Magic

Magic is the primary source of power for Mages, and also their primary practice, there are three known schools which teach it that excel in the field, dubbed the Three Great Magical Academies.

Overview
Magic is the very power that people possess to stay in existence. Mages research and exercise this power that is deviated from the laws of the world. Which means, if one does not possess the power to stay in existence in that world or place, he or she may die, disappear, or lose control of themselves. It is not confined by logic or common sense, and is thought to be generated by emotions and desires. Body contact improves the sensitivity to magic.

Archives
In the Trinity Seven universe, magic is both an energy and an art form that magicians utilize to achieve a desired effect. However, all mages appear limited to studying one of seven respective Archives. Within each archive are many thema, which it appears mages can study more librally. Each of these archives are centered around one of the Seven Deadly Sins, they are:

Most magicians will choose an Archive and Thema that is opposite of what their personality is, as that appears to be the easiest for them to use since Magic is irrational by nature, in other words, they must think in a way contrary to themselves.
 * Luxuria (Lust)
 * Superbia (Pride)
 * Acedia (Sloth)
 * Ira (Wrath)
 * Avaritia (Greed)
 * Gula (Gluttony)
 * Invidia (Envy)

There are several magical armaments and tools that are available only to an individual who masters the respective Thema of said tool, for example the Ishgaroth member Rogue mastered three Thema and thus possessed three such tools.

contrary to the norm, even for Magic Kings, Arata can somehow use magic from other Archieves despite being a member of the "Superbia" Archieve.

Upon mastering 3 different Thema a magus earns the title of a "Trinity".

Luxuria, "Lust"
Luxuria's Archieve apparently possesses a large number of Thema centred around life and souls.
 * Vanitas: A Thema which symbolises darkness and nothingness, able to consume and return all of creation to nothing. The essence of Magic, as well as all seven archives, can be utterly erased by this power. Users:
 * Abyss Trinity(Main)
 * Abies: This Thema allows the use of a Magic known as Outer Alchemic, which allows the user, via rules of equivelant exchange, to create weapons for his/her own use. Users:
 * Lilith Asami(Main)
 * Arata Kusaga

Superbia, "Pride"
Superbia's Archieve is shown to possess magics which can reflect other magics, or magics which can dominate or erase them. This is because this Archieve represents "Pride" and inherently shows traits of domination.
 * Imperium, "Rule": Arata's main Archieve, this Archieve gives Arata the ability to reject and erase other magics, primarily called Anti-Magic. Users:
 * Arata Kusaga/Astral Trinity(Main)
 * Justitia, "Justice": This Archieve allows access to the magic called Gehenna Scope, which primarily focuses upon reflecting other magics, as well as scanning them to counter them. Users:
 * Mira Yamana(Main)

Acedia, "Sloth"
All three users of Acedia shown thus far have used powers which appear to focus upon magics that can manipulate space, such as teleportation and "Binding", it also seems it might have influence over time.
 * Stagna: This Archieve allows the use of the Magic "Chrono Calculation" which primarily seems to allow the user to teleport themselves, in other words calaculating positions in space-time, alternatively, they might be stopping time and moving about in frozen space. It also appears it can be used to absorb other people's magic, thus taking a "shortcut" towards improving their knowledge. Users:
 * Lieselotte Sherlock(Main)
 * Arata Kusaga
 * Ligare: This Archieve allows the use of "Secret Numbers Art" which primarily allows its user to bind other targets.
 * Selina Sherlock(Main)
 * Lieselotte Sherlock(While inside of Selina's body and camera, she displayed abilities akin to this Thema's properties, only is much more powerful than her sister. It's unknown if she has this Thema herself.)

Ira, "Wrath"
Thus far, users of this Archieve display abilities relating to errecting barriers, and/or smashing straight through other people's defences.

Avaritia, "Greed"
So far, this Archieve's magic appears to centre around bringing other's into one's own territory or world, which they can manipulate at will.

Gula, "Gluttony"
The Magics of this Archieve seem centred around one's emotions, and primarily focusing them into manifesting external entities or empowering one's physical body.

Invidia, "Envy"
The Magics of this Archieve appear to be centred around swift movement and/or trickery, techniques such as Ninjutsu themed magics belong in this Archieve.

Magus Mode
Magus Mode refers to the form a Mage assumes upon activating his/her Thema and powers, in this form, they are equipped with a type of magical uniform, which acts as a manifestation of their powers. Unfortunately, since Magus Mode is essentially a change of clothes into a magical uniform, dispelling the user's magic renders them utterly naked, this has earned Arata's Anti-Magic the nickname of "Stripping Magic".

Archieve Manifestation
By combining the Trinity with one's Magic King Element it is possible to manifest the true form of their Archieve and transform into a stage beyond "Magus Mode". Assuming this form makes the user very powerful, and gives them a likeness to the forms of the Genuine Magic Kings. An alternative to reach this level of power without assuming this form is to possess three weapons, available only to those who master an Archieve, and to bear a Magic King Element.
 * Ira Manifestation - "Satan": this is the manifested form of the Ira Archieve, which gives Hijiri a very demonic appearance. The transformation into this form appears to cause her great pain however it also grants her great power, power enough in fact to fight the entire Trinity Seven at once. Users:


 * Hijiri Kusaga
 * Luxuria Manifestation - "Aeshma": The manifested form of the Luxuria Archieve, assuming this form gives Lilith a rather immodest appearance. In this form, Abyss Trinity managed to use her power to rip open a gate to his world and regain his true power. Lilith is not a "Trinity" so it can be assumed she doesn't fulfil the qualifications to wield this power without external intervention.
 * Lilith Asami(Forced)

Trinity Form
Upon mastering four Archives and surpassing the "Trinity" Arata's Magus mode entered a state called the "Trinity Form", which is referred to by others as being a true magic king's appearance.

Spectres
As a Magician's Research of their "Thema" progresses they tend to lose control of their own magic and in turn, lose control of themselves. They turn into Spectres, beings that were once magicians that devoured by their own magic.
