Arbitrator

Arbitrators or the Heavenly Arbitrators are group of mages with unique abilities, and each one possess their own attribute. All of them possess high class magic close to a Paladin, some are Paladin class mage, call this place is their home. Respectively, It consists of pillars that each member stand on, which has a mark of what is their Sacred Chest. There are only three free pillars for candidates. Unlike the Trinity Seven, they don't possess a Grimoire, nor a Thema or an Archive to connect to, as they can use their powers and abilities freely. However if they get serious they can use their respective Thema and Archive. According to Master Biblia if one Arbitrator is missing, they can be replaced by another one, though they must meet the requirements of the missing one.

History
The Arbitrators existed for a long time and years as they continue on new generations after they pass away, which they represent the old generations. During the old generations, Deus Trinity who were at that time unable to recognize and know love, so therefore it was always right for him to be devoted and be victorious. Deus Trinity rebelled against the Heavenly Arbitrators but he was defeated by them and thrown to the world of the humans. However Deus Trinity never gave up, wanting revenge on them, so in order to do so he challenged all the Arbitrators proposing which started the first great war in the human world. Some time after his resurrection he planned to challenge the Heavenly Arbitrators again whom took everything from him.

Many years have passed in the present times, Aries Cardia has been invited to become an Arbitrator giving her the position of her Sacred Chest "Time", which she accepted. As well as 8 others who were the current Arbitrators. It was then decided the one with the most authority and power will become the Arbitrator chief.

However a single problem arose when one Arbitrator never showed up whom was a prodigy with extreme intellect and became one at an early age, causing the Arbitrators to find another suitable candidate much to their dismay.

Later, the former missing Arbitrator, Arles Azazel, is revealed that she is making preparations to defeat the Goddess of Darkness.

Due to the Archive Melancholy being lost during the Great Magic War and vanished, and no one was able to connect to it yet, which concerned the Arbitrators. They needed someone who can connect to the Melancholy Archive. However it was dangerous since by researching it, it could revive the Goddess of Darkness.

Origin
The place the Arbitrators reside in is located in another world isolated from the real world. Which is called in the "Heavens", but it's not an island. Only the Arbitrators themselves know where it's located, as well only them themselves can enter and leave the place, however if they wish so they can bring others only if the situation is dire. An Arbitrator can retire if they wish so as well.

On the outside it has numerous buildings which each one has the same buildings and rooms for the Arbitrators. For example it has what the Arbitrator wants, such as taking breaks from missions. The tower to the headquarters can always be seen from all outside buildings. These buildings are very handy for them.

When an Arbitrator enters the headquarter door from bottom, their respective pillars automatically descends to them similar to how elevator functions.

Duty
Arbitrators duty is to maintain the balance of the world and eliminate threats that would disrupt the society using their wide information network with their abilities. They would even sacrifice one of their own to stop calamities from happening. However not all Arbitrators agree with each other, as Master Liber was in the way of both Maris and Faunaria, who were on the way to eliminate Arata. Though Master Liber only approached them out of curiosity, advising them to simply wait.

There is also an Arbitrator messenger, who's role to find them if they are out in the open taking a break for example. This messenger job is to find them and summon them to the Arbitrator Headquarters for urgent matters. Interestingly another Arbitrator can summon another Arbitrator if they are away to their Headquarters, and their designated pillar.

They can split in groups and perform tasks, such as the current one, to prevent the resurrections of the Goddess of Darkness. The Arbitrators have split into groups or sometimes solo.

Requirements
To become an Arbitrator, the mage must have incredible magic power inside them. They must achieve their own Sacred Chest as well as attribute via their own will or by extensive training.

Paladin class mages can become one easily, hence their massive magic power, yet becoming one isn't very easy but their process is much faster than normal mages. Some Paladins can become an Arbitrator without doing anything or training if accepted. Famous Paladin such as Master Bibila and Master Liber are qualified as an Arbitrator.

To achieve the rank of an Arbitrator is also completely rare, since they can use abilities according to their attribute willingly, without the use of any kind of Grimoires, however they do have a unique Thema's that an Arbitrator use from what they have "Sacred Chest" and they connect it to their corresponding "attribute" instead of Archive.

A Trinity Seven is capable of becoming an Arbitrator, though they must perfect their own abilities to the limit, as well the chance is very rare and nearly impossible, but they can be chosen as a substitute if their is a missing Arbitrator or if one wishes to retire, even so the chance is still rare if not unacceptable.

Symbols and Designs
On each Pillar there are symbol shape images which Arbitrator Sacred Chest or Ark. Some Arbitrators design their Pillars as they please, such as Harukage designed her Pillar by an umbrella, as well as a kettle on the side. With the umbrella rains down cherry blossoms. Murakumo's Pillar has many swords drilled into it, and Maris Pillar is filled with books. However some Arbitrators choose not to design them and have a normal Pillar.
