Lostbelt backstory and setting notes

LB1,the Planet covered by Permafrost:
Confirmed in the 2018 year-end Mafia Kajita interview to be a collaboration scenario writen by the writers.
Lost Depth D,located in Russia
Deviation date happened in A.D 1570,caused by a meteorite impact which caused a second ice age to happen in the planet.
Everything outside of Russia is dead because of the extreme cold,while Russia barely managed to survive the ice age.
Ivan employed a magus to fuse the people of Russia with Phantasmal Beasts,creating a new species of humans that can survive in the cold but because of food shortages they had to resort to canniballism to survive,the new species of humanity took the name Yaga so as to not forget their sin while ironically abandoning another sin(Pity) in the process.
The non-Yaga creatures that survived are extremely vicious because of having to adapt to the extreme environment,ravaging anything that's alive to eat food.
By 2018,the Yagas were on the verge of extinction because their life cycle couldn't keep up with the extreme environment.
Ironically,the human civilization of Yaga Russia is more human than the civilization of the Eternal Qin Empire which rejected the Pan-Human History the least,which was stripped of their dignity as humans by QSH.

LB2,Northern Europe where god exists:
Lost Depth B+,located in Scandinavia.
Deviation date happened in B.C 1000,caused by Surtr rebelling against his destiny by devouring Fenrir to have enough power to kill everyone else,with Loki beoming the first casualty of Surtr-Fenrir.
Vanir and Aesir gods teamed up to beat him but by the end,only Skadi who Odin hid from Surtr's eyes to ensure her survival was alive.
Surtr was sealed by a dying Odin before he could kill everyone,the seal is the miniature sun seen in the Lostbelt.
Everything in the Norse texture aside from the small patch of land was rendered uninhabitable because Surtr's flames are still burning and Skadi is surpressing it to make sure it doesn't spread.
Most of the Valkyries died with only Ortlinde,Thrud and Hildr as the survivors.
Skadi created a management society to make sure the giants don't drive humans to extinction,by downsizing and ensuring the population of humans remained at 10.000 to make sure their heat signatures doesn't become high enough for the giants to detect them.
The dominant species of this Lostbelt is God,Giants and Humans in that order with Humans being on the bottom of the barrel and reduced to livestock without comparison among them.

LB3,Millennium empire ruled by the emperor who achieved the immortallity he desired.
Lost Depth E,located in China.
Scenario writer is Urobuchi,confirmed by the LB3 stream.
Deviation date happened in B.C 210,caused by Qin Shi Huangdi attaining immortallity by discovering the Fusang Tree.
Because of Qin attaining immortallity,the subsequent dynasties that succeeds Qin never came to be and the Qin dynasty became the Eternal Qin Empire.
Xiang Yu never served Xiang Liang but served Qin Shi Huangdi as intended,racking up body count exceeding his Pan-Human version's and getting continuously upgraded until he looks the way he does.
Han Xin took part in the conquest of India,Egypt,Roma and Aztec.
The rebellion caused by Qin Liangyu's husband still happened in this timeline only to get obliterated by QSH,he survived it and tried to do it again with a different village until he was killed.
LB Li Shuwen survived beyond the time of death of his Pan-Human version,in this timeline he is the captain of QSH's Imperial Guard at the age of 150 and reached the peak of martial arts.
Eternal Qin Empire eventually ruled the world with only small breakout of rebellions happening after he unified the world,after everything quieted down the only conflict remaining is wild animals occasionally attacking humans.
QSH used the Fusang Tree to create a imitation sage drug for his citizens to strengthen their immune system to get rid of disease completely,with it killing their consumers when they reach old age.
The only prosperous place in the Qin Empire is the Epang Palace where QSH,the imperial guards,the cryo-freezed heroes,and the artists QSH invited to create art for him resides,everything else is just hyper wheat farmlands Urobuchi copypasted from Psycho-Pass as far as the eye can see.
99% of humans in the Lostbelt are illiterate with the exclusion of the ones living in Epang palace.
This Lostbelt is disconnected from Alaya because the concept of prayer was lost and QSH hoarded chinese heroes in cryo-freeze.

LB4,Land of lotus repeating creation and destruction:
Lost Depth A,located in India.
The 11900 date associated with the Lostbelt tells that only 100 Divine Years(or 1000 days thanks to Arjuna Alter) are left until the end of Kali Yuga
A Square(Cube) exists here,judged to be the weak point of the Lostbelt by Daybit,it turns out the cube is the result of Ganesha and Lakshmibai's NPs and a Bootstrap Paradox made possible by Arjuna Alter's repeated resets messing up time and space,it's a weak point because the cube survived Arjuna Alter's resets and its existence was unknown to his Clairvoyance,and when it's identity gets discovered,Arjuna Alter's divinity gets more degraded because his concept as the perfect god falls apart.
Deviation date happened is unknown,but it was caused by Arjuna getting taken over by the Krishna (Black) personality thanks to the Kurukshetra War,who goes on to obtain Vishnu's divinity from Krishna and goes on to absorb that timeline's Hindu pantheon,becoming a god and replacing Kalki.
Originally,the Yuga Cycle of LB4 isn't as short as the current cycle but thanks To Ashiya Douman providing Arjuna with the energy of Cosmic Tree,he was able to shorten it to 10 days,causing the major-long term Yuga cycle to get accelerated thanks to his small scale Yuga cycles.
Lostbelt contracts and expands at set intervals thanks to Arjuna's resets
The Yuga cycle of creation and destruction of this Lostbelt is extremely shortened compared to the mythology,this is because of Arjuna Alter turning the definition of 1 Divine year=10 days(Satya=4,Treta=3,Dwapara=2,Kali=1) to accelerate the end of Kali Yuga to achieve his perfect world thanks to Limboman's persuasion.
With each reset,Arjuna Alter removes anything he doesn't deem perfect which ranges from inventions,anyone having minor injuries,anyone getting killed by Kalis,etc.
The presence of this Lostbelt is affecting Shiva and the Hindu pantheon's observation of Kama,causing the Mara aspect of Kama to be more prominent and the emergence of Beast 3/L.

LB5,Aquatic city where gods still exists:
Lost Depth A+,located in the Atlantic Ocean.
Deviation date happened in B.C 12000 coinciding with Sefar's invasion of Earth,the deviation is that the 12 Olympians and the Atlantean civillization survived Sefar's assault because Zeus forcibly connected with the other Olympians to kill Sefar.
The branches of Cosmic Tree Atlas has covered 80% of the planet's surface.
A hole in the center of the sea is actually the entrance to Olympus,Poseidon is guardian of the entrance and to get to Olympus you have to either get permission to enter or get past Poseidon and Artemis.
Artemis has the duty of shooting down anything that attempts to enter the hole using her Anti-Planet NP,after a team of Servants succeeded in entering Olympus Odysseus was granted the authority to give signals to Artemis to shoot down anything that presents a threat.
The citizens of Atlantis were originally Olympus citizens exiled from there because of they were supporters of the rebelling Olympians,they established several settlements in islands(actually the bodies of the defeated gods in the civil war) to live there,this was something not actually allowed by the Olympians but they didn't care enough to annihilate the exiles.
The discarded humans in Atlantis has a lifespan of 800 years,capable of defeating hydras with a group of only 4 people and long-distance communication thanks to the enhancement of the Theos Klinoromia.
Holmes refers the civillization of this Lostbelt as "the Stable World" which preceded the 4 great civilizations.
Has the highest prosperity level of the 7 Lostbelts and can be said to be more prosperous than the Pan-Human History.
The Polis(city-states) of Ancient Greece exists in the Olympus.
The sea of this Lostbelt is impossible to cross because it's filled by Phantasmal Beasts from the AoG and anyone would die before even getting to Olympus if they attempted to cross the sea,the difficulty of getting to Olympus has increased thanks to the Olympus defense fleet headed by LB Odysseus.
The Olympus 12 waged a war with each other after an argument on whether they should live together with humans or continue their rule,the result is that Hades,Apollo,Athena,Hestia,Hephaestus and Ares were defeated and Zeus,Hera,Poseidon,Artemis,Aphrodite and Demeter survived,by the end of LB5 part 1 among the 12 Olympians only Zeus,Hera,Aphrodite,Demeter and half of Hepheastus's brain are still alive in this Lostbelt.
Atlantis isn't actually the true LB5 but merely its underworld,the true LB5 exists in the Earth's atmosphere,Olympus.

LB5 Part 2,Interstellar City in the Mountain Range,Olympus.
The ruler

LB6,Land of Fairies at the end of the world.
Lost Depth EX,located in Britain.
Deviation date is A.D 0500,or ?? 2017,no one is certain at this point.
Lostbelt King is Morgan with her heir being Fairy Knight Tristan/Baobhan Sith
This Lostbelt contains Rhongomyniad that poses a threat to both the Alien God and the Crypters,causing Kirschtaria to request Beryl to cut down Cosmic Tree Seyfert to cause the collapse of the Lostbelt.
A curse exists in this Lostbelt that will cause the planet to collapse on itself once LB6 dies.
No land outside of Britain exists,as a result Fairies that originated from other lands ended up being condensed with Britain's fairies,causing them to be born in Britain when otherwise they weren't supposed to.
Occasionally,things from Pan-Human History somehow drifts into LB6 with the orc siblings and (implied) Fairy Knight Lancelot being some of the things that drifts here.
A 6 clan system exists,consisting of Fang,Wind,Earth,Wing,Mirror and King.
Northern Britain is ruled by the sole member of the King Clan,Knocknarea while everything else is ruled by Morgan.
The Dragon of Albion of LB6 is still alive somehow.
Merlin exists in this Lostbelt and is imprisoned in his tower by Morgan just like his Pan-Human version.
The Lostbelt contains mostly Phantasmal Beasts and very few humans.
Along with LB7,is considered "A unknown type of possible human history"
Unlike the other 6,it has a Wall of Light covering it which caused it to be unobservable to the Shadow Border's eye.
By the time Chaldea arrives at Scandinavia,the Britain Lostbelt is starting to disappear and Beryl is having his hands full just to maintain it.
The Prime Ones of this Lostbelt are Fairies with humans being the playthings and nourishment of the Fae,in that being near humans will cause a Fae's vitality to increase from happiness.
Lost Depth is ranked at EX because this timeline is something the planet isn't familliar with,as in,Human History is basically nonexistent in this timeline and a Fairy History that spanned 14000 years exists in this place so it's pretty much an isekai
The concept of birth is lost in this Lostbelt because Fairies do not have such concept in the first place and humans are "created" in a way similar to producing homunculi.
The Human Order of this Lostbelt is on the verge of breaking and the humans will likely go extinct in a matter of months.
The civilization of this Lostbelt is judged to be primitive,because Fairies are only concerned with imitating human civilization instead of learning from it so it's pretty much window dressing for an otherwise stagnant civilization.

LB7,Golden Forest where the beasts roam
Lost Depth A++,located in South America
Deviation date in B.C ????
Is considered "A unknown type of possible human history"
The weakest of the Lostbelts competing to replace the Pan-Human history in terms of the strength of the Human Order to the point it is unable to compete with other human histories.
As far as human anomalies goes,it's an anomaly among anomalies.
The human civilization of this Lostbelt is nearly extinct.
The civilization of this Lostbelt is judged to be primitive.
Xibalba is a physical location in this Lostbelt.
The Cosmic Tree of this Lostbelt has been cut down for unknown reasons.
The Ultimate One(Extreme Independent Species) of the Oort Cloud resides in LB7 and is active(well,writhing actually) because Gaia is dominant instead of Alaya in this timeline.
