User blog:Inept Wiki User/Lost Belt No. 1: Anastasia, Information and Speculation

It is just over a week before the first chapter in Cosmos in the Lostbelt is released. With Anime Japan 2018, promotional materials and a short CM have been released, giving us a fair amount of new information to speculate about, with more to follow.

I had been gathering information and speculation from the post-Prologue period in a previous blog entry, however I was having difficulty with the compilation and referencing, as well as making it a bit less messy, and I don't think I'll be finished with it in time for the release. Therefore, I thought it might be better to separate the information from the immediate pre-release period and post-release period for Lost Belt No. 1: Anastasia and put them on a new page.

Given the situation with the previous page and external circumstances, initial construction here may take a little time as well. Fortunately, there is less information to process at the moment than for the previous period. If there's anything to add or amend, please say so in the comments below - it'd be much appreciated.

WARNING: Spoilers below for those not following the Japanese release of Fate/Grand Order





For information and speculation in the period following the Second Prologue and before the immediate pre-release period for Lost Belt No. 1, see Cosmos in the Lostbelt: Post-Prologue, Pre-Anastasia Information & Speculation

Previous Events
On December 31st, five days after the arrival of Chaldea's new director, Goldolf Musik and after a period of interrogation for the previous staff, it was discovered that an unknown party had secretly removed the former members of Chaldea's A-Team from their coffins, where they had remained in cold sleep since being injured by Lev Lainur Flauros's bomb, and left a decoy signal in their place. Immediately afterwards, contact was lost with the outside world and Chaldeas reported that all other celestial bodies had vanished from the sky.

The facility then came under attack from the Oprichniki, led by Anastasia, a Servant from the Lost Belts, and aided by two infiltrators, Koyanskaya and Kotomine. The invaders made short work of Goldolf's mercenaries and began hunting the remaining Chaldea staff. In a weakened state, at a huge disadvantage, and with the facility being frozen and rendered uninhabitable, the survivors made their escape from Chaldea in the Shadow Border, a vehicle constructed in anticipation of this situation. During the evacuation, Da Vinci was ambushed and killed by Kotomine, though she delayed him long enough for the others to escape.

Driving across Antarctica, the survivors (Fujimaru, Mash, Sherlock Holmes, a back-up copy of Da Vinci, Goldolf and 8 other staff members) witnessed several meteor-like objects descending from the sky on an abnormal vertical trajectory. They then heard a broadcast from Kirschtaria Wodime, former leader of Chaldea's A-Team, who declared a rebellion against the Greater History of Man, which he deemed incorrect. Calling himself the representative of the Crypters, seven Apocryphal Leaders chosen by seven seeds with the descent of gods from distant skies, he declared that they would remake the world, filling it with Mystery once more and returning it to the Age of Gods, with the old humanity frozen and brought to an end as of 2017.

With the Oprichniki overwhelming the coastline, the survivors were forced to dive into Imaginary Number Space in order to escape. At the time of their escape, humanity and the world of the Greater History of Man had been frozen, the surface bleached white and the planet now isolated, all other celestial bodies having vanished from its skies. It was left a blank slate, one which the forces of the Lost Belts intended to create a new world upon.

Current Situation
As of the beginning of this chapter, the Shadow Border has surfaced after being in Imaginary Number Space for three months, and the fight has begun to take back the world from the forces of the Lost Belts, among them the former members of the A-Team, the Crypters.

Following the battle to restore history and reclaim the future, a battle to overcome alternative histories and many futures begins...

Setting
The is the first of the seven known Lost Belts being featured in this chapter is Permafrost Empire Anastasia (永久凍土帝国 アナスタシア), alternatively Princess of the Land of Beasts (獣国の皇女) and Lost Belt No. 1 (ロストベルト No. 1). It's Lost Depth is D and it's associated Crypter is Kadoc Zemlupus. The events in it apparently occur in 1570 AD, which was when the happened.

Opening and PV Information
The scenery glimpsed in the opening and PV was comprised of mountains covered in snow and in the grips of blizzard. A castle was also featured in the opening behind Anastasia.

Figures
With the exception of Koyanskaya, all of the enemies who directly participated in the assault on Chaldea are confirmed to be appearing in this Lost Belt, along with several other key individuals.

Crypter: Kadoc Zemlupus
The Crypter associated with this Lost Belt is Kadoc Zemlupus. As with the others, he is a former member of Chaldea's A-Team, who now stands against the survivors as a Master working with the forces of the Lost Belts to remake the world.

Kadoc's circumstances have been described as similar to Fujimaru's, being an average magus but possessing high Rayshift compatibility. Da Vinci described him as a youth with a gentle smile but with somewhat masochistic tendencies, timid but a mythology nerd and an avid reader. Mash described him as someone who pays attention to his surroundings but is sensitive about his own pessimism. He was to summon a Caster as his magical energy was low and he wished to avoid high-consumption combat Servants.

Anastasia
The Caster-class Servant who led the Oprichniki in their assault on Chaldea, hailing from the Lost Belts. Referred to as the Imperial Princess (皇女), appears to have a personality as cold as her powers. Capable of manipulating ice, her powers froze Chaldeas and rendered Chaldea uninhabitable, dropping temperatures to -100 degrees. She is accompanied by a shadowy beast with an evil eye, named, which is part of her Noble Phantasm, Viy, Viy, Viy.

She will be a key figure in the first Lost Belt, which also shares her name.

The black troopers that made up the bulk of the army which attacked Chaldea, the are the members of the, a secret police organization which operated in Russia during the reign of Tsar Ivan IV Vasilyevich (Ivan the Terrible), carrying out many acts of repression, persecution, torture and executions, particularly against the aristocratic class.

The Oprichniki who attacked Chaldea gave off Saint Graph reactions and stood up even when riddled with bullets. They massacred Goldolf's mercenaries and required Servants to combat. A large number of them along the coastline forced the survivors to submerge the Shadow Border into Imaginary Number Space in order to escape.

"Specimen: E"
At some point in 2016, an alien entity, designated "Specimen: E (検体：E)", was observed in New Mexico and brought to a top secret facility. At the time, the entity was unable survive without human aid, with a team of researchers working to keep it alive and hoping to establish communication with it. The biology of the entity was beyond human understanding, its shape resembling a tree root.

Invasion
Around the same time as the assault on Chaldea, several objects descended from the sky on an unnatural vertical trajectory and with their fall the Earth's surface was rendered white, turned into a 'blank slate'. Additionally, the planet was isolated, such that no light from any celestial bodies other than the sun could reach it.

Over the next three months, the Alien God responsible would rewrite the texture of the world and overlay the Lostbelts onto the foundation it had created. Each Lostbelt was sustained and rooted by a Tree of Fantasy grown from the seeds. From there on, the Crypters were to nurture and expand their assigned Lostbelts, eventually clashing with the others. The losing ones, with weaker foundations, would end up as nourishment for the winning ones, with stronger foundations, and the last survivor would claim the planet.

Various groups of people survived the initial blanking of the world and put up resistance afterwards to little avail, with the remnants of the United States falling a few days short of ninety after the beginning of the invasion. As they faced their end, one of them, David Bluebook, set out on a one-way journey to find the truth behind the mysterious invader and why humanity had been destroyed, seeking these answers so that they could rest in peace.

The Shadow Border in Imaginary Number Space
Following the escape from Antarctica, the Shadow Border remained submerged in Imaginary Number Space. After a week onboard, with supplies running low and the upcoming tides, the ship had to resurface. Given the condition of the world, the only connection back to reality they could make was with the Oprichniki, leading the ship to surface within the Russian Lostbelt. Due to the time differences from passing through Imaginary Number Space, a week had passed for the survivors of Chaldea while three months had passed on Earth. Having been damaged from the previous dive, the Shadow Border was unable to dive again until repairs could be made.

Lostbelts
With the release of this chapter, more information has been revealed concerning the exact nature of the Lostbelts.

Given their nature, the dates assigned to the Lostbelts in the PV are not the dates at which their events occur, as was the case with the Singularities. Instead, they are the points at which the Lostbelts diverged from the Greater History of Man.

Lostbelt No.1 - Permafrost Empire Anastasia
This Lostbelt diverged from the Greater History of Man in 1570 AD when an asteroid struck and plunged the world into an ice age. Most humans died, and while the Russians were used to the cold and prepared for such weather, 90% of their population perished and they were on the brink of extinction. Seeking help from mages, Ivan the Terrible managed to save the country by combining humans with magical beasts, creating the Yaga, with Ivan himself becoming the first. While they were able to survive, they lost vital elements of their humanity and as such, human history was deemed to have ended and the timeline became a Lostbelt, due to factors preventing it from being pruned.

This altered Russia has constant snow cover and is frequently in the grips of blizzards, with temperatures of minus 100 degrees Celsius. The country is surrounded by a vast storm with energy on par with nuclear weapons, forming a wall of weather which cannot be penetrated by any weapons or vehicles constructed at mankind's current level of technology. With the regions closer to the boundary being sparsely populated, few are aware of its existence. The Yaga had never seen a clear blue sky or starry night sky, with their equivalent of a blue sky being no blizzards.

The area covered within the Lostbelt corresponds to the western corner of Russia around the capital, extending past , and , with similar yet slightly different topography on its map. There are various settlements corresponding to those from the Russia of the Greater History of Man, though they are generally smaller than their counterparts, for obvious reasons. The settlements typically have 'Yaga' as a prefix, reflecting the changes to this Russia. At least one village was trampled and destroyed by an enraged Ivan prior to the Shadow Border's arrival, something which the Tsar regretted. The Yaga population is more concentrated within the more habitable heartland. The Lostbelt's Fantasy Tree, which was first seen by the local population three months prior to the Shadow Border's arrival, is located slightly to the north of Yaga Moskva (Moscow).

With the changes to Russia's environment, various magical beasts have emerged which roam the icy wilderness and are hunted by the Yaga for survival. Examples include the Krichat (a horned beast which is apparently easy for the Yaga to hunt and has a tendency to call others for help), the Razrušát (a large crab-like creature), and the DʹJávol Tróje (a multiple headed serpent, capable of destroying a village, which produces alcohol in its body). Several of the Yaga villages have created hunting grounds in locations ideal for hunting, gathering certain beasts and allowing them to reproduce, giving them a relatively safe and easy hunt later. These hunting grounds act as the villages' lifelines.

The primary law which the Yaga follow is that of 'predation' and survival of the fittest. Only the strongest are allowed to eat and live on, while the weak are considered unnecessary and abandoned, not worth preying on. Ivan the Terrible has ruled this Russia for over 450 years, with the Oprichniki enforcing his rule as he slept. During this time, various resistance armies have arisen to oppose him but all of the past rebellions have been crushed. When the Shadow Border arrived in the Lostbelt, the Tsar was being manipulated and kept asleep by Kadoc's faction as they prepared their own plans for the Lostbelt.

Lostbelts No.2 to 7
Though the Russian Lostbelt was the main focus of this chapter, a few details have been revealed concerning the other Lostbelts:
 * Lostbelt No.2's king is apparently quieter than Ivan, though they are apparently on the level of a Divine Spirit, according to Ophelia.
 * According to Hinako, Lostbelt No.3 is not suited for territorial expansion, though that statement may be due to her disposition. Its king has tendencies towards exploration and domination, leading her to worrying what he might do if she doesn't keep an eye on him.
 * Lostbelt No.4 has a 'Cube', which Daybit reckoned was a glaring weak point when asked for his opinion by Peperoncino. Pepe has also apparently found some good tea leaves somewhere in this Lostbelt.
 * Lostbelt No.5 has a certain city which Kirschtaria Wodime has conquered. The building in which he had a remote meeting with the other Crypters had pillars and arches with designs characteristic of.
 * Lostbelts No.6 and 7 have been noted to be rather primitive areas and ones which allow their Crypters to indulge in killing.

Crypter: Kadoc Zemlupus
The Crypter assigned to the Russian Lostbelt and Master of Anastasia, Kadoc Zemlupus is a magus from a relatively recent bloodline (at most 200 years old), average in terms of magecraft but was chosen to be part of Chaldea's A-Team due to possessing high Rayshift compatibility and aptitude as a Master (a trait obtained from birth and not hard work).

Due to his circumstances, Kadoc has an inferiority complex, one which increased after his selection for the A-Team, whose other members were all special in some way, and the events which led them to become Crypters. He also bears strong jealousy and resentment towards Fujimaru, the 'amateur' who completed the mission intended for the A-Team that he wasn't even able to attempt, and believed that if they could, even he would have been able to do it.

In the Russian Lostbelt, Kadoc assumed the position of court mage. As the Tsar was not letting the Fantasy Tree take root and was intending to reach out to the regions outside his Lostbelt despite this, Kadoc and Anastasia planned to overthrow him so the latter could obtain his authorities, have the tree spread its roots and rebuild Russia for the battle ahead. His faction manipulated the Tsar and kept him asleep, utilizing the Oprichniki produced during his slumber and fighting the rebels while secretly plotting his downfall, with Kadoc all too aware of what would happen to him if he failed and was caught. Due to his situation, he was suffering from stress and a lack of sleep, developing noticeable bags under his eyes, something which his fellow Crypters and allies commented upon. He wished to avoid other Servants in the Lostbelt dying as much as possible, but only because it would be better to have as many pawns as possible to achieve his ambition and overcome the obstacles in his way.

During the final stages of the Lostbelt's events, he helped to engineer a situation where Chaldea's team and the rebels would be forced to face the awakened Ivan together with his group. Following Ivan's defeat, Kadoc had Anastasia assume his authorities and command the tree spread its roots, while inciting the rebels to kill Fujimaru to prevent their world from being erased with the destruction of the tree. After Atalanta fell, he and Anastasia fought the Chaldea team, but lost the battle. Unwilling to accept defeat, he tried to change the outcome using the Sirius Right. Billy fired at him to prevent it but Anastasia shielded him from the bullet and was killed. He was then knocked unconscious by Billy and subsequently taken prisoner aboard the Shadow Border.

Anastasia Nikolaevna Romanova
Kadoc's contracted Servant and the Caster that led the Oprichniki in the assault on Chaldea, Anastasia Nikolaevna Romanova was the youngest daughter of, the last Tsar of the Russian Empire and the Romanova dynasty. During the, Anastasia and her family were held under house arrest before being by the Bolshevik secret police at. In her dying moments, Anastasia gained the qualifications for and entered into a contract with, a familiar of the Romanovas, who would torment her killers for the rest of their lives. This contract also enabled her to be summoned as a mage who embodies Russia.

Kadoc's Anastasia was somewhat distorted through her summoning to the Lostbelts, with the memories of her past and family blurred, and in her words, closer to being a Yaga than human despite her outward appearance. Originally naïve, innocent and somewhat mischievous, the events of the Russian Revolution gave Anastasia a cold and misanthropic disposition, one which was been exacerbated by the distortion. Though she hated the people and country who caused her death and the deaths of her beloved family, she also believed she had a responsibility as the heir to the Romanova dynasty to fulfill their duty and wish to unite and bring peace to Russia.

During the events of the Lostbelt, Anastasia helped to manipulate the Tsar in his somnolent state, posing as his who shared her name. Following Ivan's defeat, Anastasia became Empress and obtained his authorities, which were then used to have the Fantasy Tree properly take root, so that the Lostbelt could rebuilt and expanded. However, she and Kadoc were defeated in battle with Chaldea's team and when Billy attempted to shoot Kadoc as he tried to invoke the Sirius Right, Anastasia shielded him and took the bullet instead. Before dying, she told him to keep hold of his regrets and move forward, believing he would do what needed to be done.

King of the Lostbelt: Ivan Groznyi
As suggested by the presence of the Oprichniki, the Tsar of this Russia and the King of the Lostbelt is ', commonly known as Ivan Groznyi (usually translated into English as ')(called the Thunder Emperor (雷帝) in Japan due to an early mistranslation).

In the Lostbelt's timeline, the impact winter forced Ivan to seek the help of mages to find a way for his people to survive. Arriving at the solution of combining people with beasts, Ivan was the first to undergo this process, being fused with an ancient phantasmal mammoth and becoming the first of what would be known as the Yaga. Though the Magical Beast Hybridization Policy allowed his people to survive, it resulted in them losing vital parts of their humanity and the timeline subsequently being designated as a dead-end human history. Having gained a power and spiritual foundation on the level of a Divine Spirit-class Servant, Ivan would rule Russia for over 450 years.

At some point, he received a revelation from the Alien God concerning the nature of the Lostbelt and the Tree of Fantasy supporting it, as well as the Greater History of Man and the threat posed by Chaldea. Despite possessing authorities over the Fantasy Tree as the King of the Lostbelt and recognizing its role in preserving his world, Ivan didn't wish to use its power (born of the Alien God), preventing it from properly taking root and connecting to the leylines, while also intending to reach out to the regions beyond his Lostbelt. Because of this, Kadoc and Anastasia planned to overthrow him so the latter could obtain his authorities and have the tree spread its roots.

Ivan remained asleep for most of the Lostbelt's events, conflicted over his actions and path, pacified through Mozart's and later Salieri's music, and manipulated by Kotomine and Anastasia (pretending to be his advisor and his late wife  respectively), with his Noble Phantasm being used to produce Oprichniki for the purposes of Kadoc's faction. He was awakened during the final stages of these events, forcing the Chaldea team, rebels and Kadoc's faction to face him together. During the battle, Golem Keter Malkuth was used against his mammoth mount while Salieri's music was used to disrupt his strength, though the combined forces still struggled to defeat him. Eventually, when Ivan's shot at the castle was blocked by a returned Mash Kyrielight, Musashi used the brief opportunity to deal a grievous wound to the mammoth, followed by Golem Keter Malkuth ripping Ivan out of it before collapsing.

After being ripped from his mount and losing a brief clash with Anastasia over the throne, the heavily wounded Ivan faced Fujimaru's team near the tree, challenging them about destroying the tree when it would kill the Yaga as well. Despite declaring that he wouldn't lose to their 'weak' history, he was ultimately defeated. Remembering his beloved wife in his last moments, Ivan realized the Yaga had lost what they should have treasured most, their empathy, and acknowledged their defeat as he died.

Oprichniki
The army which attacked Chaldea (and the link which the Shadow Border used to return from Imaginary Number Space), the Oprichniki acted as the Tsar's enforcers within the Russian Lostbelt.

As various people suspected, the Oprichniki are part of Ivan the Terrible's Noble Phantasm, Chulnei Oprichnik, which activates when the Tsar falls asleep and automatically spawns soldiers to hunt down his enemies. Their individual strength is relatively low (except in the vicinity of the capital Moscow, where single units have power comparable to a low-rank Servant) but they are overwhelming in a group.

The Oprichniki were used by Kadoc's side, with the Tsar being manipulated to produce more of them, until the time came to wake and overthrow him. They disappeared when Ivan fully awakened.

Yaga
Faced with extinction in the impact winter, Ivan sought the help of mages to find a way for his people to survive. The solution they devised was to fuse humans with magical beasts in order to adapt them to the hostile environment. Ivan was the first to undergo this process and became the first of a new race.

Due to cannibalism resulting from shortages before the implementation of the Magical Beast Hybridization Policy, the new race elected to call themselves the Yaga, after the man-eating witch, so as to not forget the sins of their forebears. While the new race was able to survive, they had lost vital parts of their humanity, body and mind, in the process of fusing with beasts, resulting in their timeline being designated a dead-end human history for culling.

The Yaga were stronger and more robust than humans, with bodies which Koyanskaya described as close to that of an immortal. They were better suited to survive in the harsh cold but in exchange they burnt more calories, requiring ten times as many as a human in order to sustain themselves (they also had a higher alcohol tolerance).

Their typical mentality was that of survival of the fittest, with the strong being the ones to feed and live on, while the weak are considered unnecessary and discarded - much of the human capacity for empathy was lost as their minds became more bestial together with their bodies and as they faced the harsh environment.

Following the destruction of the tree, the Yaga were erased with the collapse of the Lostbelt.

Patxi
Patxi was different from most of the Yaga, in that he often thought about things which most of them deemed pointless to think about; why they had to be strong, why they couldn't be weak, why they were always hungry etc. For these reasons, he was ridiculed and an outcast in his home village, Yaga. His father was the leader of the local militia but was killed by the Oprichniki when he begged for food as a representative of the village. His mother had grown old and senile, to the point where she couldn't recognize him as her own son anymore, though he still continue to care and provide for her, despite the customs of the Yaga.

Patxi was the first Yaga that the survivors of Chaldea encountered in the Lostbelt, saving them from a magical beast, and he provided them with their first information concerning the changed Russia, being given hunting ground information in return. After being betrayed and accused by the villagers, and subsequently firing on the Oprichniki, Patxi was saved by Fujimaru's group and forced to flee his home with them, accompanying them on their journey and joining up with the rebel army.

When the rebels returned to Patxi's village and a battle ensued, he learnt that his mother had been stoned to death after he had fled, and ran away in grief. Not long afterwards, he was captured by the Oprichniki and had his spirit broken by Kotomine, who brought him to the sleeping Tsar, showing him Ivan's monstrous form and exposing him to the Tsar's aura, to make him lose hope, allowing them to extract the location of the rebels' storehouse from him. He reencountered Fujimaru in the labyrinth but was forgiven and learnt of the world which Fujimaru was from - a happier one where it wasn't only the strong who could live.

Despite being shaken by the revelations concerning the Lostbelt, Patxi sacrificed himself to protect Fujimaru from his fellow Yaga's bullets and urged them to continue to fight for their own world in his last moments, even at the expense of his own.

Minotauros
A more monstrous version of Asterios, going under the monstrous name associated with him, Minotauros. He was used by Kadoc's faction.

He was fought several times in the mountains and Yaga Moskva, before being slain as the battle with the Tsar was about to begin. Just before dying, he managed to glimpse Euryale and mentioned that he was a bit envious of the other side. The labyrinth created through his Noble Phantasm was used by Avicebron as material for Golem Keter Malkuth.

Counter Force Servants
Though the Human Order Foundation has been placed in jeopardy once more, it hasn't gone down without resistance. A number of Servants from the Greater History of Man have been summoned to the Lostbelts via the last embers of the Counter Force in order to fight against the invaders. Due to the interference caused by the Lostbelts, most of them are not able to recall any memories acquired after death, their memories from life may be hazy, and they are not bound to their purpose of eliminating the Lostbelts. Should the Lostbelts completely overtake the world, their current existence as engraved within the Human Order Foundation will be erased.

There are five Servants who were summoned to the Russian Lostbelt in this way; Atalante, Beowulf, Billy the Kid, Mozart and Antonio Salieri.

Atalanta Alter
Summoned as Berserker and Alter, with Agrius Metamorphosis active, Atalanta acted as the leader of the latest rebel army. Allowing the survivors of Chaldea and Patxi to join them, she and her comrades acted as allies for the majority of the Lostbelt's events. While she fought to give the Yaga freedom from the Tsar's rule, she was tormented by her knowledge of how the Lostbelt was bad for the world and how her existence, as engraved within the Human Order, would be erased once the Lostbelt claimed the planet, along with the people of the Greater History of Man, as well as knowledge that innocent Yaga would be erased if the Lostbelt was eliminated.

Following the battle against the Tsar, Atalanta reluctantly fought against Fujimaru, Mash and the others seeking to fell the Fantasy Tree, unable to abandon the Yaga who would be erased with the Lostbelt. Deeply conflicted, she subsequently hesitated in her duel with Billy the Kid and was fatally wounded, dying while crying and apologizing to both sides.

Antonio Salieri
The masked figure from the trailer, was a composer and conductor, who was friends with Wolfgang Amadeus Mozart in life. He also taught various musicians, including Mozart's protégé, his son , and. Though he wasn't the type of person who would normally be placed onto the Throne of Heroes as an anti-hero, his existence has been heavily distorted by baseless and malicious rumors that he killed Mozart, which persisted long after his death, mixed with the legend of the "gray messenger" tied to Mozart's last days and the commissioning of , resulting in his twisted form as an Avenger.

After being summoned to deal with the Lostbelt, Salieri was found by Kotomine and brought to Yaga Moskva, where he was compelled to assume Mozart's role in keeping Ivan asleep, as Mozart himself was about to disappear due to overexertion. During the time he was brainwashed, he went under the name Amadeus Alter. He fought against the survivors of Chaldea and the rebel army, but after the brainwashing placed on him was broken, he sided with them to continue his original role.

During the battle against the awakened Ivan, he used his music to weaken the Tsar. Following the destruction of the tree and the other Servants' departure, Salieri remained in the collapsing Lostbelt a little longer, playing "" on the piano for the Yaga.

Beowulf
Having been summoned to the Lostbelt, Beowulf spent a period of time wandering around aimlessly in the wilderness with Billy. Eventually they became bodyguards for a village of Yaga outlaws, soon becoming chiefs. When the rebel army and the survivors of Chaldea arrived, Beowulf and Billy fought them as a test of strength, before agreeing to cooperate with them against the Tsar's forces. Beowulf remained in command of the outlaws while Billy went with the rebel army, with the two groups moving separately towards Yaga Moskva.

Following the battle against the Tsar, he fought on the side of those wished to eliminate the Fantasy Tree and the Lostbelt, despite the pleas of the Yaga, who didn't wish to fight him, knowing that he was a good person.

Billy the Kid
Having been summoned to the Lostbelt, Beowulf spent a period of time wandering around aimlessly in the wilderness with Billy. Eventually they became bodyguards for a village of Yaga outlaws, soon becoming chiefs. When the rebel army and the survivors of Chaldea arrived, Beowulf and Billy fought them as a test of strength, before agreeing to cooperate with them against the Tsar's forces. Billy went with the rebel army while Beowulf remained with the outlaws, with the two groups moving separately towards Yaga Moskva. Along the way, he received an upgraded gun (from his 3rd Ascension), courtesy of da Vinci.

Following the battle against the Tsar, he fought on the side of those wished to eliminate the Fantasy Tree and the Lostbelt. He arrived after Patxi's sacrifice, disarming the Yaga and subsequently killing the conflicted Atalanta in a duel. He fired at Kadoc when he attempted to invoke the Sirius Right to rewrite the outcome of their battle, but Anastasia took the bullets instead. After her death, Billy knocked Kadoc out before joining the battle to fell the tree.

Wolfgang Amadeus Mozart
Despite being summoned to fight against the invasive Lostbelt, Mozart was instead convinced or compelled to assist in keeping Ivan asleep and pacified. He eventually disappeared due to overexertion but passed on his role to Salieri, who was compelled to carry it out.

Mash Kyrielight (Ortenaus)
Due to Galahad's departure, Mash's power and spiritual foundation was drastically reduced, not even half of what it had been before. Additionally, Mash's state of mind and the forcible activation of her abilities via Command Spell during the assault on Chaldea were not helping matters. In order to compensate for these issues, the group turned to the original Ortenaus plan, which was intended to counteract problems with the body that were expected to arise during the Demi-Servant experiment. This involved the use of technology to support and supplement Mash's weakened abilities.

Mash accompanied Fujimaru during the initial exploration of the Lostbelt. After returning to the Shadow Border and with others to protect Fujimaru, Mash assumed navigation duties. After equipping the Ortenaus and resolving herself, Mash returned to the battlefield in time to block a major attack by Ivan and create an opportunity for the others to defeat him. Following the destruction of the tree, an imitation grail was found in the remains and stored in Mash's shield, as the group needed all the resources they could find.

Avicebron
Avicebron was summoned by the survivors of Chaldea via the FATE system (despite not being registered among their Saint Graph records), powered by harnessed lightning for a single summon, in order to support them in their battles in the Lostbelt.

Avicebron greatly aided Fujimaru and the rebels throughout their struggle, though he briefly pretended to defect in order to scout out enemy territory, gather information and acquire certain materials for his Noble Phantasm.

Though he had some trouble recalling his post-death memories, he remembered and regretted sacrificing his master Roche during the events of Fate/Apocrypha. As such, when he activated Golem Keter Malkuth in order to face the awakened Ivan, he sacrificed himself in order to do so, leaving control of the golem to Fujimaru.

Miyamoto Musashi
Following the events of Shimousa, Musashi had been touring the world, travelling through both northern and southern countries. She visited Hawaii at one point and apparently managed to get along with the goddess despite her troublesome personality.

She was travelling with a certain eyepatched swordsman and Japanese government operative when she was dragged into the Lostbelt, having been chased to Russia from the Kuril Islands by assassins sent by the Russian branch of the Yagyu clan. For three months afterwards, she travelled across Russia, cutting down Oprichniki and Yaga alike (leading to rumor of a killer swordsman spreading like a horror story), occasionally helping some of the Yaga and identifying herself as "one from Chaldea".

Musashi eventually reunited with Fujimaru in the labyrinth and after helping him escape, joined the group for the battle at Yaga Moskva. The night before the group reached the capital, she talked with Mash and gave her advice. During the battle against Ivan, Musashi used the opening created by Mash's return to deal a grievous blow to Ivan's mammoth with her Noble Phantasm, but in the process reached the state of 'nothingness' once more and was subsequently rayshifted out of the Lostbelt.

Emissaries
It has been revealed that there are three Servants among the enemy forces who are "emissaries" of the Alien God, supporting but operating independently of the Crypters, and capable of moving between the Lostbelts. Kotomine (Rasputin) and Koyanskaya are two of them, with the third currently unspecified, though it is quite likely to be Ashiya Douman given his previous role.

Kotomine
During the events of this Lostbelt, Kotomine acted as an aide to Ivan the Terrible, under the identity of Cardinal, manipulating the Tsar for his side's purposes. It was also revealed that the Kotomine of the Grand Order timeline also died in 2004, with his body apparently burned without a trace.

Following Ivan's defeat, it was revealed that he was indeed the Pseudo-Servant Rasputin. However, after having helped Anastasia rise to power, Rasputin apparently decided his task was complete and moved on, leaving Kotomine in full control of his body.

Koyanskaya
During the initial stages of the events in the Russian Lostbelt, Koyanskaya was in command of Oprichniki and tormenting the Yaga, selling food to them at inflated prices and inciting them to turn on their neighbours to be able to purchase it. She encountered Fujimaru and Mash during one of these trips, but let them be.

Having completed her work, with the Russian Lostbelt having no hope for her to crush or fun for her to have, Koyanskaya left for another Lostbelt. After she departed, Kotomine mentioned how she had called her enemies rats yet her behavior was like that of a rat escaping from a sinking ship.

Kotomine also described her bullying of the weak and crushing of people's hopes as the form of her love for humanity.

The Alien God
The unnamed and unseen entity, responsible for turning the world into a blank slate, reviving the Crypters and causing the encroachment of the Lostbelts, referred to as the Alien God (異星の神). The entity's origins and motivations are largely unknown, though it is known to be trying to alter the world into one which can accept it. Its full reasons for using the Lostbelts to do so, other than using these lost histories to attack the Human Order and Greater History of Man, are also largely unknown at present.

The Alien God contacted the Crypters during their sleep, offering them, whom it referred to as chosen and abandoned ones, a choice between an eternal sleep or resurrection and glory, with an indifferent 'voice'. When the Crypters accepted in order to survive, it identified itself as a being from another planet who would descend upon the Earth. Stating that the Tree of Fantasy would initialize the planet and beget a new mythology, it tasked them with crushing the Greater History of Man and building up a world which would receive it. It granted each of them a Lostbelt as territory to nurture and expand, along with a Servant.

As well as recruiting the Crypters, the Alien God also gave revelations to the Kings of the Lostbelts such as Ivan, who was guided to destroy Chaldea and the Greater History of Man to ensure the survival of his Lostbelt.

Priestess of the Alien God
The unnamed (and so far silent) alien woman who appeared during the Prologue has been identified as the Priestess of the Alien God (異星の神の巫女).

She observed the meeting of the Crypters as well as certain events which occurred within the first Lostbelt. When the survivors of Chaldea had silenced and were attempting to fell the Lostbelt's tree, she froze and destroyed the tree with a touch. This time, unlike in the Prologue, she was seen by the protagonists, however she didn't appear to the Shadow Border's sensors (rather, there was a void where she should be).

Tree of Fantasy
The Cosmos in the Lostbelt equivalent of the Demon God Pillars, the Tree of Fantasy (空想樹) is what sustains a Lostbelt and anchors it onto the world.

The tree recognizes a single individual as the King of the Lostbelt and grants them certain authorities to reshape the Lostbelt's environment and expand the domain. In the case of the Russian Lostbelt, it was Ivan the Terrible, though he refused to use these powers given that the tree originated from a foreign god and didn't permit it to interfere with the ley lines, which is why Kadoc and Anastasia sought to depose him. At the time of Kadoc's encounter with Caenis, the Russian Lostbelt's tree was apparently the only one not to have spread its roots and started budding.

In the final battle of this chapter, the survivors of Chaldea and their allies attempted to fell the tree but once it was silenced, it was instead destroyed by the Priestess's touch. Afterwards, an imitation Grail was left behind which was collected and stored in Mash's shield.

Crypters

 * For Kadoc Zemlupus and Anastasia, see above.

While frozen in their Coffins after being critically injured by Lev's bomb, the Crypters were contacted by the Alien God, who gave them a choice; an eternal sleep or resurrection and glory. Wishing to survive, they all accepted the offer. They were each granted a Lostbelt as their territory, as well as a Servant. They were tasked with nurturing the Lostbelts and their Trees of Fantasy as well as crushing the Greater History of Man, in order to build up a world which would receive the Alien God. They were also informed of the one who had completed the task intended for them as Team A.

During the three months in which the Lostbelts were being fixed to the blank world, the Crypters were preparing for the competition which was meant to follow as their Lostbelts expanded and clashed (one which they believed would end in Kirschtaria Wodime's victory). They held regular remote meetings and discussions, maintaining a non-interference pact regarding the affairs of their Lostbelts outside of the clash to come. They were all changed somewhat by their experience, some more than others.

The Crypters possess a special type of Command Spell, referred to by Kadoc as the Sirius Right, one which can apparently be used to rewrite the Lostbelt, though its full capabilities have yet to be shown as Kadoc's invocation was interrupted.

Caenis
The Lancer who had previously appeared in the Cosmos in the Lostbelt opening and Class Introduction CMs, Caenis is one of three Servants contracted to Kirschtaria Wodime, apparently a Divine Spirit.

A of Ancient Greece, Caenis was raped by  and when granted a wish by him as compensation, wished to be turned into a man so she wouldn't suffer the same fate again. Poseidon granted her this wish and also made his skin impenetrable. Taking the name Caeneus, he led the life of a warrior, eventually meeting his end during the battle between the Lapiths and the, who being unable to pierce his skin, smothered him under a pile of tree trunks. In some versions of the tale, Caeneus reverted to a woman or became a bird after his death. In other versions, hubris and declarations of divinity played a role in his demise.

Caenis was instructed by her Master to observe Kadoc and Anastasia, and make sure that they didn't stray from the Crypters' mission, paying the two a visit at one point.
