Reyvateil

Reyvateil are artificial life forms created with the most advanced technology in sound science. They are composed of organic matter, much like the proteins of the human body.

=Traits=


 * All are female, because the Y chromosome that males possesses supresses the Reyvateil powers, and thus, precludes them from drawing power from any of the song servers.
 * By singing songs, they can draw huge amounts of power directly from the tower (they can use song magic).
 * They can boost their magic by absorbing Grathnode Crystals into their bodies through a process called Install.
 * They can directly control the tower (only the ones with Hymn Codes)
 * Unless they have undergone through some kind of training, they don't have any physical qualities and are very weak, needing partners to protect them.
 * Almost all kinds can craft the songs from their own feelings and experiences.
 * Almost all kinds have a Cosmosphere, in which their partners dive to help them with the crafting of their songs (except Reyvateil Origin).

=Types of Reyvateil=

Origins
Reyvateil created from scratch. In alchemic terms, a homunculus. The tower administers and maintains their lives, and so, as long as the tower exists, they can live forever. The origins are mainly artificial beings, even if they also have many organics components in their bodies.

There are only 3 Origins in the world, since there are only three towers. They are considered the parents of all the β types and Third generations, who are directly related to one of these three origins. Each Origin´s Spiritual Frecuency is almost identical to the tower they are assigned to, and can control the tower as their own hands and feet. Since their minds are hosted in the Song Server of their Towers, they don't have Cosmospheres.

Known Origins
Shurelia (Eoria/Eolia), Frelia and Tyria/Tyllia

β Types & Pureblooded β types
The β Types are direct clones of the Origins, while the Pureblooded β types are clones of another β Type Reyvateils. Their life spans are rather long but extremely short compared to the life span of the Origins (about 150 years). They won't get old until they die. Origins and β types were made while the tower was still active, and therefore have a secure link with the tower. Each β type is assigned an ID from the tower so it can record all the settings in a Cosmosphere.

Known β Types
Misha Arsellec Lune and Mir/Jakuri

Third Generation
Children born from a Reyvateil mother and a human father. Most of the time, the Reyvateil capabilities are completely lost, but some children are born with Reyvateil powers. These are called Third Generation Reyvateils. Their life span is very short, usually less that 20 years, because of the power of the Tower surging through their bodies. Before people knew that this was because of their Reyvateil potential, it was feared to be a genetic disorder called the Tattolist Disease.

Third Generations do not have a Hymn Code, but they are still conected to the tower and are able to sing song magic, and can be as useful as any other Reyvateils. However, there are some exceptions, such as Reyvateils that have the Hymn Code of another Reyvateil because of a system error on the song servers, or Reyvateils that are using the β ER technique (the D Cellophane Grathnode Crystal).

Known Third Generations
All the Reyvateils in the World, except for the above mentioned

IPD
The IPD Reyvateils are a special kind of Third Generation Reyvateils, because they don't use the same song magic server as the other kinds. While the other types of Reyvateil depend on the Ar Tonelico server (which is also represented as the Sol Marta server in the second tower), the IPDs depend on the Infel Phira server (IPD means Infel Phira Dependency). Also, this kind of Reyvateils don't use the standard Hymmnos dialects, but use a completely different dialect created specially for them, the New Testament of Pastalie dialect. They are much more powerful than the standard Reyvateils, but also, they are prone to a disease called the IPD disease.

=Special Terms=

Hymn Code
It's a special identifier that every Reyvateil has in the Song Magic Servers. Only the Origins and β types possess this identifier. The Hymn Code is a requeriment for the Reyvateils to sing Extract type hymns, and this measure was made for the safety of the weaker Reyvateils.

Tattoolist Disease
It's a disease that only the Third Generation Reyvateils suffer, because of their inferior resistance to the power of the Tower. This disease first manifests when a tattoo (which actually is the Installer Port) appears in the body of a girl. After that, the girl begins to suffer from high fever, and if nothing is made, the power of the tower will continue surging until both the mind and the body of the girl collapse. Because of this, the Third Generation Reyvateils have an average life span of 15-20 years. This disease doesn't has cure, and the only remedy for it is the application of the Diquility and Tranquility medicines.

Reveris Disease
This sickness can effect any standard Reyvateil, and it's very similar to the IPD disease described below. This sickness doesn't have any known cure, and it's caused by a virus that was spread in the Ar Tonelico server in recent times. It's only described and shown in the Ar Tonelico: Arpeggio side story manga. Reveris means "nightmare" in Hymmnos.

IPD Disease
This is a disease than only affects the IPD Reyvateils, and its cause is the destruction of a part of Infel Phira during the war, and also, it's caused by a virus that only affects them that was spreaded sometime after that. This disease manifests in two forms: Positive and Negative. The positive form is an attack of madness where the Reyvateil loses conciousness of herself and begins to attack anything on sight, which could even end in her own death. The negative form manifests as a sudden outburst of fever and loss of conciousness, and whenever the negative form manifests, the disease it's contagied to any Reyvateils that are in 50 meters around of the infected one.

Because of this, the IPD Reyvateils don't have Mind Guardians, and also, the boundaries that separate one Cosmosphere from other are non-existant. This disease has only a cure: Dive Therapy, but because of its banning in Pastalia, the only solution found was to isolate the IPDs from the rest of society.
