◆ The Present
The World’s Collapse and the Birth of the Revenants
—The Great Collapse
“The Great Collapse”—the name of the calamity that suddenly attacked the world. The Thorns of Judgment destroyed the greater part of most cities, and it is said that nearly half of mankind died.
—The Birth of the Revenants
Revenants are artificially created and immmortal soldiers made for the purpose of defeating the strange creatures referred to as “monsters” that appeared alongside the world’s destruction. They possess extremely high physical abilities compared to a regular human, and can vanish and revive any number of times as long as their heart is not destroyed.
—The BOR Parasite
“BOR” is an abbreviation for a parasite known as the “Biological Organ Regenerative” formula. It parasites onto the heart of a corpse that has lost its biological functions, and can control and operate all of its organs, including the brain, by pumping its own blood throughout the body.
By implanting an improved BOR Parasite into the heart of a dead human in order to keep the corrosion level at a certain condition, the Revenant—an immortal being that can maintain its natural will—was born.
The Characteristics of a Revenant
—Fogification
A “self-defense function” by way of the BOR Parasite in the heart of a Revenant that occurs when the functions of a Revenant’s body are stopped. The cells that make up the body disperse into the air, and the body revives through the reformation of the cells.
—Ashification
The total ashification of a Revenant host’s body caused by the bond collapse of the body cells when the BOR Parasite that parasited their heart is destroyed. In such a situation, the Revenant will never again be able to revive, and will meet their “death.”
—Memory Loss
In situations where a Revenant repeatedly dies and revives, and the parasite in their body is damaged, memory loss will occur. The Revenants themselves are unable to notice the fact that they are losing their memories.
—Losing One’s Sanity (Becoming a Lost)
When a Revenant’s thirst for blood exceeds its threshold, they will be reduced to a “Lost.” Once they lose their sanity and become a Lost, they will never again be able to go back to being a Revenant.
—Lost
The final stage of a Revenant, a human transformed by the BOR Parasite. When their thirst for blood exceed its threshold and they lose their sanity, they will become a Lost.
Since corrosion by the BOR Parasite accelerates and fuses at the host and cell level, the destruction of the BOR Parasite itself, otherwise ashification, is practically impossible.
A Lost is a true immortal monster that cannot be annihilated even if its heart is destroyed, and has absolutely no human reasoning remaining within it.
The Q.U.E.E.N. Project
A project with the goal of suppressing the “homogeneous blood thirst” defect of Revenants and creating the perfect soldier. By putting the blood of all living organisms into a BOR Parasite, success was achieved in the dispersion and suppression of the craving for homogenous blood, as well as the restraining of thirst symptoms, but the girl that was the subject of the experiment could not bear the constant and intense pain she endured and ran wild, which led to Operation Queenslayer.
—Q.U.E.E.N.’s Appearance
Q.U.E.E.N.’s arm is wrapped in bandages and she wears the hospital gown-like clothes she wore at the time of her rampage. Her body emits a miasma that accelerates a Revenant’s thirst for blood, making her difficult to approach. She has the powerful ability to manipulate countless thorns, and has slaughtered an innumerable number of Revenants. She also has the ability to control the Lost around her at she pleases.
Gregorio Silva (voiced by Akio Ootsuka)
A former soldier and Revenant. After the Great Collapse, from the Birth of the Revenants to The Q.U.E.E.N. Project, he has taken command in order to save mankind. Silva, who determined that the rampaging Q.U.E.E.N. would become a threat to mankind, started a fight to defeat Q.U.E.E.N., and even revived himself as a Revenant to take command.
Operation Queenslayer
In order to destroy the rampaging Q.U.E.E.N., a group of Revenants under Silva’s command fought a battle where the fate of mankind was at stake. Revenants produced from people that died as a result of the Great Collapse or Q.U.E.E.N.’s rampage were brought in as soldiers. The battle can also be said to be the main reason there are so many Revenants. After that, it was also a reason so many Lost were born.
—Many Revenants that were born under the command of Silva participated in battle.
—A violent battle against the Lost controlled by Q.U.E.E.N. The Revenants, who can revive any number of times as long as their heart is not destroyed, are flung around to the point of death.
The Government After Operation Queenslayer
After Operation Queenslayer, Silva launched the Provisional Government Office and ruled over the Revenants in order to manage the limited human blood and Blood Tears. There were quite a few Revenants who harbored oppossition under his severe tyrannical rule.
Provisional Government Office
The general term of the organization established by Silva after Operation Queenslayer. It collects and distributes Blood Tears to Revenants, as well as provides custodial care to humans using protective shelters.
—The “Blood Tax,” through which Blood Tears are offered to the Government Office, is one of the reasons weak Revenants are being enslaved.
—The remaining humans have also been robbed of their freedom and are faced with strict control. Human blood is valuable to Revenants.
“Cerberus”: The Public Order Preservation Force
A Revenant force that belongs to the Provisional Government Office led by Silva. It observes the actions of Revenants living in various areas, and collects and distributes Blood Tears at fixed intervals. It is formed of many who survived Operation Queenslayer, and its combat ability is extremely high.
Code Vein is due out for PlayStation 4, Xbox One, and PC in 2018.
