The Sacred City

The Sacred City was located to the west of the Alps. It was managed by both the Holy Judgment Court and the Heresy Judgment Court. It was a place where laws were formed, the laws which every Mage in the world was bound to. As the location of the judgment courts, the Sacred City was guarded by The Seven Great Angels and magic formations to prevent evil/demon creatures from entering normally. The founder of the Sacred City was the creator god of magic and is referred to as Old Archangel, he is one of only two humans ever to have strength equivalent to a medium level emperor.

Referred to as the Seat of God, they were only responsible for supervising and purging threats. The City is currently guarded by Raguel, Raphael, and Uriel, (Michael as the head angel later joined once his identity was revealed)

Archangels
They were the seven strongest Mages in the Sacred City and so were named after the Seven Angels: Michael, Raguel, Raphael, Gabriel, Uriel, Sariel, Metatron, and Remiel. Asides those appointed as the guardians of the Sacred City, the identities of the other angels are unknown to the public due to the restrictions placed on Forbidden Curse Mages. Once their identities are exposed they would have to return to the Holy City. Their primary focus is on other Forbidden Mages and Emperor-level demon creatures. Seen as the apex of power they are still cautious of Emperor-level creatures and do not provoke one hastily.

The archangels rarely move or act as a group, when dealing with the Undead Emperor, Uriel stated that he would not help Michael regardless of the result as someone had to stand guard at the Sacred City in the event of a 3rd party attack.

Selection
The method is unknown but one is chosen to become an angel rather than cultivate their way there, so one does not necessarily have to reach forbidden level to become an angel. The decision to be an archangel also does not lie with the individual in question as Sharjah herself did not desire to become one yet could somehow not avoid it.

Sharjah believed the sacred city to be more complicated than most magic associations, stating that the archangels may not as be united as everyone is led to believe and it was impossible to tell if they were in fact righteous or evil in completing their duties.

Angelic Wings
Each Archangel has wings equivalent to their power level, These wings are external holy blessings placed on the Archangels to boost their powers while in the Sacred City, as a result the forbidden curse of an Archangel is multiple times stronger than a standard forbidden curse. The greater the number of wings the stronger the archangel. Michael and Uriel both have 16 wings each, Gabriel, Raphael and Remiel have 14 wings.

"Flaws" of their magic
During his fight with Archangel Gabriel, Su lu described the magic the Archangels used as rigid and a "carefully designed machinery". Their magic for the most part appeared as holy weapons for attack and a metallic city for defense and did not change forms like how typical high ranking mages use. He stated their magic was nowhere close to the power of a forbidden mage who had endured hardship to cultivate to that level due to them being born at the top of the world. The abilities of the seven Archangels from the Sacred City were from the official magic index. They were too proud to use any evil arts or forbidden magic.

Structure

 * Seven Great Angels - .Highest ranking officials in the Sacred City, they act as guardians and overseers and are the power houses of the City.
 * Judicators - Judicators are tasked with apprehending and restraining perpetrators until a judgment can be rendered. Judicators are typically at the level of Super-tier Mage or higher since it is their responsibility to apprehend dangerous criminals. They focus mainly on Super Mages and Ruler level threats.
 * Heresy Judgment Mages
 * Sacred City Mages

Magic Formations/Defence
The Sacred City can withstand a numerous number of forbidden spells due to the strong foundation it has, The Sacred City has a pact with the land of light which gives the archangels greater powers. Additionally it is said that the founder of the city had the strength rivaling that of a mid level emperor, during his time he constructed a number of Magical Formations to detect and restrict demon beasts.

Eye of the Golden Dragon
The Eye of the Golden Dragon was the symbol of the Sacred City, able to drive away every evil and demon creature. It sat atop the Sacred Residence and its power would cover the whole of the Sacred City.

Domain of Mirrored Space
One of the magic formations in the Sacred City, It was able to create an illusionary replica of the Sacred City with the exact same appearance as their surroundings, so that surroundings would not be destroyed and innocent people would not be involved when the Judicators and Holy Court Mages were carrying out their mission. This domain could replicate any portion of the city to its entirety.

Mutant Residents
Bola stated that some monster-mutants typically take up residence in the Sacred City to avoid persecution from different factions, organizations, people, and demon creatures in the wild. As such they have to hide in places supervised by the Holy Judgment Court and Heresy Judgment Court to guarantee their safety. Those who manage to survive here are capable of concealing their presence, or they have some old agreements with the Holy Judgment Court. Bola stated he could count as one of these people due to him being a part of the original construction of the Sacred City.
