Corpus of the Abyss

Corpus of the Abyss is an undead organization that has been founded in the New World two hundred years ago.

Background
It was a group entirely made up of undead magic casters. Originally, this group had been formed to work for their mutual benefit and avoid conflicts. The reason for that was because the undead are treated as beings with unlimited lifespans, have the capacity to study magic together, and friction tended to develop.

Without these three great drives, undead invariably developed other, powerful desires, and in the case of undead magic casters, they generally tended to thirst for knowledge. For that reason, once a conflict over knowledge began, it would tend to escalate. Neither party would stop until it became a battle of extermination which would end with one side being annihilated.

If the three great drives of the living were concentrated into a single point, they surely see that single desire would become uncontrollable. It was very common for the undead to be destroyed in this way, to the point where the living could destroy both opposing undead beings while they were absorbed in their feud.

Knowing this, the undead eventually came to recognize that it was wiser to make trades and to cooperate with each other within reason, rather than fight to mutual extinction over knowledge and magic items. In the end, a list of names was made within Granisle Inscription to bind them together under an oath.

Once, it had many absentees in their meetings that were spaced years apart, but now they all met on a monthly basis. The undead had started meeting on a monthly basis at first, but as the number of members in their group fell, they were now meeting once every two days. Seeing everyone present at those meetings reassured them, but if someone was missing, the undead would worry that they would be next, and thus they would live each day in fear. Some of them had even started staying together.

In the end, the new conclusion was an unconditional surrender followed by begging for their lives. While some people had suggested fighting at first, they had all lost the will to go on and fight at this point in time.

The Vampire Princess of the Lost Country Arc
When Kunivela was considering the option of running away from Suzuki Satoru and Keno Fasris Invern, Corpus of the Abyss would have mocked the Night Lich's decision if they heard that he had abandoned everything and immediately chosen to flee. However, according to him, he would only have drawn that sort of reaction a year ago. Right now, the organization’s members would unanimously back Kunivela's choice and vouched for the rightness of his decision.

For a year, it was noted that some unknown being was slowly, gradually hunting down the organization’s members. Hence, the numbers in the group continued to dwindle over the course of passing time. It is currently unclear whether Suzuki Satoru was the person responsible for the killing of many members from Corpus of the Abyss since the undead beings in that organization he had known to only killed one so far was Granz Locke.

Strength
It is comprised of a group of undead beings who are skilled in spellcasting. Among those are beings who specialized in necromancy and belonging to a race of Elder Liches and Night Liches like Kunivela. In the past, there were originally four Night Liches and three Elder Liches within the undead organization.

Two hundred years later, it became a complete organization. Thanks to an increasing number of undead members that join Corpus of the Abyss over the course of time, the seven grew by 48, becoming a large organization with 55 members, with the original seven each being difficulty rating 150 undead creatures.

Each one of the members within the group have the strength to destroy countries. As powerful undead magic casters, they could take down a nation by themselves individually. Hence, everyone was known to act arrogant because of their tremendous power, which was why they rarely worked with each other.

Corpus of the Abyss had never worked together as a group. However, they no longer had the luxury to do so. Every undead in the group shared their information, looked out for each other, and joined their forces.

Currently, of its 55 members, 21 of them were completely uncontactable. This was not just limited to members of the outer circle, but even founding members of the inner circle. Ever since the death of Granz Locke, roughly, at least 40% of the group’s membership had been destroyed.

Types of Members
There were two kinds of undead who belonged to this organization. One kind cultivated their influence among the living and used them to achieve their aims. The other had nothing to do with the living, working quietly for their own aims in the world. Very few people thought like the former, so most of their members fell into the latter category. As a result, they did not cause many ripples in living society.

Known Members
