The roots of Fantasy Trees will fall. The signal from heaven shall be cut off. The plane on Earth turns into solid ice. This planet has already left alone. This planet will turn into nothingness after they filtrating the alternate histories and starting an invasion. The rightful order has been lost. There's no Hero Spirit that guards humanity. The allies will fade and die. In this world, YOU are the real Evil of Humanity! However, on the point of survival, there's no superiority or inferiority between good and evil. If all of you don't ever give up, just act like before. Even if everything turned into nothingness, you'll still desire its survival! Fools, screech with all your might! Be remorseless over the faulty you accumulate. Be in debt for your responsibility and eventually, fill your heart with hope. The battle for humanity is just begun.
~ Goetia (under the persona of Solomon) to the protagonist, prophecizing the war of the Lostbelts in the preview trailer of Cosmos in the Lostbelt.

The Lostbelts (in Japanese: 異聞帯) are supernatural alternate dimensions and the main setting of Fate/Grand Order: Cosmos in the Lostbelt.

The Lostbelts are considered by the world itself to be failed timelines. As opposed to the Greater History of Man, the history of "winners" born from correct choices and proper prosperities leading to the "present", the Lostbelts are histories of "failure" born from the wrong choices or false prosperity for humanity. Such is their nature of failure that they are even cut off from the greater multiverse.

The Lostbelts started to surface and establish themselves on earth itself after the Crypters allied with the Outer Gods and instigated an attack against Chaldea. The Crypters were seven former A-Team Masters who died in the attack of Lev Flaros, but was revived by someone presumably loyal to the Outer Gods.

Following the attack on Chaldea by the end of 2017, the freezing of the world, and the declaration of rebellion against the Greater History of Man with the threat of a regression into the Age of Gods and the recreation of the world, the survivors are forced to use an experimental method of navigating through imaginary number space to reach the Lostbelts and resolve the incident.

After all of the Lostbelts were established, the Crypters seeked to expand the "domain" of their own Lostbelts, which would eventually clash with the other Lostbelts. A world that is built by a greater Human Foundation will end up overtaking a weaker one and use it as "nutrients". This process will allegedly continue, until only one Lostbelt is remaining. Every Lostbelt has its depth, which means the scale of its deviation from the original history or mythology. Their existences are connected to the Fantasy Trees inside them.

Most humans died, and while Russians were used to the cold and prepared for such weather, 90% of their population perished and the survivors were on the cusp of extinction. Tsar Ivan IV, also known as Ivan the Terrible, and his mages were able to save the country by combining humans with magical beasts, creating a human-animal hybrid race known as the Yaga, with Ivan himself becoming the first.

He decided to bring about the Twilight of the World, killing many gods and giants before being sealed within a false Sun by Odin, who died afterward.

However, before dying, Odin merged the goddess Skadi with Scáthach, creating Scáthach-Skadi, the King of the Lostbelt, with the purpose of protecting the humans and ending Ragnarok before it could ever started. As Ragnarok was interrupted as a result, the world became ravaged by fire and ice, unable to continue past Ragnarok for the next thounsands of years.

Scathach-Skadi established multiple villages for humans, with the support of the Valkyrie. However, in order to keep the giants at bay, humans are required to reproduce at the age of fifteen. If they fail to do so, they shall be sacrificed to the giants, but once they reach the age of 25, they are nonetheless offered again to the giants.

Sin: Land of Unified Knowledge

Now becoming a mystic, Qin Shi Huang became the immortal ruler of the Lostbelt and developed incredible technology, placing every Chinese Heroic Spirit under his control and seizing domain of the world.

However, Qin Shi Huang had no intention to work with Outer Gods and decided to challenge them and fix humanity by himself, making his Lostbelt the one with the lowest depth compared to the others. The citizens of this Lostbelt lived peaceful lives as farmers untouched by war, but they were isolated from the Emperor's technological wonders.

Genesis Destruction Cycle: Yuga Kshetra

  • Formerly Known As: Genesis Destruction Cycle ■■ ■■■■■■
  • Subtitle: The Black Final God
    • Referring: Arjuna Alter (not featured on the banner)
  • Crypter: Scandinavia Peperoncino
  • Place: India
  • Time: ?.?. 11900
  • Servant: Archer (Ashwatthama)
  • Lostbelt King: Berserker (Arjuna Alter)
  • Status: Erased
  • Depth: A

The Indian Lostbelt was diverged in 11900 ?.?. at the "Cycle of Creation and Destruction". The bizarre date was originated from the Mahā-Yuga cycle which the fourth Lostbelt used as it's sole time measurement. Mahā-Yugas are composed of 12000 'Deva years' or almost 4.5 million years normally.

In this world, the gods of the Hindu pantheonnote fused together into one "perfect" deity, later revealed to be the Lostbelt version of Arjuna known as Arjuna Alter. As the Lostbelt King, Arjuna Alter speeds up the Yuga cycle to run it's course every 10 days in his desire to remove anything that could be considered "evil" from it, each cycle deleting elements from tthe world entirely with no chance of reincarnation. The cycle slowly reshaped the Lostbelt to Arjuna Alter's view of "utopia," with plans to extend it across the entire galaxy and then the universe.

The fusion of the predominant Hindu Gods had caused the Lostbelt to become nearly godless, resulting in the Lostbelt version of Kama, who managed to escape, to create a Singularity named Tokugawa Labyrinth. He later transformed into Beast III-L after being taken over by her inner evil, Mara, who became dominant since there were no god to oversee her.

Kirschtaria Wodime's Lostbelt

  • Subtitle: The Day God Is Shot Down
    • Referring:
      • Atlantis: Super Orion (shooting down Artemis)
      • Olympus: Chaldea Crew & humanity itself (shooting down the Olympians)
  • Crypter: Kirschtaria Wodime

  • Servants: Lancer (Caenis), Saber (Dioscuri Twins), and Atlas
  • Lostbelt King: Ruler (Zeus)
  • Status: Erased
  • Depth: A+

Kirschtaria's Lostbelt, also known as the Atlantic Lostbelt and the Greek Lostbelt, has the largest scale of all seven Lostbelts and 80% of its surface is covered by Fantasy tree roots. It diverged from proper history in 12,000 BC, taking place around the same time of Fate/Extella: The Umbral Star, where Velber arrived in the Solar System and ordered Sefar to slaughter the original God Concepts, the Twelve Pillars, beginning the decline of the Age of Gods. However, this world's Gods triumphed over Sefar and continue to reign supreme over humans to this day.

Kirschtaria has three Divine Spirit Servants under his command, including Caenis, who are supposedly some of the most powerful servants summoned by the Crypters. Kirschtaria is on good term with Zeus, the Lostbelt King of the Olympian Gods.

Atlantis: Ocean in the Age of Titans

The first part of Greek Lostbelt is in the form of a giant ocean city where the Age of Gods is described to have proceeded into the present, the gods in question being the ancient Greek Gods. In this Lostbelt, it was implied that Poseidon perished and new forces began to rise in order to take his place.

Olympus: Interstellar City Mountains

The Lostbelt version of Mount Olympus is the real center of the Greek Lostbelt, where the Olympian Gods and where the fifth Fantasy Tree resides. In this version of Mount Olympus, the Olympians managed to defeat Sefar and maintained their rule. When Zeus decided to expand the Age of Gods to further their reign, Hephaestus, Hades, Athena, Apollo, Hestia, Ares opposed him and got destroyed in the resulting war. Zeus survived alongside Artemis, Poseidon (at the time still active), Demeter, Aphrodite and Hera, and continued to rule the world. They advanced their powers and technology to the point where they redefined the concepts of Gods and fully became machines, with powerful divine nanomachines being used as Authorities.

Its Fantasy Tree, named Atlas, is a completely matured Fantasy Tree resides within the Greek Lostbelt. However, it is revealed that Kirschtaria hides his final Divine Spirit Servant, the Titan Atlas, within the aptly named tree for failsafe. By the end of the Olympus chapter, the Alien God brings the Fantasy Tree out of the Greek Lostbelt for unknown purposes, subsquently dooming the Greek Lostbelt for good.

Round Table Territory ■■■■■■■■■

  • Subtitle: The Day the Star is Born
  • Crypter: Beryl Gut
  • Place: Arthurian Britain
  • Time: 500 A.D.
  • Servant: Assassin (unknown)
  • Lostbelt King: Unknown (presumably a version of Artoria/Arthur Pendragon)
  • Status: Crumbling
  • Depth: EX

The sixth Lostbelt, where Beryl resides, is a world centered around Britain, which diverged during 500 AD within the "Round Table Territory". The inner workings of his Lostbelt are still a secret to all. According to Kirschtaria, the British Lostbelt is something that by nature simply doesn't "fit" the planet, and so it's Difference Depth cannot be measured, hence the EX rank. It apparently contains something capable of threatening the Alien God.

By the time when Chaledea crew is heading towards the Atlantic Lostbelt, however, Beryl already manipulated this Lostbelt's Round Table Knights to chop down its Fantasy Tree and fled, leaving this Lostbelt crumbling. However, for some reason, the British Lostbelt still seems to exist, with its edge still visible, even though by no doubt it is falling down slowly.

According to Beryl, a "little princess" is also in charge of operating this Lostbelt. Somehow, she is not bothered with Beryl's true identity as an espionage, only flirting with him and trying to have fun with him. Her troubling behavior made even Beryl himself, a sociopathic killer, so afraid that he scramed himself out of the Lostbelt.

■■ Forest ■■ ■■■·■■■■■

  • Subtitle: Unknown
  • Crypter: Daybit Sem Void
  • Place: South America
  • Time: Unknown

The seventh Lostbelt where Daybit residing is located somewhere in South America and diverged sometime during the B.C. era. The inner workings of Daybit's Lostbelt are still a secret, but it is close to collapse because its version of humanity is nearly extinct. There is somehow no sign of a Fantasy Tree being detected.
