Lore for Code Vein which will discuss vampiristic world and context of the situation in which the characters find themselves in.

 

Lore

Code Vein is set on a post-apocalyptic world after the event "The Great Collapse" happened. You play as a Revenant, a human that has been brought back to life to fight against the Lost.

Revenants

Revenants were created by implanting an engineered BOR parasite into the heart of a human corpse. BOR Parasites (Biological Organ Regenerative Parasite) attaches itself to the heart of a creature that has lost vital functions and sends its own blood into the host, allowing it to regulate and control all organs, including the brain.

BOR Parasites where discovered before the Great Collapse when creatures miraculously came back to life and eventually turned cannibal in a process called “Zombification”. Research into the phenomenon found that an unidentified life form had attached to the creature’s hearts and taken control of every cell in their host’s bodies. A procedure was developed, whereby the growth and contamination of the parasite is kept below a certain level. Patients will sleep for a varying length of time that cannot be predicted, but will awaken with their mind and volition intact: A Revenant. 

Revenants can only be killed by destroying the heart, where the BOR Parasite is located. Any other fatal wound merely causes the Revenant to disperse into particulate matter which stitches itself back together later. Destruction of the heart causes the Revenant to die in truth, their body decaying into packed ash. The initial awakening, and any dispersal of the Revenant, will cause some level of memory loss. This is usually unnoticed by the Revenant until someone causes them to notice the loss, or if the memory loss is large or particularly vital. Memories lost in this manner, at least ones vital to a Revenants personality, may form into a vestige, a blood-red crystal. 

Revenant bodies produce and manipulate a substance called Ichor. Ichor is used to fuel a Revenants strength and the Gifts granted by their Blood Code. All Revenant weapons are designed to channel and utilize Ichor to enhance their combat potential. Likewise for their Blood Veil-- a piece of clothing that acts as a Revenant's 'fangs'. Revenant's use their Blood Veil's to drain foes for Ichor. The exact nature of ichor is not examined, though it is stated that the substance was not known of until scientific inquiry into Revenants began. 

Each Revenant has a blood-type like factor in their blood personal to them alone, called their Blood Code. A Blood Code gives every Revenant unique Gifts, strengths and weaknesses. For all Revenants other than the Player Character, it is impossible to absorb and use anothers Blood Code, which instantly causes them to become Lost. The Player Character is an exception due to their Blood Code being damaged. This makes them 'Void-Type', and able to use any Blood Code that they have acquired by the absorbtion of a vestige or the consumption of another Revenant's Blood Code.

The Revenant condition has multiple dangerous side effects, however. The first is an unending and intensifying desire to consume human blood caused by their BOR Parasite stimulating their nervous system. Termed bloodthirst, neglecting this hunger will eventually cause the state of Frenzy and reduce the Revenant to a Lost. 

The Lost are Revenant whose BOR parasites have continued their infestation, spreading entirely through the body. As the BOR Parasite is no longer centralized to the Revenant's heart, the Lost are completely immune to death and will reform no matter what. The Parasite completely destroys the host personality, rendering them violent, mindless and cannabalistic. Lost are the primary threat in the city of Vein to its inhabitants. Additionally, Lost continually produce Miasma from their bodies which accumulates in the atmosphere. Miasma inhalation induces the Bloodthirst reaction in sane Revenants, rapidly reducing the time it would take for them to Frenzy.

Revenants can be roughly catagorised into four Generations, based on when their parasite was implanted. The 1st Generation revenants were the initial test subjects created to fight the Horrors, and potentially medical subjects from before the military applications of Revenants were considered. The 2nd Generation were produced under the Auspices of Project QUEEN, and were better equipped and supported through Queen-derived medications and technology. The 3rd Generation is the largest, a desperate production of Revenants to engage in Operation Queenslayer. Finally, the 4th Generation were produced from the black market sale of what few BOR Parasites remained in the wake of Operation Queenslayer. 

The Great Collapse

There is little information available as to the nature of the collapse. The Collapse consisted of the emergence of enormous thorns from the earth, known as the Thorns of Judgement, across every city in the world. It is estimated that half of the human population of the world died to this event alone. After this came the appearance of monsters, known only as Horrors when brought up, of an unspecified nature. The horrors were dangerous enough that it provoked the use of the BOR Parasite, originally intended to be utilized as a medical miracle, as a desperate and untested weapon. This resulted in the 1st generation Revenants. 

The 1st generation were able to secure the immediate surroundings of their research facilities from the monsters effectively, but the side effects of being a Revenant became clear quickly-- without a supply of human blood, several Revenants frenzied and became the first Lost, which were as dangerous as the monsters they were originally made to fight and, most worryingly, were completely immortal. Lost who even experienced their heart's destruction reformed eventually. Lost began producing Miasma which threatened yet more Revenants. Realizing the flaws of the program, Project QUEEN was intitiated under the encouragement of Silvia Gregorio. 

The Queen

Project QUEEN was an attempt to enhance the effectiveness of the Revanants and to reduce their bloodthirst, a response to the frenzying of many first generation Revanants into Lost. Little detail is available, but seems to have involves exposure of the Queen--Gregorio's apparent daughter Cruz-- to the blood of every organism the project could acquire. The project was initially a success-- the Queen did not experience bloodthirst, and was gifted with vast power which she used, in conjunction with the project, to create materials, equipment and drugs to aid in Revanant development and the Mistle, a plant-like organism that enhanced Revanant regeneration and soothed their thirst, and cleansed the air of Miasma.  The Revenants produced under the auspices of the Project are known as the 2nd Generation.

However, the parasite the Queen played host to as a result of this treatment caused her extreme pain. Eventually, the Queen lost her mind and Frenzied. The now wild Queen caused terrible destruction to an already ruined city, and produced vast quanities of Miasma that resulted in a catastrophic increase in Lost. Operation Queenslayer and a desperate increase in the number of Revenants to contain the Queen and the upsurge of Lost.

Operation Queenslayer

The operation itself was an act of desperation, as the Queen further decimated the surviving population. Mass numbers of Revenants were produced from just about any available corpses to serve as troops, and equipped with servicable weapons with which to fight the growing horde of Lost of the previous Generations. Gregorio Silvia intended to defeat the Queen and, in her place, clear a safe zone where humans may live and, in turn, support the population of Revenants protecting them with blood donation. 

The Operation was ultimately a success, of a sort. The Queen's heart was destroyed. However, Destroying the Queen's heart did not suppress her regenerative ability despite her technically not being Lost. The Queen was contained instead by dismemberment, each part of her body converted into a Relic that was in turn implanted into a 'Successor', a person who was biologically able to tolerate the Relic's presence. Each Successor was kept hidden within a Crypt-- an area enclosed by a barrier that protected the Relic and staved off frenzy, and that the Successor could not leave. Divided this way, the Queen was unable to regenerate, though her remains continually attempted to reunite.

The Gaol of the Mists

Not long after the Queen died, the city of Vein was surrounded by an impenetrable Red Mist. Those who attempted to pass through it were met with an unimaginable pain, and nothing from outside came in. Those in the so-called 'Gaol of the Mist' were prisoners there. 

The population within Vein was now predominantly Revenant due to the desperation of Operation Queenslayer, and the death of yet more humans at the hands of the Lost. Initially circumstances were not  terrible. Bloodsprings appeared, large white plants that produced Blood Beads-- Pellets containing a fluid remarkably similar to human blood. One blood bead could Revenants bloodthirst for around two months. Human blood was more pleasurable to consume than blood beads, and often caused Revenants to consume in preferentially, often to the detriment to the humans who it was taken from. There is no evidence consumption of human blood was addictive, however.

Secretly, the Bloodsprings were the creation of the Successor to the Heart, who altered preexisting Mistle to form them into conduits for the blood the Successor provided with the Queen's power.

However without the Queen, Mistle that fell ill could not be treated as it required a medicine derived from her blood. Miasma from the lost therefore began to continually accumulate. The available living space for Revenants dropped as the Mistles sickened and went dry, allowing the Miasma to thicken until even the filtration masks could not cope with it. These regions quickly became abandoned to the Lost. 

Worse, the supply of blood beads began to drop, slowly, as the Bloodsprings too began to fail. Chaos quickly engulfed the population until Silvia, with his Cerberus corps, established order with his Provisional Government. Most remaining humans were taken under their care, and provided with a safe and abuse free place to live (understandably for the Revenants however, this was in exchange for regular blood donations). The government levied groups of Blood Beads to redistribute them. While somewhat draconian, this limited the number of frenzies and restored some semblance of order. Humans were no longer hunted and Revenants ceased warring as much over the dwindling supply. The safe regions continued to shrink, however, falling to the ever increasing Lost population. The order the government imposed was temporary, at best. 

Few BOR Parasites remained within Vein, most of which ended up in the black market for exhorbant prices. From these emerged the final, 4th generation of Revenants. Very often, these Revenants are made from the corpses of the quite young, presumably created by their parents in desperation.

Another issue presented itself, out of the eye of the public. The Successors were a flawed solution. While able to contain their Relics, the power of the Queen within them caused them horrible pain, as the Relic corroded them from within. Successors regularly came close to frenzy, and if they all did, the Relics would be free to merge, and the Queen would be ressurected. A Watcher was appointed, who would watch over the Successors in their sealed Crypts. If they came close to frenzy, they would be slain, and their Relic transferred to a new host. 

Society

After the Great Collapse, “Cerberus”, a revenants operation unit was founded by Silva’s Provisional government. They are tasked with overseeing the lives of all revenants and collect a regular levy of blood beads, which they are also in charge of distributing. They effectively began the restoration of order, and ended the hunting of humans for blood and wars between revenants.

Not all Revanants are willing to partake of human blood, considering it a loss of their humanity. Human blood is, however, a more potent and alluring food source for Revenant senses, leading many to preferentially consume it when possible. There is no evidence of addictive properies to this preference. Fortunately for the human population, the provisional government protects the majority of them from abuse. The dwindling of Blood Beads, however, is an increasing threat.

Even after the Queen's death, the Miasma continued to rise, and with the city of Vein. Bloodsprings appeared which provided a suitable substitute to pure human blood, but the rising Miasma that continued even after the Queen's death and the eventual drying of the bloodsprings caused further unrest for the predominantly Revanant population of Vein, reducing safe living space and available supplies of blood.

      CV takes place in the US, the city center looks exactly like NYC look at the buildings and the taxis. most likely before God Eater 1. (the cast is diverse from many natiois the hint is their names) as hell just as Manhattan is too. Hell the dried up trenches look like a dead ringer for the bay of NYC. as ive travelled throughout that area. it seems CVs devs took inspiration from it.

        According to game lore. A BOR Parasite activates every cell (or type of cell) in the body. If that's accurate, then it stands to reason that it also activates sex cells. So if two revenants had sex, would their child be a human (because it doesn't have a Parasite) or a revenant (because of the changes that occur in the body when a parasite is implanted and the sex cells being blueprints of the body)?

          so is there a world outside the Gaol of the Mists? or did the horrors destroy it all? or do we just not know?

            I do believe Code Vein and God Eater the animation share the same universe. In one of the episodes involving a flashback with sakaki, johannes and Aisha, there is a specific scene which shows how it all begins. And that is, thorns appearing from the ground which the trio(or duo) then (some time later) mentioned it destroyed some large percentage of the population. That same scene shows how the first aragami, the ogretails, is born. The game clearly made no mention of thorns in any shape or form but that aragami suddenly appear one day. Some evidence with holes in building but nothing substantial. Contrary to that, the animation took a more gradual approach in aragami introduction, in that first a few weird mutated alien lifeforms were found in both sea and land, followed by the thorns and that the mass appearance of the aragamis. If it does infact share the same universe as god eater the animation, then perhaps code vein occurs either 1.Before the end of season 1 where Dayus Pita is still alive, as Dayus Pita is a one of a kind aragami. 2. Much later when more aragamis are able to take the form of Dayus Pita. Pita is now a rather common occurence.

              The way I see it, CV and GE take place in the same world, but in alternate continuities. CV takes place in a world where the Aragami appeared all at once due to the Great Collapse releasing them from underground, whereas in GE their appearance was gradual, with a few sightings here and there before they started showing up en masse and society collapsed. It seems BOR Parasites are unique to CV, either that or they're some type of Aragami which acts as a symbiote instead of devouring its host. Oracle Cells obviously were not discovered prior to the Great Collapse, but if the humans outside are able to fight the Horrors, they must have troops similar to God Eaters. Revenants are also able to fight them, since Mido says that the Horrors within the Gaol of the Mists were wiped out, so they are obviously resistant to the devouring ability of Oracle Cells. Because that is most definitely a Dyaus Pita making an appearance, and even though reusing assets is a thing, I very much doubt that Bamco would use one of God Eater's most recognisable Aragami out of sheer laziness. They knew full well what having Pita show up implies about the world of Vein and its relationship to the world of God Eater. There are too many inconsistencies with the sequence of events for me to think it's the same timeline, but an alternate continuity makes sense.

                Or... devs may simply not be as inventive? It's far from uncommon for a developer to reuse some assets in otherwise completely unrelated projects. Oracle cells and BOR parasites are fundamentally different organisms. As a concept they are the same, but every single detail is different. This is the first major "plot hole" here. Another one is lack of any mention of both in any game, in fact each franchise is quite exact on what each is and isn't. Then there are numerous differences that completely go against a single timeline or even setting: - If Code Vein is a prequel, there'd be a mention of an apocalyptic event in Got Eater. - If it's happening around the same time, there'd be Oracle Cell creatures in Code Vein and no, just because one creature has the same model and another looks similar isn't a proof, you may as well say Code Vein and Dark Souls take place in the same universe, because both games have Anor Londo and a set of enemies that are almost completely identical. - If it's a sequel, the Moon would've been green and humanity wouldn't be around, because there's no end to Oracle Cells and if Oracle Cells were somehow defeated, there'd be a heap of better weapons and technology for Revenants to deal with the Lost and whatever "Horrors" may be). For all intents and purposes "Horrors" may be the natural outcome of unchecked BOR parasites, whereas Revenants were "treated" with them in a controlled way resulting it vastly different outcomes. This also turns BOR parasites docile as long as they are fed, whereas God Arcs and God Eater themselves require multiple security measures in place to not go wild on the spot by simply existing. Another thing is the whole angle on the Mist thing. Officially it's "just there", slightly less officially it's there to protect humans on the outside, but in truth there are much stronger creatures running beyond it, meaning that humans on the other side may be actually doing worse than their counterparts inside the Gaol. The possibility of Revenants on the other side isn't ruled out though, as only the Queen was specifically created inside the city Code Vein takes place and Queen going frenzy actually made it less habitable for Revenants within the city.

                  God Eater does have "Thorns of Judgement" but they weren't told to us directly, even in God Eater, giant thorns were the outer border in each map. God Eater takes place in Japan, their called Aragami, however Vein maybe in the states, or more eastern, and let's be real here, if a guy saw a Aragami, we'd call them a "Horror" or a "Monster". if Vein does take place in god eater's world, it takes place in the past before God Eater 1, because in the last chapter the moon looks normal, it doesn't have a blue tint to it like in God Eater 2 or 3.

                    Weather or not CV is in the same world as GE is actually quite disputed. Disputed enough to spawn a 130+ post long discussion over on the Steam forums, and I'm sure it there are other places talking about it too. Personally, I think there's too much conflicting info for them to be in the same universe.

                    In Code Vein:
                    They are called Horrors
                    The Revenants were created to fight them
                    They appeared in the Great Collapse
                    and showed up with the Thorns of Judgement

                    In God Eater:
                    They are called Aragami
                    the God eaters were created to fight them
                    they appeared over time, with no special name for the event,
                    and the Thorns are no where to bee seen.

                    So I think they can't be in the same universe.

                    However, I do believe the Horrors and the Aragami are one and the same. After one of the endings, Mia comments on the Horrors' abilities. She says they are nearly immune to conventional weaponry and have regenerative abilities just like Revenants. Those traits match the Aragami's abilities. Not to mention that the Horror we see is clearly an Aragami.

                    So, in the end, I think that God Eater and Code Vein are two different worlds that had different responses to the sudden appearance of the same creatures. Like a diverging time line. Now, of course, this conjecture, and can easily be wrong.

                    On a side note, I saw someone point out that the humans outside of the mist would have to have some means of fighting the Horrors to have survived for so long. It's quite possible that they invented God Eaters of their own after the Revenants were lost. They would not the same God Eaters from the GE universe but rather people of the same form and function, if that makes sense.

                      It seems likely that it's in the exact same universe but it's practically impossible to tell when unless the dev's would confirm that...(everyone in vein is part of an isolated community that has zero knowledge of what is happening outside and vice versa, so it could even be at the same time as GE) I mean anything related to how much time has passed since the Collapse and the start of the game is super vague and probably made that way on purpose to avoid having to retcon too much. Or it could be a what if? Type situation.. same universe, different timeline. Or a nice easter egg for GE fans, although that is a lot of GE connections for it to be just an easter egg imo.

                        So does anyone know if Code Vein officially ties in with God Eater? Besides the Dyaus Pita making an appearance, there's a lot of overlapping stuff like the thorns of judgement showing up and the great collapse in general
