Slane Theocracy (スレイン法国) is a human nation of the New World and one of the three nations that neighbors Nazarick. One of the strongest countries in the region; it is a highly religious, orthodox state, promoting human supremacy.


Overlord II EP01 090

The Theocracy's geographical location

Being one of the oldest established human nations, the Slane Theocracy has a history of six hundred years based on fierce adherence to their country's religion. The doctrine of the Slane Theocracy revolves around the Six Great Gods, who appeared six hundred years ago. As a result, the country is divided into six different religious sects, each with its own specialized intelligence agency focusing on one expertise they're skillfully good at. Each sect is devoted to one of the Six Great Gods by the Scripture group's color.

Despite being split into different factions, the groups will still co-operate when necessary during times of crisis. They all acknowledge the threat of demons and other races in the world. Additionally, the Slane Theocracy's civilization is said to be more advanced in technology than any of the neighboring countries that surround it. The Slane Theocracy also has an institutionalized divine magic training system that is comparable with the Baharuth Empire in terms of arcane magic, one in which they possess a magic school that focuses on training faith-based magic casters. The overall literacy rate for citizens living in the Theocracy is fairly high.[1]


Overlord III EP06 104

The Theocracy's discrimination against non-humans

Although the Theocracy promotes the discrimination of non-humans and the supremacy of humanity, it only serves to be a tactic from the higher-ups in order to unify all humans with a common goal and increase their national power. Unlike the common folk, the high officials aren't blinded by xenophobic beliefs and prioritize the survival of humanity. In order to protect humans from the threat of other races, they have decided to bind people together with faith in the Six Great Gods. It is to this point where they have tried to keep all God-Kin within their country's borders, even going as far as to detain their wives/potential mothers.

At the same time, the Cardinals recognize the fact that their nation's philosophy has a flaw to it. They fear that their nation's ideology might lead them in a dangerous direction if the Theocracy ever ends up being bordered next to a powerful non-human nation like the Argland Council State. The Cardinals believe that it can play a major factor in radicalizing the citizens to come together and form a militant movement against that nation. Since this event is the worst-case scenario, the common folk will possibly shout for war with the Council State in order to destroy the enemies of mankind.

The citizens of the Slane Theocracy often view people with nonhuman ancestry living in their country as second-class citizens.[2]

Theocracy - Elf War

Despite the Theocracy's prejudice towards non-humans, the nation once had a friendly relationship with the neighboring Elf Country. However, this relationship came to an end over a century ago when the Elf King abducted and impregnated the ace of the Theocracy's Black Scripture. Fortunately, the Theocracy rescued her and the child that was forced upon her grew up to become the Theocracy's strongest God-kin.

Afterwards, at the urging of the child, a war of retribution was waged against the Elves. However, despite their superior military strength, the Theocracy's progress is slow since the Elf Country is mostly hard-to-traverse woodland and they do not want to waste their full forces on the war effort, resulting in the war still going on by the time the Re-Estize Kingdom fell. Elves have also become favored products in the Theocracy's slave trade.


In order to achieve their goal of allowing humanity to survive in the face of demi-human threats, the Theocracy has been secretly manipulating the affairs of other human nations for what they believe is the greater good.

One of their actions was to shepherd the Re-Estize Kingdom, a human nation completely protected from demi-human nations by its neighbors and natural barriers. They believed this would allow the Kingdom to safely raise powerful individuals who could save mankind. However, its life of peace instead caused many nobles to become arrogant and delusional, resulting in the Kingdom becoming nothing but a cesspool of corruption.

Deeming the Kingdom to be a failure, the Theocracy shifted its focus to the Baharuth Empire. Since the Theocracy couldn't directly take control of the Kingdom lest they share a border with the Argland Council State, which would inevitably lead to a war, they instead planned on letting the Empire conquer the Kingdom.

The Theocracy's failed assassination attempt on Gazef

The Slane Theocracy decided to take action to further their agenda over the Re-Estize Kingdom by assassinating Gazef Stronoff, the kingdom's strongest warrior and the main obstacle for Re-Estize's conquest by the Baharuth Empire. To accomplish this task, the Sunlight Scripture was dispatched to lure Stronoff while aided by the foolish nobles of the Nobility Faction, who were easily manipulated to think that this was their own plan.[3] During the operation, the Theocracy had the Sunlight Scripture under observation. However, for some reason, they lost the whereabouts of the entire force.[4]

In addition, the Theocracy had received a prophecy of the Catastrophe Dragon Lord's resurrection. In response, the Black Scripture was deployed to slay it. The Theocracy even lent them their nation's secret weapon, the World Item of the Six Great Gods; the Downfall of Castle and Country.

Clementine steals the Crown of Wisdom and goes rogue

A disaster struck the Theocracy when one of the Black Scripture members, Clementine, stole one of the Six Gods' treasures, the Crown of Wisdom, and went rogue. In response, the Windflower Scripture was sent out in pursuit of her to retrieve the item and execute the traitor.[5]

The Black Scripture is defeated by a powerful vampire

Another disaster struck the Theocracy when the Black Scripture encountered a powerful vampire. While the Black Scripture managed to partially brainwash the creature, this only caused it to indiscriminately attack anyone who approached it, forcing the Scripture to retreat.[6]

After the Black Scripture retreated back to the Theocracy, the captain had a meeting with the Cardinals. In the end, to avoid unnecessary losses, it was decided to let the vampire be and have a standard observation team monitor it before gathering their forces and confronting it again. The Cardinals also figured that, if someone capable of defeating that monster were to appear, they would have to strengthen their national defense.[7]

The Theocracy declares neutrality in the Kingdom and Empire's Annual War

The Theocracy learned that the Baharuth Empire had formed an alliance with the newly-founded Sorcerer Kingdom, led by Ainz Ooal Gown, for their Annual War with the Kingdom. Not wanting to make an enemy out of him, the Theocracy sent a message to the Kingdom acknowledging his claim to E-Rantel and declaring neutrality in the conflict.[8]

Later, when a human boy threw a stone at Ainz while the latter was claiming E-Rantel, Momon believed he might have been [Charmed] and his action was part of a Theocracy plot to incite revolt.[9]

The Supreme Council meets

During a Supreme Council meeting, after learning of the Massacre at Katze Plains, it was decided that staying neutral in the Annual War was the right choice. Weighing their options, the Council decided that the Theocracy would continue to focus on their war with the Elf Country while sending spies to the Sorcerer Kingdom. They also wanted to bring former Black Scripture members out of retirement and dispatch them to the Dragon Kingdom as an aid.[10]

Later, Emperor Jircniv arranged a secret meeting with emissaries from the Theocracy in hopes of forming an alliance against the Sorcerer Kingdom. However, when Ainz Ooal Gown arrived unannounced, the emissaries assumed the Emperor had betrayed them and angrily left. Afterward, the Theocracy cut all ties with the Empire.[11]

The Black Scripture is sent to the falling Kingdom to rescue Adventurers

The Theocracy had sent several spies to infiltrate the Sorcerer Kingdom. Unbeknownst to them, however, the nation's leadership was fully aware of their presence, but chose to merely observe their movements for now.[13]

When the Sorcerer Kingdom went to war with the Re-Estize Kingdom, the Theocracy sent the Black Scripture to the latter country when its defeat was certain. However, rather than aid them, they were instead ordered to recruit adventurers by offering them sanctuary. In the end, while they failed to get some key individuals, many accepted the offer and migrated to the Theocracy.[14]

The Half Elf God-kin Arc

Main article: The Half Elf God-kin I and The Half Elf God-kin II Arc

Following the Kingdom's downfall, the Cardinals met for an emergency meeting. With the increasing encroachment on human territories by non-human countries, it was decided that the Theocracy must play an even more active role in the defense of humanity than it already was. However, they were once again confronted by logistical issues. On top of having lost contact with the spies they had sent to the Sorcerer Kingdom, the Theocracy's military was currently occupied with their ongoing war with the Elf Country. Therefore, to end the conflict as swiftly as possible, the Cardinals approved a plan to assassinate the Elf King.[15][16]


The Theocracy assassinates the Elf King

The invasion of the Elf Country was not only to avenge the honor of the Theocracy, but also out of a long-term plan to use the territory of the elves as a shelter for the Theocracy's civilian populace in the inevitable war with the Sorcerer Kingdom. Having already researched the elf trees used by the elves, the Theocracy intended to conquer the capital to use it to evacuate their people. However, the largest elf tree settlement was near Crescent Lake and they needed the city intact so the higher ups forbade their armies from devastating the area. The Theocracy eventually launched a full-out assault on the elven capital, overwhelming the defending elves despite the latter receiving reinforcements from their dark elven brethren.[17]

In the end, the Theocracy's plot was mostly successful, with the Elf King being killed and the Elf Country conquered. However, the Sorcerer Kingdom interfered in the war, which resulted in their asssassin being captured. They consequently learned of the Theocracy's involvement in the incident with the brainwashed vampire, who is one of the Sorcerer King's direct subordinates, prompting them to begin preparing for war.[18]


The Theocracy preaches human supremacy and the persecution of other "lesser" races. With its religion revolving around the Six Gods and their descendants, the Theocracy is effectively divided into six different religious sects, each with its own unique culture and practices. One factor all six groups share is that the names of the people in the Slane Theocracy consist of a given name, a baptized name, and a family name.

In Mass for the Dead, it was revealed that the Theocracy follows a seniority system. Unlike other nations out there, they do not possess a culture that aims for reward. Instead, the people of the Slane Theocracy live to express their faith.[19]

The current ideology espoused by the members of the Slane Theocracy, that only humans should flourish, and every other race is an enemy, even if they were humanoids, is not the original policy. This policy is comparatively new and has only been practiced for a century plus a few decades. Before that, the Theocracy also took the other humanoid races into consideration, upholding a policy that they should join hands together and fight against the other races. However, for various reasons, the vision of the nation was altered to this current xenophobic attitude.


In addition to worshiping the Six Great Gods, the citizens of the Slane Theocracy hold their descendants in veneration. The preservation of their gods' bloodline is of the utmost priority and they make an effort to ensure their legacy carries on to the next generation. To achieve this, the Theocracy practices polygamy. Not only is such a practice considered to be a rare occurrence, but the husband is also restricted to have two wives at most.

Another central part of the Slane Theocracy's religion is the Miko Princesses, who, by description, are the nation's religious figures vital in performing some of their important rituals. So far, there seem to be Six Miko Princesses, which are related to the elements of the Six Great Gods. Though seemingly an esteemed position of power, in contrast, it appears that the Miko Princesses are effectively living sacrifices. They are chosen from the population with great care and scrutiny, due to the items they are given from their pedestals, which pose many risks to the user.

In the Web Novel, the Six Miko Princesses comprise of the Miko Princess of Water, the Miko Princess of Fire, the Miko Princess of Wind, the Miko Princess of Earth, the Miko Princess of Light, and the Miko Princess of Darkness. Likewise, all of them are users of priest-type 5th tier magic, but this is a national secret.[20]

There also exists a special temple dedicated to the God of Water. Within this temple is a special chamber filled with water called "Eye of the Water God."[21]


Overlord EP13 110

The Six Cardinals of the Six Great Gods

As a Theocracy, the Slane Theocary is governed by a Pontifex Maximus with a position similar to that of an Emperor, elected in a conclave by the Six Cardinals.

The Pontifex Maximus is assisted by a board of advisers from the highest executive authorities in the Slane Theocracy, the Supreme Executive Council. It consists of the representatives of the Six Great Gods, the Cardinals, and from the government the heads of Executive, Legislature, and the Judiciary, plus the head of the Research Institute in charge of magic affairs, and the Grand Marshal as the highest appointment-holder in the military. The council sits at a round table within a sacred room where everyone is equal. There are no superiors or inferiors on the table, everyone is a collaborator and a comrade, including the Pontifex Maximus.

Overlord IV EP03 019

Six Cardinals in Conference

Cardinals are the highest appointment holders of the six sects that are devoted to the Six Gods. The position of a Cardinal is higher than that of a representative of governmental affairs; the demerit is that they get no wages so that people aspiring to become Cardinals would not be motivated to rise through the ranks by greed. Hence, there were many individuals who took high office with the intention of serving their nation. The current Cardinals are:

There were only two countries that had the capability to set up national-level organizations. One of the two was said to have been the Slane Theocracy.

Military Strength

The knights from the Slane Theocracy are said to be far stronger than those of the Baharuth Empire.

Additionally, there are God-kin among them with great influence over the country. These special individuals are viewed as demigods who are descendants of their ancestors known as "players." When compared to both the Kingdom's or Empire's clerics, the Theocracy's faith-based magic casters (clerics) are usually more skilled than any of them. The average skill levels in the Theocracy are generally quite high. Also, the Theocracy has at least five artifacts left behind by the Six Great Gods.

In the Web Novel, if compared with purely human countries, the Theocracy possesses the strongest national power of them all due to its powerful military presence. Let alone their national power, the Theocracy also has the top fighting ability on the continent than any other human country. For instance, they conduct military operations within the nations bordering the Theocracy with the intention of suppressing demi-humans and other races. On the other hand, the Theocracy is capable of conducting large-scale rituals or have the highest class of priest to cast resurrection magic.[22]

The Slane Theocracy is also shown to have access to the Six Miko Princesses, whose usage of the Crown of Wisdom allows them to perform High-Tiered Magic normally impossible for humans to use or achieve.

There are Six Scriptures, who are deeply rooted into separate branches of the Theocracy:

After losing the entire Sunlight Scripture, several Black Scripture members, Kaire, and one of the Miko Princesses alongside her Crown of Wisdom, one of the Six Cardinals estimated that it will take at least ten years for the Theocracy to fully recover their military strength.

Later, after the Fall of the Re-Estize Kingdom, the Theocracy's military forces has gained an immense growth in numbers and power due to the Black Scripture's successful operation of convincing several of the Kingdom's adventurers to flee and migrate from the Kingdom and into the Theocracy to save themselves.

Foreign Relations

The Slane Theocracy is one of the strongest human nations in the region. While there are various political and cultural issues with the other neighboring nations, many see the Theocracy as a necessary evil. In an ironic twist of fate, Theocracy's xenophobic actions allowed its neighboring to advance into their own societies, as they would normally have disappeared in the face of encroaching demi-human nations.

Dragon Kingdom

The Dragon Kingdom pays tribute to the Slane Theocracy in return for military aid in their war against the Beastman Country; a deal which the Theocracy honors. However, since the Theocracy has been unable to meet its obligations with the Dragon Kingdom due to a shortage of manpower, the Dragon Kingdom has turned to becoming closer with the Sorcerer Kingdom. To prevent their loss of influence in the Dragon Kingdom, the upper echelons of the Theocracy has planned to send military aid in the form of the many adventurers from the fallen Re-Estize Kingdom to fight the beastmen to help the Dragon Kingdom's defense and even allow them to remain there in order to strengthen the kingdom and reinforce its populace.

Elf Country

While the Theocracy and elves initially had a cooperative relationship, that ended when its reigning monarch kidnapped and violated the Theocracy's strongest Godkin. Ironically, however, this incident would become a boon to the Theocracy, as they managed to rescue the kidnapped Godkin and the child that was forced upon her ended up becoming even more powerful than her mother. Presently, the Elf Country and the Slane Theocracy are engaged in a war.

However, while the Theocracy's citizens seem to now view the Elves as sub-humans, with them having become favored products in the slave trade, the Supreme Council's grudge is not toward the Elves, but their king. In reality, they pity the Elves for having to live under a tyrant and even hoped for them to escape the conflict. To the end, this led them to approve a risky plan to bring the war to a swift end by assassinating the Elf King.

Once victory was within reach, the Theocracy began making plans on what to do with the annexed territory. Particularly, they wanted to turn the Elven Capital into an evacuation center for its citizens to flee to for the inevitable war against the Sorcerer Kingdom. To this end, despite their previous desire to spare the elves, the Theocracy decided to enslave most of the inhabitants.

Re-Estize Kingdom

In the past, the Theocracy secretly shepherded the Kingdom in the hopes this would allow humanity to grow and thrive, as well as produce several strong individuals. However, this backfired, as their relatively peaceful lifestyle caused them to become nothing but a cesspool of corruption that even the Theocracy wished to eradicate. Aside from this, the two nations also had problems due to religious differences.

The only reason the Theocracy did not conquer the Kingdom themselves was due to fear of retaliation by the Argland Council State. Instead, they planned to on having the Kingdom be conquered by the Baharuth Empire. To this end, while there was no open war between the Theocracy and the Kingdom, conflicts existed behind-the-scenes in the form of espionage and small skirmishes.

When the Sorcerer Kingdom went to war with the Kingdom, finally spelling the nation's downfall, the Theocracy made no effort to aid their neighbor. However, still wanting to salvage something of their initial project, the Black Scripture was sent to the Kingdom to recruit powerful Adventurers, hoping for them to continue to serve humanity. To do so, the Theocracy offered these individuals sanctuary within their borders, while not restricting them from immigrating to other human countries afterwards. In the end, while they failed to recruit adamantite level individuals, dozens of high-ranking adventurers accepted the offer. The Cardinals also wanted to retrieve the Kingdom's royal treasures, but this plan was abandoned due to a lack of manpower.

Overall, the Theocracy did not seem bothered by the Kingdom's downfall. They only worried about the former nation's territory potentially becoming a spawning group for undead and of the various covert operations that they had conducted within their borders being exposed.

Baharuth Empire

The Empire has made many appeals to the Theocracy for its assistance in sharing their teachings on divine magic. However, the Theocracy has yet to make any response back to the Empire's request on the issue.

In truth, the Theocracy has long been monitoring its activities and political movements and considered it to be the more successful nation compared to its neighbor, the Re-Estize Kingdom, which they considered a failure. Because of this, they planned to permit its conquest of the Kingdom.

After the massacre at the Katze Plains and the founding of the Sorcerer Kingdom, the Theocracy became wary of the Empire, as they allied themselves with an undead. The Theocracy thus sent an envoy to the Empire to confirm if Emperor Jircniv was still on the side of humanity. However, when the Sorcerer King walked in on their meeting, the envoys assumed the Emperor had sold them out and left. Afterwards, the Theocracy severed all ties with the Empire.

Argland Council State

Since their doctrine promotes discrimination against demi-humans, the Council State, a nation in which various species coexist, is seen as a great threat to the Theocracy. As a result, the two nations actively hate each other from a citizen's point of view.

However, both nations' leaders are aware of their military limitations and are thus hesitant to wage open war against each other, as that would most likely result in mutual destruction. In a way, this causes both nations to keep each other in check, with neither daring to overreach for fear of provoking the other. For example, the reason why the Theocracy did not conquer the Kingdom was because that nation existed as a buffer country between itself and the Council State and citizens would certainly want war if they were to suddenly become neighbors.

With the emergence of the Sorcerer Kingdom, the Theocracy's leaders briefly entertained the notion of an alliance with the Council State. However, that idea was almost immediately dropped since, even if they managed to defeat their mutual enemy, the two nations would then most likely go to war over the spoils.

Sorcerer Kingdom

So far, no official contact has been established between the Slane Theocracy and the Sorcerer Kingdom besides two small skirmishes during Nazarick's first emergence into the New World and Shalltear's clash with the Black Scripture.

If the Theocracy learns of the existence of Nazarick being a potential power base for unholy creatures who live there, it would mean great calamity for the human race. When Nazarick did reveal its existence to the world, claiming the large swathe of the Re-Estize Kingdom, the Slane Theocracy chose to remain neutral.

After E-Rantel was annexed by the newly arisen nation of non-humans, the benevolent actions of the Sorcerer King and relative peace of E-Rantel confused the higher-ups on how to proceed. Due to the reports about the power of its army, lack of reliable information, and the ongoing war with the Elf Country, they decided not to proceed any further on establishing any official conflict with that country for the time being. Instead, the nation decided to send its own spies to infiltrate the capital of the Sorcerer Kingdom to acquire more information about their situation.

Despite their general contempt for the inhuman nation, mainly due to its pro-equality stance for all races in contrast to the Theocracy's central human radicalization, the Theocracy has secretly cooperated with the Sorcerer Kingdom, regarding the inhuman nation's declaration of war of annihilation, against the failed state of the Re-Estize Kingdom.

Due to the Kingdom's massive corruption in its government and the degradation of its nobility in decadence from its relative peacefulness, the Theocracy had initially wanted the Baharuth Empire to conquer the Re-Estize Kingdom. However, ever since the Empire was assimilated into the Sorcerer Kingdom, that thought began to change and shift elsewhere. Learning about the Sorcerer Kingdom's declaration of international war against the Re-Estize Kingdom due to the foolish actions of a single nobleman, the Theocracy had quietly condemned their fellow human nation to its demise. They deemed and admonished the sheer stupidity of the one nobleman who was responsible for sparking the war to happen as a prime example of the Kingdom's failure. Seeing how this war would play out, the Theocracy instead decided to take advantage of the Sorcerer Kingdom's war by recruiting several of its most talented adventurers into their nation by inviting them to immigrate to their borders for their own safety. This operation was done by taking advantage of the fear the adventurers had knowing that they might become the next target of the Sorcerer Kingdom's invasion and be slaughtered together with the rest of the Kingdom. As a result, while the Sorcerer Kingdom was busy massacring the civilians, the Theocracy silently carried out their operation in the hopes of trying to strengthen themselves, having the kingdom's most gifted join the ranks of their military forces.

Ironically, the Slane Theocracy is the ones ultimately responsible for spurring the creation and public debut of the Sorcerer King and his Kingdom due to the Black Scripture's usage of Downfall of Castle and Country against one of the Sorcerer King's servants, motivating him to take more proactive/destructive moves against the various human nations in order to strengthen his defenses and hunt down the ones responsible without restraint.

As noted by the Ruling Council of the Theocracy, they are unsure on the matter of how to deal with the Sorcerer’s Kingdom, due to not knowing the full might of the inhuman nation’s military, whose overall strength has been compared to a bottomless black hole, the Theocracy itself is unsure of it is the wisest course of action to declare open hostility on them. Due to this , the Theocracy’s government has instead entertained the idea of becoming and submitting to them as a vassal state similar to the Empire and gain credible information on the Sorcerer Kingdom’s infrastructure and, from there, begin to weaken and destroy it from the inside. However, knowing that the normal citizens of the Theocracy, who did not have the same information available to them regarding just how dire their situation is as the Ruling Council did, they would likely never accept the vassalization and likely make the country descend into chaos by instead rioting in protest. This in turn has caused the council to instead consider allying with their long term enemy, the Argland Council State, to deal with the Sorcerer Kingdom. However, due to their long hostility to the Demi-human nation, the Theocracy knew that this was impossible or at least extremely difficult to make happen. Overall, the Theocracy has instead decided to settle their war against the Elf country before moving on to the Sorcerer Kingdom.

Roble Holy Kingdom

Relations between the two nations was a bit volatile due to some religious differences between them. However, they still share a common enemy: the demi-human tribes that live in the Abelion Hills.

After the founding of the Sorcerer Kingdom, which they considered a common threat, the two countries attempted to form an alliance against the non-human nation. However, talks were slow due to their religious differences and were most likely abandoned following the Holy Kingdom's swift change in perspective towards the Sorcerer Kingdom after the Sorcerer King personally saved their nation.

  • Unknowingly to the Slane Theocracy's higher ups of the connections between the incidents, their nation has already have had up to three altercations with the Sorcerer Kingdom, more specifically with the Sorcerer Kingdom's true core of the Great Tomb of Nazarick, each ending with a massive blow to the Theocracy's military that left their nation shorthanded. After the events of the Theocracy - Elf War, the Theocracy would suffer another one.
    • The First incident being Ainz Ooal Gown annihilating Nigun Grid Luin and the rest of the Sunlight Scripture and the loss of one of their national treasures. An incident that effectively caused the dissolution of the Scripture and left a giant hole in the Theocracy's military.
    • The Second incident being Ainz Ooal Gown, in his adventurer persona, Momon, killing and defeating the traitor and former Black Scripture member Clementine in battle and destroying the stolen Crown of Wisdom, a national treasure of the Slane Theocracy and a vocal point in their arcane military before they could retrieve the item.
    • The Third incident occurred when the Theocracy's strongest army, the Black Scripture, encountered an unknown Vampire, who was unknowingly a Floor Guardian of the Tomb, and suffering massive casualties with two members dead and a user of one of their God's treasure's being severely injured that eventually killed her days after during the scuffle.
    • After their agent successfully assassinated the enemy monarch of the Elf Country and won the war for them, the Theocracy would lose their strongest God-kin to the Sorcerer Kingdom after she attempted to unknowingly kidnap one of the Floor Guardians, who had witnessed her assassination of the Elf King.

  • Due to its age as the oldest surviving known human nation and its own deep ties to the Six Great Gods, the Slane Theocracy is shown to be perhaps the only Human nation to be aware of the periodical appearance of Players in the New World every 100-200 years or so. This is seen where the Six Cardinals mentioned the legends about the “Descent” of “Gods” every 100 years and refers to the event as the “Advent of the Gods”.
