The Soul Cairn mentioned by the noble lady Valerica is a realm in Oblivion filled with the souls of ensnared mortals. This place is not controlled by any demon, but by a group of mysterious creatures who call themselves the Ideal Masters.
It is said that when a person's soul is captured by the Black Soul Stone, the soul will be transported to the Soul Cairn and wander forever. The Lords of Thought believe that by liberating humans from their mortal bodies and gaining immortality, they will escape meaningless suffering and gain peace.
Therefore, the Soul Cairn is filled with all kinds of undead creatures. Some are unique here, such as the Bonemen, Mistmen, and Wrathmen. The powerful magicians on the mainland once used magic to summon the undead creatures here without alerting the Lord of Thoughts. But these ancient magics have been lost. In fact, in order to satisfy his endless desire for souls, the Lord of Thoughts often makes deals with the Necromancer. In exchange for their souls, the necromancers were given the right to summon undead armies from the Soul Cairns, although they were often trapped by the Lord of Thoughts, and eventually their souls ended up in the Soul Cairns.
Normally, mortals must die in exchange for passage to the Soul Cairn. But it can also be achieved by sacrificing part of one's soul or transforming into an undead creature. This place could have been entered through the Void Gate in Battlespire, but since the destruction of Battlespire, the Oblivion Passage has been cut off.
As for the evil existence that rules the Soul Cairn, a plane of annihilation—the Lord of Thoughts. It is said that they usually do not show physical form in cairns, but prefer a "ubiquitous" spiritual form. However, there are always exceptions. The Thought Lord will also appear in the cairn in the form of a giant soul stone. This soul stone acts as a conduit, allowing the Thought Lord to communicate with or drain the life essence of any mortals who come near. The Lords of Thought are always searching for powerful souls that can be brought to the Soul Cairn and imprisoned here forever. They regard this as an eternal peaceful life, but the undead imprisoned here regard it as A permanent curse.
The Thought Lord possesses the true word, but the name is too high to be pronounced. While they proudly call themselves the "Creators of Soul Cairns", they also humbly claim that they are also mortals.
Scholars speculate that the Lord of Thought is probably a "Demiprince" whose ability is second only to the 16 demons in the field of annihilation.
In the rumors among ancient wizards, the Lord of Thought was impolitely called the "Spirit-Eating Demon". During the Age of Mythology, they were a group of powerful wizards who appeared in Nirn. Later, they found a way to be promoted to Demon Gods and gave up their bodies and became the masters of the Soul Cairn, a plane of annihilation. Since the origin of necromancy is closely related to the demon god Molag Bal, and the demon god could travel through Nirn at will during the Mythic Era, these wizards may have taken refuge in Molag Bal. At the same time, the atmosphere of the Soul Cairn is very similar to that of Cold Harbor, which can also confirm this. During the Fourth Age, the Mythical Dawn who believed in Merunes Dagon used the power of the "Shax Codex" written by the devil to create the annihilation realm "Giaar Alata" and the leader of the Mythical Dawn Order, Mankar. Camoran's failed attempt to ascend to the devil is also an example of this behavior.
To put it simply, the patron saint of a necromancer wants to see the lord.
"Why does the Lord of Thought want to see me?" The Lord did not dare to be careless.
"Sir, I don't know the specific reason. But it must be related to the current crisis." The noble lady Valerica told the truth.
"Master, this seems to have nothing to do with our adventure." The housekeeper did not recommend that the lord take unnecessary risks.
"It's related." The next words of the noble lady Valerica made the lord unable to refuse: "There is an undead dragon Dunevir in the Soul Cairn. The Lord of Thought said that only you can save her, my lord."
"'She'?" Wu Chen asked, obviously with deep meaning. Due to convention, genderless dragons call each other "brothers". Only in the Gray Stone Castle would the feminine "third person" "she" be used to refer to all the demonic light-transformed and Ximu Longniang who are about to be transformed into the demonic light.
"Yes, sir. These are the original words of the Lord of Thought." The noble lady Valerica nodded solemnly.
"Then give me this dragon." Just kidding, how could the lord refuse a dragon?
Durnehviir, an undead dragon, whose name means "Curse (Dur), Never (Neh), Death (Viir)" in dragon language.
During the Age of Mythology, when dragons took control of Tamriel, Duneviel fought in many wars as he fought with other dragons for control of the skies. She delved into "Alok-Dilon" instead of ordinary fighting methods. Like many great necromancers, she approached the Mind Lord in an attempt to gain his favor. They gave her the power to summon undead armies from the Soul Cairn, but in return she must spy on Valerica, a vampire trapped in the Soul Cairn by the Lord of Thoughts. The Lord of Thoughts did not tell Duneville that Valerica was an immortal vampire, in fact, he tricked her into being a slave forever. So many years later, Duneviel's body gradually merged into the Soul Cairn, making it impossible for her to return to Tamriel.
According to the original plot line of "The Elder Scrolls", in 4E 201, the last Dragonborn and Serana came to the Soul Cairn to look for Valerica. Duneville was awakened and began to attack the intruders. He was eventually killed by the Dragonborn, but due to the protection of the Lord of Thought, his soul was not devoured and he was resurrected again. He hailed the Dragonborn as "Qahnaarin" or "The Conqueror". Duneviel even connected himself with the dragonborn's soul. Allows the dragonborn to use the Summon Durnehviir spell to summon her in Tamriel - briefly leaving the Soul Cairn and gaining the coveted freedom. In return, Dunevir fought for the dragonborn and taught the dragonborn a witchcraft called "Soul Tear": absorbing the souls of enemies killed by the dragon hole to charge the soul stone and summon the enemy's corpse. Become a ghoul.
Although Duneviel had repaid the Lord of Thought's favor as agreed, he was still trapped in the Soul Cairn forever.
In fact, many of the subsequent plots experienced by the Lord after returning to Ximu are the contents of the DLC released one after another for "The Elder Scrolls 5: Skyrim". As the original plot line, "The Elder Scrolls: 5 Skyrim" is an old adventure that he and the housekeeper experienced together. These scattered plot fragments will appear out of thin air in the form of memory copies when the lord touches them again.
"Then, go and meet." After listening to the noble lady Valerica's story, the lord decided to go to the Soul Cairn first to meet with the Lord of Thought.
Since the ancient snow elf paladin Jelebor cannot break the annihilation storm covering the Forgotten Valley, he might as well listen to the Lord of Thought's opinion.
"Yes, Lord Baron." The noble lady Valerica and the eldest lady Serana both breathed a sigh of relief.
