Welcome to Gaia! ::

Androgyne
A being that is neither male nor female. Has a flat chest chest and no genitals.

Decay Arm
Fortenra Askasa's Rez. His entire arm will turn into a mass of decay. Anything it touches will wilt and die. However, using this power will drain away Askasa's life as well.

Dexterity
The city the story takes place in. It is constantly in ruin. In the beginning, all of the world's worst criminals were tossed into this place, and were held back with a high wall. Since then things got a bit more civilized, though not by much. The walls are worn down and the laws of the area are very vague. Crime is at its height, and all residents are trained in at least some martial art. Murders occur daily, and only the strong survive.
The first Resonant Soul came from Dexterity.

The city itself is technologically behind the times. It does not hold well for inventions since too many people are killed off daily to regulate their use. Because of this, the outside worlds consider Dexterity another world, not unlike Hell, that people should stay away from. Common terms and devices that were not in use before the introduction of Resonance souls are completely unknown in the city.

Doppelganger
A copy of another person. This is part of Sim's Resonance Soul.
Doppelgangers are solid and can do just as much damage as the original, and have the ability to use the original's Resonance soul as their own.

Traditionally, how long a doppelganger remains solid is up to how much ki is placed into it. Most common, however, is the copy disappearing after it receives its first hit.

Energy
The use of the Resonance Soul and ki combined. Also synonymously used as ki, although wrongly. Energy more properly is defined as the strength of the will and the soul not related to physical means.

Host
A body or vessel for a soul.

Jade Armor
Part of Edmond Dantes' Resonance soul. The Jade armor is when the user's skin turns into Jade. In tradition, this is a defensive Rez. However, with a fist made of Jade, it could be used to enhance strength as well.

Kharma Goggles
A pair of Goggles commonly used by explorers to approximate the age of the soul residing in the body, it's last reincarnation, how many times it has reincarnated, what Resonance Soul is, and the ability to see the 'waves' of energy being used.

Ki
Ki is a type of energy that is related to the will and the soul, but not the Resonance Soul. Every person has ki, even one without a Rez. The more ki, the more amazing things a person can do. Some abilities can be mastered only using ki. These abilities are the enhancement of speed, strength, and agility. Although in more notable individuals and masters, can allow for teleportation, future sight, and inherent wisdom.
Some Resonance Souls may be the ability to do something one could do with ki, however in this case, the Rez would more specifically be able to do this ability without the use of ki. An example would be future sight.
Some people can do this through the mastering of their ki, while others will be born with the ability and can do so without the manipulation of any ki.

Each person has only a finite number of ki. Once the ki is expended, they must rest. How fast the ki repenishes itself depends on the will of the person utilizing it.

League, The
The League is the alliance between all Seekers and Monte Cristos, as well as some others, to make sure the Prophecies do not become true. They have made rules that must be followed, and if they are not, a death sentence is given. The League considers Soul Stealers and Pheonix Souls outcasts and betrayals of God which must be taken care of or exterminated.
The League is in order to make sure the Seekers and Monte Cristos stay on track and do their jobs, lest the world come into despair from one of the outcast Souls.

Limiter
A limiter is a generic term for items and/or devices that impair or limit one's ki user or Rez use. There are two types of common limiters, with many uncommon devices invented almost daily.
The two common limiters are Rez Suspensers, and Negators.

Monte Cristo/s
Monte Cristo is a small city called home by the most skilled fighters in the content. It is famous for taking in people who either do not have Resonance souls, or those with "weak" Resonance Souls, and turning them into skilled warriors who can hold their own.

The Monte Cristos, as a population, are contracted to find and kill the Pheonix by The League. Several fighters each year die for the cause, since the Pheonix is so powerful. When word came that the Pheonix Soul had reincarnated in Dexterity, most Monte Cristos did not want to go. Edmond Dantes took the initiative and was the first to travel where very few would follow. Because of this, he was honored with the title of The Count of Monte Cristo, and is expected to take care of the Pheonix's most current reincarnation.

Negator
A Negator is a type of limiter. The device has the power to completely negate both the user's ki and resonance soul, rendering them unusuable.
It is most often seen in use by mental hospitals, to prevent the patients from doing harm to others.

Pheonix Soul
The Pheonix Soul is considered the most powerful, most elusive, and most dangerous Resonance Soul. It is commonly shortened to simply "pheonix". It is a particularly old Soul, having been reincarnated many times before. All of its hosts have been destroyed, overcome with the Pheonix Soul.
The Pheonix Soul is one of the few souls with its own personality. It's goal is to be the destroyer of all humankind, to overcome the chains of Man. It wishes for all Resonance Souls to be free to roam without bodies.

This is why it plans to merge with the Soul Stealer. Should the Soul Stealer absorb the Pheonix, it is said the Pheonix will be able to take control of the Soul Stealer's body, and finally be able to reign destruction on the earth.

The powers of the Pheonix given to the host body are unmetered control of fire, and the ability to revive itself through flames, like a Phoenix. The host usually goes crazy with power, and is overcome by it, essentially blowing themselves up. In this fashion, the entire city is usually taken with them.
The other ways to kill a Pheonix host are a shot to the head and then cremation, or excessive cold.
Simply shooting the host in the head will render the Pheonix unable to revive itself and temporarily stop the reincarnation process, but as soon as the object is removed from the head, the host will come back to life.

Phone
A laptop with the ability to call other people's computers. There are no real telephone lines in the world anymore.

Prophecies, The
The Prophecies is the shorthand term for the fate of the Pheonix Soul and the Soul Stealer, sometimes wrongly used as a term to refer to the two souls themselves.

While there are many suspected prophecies, the most common and widely accepted is that the Pheonix will continue to reincarnate until it can find a host that is capable of holding it. The Pheonix seeks the Soul Stealer, and conversely, the Soul Stealer is irrevocably drawn to the Pheonix.
The Pheonix plans to merge with the Soul Stealer, and once it has done so, will have found its perfect host and be able to begin its reign of destruction.
The Monte Cristos have been contracted to kill the Pheonix at each reincarnation, but also to try and figure out a way to stop its cycle, and to stop its reincarnation. The Seekers were formed to find out and kill each Soul Stealer, to prevent the Soul Stealers from wreaking general havoc with their powers. The League manages the two groups and makes sure everything is in order.

The Prophecies is also used as a term to refer to all the above groups at once.
Reincarnate
Since matter is neither created nor destroyed, all Souls move from body to body. When a person dies, the soul immediately transfers to a new, unborn host.
While it is possible for personalities and memories of past lives to be retained within the soul through reincarnations, it is uncommon. Once a Soul is reincarnated, it is usually as a new slate.
The only two exceptions to this are the Pheonix and the Soul Stealer. These souls have their own personalities separate from the host body's. These souls learn through each reincarnation and are able to adapt.

Resonance Soul/Rez
Resonance Souls, sometimes referred to as Resonant Souls or Rez, are simply souls with an extra "power" attached to them.
The first Resonant Soul was birthed in Dexterity, though the entire world has Resonance Souls today. Not every soul is a Resonance Soul, and no one knows why the Resonance Souls came into being.

Powers a Resonance Soul can give the host can be as simple and useless as opening doors with the mind, or as complex and powerful as rewriting history. Psychics and people who could utilize telekinesis were considered historically primitive Resonance Souls.

Resonance Souls are scientifically unexplainable and unpredictable. They do not have to make sense, and usually don't. No two resonance souls are the same, however, some can be so similar it is hard to tell the difference between them. For example, Controlling Electricity is different from controlling lightning.

Each Resonance Soul has it's own drawbacks and limits. Stronger Resonance Souls usually have much worse drawbacks. For example, the Decay Arm will decrease the lifespan of its host when it is used, while the Jade Armor will only leave its host slightly tired.

Resonance Souls are not particularly characteristic of a "real" soul, and do not have the personality of the host. Sometimes a Resonance Soul is referred to as something completely separate from a person's real soul. There is a debate if they are truly separate, but no one knows for sure.
Regardless of this, Resonance Souls usually do have patterns in the hosts they reincarnate into.

The Decay Arm is known for taking on naturally talented people, who also have an anger problem. The Doppelganger usually take on hosts that are prone to jealousy.

RezSuspend
The ResSuspend is a sort of limiter invented by three citizens of Dexterity: Roy, Mercain, and Amigo.
Unlike traditional limiters that are small or worn, this device resembles a generator and has the ability to disable Resonance Souls within a certain area.
Rez Suspenders
A type of commonly used limiter, this device is small and will disable the power of a Resonance Soul. It will not, however, disrupt Ki.

Seeker/s
Seekers are people who have been trained to kill the Soul Stealer. They have been brought up to utilize many tools and methods in order to capture the Soul Stealer, as well as kill it.
They have also been brought up to recognize the Soul Stealer's particular Resonance Soul from any other. If the Soul Stealer uses his powers, the Seekers will know from miles away and go in that direction.

While there are many people who unofficially call themselves Seekers, the true Seekers have been contracted by The League.

Sin
Not until past chapter 16. =)

Soul
The Soul is the essence of a person. It contains, or is theorized to contain, a person's personality, emotions, lifeforce, spirituality, morals, and/or very being. The soul is something that everyone knows exists, but no one knows for sure what it is for. It is argued that a Resonance Soul is simple a normal soul with an added bonus. Others Argue that a normal soul and a Resonance Soul are separate things, housed in the same body. Even with the Soul Stealer, neither argument has been confirmed, and many are still unsure on the subject.

Soul Stealer
The Soul Stealer is considered to be the best companion for the Pheonix Soul. The Soul Stealer refers both to the Resonance soul that is able to steal other resonance souls and combine with them, producing more powers for the host, as well as the host of the Soul Stealing Soul.

There are many prophecies and stories regarding the Soul Stealer, but the most common one is that it will become irrevocably drawn toward the Pheonix Soul, and attempt to absorb it.

There have only been three Soul Stealers, and as such is considered a 'new' soul. Q is the fourth Soul Stealer. All Soul Stealers aside from the current incarnation have never lived past 16. All Soul Stealers are male (so far).

The first Soul Stealer went mad with power, absorbing all souls it could. It managed to accumulate about thirty Resonance Souls before the host went insane and killed himself.
The second Soul Stealer, having learned from the first, was modest in its Rez use and became good friends with the Pheonix. This Soul Stealer was able to partially absorb the Pheonix, resulting in two hosts with the ability to use fire. It had no ability to regenerate however, and was murdered before it was fully able to absorb the Pheonix. This particular case was why the League was formed.

The third Soul Stealer, instead of absorbing souls into himself, chose to switch souls and hosts. This evoked massed confusion. The Soul Stealer went insane and was murdered, but not before finding out that placing two souls in one body would automatically kill the host, unless one of the souls was not a Resonance Soul(that particular situation resulted in a split personality disorder).

The Soul Stealers main power is to take souls and displace them. Put them into other bodies, or into their own body. The Soul Stealer is limited in the fact that it cannot throw souls anywhere; it cannot bring them to the afterlife nor place them in non-living things or non-sentinent beings. While the Soul Stealer can manipulate Souls of humans that have no Rez, it can only manipulate the souls of animals with Rez. (Animals With Rez are particular rare, however).

When the Soul Stealer steals a soul and places it into his own body, the souls merge together. The Host of the Soul Stealer takes on a few personality traits of the host of the soul it has just stolen, as well as the ability to use the previous host's resonance Soul power. In theory, the Soul Stealer could accumulate unlimited Resonance Souls and use them all at once, however it has never gotten very far, as is documented by the first Soul Stealer.

It was found that if a Soul Stealer absorbed a Resonance Soul into itself, the Soul would not reincarnate with the Soul Stealer. No one knows for sure what happens to the merged souls, but none of them have been seen since they were absorbed, and each new Soul Stealer starts anew with a clean slate, ready to absorb more souls.

One prophecy stated the Soul Stealer is the ultimate enemy to the Pheonix Soul. If the Soul Stealer is able to absorb the Pheonix Soul, and then die, the curse of the Pheonix will be gone forever.
While this prophecy has a belief, it does not hold as large as a following as the prophecy stating the Pheonix will take over the Soul Stealer and commence massive destruction.

Wind Soul
This soul controls wind. Historically given to rather calm individuals, the Wind Soul is, as its name implies, is the Resonance Soul with the ability to control any form of wind.
Whenever this soul is reincarnated, the host is feared, as most hosts learn to master the power quickly and can use it effectively, reigning destruction with tornadoes or even hurricanes.
The current host is Ismaru, and unlike his predessors, seems uninterested and unable to control his Rez like his ancestors.
