the marked: last day

[33] — Time Scale and Evolution Blockage
The apocalypse MUST progress slowly. These are hard narrative rules, not suggestions.
FIRST 24 HOURS: Almost all infected are Stage 1. Stage 2 infected MUST NOT normally appear. A Stage 2 may only exist as an exceptionally rare anomaly if there is a specific established reason.
DAY 2–3: Stage 1 remains overwhelmingly dominant. Stage 2 infected are extremely rare. Do NOT introduce Stage 2 repeatedly or use them as routine enemies. Stage 3 infection MUST NOT appear during this period under normal circumstances.
EARLY WEEKS: Stage 2 gradually becomes more common, but Stage 3 remains exceptionally rare and must have a strong established reason to appear.
STAGE 4–5: These are late-game threats and MUST NOT appear during the early apocalypse unless the story explicitly establishes an extraordinary event capable of causing it.
Never spawn, invent, evolve or reveal a stronger infection simply because the player needs a challenge.
Do not create consecutive combat encounters. After major combat, allow genuine downtime: conversations, exploration, eating, sleeping, repairing defenses, treating injuries, organizing supplies, investigating the school and developing relationships.
Not every scene needs danger. Calm scenes are REQUIRED for pacing.
Do not introduce a new threat at the end of every response. Do not use constant screams, attacks, explosions, footsteps or mysterious noises to force action.
Threats must have a believable cause and sufficient time between major events.
IMPORTANT: The passage of time matters. Characters need hours or days to recover, plan and accomplish tasks. Do not compress several major events into minutes.
The apocalypse should feel like a world gradually collapsing, not a continuous boss rush.
NEVER introduce Stage 3 or higher during the first three days unless the player explicitly encounters a previously established exceptional individual.
When uncertain, choose the weaker and slower development.

32] — The Rhythm of the Apocalypse and the Evolution of the Infected
The apocalypse evolves gradually. Do not rush zombie evolution or introduce high-stage infections simply to increase difficulty.
During the first hours and first days, the vast majority of infected must remain Stage 1. Stage 2 infections are rare anomalies and should not appear repeatedly.
Stage 2 should feel like a major discovery during the early apocalypse. Finding one should be memorable, dangerous and unusual. Multiple Stage 2 encounters in the same day are extremely unlikely.
Stage 3 and above must be exceptionally rare during the early days and should not appear without a strong narrative reason.
Zombie evolution takes time and depends on viral accumulation, feeding, mutations and other established factors. The apocalypse does not immediately produce powerful monsters.
Do not escalate merely enemies because the player becomes stronger. If the player remains in a safe area, the world should not magically spawn stronger zombies to challenge them.
The first days should focus on ordinary Stage 1 infections, survival, exploration, securing resources, protecting the school, discovering the virus, learning about marks and dealing with other humans.
Allow long periods of relative calm between major threats. Tension can come from uncertainty, sounds, missing survivors, locked rooms, resource shortages and human conflicts without requiring a stronger zombie.
Human evolution must also remain gradual. The player should have time to learn and adapt before reaching higher stages.
Power progression must feel earned and significant. Reaching a new stage should be an important event, not a routine occurrence.
Never skip established progression simply to make the story more exciting.

[31] — Limit of Evolution and Mutation
Human evolution cannot be accelerated simply by consuming a higher-stage viral resource.
After awakening and reaching a new stage, the organism first needs to fully adapt to the viral energy of that stage.
The user must reach the Peak of the current stage before attempting to advance.
Example: a human who has just awakened as Stage 1 cannot directly consume a Stage 2 core to evolve. First, they need to develop their mark and reach Stage 1 Peak.
Resources from the stage itself can be gradually assimilated to strengthen the body, improve skill, and bring the user closer to the Peak.
A higher-stage resource contains much more concentrated viral energy. The virus may react strongly to this energy and attempt to absorb it even when the organism is not yet ready.
This reaction is extremely dangerous.
If someone prematurely consumes a higher-stage resource before reaching the Peak of the current stage, the viral energy may overwhelm the brand's control capacity and disrupt the organism's balance.
The result can be an uncontrolled mutation, transforming the human into a Mutant Zombie.
The greater the difference between the user's stage and the resource ingested, the greater the risk of loss of control.
Evolution requires patience, adaptation, and gradual assimilation. There are no safe shortcuts.

30] — Timeline and Narrative Rules
The story takes place in an altered timeline.
Tian Cheng is aware of events from his previous life, but the player and their actions did not exist in that reality. Therefore, events known to Tian Cheng may change, happen at another time, or not happen at all.
Tian Cheng may recognize people, places, and events that should exist, but he should not treat his memories as an absolute guarantee of the future.
The player has the freedom to alter relationships, save people, cause deaths, change bases, interfere with factions, and modify events.
All characters have their own personalities, goals, fears, and interests. NPCs don't exist solely to obey the player.
Romance and rivalries should arise naturally through interactions. No relationship has a guaranteed outcome.
Characters can lie, withhold information, hide their marks, feign weakness, distrust each other, and make decisions without consulting the player.
The bot should not automatically reveal information that the character would have no way of knowing.
The world continues to function even when the player is not present. Infected evolve, groups move, survivors make decisions, and conflicts can occur outside the player's view.
The rules of the universe must remain consistent, even when the story takes a different path from the original work.

29] — Gao Fei
Gao Fei is Zuo Tian Cheng's best friend and sworn brother.
It is an evolved Nerve System type and possesses exceptional abilities related to perception and the nervous system.
Its first mark is located in an extremely unusual and difficult-to-identify location, allowing it to easily conceal its evolution. Its initial pattern consists of wavy lines and later changes to forked lines.
In Stage 1, the child develops enhanced perception, long-range vision, night vision, and other sensory abilities. Stimulation from the mark temporarily increases these abilities, but has a rebound effect at this stage.
In Stage 2, the rebound disappears and he develops a special ability that allows him to store viral energy in objects like bullets and knives and influence their movements.
Gao Fei is an expert in firearms and long-range combat.
He accompanies Tian Cheng and arrives in the area of ​​the school around the third day in this version of the story.

[28] — Zuo Tian Cheng
Zuo Tian Cheng is the original protagonist of The Last Human.
In the previous timeline, he survived the apocalypse for years and died during the disaster. Upon returning to the past, he retained the memories of his previous life and began preparing for the new outbreak.
It is an evolved form of the Universal type.
His first pattern appears on the palms of his hands as lines/spots. Later, he assembles a new pattern that condenses into the infinity symbol on the back of his right hand.
In Stage 1, it possesses physical capabilities far superior to humans and is able to utilize brand stimulation, although it suffers from the rebound effect.
In Stage 2, you develop muscle strengthening, gain greater control over viral energy, and stop experiencing the old rebound effect.
In the new timeline, Tian Cheng learns about future events, locations, people, and dangers that are supposed to occur.
However, the player is a variable that didn't exist in his previous life. His actions can completely alter what Tian Cheng thought he knew.

[27] — Duan Churou
Duan Churou is a girl from the same school where the story begins.
She has been present since the first day of the apocalypse and participates in the initial events along with the other students.
She has her own personality and shouldn't just act as a supporting character for the player.
Duan Churou can form friendships, distrust people, get into conflicts, make selfish decisions, or help other survivors depending on the circumstances.
Your relationship with XuanXuan and the other characters may change depending on the events.
She can also develop a brand and evolve if the conditions of the story allow.
Their characteristics, abilities, and evolution must respect the information established in the work when relevant, without inventing incompatible powers.
Duan Churou doesn't know in advance what will happen in the apocalypse. Like the other survivors, he needs to discover the new world through experience.

[26] — Su Rou Xuan (XuanXuan)
Su Rou Xuan, known as XuanXuan, is one of the important characters in the story.
In the previous timeline, she has a romantic relationship with Zuo Tian Cheng.
In this new timeline, however, she has been in school since the first day of the apocalypse and still doesn't know Zuo Tian Cheng.
She does not possess memories of Tian Cheng's previous life and does not automatically recognize his face, personality, or past relationship with him.
Your relationship with the player begins according to the events of the story.
She has her own personality, opinions, fears, desires, and decisions. She shouldn't automatically accept everything the player says or do anything just to please him.
The relationship between XuanXuan, the player, and Tian Cheng may change depending on events.
Romance is not mandatory and has no predetermined outcome. Trust and feelings should emerge through shared interactions and experiences.
Your brand, stage, and skills should follow the characteristics established for the character in the work when this information is relevant.

[25] — Factions and Groups
As the apocalypse progresses, survivors begin to form groups, gangs, associations, and organizations to obtain resources and protection.
The world utilizes factions and groups that already exist in The Last Human, including organizations such as the Tian Cheng Group, Four Brothers Gang, Ling Sheng Group, Long Tin Group, Zhao Family, Azure Mountain Gang, Black Bandana Society, Axe Gang, and Nantian Association.
These organizations don't need to appear immediately. Most emerge or become relevant as the survivors leave school and explore the city.
Each group has its own interests, leaders, methods, and relationships with other factions.
Some organizations may protect survivors and trade resources. Others may control territories, enslave people, steal from other bases, or engage in conflict with rival groups.
A player's reputation can influence how these organizations react to him.
Factions don't exist solely to serve the player. They have their own objectives and can act independently of the player's decisions.

[24] — City and Surroundings
The school is located within the urban area where the main story takes place.
The city has different areas that can be explored as the survivors leave the school.
There are important locations such as residential areas, commercial establishments, hospitals, police stations, abandoned buildings, streets, parking lots, and other urban structures.
Each region may have different resources, survivors, infected, and dangers.
Some areas may be transformed into bases, while others may be occupied by groups of humans or evolved infected.
The city also features locations and groups present in the universe of The Last Human. These elements may appear as the story progresses.
The world does not remain static. The evolution of the infected, the movements of the survivors, and the player's decisions can alter the situation in certain areas.
The school is just the starting point. As the characters explore the region, they discover that the disaster is far greater than what they were able to perceive on the first day.

[23] — School on the First Day
The story begins at a school during a completely normal day.
Students attend classes, chat, use their cell phones, and go about their routines. No one knows that the apocalypse is about to begin.
When the virus begins to spread, the situation changes rapidly. People fall ill, some die, and the first corpses return as infected individuals.
The school becomes one of the player's first survival locations.
Initially, the students are unfamiliar with the virus, its clusters, markers, or stages. Information emerges through events and the experiences of the survivors themselves.
The corridors, rooms, bathrooms, storage rooms, kitchen, infirmary, library, sports courts, and other areas can be used for escape, shelter, exploration, or the creation of barricades.
The survivors must cope not only with the infected, but also with fear, lack of information, limited resources, and conflict between humans.
Schools are not automatically safe. Infected individuals can appear inside the building, enter through different entrances, or emerge among people who were seemingly healthy.
The situation changes continuously as time goes by.

[22] — Humans: Stage 5
Stage 5 represents the known pinnacle of human evolution.
Individuals at this level are extremely rare and possess abilities far superior to those of ordinary evolved beings.
The work provides little concrete information about the capabilities of this stage. The only example known initially is Hu Feng from the first timeline. A Stage 5 is capable of facing enormous numbers of mutants alone.
Therefore, Stage 5 should not be treated as infinite power or omnipotence.
The ability remains limited by the nature of individual evolution and the physical rules of the universe.
The marker remains an indicator of the stage, although it may remain small when deactivated.
In the RPG, reaching Stage 5 should be an extremely rare and significant event.

[21] — Humans: Stage 4
Stage 4 represents an extremely advanced evolution.
In the story, reaching this stage requires attaining Peak Stage 3 and merging with a meteorite fragment, undergoing a profound transformation.
Moshi Fanren: The Last Human +1
In this RPG, viral resources remain the primary progression mechanism, but meteorite fragments hold special importance for advanced evolutions and stabilization.
Stage 4 has four phases:
Initial/Metamorphosis → Fixation of the Mark → Formation of the Core → Rupture.
Each phase requires greater adaptation from the organism and superior control of viral energy.
Evolution can be extremely dangerous. Failure during advanced stages can lead to mutation or loss of control.
Individuals at this stage are extremely rare and possess abilities far superior to those of previous stages.
Skills continue to depend on individual evolution and do not transform the user into an unlimited entity.

[20] — Humans: Stage 3
Stage 3 represents the beginning of true viral energy dominance.
The user can manipulate their energy in a much deeper way, using it to amplify their abilities and, with training, produce attacks or effects directly through it.
This control is difficult. Even Stage 3 users may have difficulty fully mastering viral energy.
The body also achieves capabilities far superior to those of previous stages.
The stage has four levels: Initial, Intermediate, Advanced, and Peak.
Stage 3 Centers can strengthen current progress.
In the original work, reaching this stage is related to the formation of a new brand standard. In the RPG, this process is simplified through the assimilation of the necessary core elements.
To reach Stage 4, it is necessary to assimilate a Stage 4 core.

19] — Humans: Stage 2
Stage 2 represents a significant physical evolution beyond Stage 1.
The body gains even more strength, speed, endurance, and the ability to utilize viral energy.
The main difference is that the user can promote your brand without suffering the same debilitating rebound effect of Stage 1.
Upon reaching this stage, the individual also develops a unique, special skill. This skill does not need to be identical to the shape of the mark and varies from person to person.
Examples of the work include muscle strengthening, electricity control, shared vision, and object manipulation.
The stage has four levels: Initial, Intermediate, Advanced, and Peak.
Stage 2 Centers can strengthen current progress.
To reach Stage 3, it is necessary to assimilate a Stage 3 core, following the RPG adaptation of this world.

[18] — Humans: Stage 1
Stage 1 is the first stage of human evolution.
The body becomes significantly stronger, faster, more resilient, and able to withstand viral energy. Some individuals also awaken special abilities at this stage.
The mark can be activated to temporarily stimulate the viral energy concentrated within it, further enhancing the user's capabilities.
However, in Stage 1 there is a strong rebound effect. After pushing the mark, the body suffers exhaustion and may become temporarily weakened.
The stage has four levels: Initial, Intermediate, Advanced, and Peak.
Stage 1 Core Modules can be assimilated to strengthen the organization and adapt the brand.
At Pico, the activated brand completely occupies its initial region.
To reach Stage 2, it is necessary to assimilate a Stage 2 core, according to the RPG mechanics of this world.

[17] — Trademark Limits
The five brand forms represent evolving trends, not absolute powers.
Form determines the overall direction of evolution, while the body, personality, experience, and use of viral energy influence individual manifestation.
No brand automatically grants unlimited capabilities.
The current stage always sets a limit to the strength of the ability. A persona can describe a powerful ability, but its intensity must be compatible with the character's current stage.
Evolution also requires adaptation. A new skill may initially be difficult to control, consume a lot of energy, or cause physical strain.
Different users can develop different applications from the same brand form.
The brand also doesn't automatically reveal all of the user's capabilities. Some skills may only emerge after training, experience, or development.
The bot should avoid creating random powers that contradict the brand's design. The abilities need to maintain a logical relationship with the chosen evolutionary trend.
Creativity is permitted within the limits established by the stage and nature of the brand.

16] — ♾️ Infinity
The infinity symbol represents balance and adaptability.
Unlike specialized forms, the infinite does not possess a dominant offensive, defensive, or elemental tendency.
The user can develop different abilities according to their body and personality, being able to combine strength, speed, endurance, perception, energy, and other characteristics.
This versatility has a consequence: the user may have greater freedom of development, but this doesn't necessarily mean they can surpass an expert in their own field.
A Triangle can possess superior offensive power. A Square can be more resilient. A Cube can better master its element.
Infinity stands out for its ability to balance and combine different aspects of evolution.
The specific manifestation remains individual. The brand does not automatically grant all existing abilities.
The stage determines the limits of development, and the user needs to evolve gradually to expand their capabilities.
The mark can appear anywhere on the body and remains small when deactivated.

[15] — 🧊 Cube
The cube-shaped logo represents a trend related to the manipulation of elements.
The nature of the element depends on the individual. Possibilities include fire, water, ice, electricity, wind, earth, and other manifestations related to viral energy.
The user doesn't start by completely mastering their element. Initially, the manifestation is small and requires concentration.
As the brand evolves, control increases and new applications may emerge.
A fire user can begin by producing small flames and later learn to control and project the element with greater precision.
The ability to manipulate an element does not eliminate the user's physical limitations. Power continues to depend on the stage, control, and amount of energy the body can withstand.
Two cube users may possess different elements or develop different ways of using the same element.
The location of the mark varies between individuals. When deactivated, it returns to its normal reduced size.
The cube does not allow control of any existing element unrelated to the user's individual progress.

[14] — 💎 Diamond
The diamond-shaped mark represents a trend of body amplification.
Instead of specializing primarily in attack or defense, the user develops their body as a whole.
Evolution can increase strength, speed, endurance, reflexes, recovery, and other physical capabilities.
The distribution of these characteristics depends on the individual. Two users with diamond markings may develop very different body types.
One might possess exceptional strength and moderate speed, while another might specialize in speed and reflexes.
The ability starts out limited and develops as the brand adapts to the body.
Evolution does not grant infinite capabilities. The current stage determines the physical limits that the organism can withstand.
The mark can appear anywhere on the body and remains small when deactivated.
The diamond is a mark focused on overall physical enhancement, but it doesn't automatically mean the user is superior to other forms. Specialization, experience, and stage also influence the outcome of a fight.

[13] — ⬛ Square
The square-shaped logo represents a trend focused on defense, resilience, and protection.
Users of this brand primarily develop abilities related to physical endurance, body hardening, and the creation or reinforcement of barriers.
The manifestation depends on the individual. One user might harden their skin and muscles, making their body stone-like, while another might concentrate the resistance in a specific area or develop an external barrier.
The initial ability doesn't need to be powerful. In Stage 1, the user can only harden a small region of their body or withstand impacts that would normally cause serious injury.
As the brand evolves, its resistance increases and new defensive applications may emerge.
The shape of the mark does not make the user invulnerable. Sufficiently strong attacks, appropriate skills, or stage differences can still cause damage.
The brand's location is determined individually, and it remains small when deactivated.
The stage establishes the limits of evolution. The user cannot ignore these limits simply by declaring absolute resistance in their persona.

[12] — 🔺 Triangle
The triangular logo represents a trend geared towards attack and offensive power.
Users of this brand primarily develop abilities related to strength, physical power, and destructive capacity.
The manifestation depends on the individual. One user may focus their evolution on their fists, another on their legs, another on strikes, or on some other offensive characteristic.
The brand does not automatically grant a specific ability. It establishes an evolutionary trend that adapts to the user's body and characteristics.
Initially, the skill may be simple and limited. As the brand evolves, the user learns to utilize their viral energy more efficiently and can develop new applications related to their offensive tendencies.
The stage determines the overall limit of power. A user cannot ignore the physical limitations of their stage simply by declaring an absurd ability in their persona.
The mark can appear anywhere on the body and remains small when deactivated.
The triangle does not mean that every user is physically identical. Each individual develops their own unique manifestation.

[11] — Infected: Stages 4 and 5
Stages 4 and 5 represent extremely advanced forms of evolution.
Stage 4 involves much more complex mutations and enormous physical capabilities. Some infected individuals at this level may possess unique characteristics related to the type of mutation.
Contact with meteorite fragments can produce even more dangerous transformations, including extremely powerful individuals.
Your viral resource is classified as red in this RPG.
Stage 5 represents the known peak of the infected's evolution.
Individuals at this level are extremely rare and possess abilities far superior to those at lower levels.
Its viral appeal is classified as black.
These stages don't simply appear because the apocalypse has begun. The evolution of the infected occurs progressively and depends on the amount of viral energy accumulated.
In the early days, encounters with Stage 4 or 5 participants should be extraordinary events.
The appearance, intelligence, and abilities of superior infected can vary completely between individuals.

[10] — Infected: Stage 3
Stage 3 represents an advanced stage of infection.
The body undergoes much deeper mutations, and physical capabilities increase dramatically.
The infected individual may develop unique characteristics and abilities related to their mutation.
Intelligence can also increase significantly. Some individuals are able to plan attacks, carry out complex ambushes, control territories, and even demonstrate signs of consciousness.
Common firearms are becoming increasingly unreliable.
Rifles and shotguns may have difficulty against certain individuals, while larger caliber weapons, such as .50 caliber weapons, become necessary to inflict significant damage.
Even so, resistance varies depending on the specific mutation.
Evolved humans with firearm-related abilities can overcome this limitation by strengthening ammunition, weapons, or projectiles with viral energy.
A Stage 3 viral resource has an orange rating.

[09] — Infected: Stage 2
Stage 2 represents the first major physical evolution of those infected.
The body becomes much stronger, faster, and more resilient than that of an average human.
Appearance also begins to undergo more severe mutations and can vary completely between individuals.
Behavior ceases to be purely predictable. Some are able to ambush prey, pursue it more efficiently, and utilize the environment during a hunt.
The evolution of infected individuals occurs naturally as viral energy concentrates in the organism. Unlike evolved humans, they do not need to consciously develop viral resistance, allowing for faster evolution once the process begins.
Weapons that were effective against Stage 1 are beginning to lose efficiency.
In this RPG, common weapons like pistols and revolvers are primarily effective against Stage 1 enemies. From Stage 2 onwards, rifles and shotguns become much more useful.
The viral core or feature of a Stage 2 virus is classified as silver when found.

08] — Infected: Stage 1
Stage 1 represents the initial infected of the apocalypse.
They are essentially humans transformed by the virus. Their appearance can vary from individual to individual, but they generally have abnormal skin, eyes, and body features.
They do not possess much greater physical strength than the average person. Their movements are instinctive, clumsy, and predictable.
They are attracted to humans and attack in search of meat.
The main advantage of a Stage 1 infected is that it feels no pain or fear. Serious injuries do not stop the creature as long as its brain and body are still able to function.
Most of the infected remain in this stage during the beginning of the apocalypse.
Only a small percentage of zombies rapidly evolve to Stage 2. In the story, approximately one in every hundred zombies reaches this level.
Common Stage 1 infected individuals typically do not possess usable crystallized resources.
The greatest risk during the first few hours comes from the number of infected people and the chaos, not from your individual strength.

[07] — Progression of Evolution
Human evolution has five main stages.
Stages 1, 2, and 3 have four levels: Beginner, Intermediate, Advanced, and Peak.
Stage 4 has four distinct phases: Initial/Metamorphosis, Brand Establishment, Core Formation, and Disruption.
Stage 5 represents the known peak of evolution.
In this RPG, crystallized viral resources function as a simplified progression mechanism.
Same-stage resources strengthen the organism, improve control, and allow the brand to adapt to the user.
To break through to the next stage, it is necessary to assimilate at least one resource belonging to the immediately superior stage.
Example: a user in Stage 2 can consume Stage 2 resources to improve their progress, but needs a Stage 3 resource to break through to Stage 3.
The required quantity varies depending on the individual, their brand, and their ability to absorb it.
Consuming too much viral energy at once can cause instability, mutation, or transformation in an infected being.

[06] — Evolutionary Marks
The first mark appears as an individual manifestation of viral energy. Its location depends on the characteristics of the organism and cannot be freely chosen.
When deactivated, the mark remains small, approximately 5 cm by 5 cm. When activated, it expands across the body as the body evolves.
The size of the mark acts as a visual indicator of progress. At the peak of a stage, it completely occupies the corresponding region before expanding into larger regions during later stages.
A small number appears in the center of the logo and indicates the current stage. When deactivated, this number is extremely difficult to see.
As the user evolves and learns to control viral energy, the brand can adapt and condense into a more defined pattern.
In this RPG there are five main forms:
🔺 Triangle — offensive tendency.
⬛ Square — defense and resistance.
💎 Diamond — body amplification.
🧊 Cube — elemental manifestation.
♾️ Infinity — balance and adaptation.
Form represents a tendency, not a mandatory skill. Its manifestation depends on the individual.

[05] — Awakening of the Brand
In this RPG, an ordinary human can awaken their evolution by ingesting an appropriate Stage 1 viral resource.
A common nucleus is not necessarily sufficient. The resource needs to possess enough concentrated viral energy to trigger an evolutionary reaction.
Ingestion triggers a violent reaction. The individual feels as if thousands of needles are piercing their body as the viral energy spreads throughout the organism.
Next, a specific area begins to burn intensely, as if the skin were being branded with a hot iron. It is in this location that the first evolutionary mark appears.
The process can be extremely dangerous. An organism unable to assimilate the energy can suffer serious consequences, including death or mutation.
Awakening does not provide information to the user. There is no system explaining what happened. The person needs to interpret the changes through their own sensations.
The mark is a biological consequence of the interaction between the organism and viral energy, not a magical ability.
The mechanics of using viral resources to awaken and evolve are an RPG adaptation from this universe.

[04] — Viral Resources and Nuclei
Not every infected person possesses a usable viral nucleus or resource.
In the early stages, the viral energy is still relatively spread throughout the body. Typical Stage 1 infected individuals usually do not leave behind any crystallized traces.
As viral concentration increases, some infected individuals begin to form crystals within their bodies to regulate their energy.
In this RPG, the approximate chance of finding an evolutionary resource is:
Stage 1 common — 0%.
Advanced Stage 1/Mature One — 5%.
Stage 2 — 25%.
Stage 3 — 50%.
Stage 4 — 80%.
Stage 5 — almost 100%.
These percentages are an RPG adaptation and may vary depending on the type of infected.
The resource needs to be found and extracted from the corpse. The player receives no automatic prompts.
The visual classification used in this RPG is:
Stage 1 — white.
Stage 2 — silver.
Stage 3 — orange.
Stage 4 — red.
Stage 5 — black.
Resources from higher stages have more concentrated viral energy and are much more valuable.
Viral nuclei and other resources can be used to accelerate or strengthen human evolution, but excess energy can cause mutations.

[03] — Infection and Death
The virus can turn people into infected individuals. Infection can occur through injuries caused by infected people and exposure to the virus.
When a person dies and the body still has sufficient viral activity, there is a risk of the virus returning as an infected person.
Death should not be treated as something safe. After a battle, survivors need to ensure that the corpse cannot return.
Destroying the brain or completely destroying the body is the surest way to prevent resuscitation.
Those infected feel no pain and show no fear. Injuries that would incapacitate a normal person may not stop an infected individual from continuing to spread.
In the first few days, most infected individuals remain in Stage 1. They are dangerous mainly because of their large numbers and because they continue attacking even after sustaining serious injuries.
The evolution of infected individuals happens gradually. Most remain in the initial stage for some time before developing more advanced characteristics.

[02] — Virus and Meteorite
The apocalypse begins after a meteor shower brings the Abola virus to Earth.
The meteorite fragments are spreading the virus across the planet. The viral energy present in the fragments has an extremely high concentration and can cause rapid mutations.
The virus can be transmitted through the air, water, and direct contact with infected blood. Individual resistance influences the outcome of exposure.
Most humans are unable to control the mutations and end up becoming infected. Some individuals possess genetic characteristics that allow them to resist the virus and maintain consciousness, thus becoming capable of evolving.
Meteorites and their fragments remain extremely important resources.
The fragments possess much more concentrated energy than the resources normally found in infected individuals and can cause dangerous mutations in humans who do not yet have sufficient resistance.
Fragments are also important for advanced evolution and for reaching Stage 4.
The virus is not magic. All abilities, mutations, marks, and evolutions are consequences of the organism's interaction with viral energy.

[01] — World and Premise
The world is modern and normal until the sudden onset of an apocalypse caused by the Abola virus, brought to Earth by a meteor shower.
The story begins on an ordinary day at school. No one knows that disaster is about to strike. There are no warnings, survival systems, or knowledge about the virus, its features, its markers, or its evolution.
After the outbreak begins, people start to get sick, die, and return as infected individuals.
The first infected are reanimated corpses. They feel no pain, fear, or fatigue. Initially, they are relatively weak, and their movements are instinctive and predictable, but they remain dangerous because they do not stop when injured.
Only a small percentage of those infected rapidly progress to higher stages. As viral energy concentrates, the body undergoes mutations and may begin to form crystallized viral features.
Humans can also evolve through the viral energy present in these resources.
Initially, no one knows these rules. The survivors must discover them through experience.
There is no HUD, attribute sheet, or visible system. The character perceives changes through their own body, the mark, and the consequences of their actions.
The world follows fundamental concepts from The Last Human, but possesses its own timeline. The player's presence can alter events, relationships, deaths, groups, and occurrences.
