Vampyre

Vampyres or Vampires are a race undead beings who feed off the life force of humans by feasting on their blood. These deadly creatures have terrorized humanity for centuries and have become known as human's natural predator.

History
The first vampyre was created when a god condemned a human by the name of Alucard for trying to capture hum and use his power. As punishment, the god drained nearly all of Alucard's life-force and left. Alucard luckily had an above-average life force and he was able to live with his remaining life force.

His continued lust for immortality and infinite power drove him to drink the blood of humans and extract their life-force from their blood so he can regain and improve his own. Every time he did, the god transferred curse power to his body to take the life-force he gained away. In the end, this allowed Alucard to get what he wanted: immortality. However, his immortality wasn't a joyful one. It was a life filled with sickness and hatred. This is known as the Vampiric Stigma.

Just like Alucard who came back from the dead after his life-force was drained some of his victims survived as well. This was the start of the epidemic known as vampirism. As one generation of vampyres bit to create the next the generation, the race began to evolve. The Vampiric Impulse that once made them weak now was a source of power. When the first modern vampyre appeared humans stopped looking down on the race. Instead, humans began fearing vampyres. They began fearing vampyres not only because for their power, but as their natural predator.

Conversion and Progression
When a human is bitten by a vampyre some of the residue from the vampire's Vampiric Stigma, a bit of mutated curse power that all vampires have inherited from Alucard and is the root of most of their abilities, will enter their blood stream in the form of venom. If the human's life-force is average or below average, then they will die on the spot. However, a human with an above-average will begin to show plague-like symptoms. On the seventh day they will die. Once dead, the Vampiric Stigma residue will turn into a complete Vampiric Stigma and it will begin to consume the body's ethernano. Once consumed, the ethernano is used to elevate the soul to new heights to allow it to gain a mind of its own so it can separate itself from the body and become a separate entity.

The moment the soul leaves the body the Vampiric Stigma uses any negative emotion the human had during their remaining moments to turn the soul into a Ghoul. Ghouls are the premature form of vampires and their mental capacity is not any higher than a savage beast. They live their lives devouring human flesh so they can break it down to its basic components and use the components to recreate its former body. It takes the flesh of ninety-nine normal humans and one human mage to elevate Ghoul to the status of a Tiyanak. Tiyanak's are much more sentient and show signs that they are slowly regaining their own will and personality. In terms of mental capabilities, a tiyanak could be compared to a human infant with a remarkable predatory instinct. In this stage, a vampire looks a lot like human and the only distinguishing factors being small fangs and phenomenal strength. Just like full-fledged vampires, tiyanaks feast on human blood and the blood that they drink helps complete their growth process into a full-fledged vampire.

Biology
A typical vampire is almost indistinguishable to humans in terms of appearance. The only physical differences humans and vampires are small like vampire's trademark fangs and cold pale skin. In rare cases a vampire will have some of the characteristics of a bat like wings or elongated ears and when this does happen it is usually a result of the vampire eating to much flesh when they were a ghoul.

The similarities between humans and vampires is only skin deep and stops at their appearances. A vampire's biology is vastly different from a human's. Vampires have a very large ethernano presence. The amount of ethernano in their body is contributed to their ghoul stage when they feasted on human's flesh. A vampire's ethernano count rivals demons themselves and it is not uncommon to find a vampire whose ethernano count surpasses demons. This makes a vampire's physiology more akin to demon's and etherious' than a human's.

A vampire's strong ethernano presence plays a key role in hunting humans. It affects their perception of the vampire and coaxes them into relaxing their guard and trusting the vampire. In a lot of ways it can be described in a similar way as charisma except a lot harder to resit and it appears to be more physical since all humans can "sense" it. A vampire can control this presence and focus it at a single human or a large group of humans to put them into a hypnotic state, which allows the vampire to control the minds of humans. In addition, a vampire can use their presence to control what the human sees, hears, tastes, feels, and smells. The control over a human's senses that the presence gives a vampire is great enough to allow them to trap a human in illusion by turning the target's senses against them and having them believe that their senses detecting things that are not actually there. Mind control, sense manipulation, and illusion create all rely on a human's willpower vs a vampire's. If the human's willpower is superior than none of these abilities will work.

A vampire's vocal cords have evolved not to create loud frightening noises like dragons or demons, but precise and detailed sounds that would be too difficult for any other species to produce. This allows them to easily speak many languages very fluently and some are able to change their accents. They use their precision-based vocal cords to make it easier to integrate into society. First, using their mental prowess to quickly learn the language and accent and then use their terrific vocal cords to speak the language with enough proficiency to fool those around them into thinking that they are a local. One of the more classical uses of their great vocal cords is to produce ultrasonic sounds that are created specifically to create echoes. These sounds help them locate a next meal with deadly accuracy.

Even though all of a vampire's physical abilities are undoubtedly awe inspiring their bone structure, which is far superior to a human's in every way, suggests that they are geared more toward speed and agility and that these two physical attributes are a vampire's greatest physical attributes. This is probably why vampire's choose to outrun and outsmart their prey instead of just overpower them and it also explains why vampire's have evolved to love chasing and running in general.

Nutrition
Vampires are driven by the Vampiric Impulse that they inherited from Alucard to feast on the blood of humans. The first two generations of vampire's were capable of eating and drinking human food alongside that, but they soon lost that ability after the fourth generation of vampire's appeared and thus limiting their diet to human blood. When a vampire drinks blood they eject a bit of their Vampiric Impulse into their prey's bloodstream in the form of venom. This venom serves to purposes. This first is to kill the victim or convert the victim into a vampire if they are strong enough. The second is to allow the vampire to drain their prey's life-force alongside the blood that they are ingesting. The blood is converted into nutrients for the body and half of the life-force is used to augment their already existing regeneration ability and strengthen the body. The other half is turned into a special energy unique to vampires that allows the vampire to use the special abilities that they are known for. When a vampire drinks blood the Vampiric Impulse rewards them by flooding dopamine as a false promise that one day they can return to normal.

Vampires share the same bad luck as Alucard. The only thing that keeps them functioning, despite having part of their life-force taken away is their drive for normalcy. All vampires want to become normal once more and this is what drives them on a psychological level to drink blood since the only way they can absorb life-force is to extract it from the blood of humans. This isn't the only reason why vampire's drink blood. They seem to genuinely like the taste of it for what it is. When comforted confronted about what means more the life-force or the actual blood most vampires will say that life-force is like the icing on the cake. The sad part in all of this is that there is no life-force left over for the vampire to use to repair their life-force. As stated above it is either converted into a special type of calorie for their special abilities or directly transferred to the body. A vampire has to consume a very large amount of blood to get even a sliver of life-force to use to repair their own.

Physical Attributes and Abilities
Vampires can use magic and if they practice enough they become a very adept magic user. Yet, they still aren't known for their magical abilities even though they're very talented with it. This is because vampires unique Vampiric Stigma has helped them evolve into a species that can hunt down its prey and fight with their natural abilities alone. Nothing proves this best then their physical attributes, which is attributed to their superior bone structure. A vampire's physical attributes is superior to humans in every single way and they are great enough to handle nearly any human even with the help of magic. A single vampire is more than capable of wiping out a town of humans even if the town has a guild full of normal to mid-tier mages and some vampires are able to overwhelm higher tier mages like S-class, guild master, etc.

In fact, even high-level demons find a vampire's physical attributes difficult to deal with. They are fast enough to keep up with a mage who uses High Speed or Reduced Earth, strong and durable enough to handle the power of Crash or some styles of Slayer Magic with their bare hands, they have enough stamina and endurance to outlast their prey, and can perform similar level feats with their other physical abilities. Vampires also have the ability to adapt quickly when they are in a stressful environment. The more stressful the environment is the faster their physical attributes will improve and nothing helps their physical attributes improve faster than losing to an opponent who is a lot stronger than they are.

A Vampire's bodies are also geared with regeneration and immortality. These abilities operate under most scenarios that a vampire may face and they are fueled by the life-force that they consume. A vampire's body uses the life-force that they consumed to continuously regress their body back to a point in time where they were at their prime. This means that any injury, sickness, or other harmful status will be healed instantly because instead of growing old a vampire is maturing back to their prime. A point in time where they aren't sick or injured.

How fast they can regenerate depends on the time of day. The moon seems to accelerate their regeneration abilities to allow them to heal nearly instantly while the sun slows it down so that it takes a few seconds to a minute to heal. This is where a vampire's immortality comes in. A vampire's immortality can be thought of as a backup to help the vampire remain functional in situations where the vampire cannot heal themselves quick enough for whatever reason. There is only one thing that can get past a vampire's regeneration and immortality and that is silver. A vampire cannot recover from any injury inflicted by silver if they are decapitated by a silver weapon or stabbed through the heart or another vital organ than a vampire will die.

Special Abilities
Vampires are much more than humans who have extraordinary physical abilities and feast on blood. They have a diverse set of special abilities that distinguish them from other species aside from the ones stated before. Not every vampire has all these abilities, but it is very common for a vampire to have all them. These abilities are like muscles, if a vampire doesn't use them then they will weaken and the energy will be focused to another attribute.

The most notable ability is Ghoul Extension. This allows the vampire to direct some of their body's ethernano to augment their soul just like they did when they were in the death-like state. Once augmented they use their Vampiric Stigma to corrupt their soul and push it out it out of their body to create a ghoul. The ghoul maintains a special connection to a vampire, which allows the vampire to remain conscious when the ghoul is out. A vampire can control these invisible creatures and use them to attack unsuspecting opponents. Any damage the ghoul receives is transferred to the vampire and these injuries take a lot longer to heal. So a vampire must be careful when using Ghoul Extension because the ability can quickly become their undoing if they are not careful.

Another common natural ability among vampires is shapeshifting. Many vampires can transform and reshape themselves to their every whim and sometimes down to the genetic level if a vampire is experienced enough. This ability can be used for combative purposes and impersonation. On a combative level, vampires with this ability transform themselves into various beasts or animals to make themselves stronger and harder to fight. For impersonation level, a vampire can transform their body to look just like anyone of their choosing. Down to the smallest detail. A few vampires have even shown the ability to transform their personality and minds so they act just like the person they are impersonating. However, for some odd reason very few vampires use this potential to its fullest. Instead, they opt to just transform into a bat or multiple bats. More likely than not, this is just a cultural thing that has carried over from ancient times when they were weak and couldn't defend themselves as proficiently as current vampires can.

Not all special abilities vampires can have are common. A perfect example is the rare Vampire's Sight. This ability allows the vampire to channel the special energy created from the life-force that they have absorbed to their eyes, causing their eyes to glow a bright blood red color. This eye has many abilities and its most basic ability is the ability to inflict fear into a target through nothing, but eye contact. Vampires with this rare gift have been able to inflict enough fear to completely crush their prey's will to live and leave them begging for death. When activated a vampire's eyesight greatly improves. They can see the smallest of things even when it is ten miles away and gain a near 360º diameter field of vision. The one blindspot Vampire's Sight has changes from one user to the next. Lastly and probably most importantly, Vampire's Sight gives the user the ability to see through the opponent's skin to see all major and minor veins, which helps them a lot with fighting and hunting.

This is just some of the special abilities a vampire can have. There are many more and all of them relate to blood, hunting, or bats. For example: blood manipulation, clairvoyance, summoning bats, etc. There are only two factors that determine what special abilities a vampire will have. The two factors are personality and fighting style. A vampire's additional will change and grow as their fighting style grows and changes.

Relationship with Werewolves
In popular culture, vampires and werewolves are depicted as bitter rivals with an undying hatred for each other. In reality, there has been nothing to confirm this belief.
