their best.
The survivors of the war have worked hard to try and recover the culture that was lost, such as bringing back holidays from the world before the war. However these holidays are mere replicas and aspects of them have been lost or changed, and the new generation born after the war doesn't quite understand how they used to be. Some adults are surprised when the younger generation can recognize things like CDs, though it's also fashionable for young people to walk around with an MP3 player.
The story takes place 56 years after Neil Armstrong landed on the moon.
Holy Grail War
"After" the Holy Grail War
The current day is described to be fifty-six years after the first Moon landing.
Servant Loss is a phenomenon that begins after the summoning of Voyager, the "last Servant summoned into the world." Servants that would normally be summoned upon the birth of a child no longer happen, and Masters who have lost their Servants are no longer able to be granted a new Servant by the Grail.
Holy Grail War Tournament
Holy Grail War Tournaments (聖杯戦争トーナメント?) are battle tournaments held for sport in Akihabara. There are both individual matches and team matches. Circe is the tournament's emcee, and Blackbeard and Agrippa are commentators. Euclid was going to be as well, but cancelled at the last minute.
