Black Scripture is the Slane Theocracy's final trump card, a special forces unit comprising of individuals with heroic-level abilities. One could even think of them as a group supposedly made up of adamantite-ranked adventurers. However, there was actually a critical difference that sets the Black Scripture apart from most adamantite adventurer groups, that of their equipment used by each of its respective members. In other words, they're utilizing the equipment that originated from the arsenal of items belonging to the Six Great Gods. While so, the Black Scripture are commonly assigned to very dangerous tasks, and so they had a very high attrition rate.
Their title as the mightiest unit within the Slane Theocracy and their black motif directly correlate with them following the teachings of the God of Death of the Six Great Gods, Surshana. Not only is their Death God the most powerful of all the Six Great Gods, but their group as a whole also holds the greatest fighting power than all the other Five Scriptures too.

The Witch of the Falling Kingdom Arc
- Main article: The Witch of the Falling Kingdom Arc
After the Kingdom went to war with the Sorcerer Kingdom, which the former would surely lose, the Theocracy deployed several members of the Black Scripture, led by Quaiesse Hazeia Quintia, to the doomed country. However, rather than coming to the nation's aid, they were instead ordered to recruit powerful adventurers to the Theocracy's cause in exchange for escorting them out of the Kingdom safely.
One of the adventurer groups they approached was Blue Roses, alongside Red Drop's Azuth Aindra. Unfortunately, talks between the Black Scripture and Azuth instantly broke down when the latter keep bombarding the secret organization with confidential questions they are not open to neither talk about nor answer it. Similarly, all the members of Blue Roses have also turned down the Black Scripture's offer, instead choosing to stay behind and defend the Kingdom. In the end, although the Back Scripture failed to recruit the Kingdom's two adamantite-ranked adventurer Groups, many other adventurers did accept their offer as planned.
After Azuth made a mocking statement about Rufus and his connections to them and the Theocracy, the Black Scripture quickly turned hostile to all the adamantite adventurers present in the room. It was said that the members of the Black Scripture did not lower their guards since then as they left the meeting room. They maintained that kind of attitude in a way if the group of adventurers was to take any sort of action on them, they would retaliate in kind.
With the meeting over and done with, the Black Scripture made it their plan to report and relay what Azuth of Red Drop have said to them to the higher-ups when they return back to their nation.
While part of the greater whole of the Slane Theocracy, the Black Scripture has its own separate culture that reflects the edicts of their patron god respectively. According to the laws dictated by the Six Great Gods, someone over the age of twenty will already be considered an adult in the Theocracy. Thus, when the junior Black Scripture members go out on missions, they would wear magical masks to conjure a fake face.
Additionally, when the time came for a new Shaman Princess to replace their old one, the job of the Black Scripture was to remove the Crown of Wisdom from its current wearer. Thereafter, they would then promptly send off the now-insane Shaman Princess to be with the Six Great Gods. In other words, the Black Scripture is tasked with the job of killing the previous user of that item once they served their purpose.
During important missions, the Black Scripture is also apparently given the authority to use the powerful "Divine Equipment" left behind by the Six Great Gods of the Theocracy for vital assignments and the Scripture members are given the added duty of protecting the Item's user during their missions until its power can be activated. As seen where they were assigned to protect Kaire during their mission to subjugate the Catastrophe Dragon Lord when she activates the Item power in order to bring the Dragon Lord under their control.
Black Scripture is considered to be the strongest group among the Six Scriptures and consists of members who have reached human physical limits and possess heroic level strength. In other words, Black Scripture is the strongest of all combat groups working within the Slane Theocracy and its pride. Unlike the other Scriptures, each of its members focuses on a specific type of combat or skill and is comparable to a whole combat group. They will usually carry out their missions alone, but will still work together if ordered by their captain.
According to Nigun Grid Luin, only the Black Scripture could eliminate this many Archangel Flames like Ainz Ooal Gown is a demonstration of their group's strength. However, unlike Ainz, he had doubts that any of those members from the Black Scripture would be able to take care of all these angels with just one spell. 
The highest-ranking and strongest members of the Black Scripture are thought to be demigods, because of their immense powers and the fact that the blood of the Six Gods runs with-in them. Upon meeting them, Shalltear Bloodfallen estimated the strength of their group's leader to be superior to Solution Epsilon, a member of the Pleiades. The cardinals stated that the Black Scripture can use a grand ritual to summon the highest-ranked angel in case their group's strength isn't enough to eliminate a threat.
During the meeting of four members of the Black Scripture with Blue Roses and Azuth Aindra, it was immediately noticed by the Adamantite Adventurers that each and everyone of the four members' individual strength alone far surpassed theirs by a wide margin despite their own immense power. Thereby showing that a single member of the Black Scripture has power equivalent to a team of Adamantite Adventurers.

- In the Web Novel, Ainz resembles the God of the Black Scripture, Surshana.
- In contrast to the Web Novel, there are only eleven seats in the Black Scripture.
- Evileye explains that the Black Scripture are thought to be demigods as those with the blood of "Player," yet it seems that she just thinks that "Players" are a special race that is immensely powerful.
- According to Maruyama, someone from the Black Scripture would be regarded as the strongest paladin in the region before one of Enri's Goblin subordinates and Remedios Custodio.
- Barring Extra Seat and 1st Seat, distinction in power among the seating members of Black Scripture does not so much match the number order they're placed at.
- During the failed negotiations with Azuth Aindra, he implied that one of the high ranking superiors to the seated members is an undead. He seems to know that its existence and status as both an undead and superior to the Black Scripture is something that should not be general knowledge to outsiders. It was later implied that if leaked, this information could potentially threaten the national safety of the Theocracy, seeing as members of the team were ready to kill Azuth Aindra and all the members of Blue Roses when he spoke of him in order to insure the details on the undead remains hidden.
- It was later confirmed that this undead holds a very high position within the Black Scripture and is a superior to the seating members.
- Later after the failed assassination attempt on the Sorcerer King, it was revealed that the Platinum Dragon Lord was the one who gave Azuth the info on the undead.
- Within the Black Scripture, if a member's seat happens to be left vacant, it is probably due to the former holder of that position have either retired or died during a mission. Thus, outside Black Scripture's current members, there are also the retired members. Those retired members are still heroic ranked, but their physical abilities have degraded with age.
