- Sithis, referred to as a "great void", is a force representing chaos, change, and limitation. Sithis is described as an equal but opposing force to Anui-El, "the soul of all things", making Sithis is the antithesis of all things. Sithis Is Not. Unlike the many other personified deities in the series, Sithis is most commonly described as a "force" representing chaos and change.
- The Daedric Princes are alien beyond mortal understanding, though they can take any form they like, and so will often take a humanoid form to deal with mortals. Gender has no actual meaning to them and some appear as female, but they are referred to as "princes" as a whole. They also don't share the sense of "good" and "evil" mortals have. How they feel about the mortal races varies from Prince to Prince; many enjoy being worshiped, some just enjoy toying with mortals' lives for their own amusement, but all of them have demonstrated a willingness to reward mortals they find particularly helpful, loyal, or amusing. Some especially eldritch examples:
- Hermaeus Mora is the Daedric Prince of Knowledge, specializing in Things Man Was Not Meant To Know. Unlike most of the other Princes, he doesn't bother with a form comfortable to mortals and instead resembles a more typical abomination. In Skyrim, he appears as a "Wretched Abyss" — a living dark vortex. In the Dragonborn DLC, he appears in a truly mind shattering form with a seemingly infinite amount of tentacles and eyes. He also claims to be one of the "oldest" of a class Time Abyss beings, forming out of "discarded ideas" during creation.
- Behind Azura's veil of benevolence and pleasing female form, there are hints that she may be something much more eldritch. She may be a sort of 'cosmic force' of True Neutrality, primarily concerned with maintaining a sort of metaphysical balance in the universe. Her perceived "benevolence" is merely the result of her actions benefiting mortals more often than not.
- Like Azura, there is some indication that Meridia is something...more than what she appears behind her (intentionally chosen) pleasing female form and generally "good" actions toward mortals. According to the Magne-Ge Pantheon, the actions of the "Chrome Device" (implied to be Magnus or possibly Anu) have caused her "real" role in history to be lost. It also states "Of all of the Greater Spirits, it is Merid that we should most revere. For what if she forsakes us?" Further, she is the only one listed to have her pronouns capitalized in the work in the "God" with a capital "G" sense.
- The Hist are a race of ancient, sentient, hive-minded, giant spore-trees found in Black Marsh. It is said that the Hist were the original inhabitants of Tamriel, and that they were originally from one of the 12 "Worlds of Creation" that were shattered by Padomay and then coalesced by Anu to create Nirn. They are believed to possess "unfathomable" knowledge from the earliest eras of creation and even possess some sort of foresight into future events. They are worshiped by the Argonians, who claim the Hist gave them their souls, and are who are mentally influenced and physically altered by consuming the sap of the Hist. They are believed to be utterly alien and utterly incomprehensible, even for those who have achieved CHIM (a state of what is essentially awake lucid dreaming that can alter reality, and a full understanding of the universe), something which can't even be said about the likes of Hermaeus Mora.
- The Ideal Masters are mysterious immortal beings who were once powerful mortal sorcerers during the Merethic Era. After finding their mortal forms to be too weak and limiting, they entered Oblivion as beings of pure energy and settled an area of "chaotic creatia", forming the Soul Cairn. The Ideal Masters are most infamous for their trafficking in souls, especially "Black" sapient souls. All souls trapped in soul gems end up in the Soul Cairn and are considered property of the Ideal Masters. In the rare instances they do take form, they take the form of giant crystalline soul gems which can drain the souls of mortals who get too close. They possess a Horror Hunger for more souls, which they often sate by making deals with mortal necromancers that exchange souls for great power. (These deals also usually involve the souls of the necromancers themselves, though they may not be aware of this when they strike the deal.)
- In Morrowind, Big Bad Dagoth Ur and his Sixth House minions. He's using the divine powers he channels from the heart of a dead god to twist his followers into Body Horror abominations and spread a magical disease. Further, very much steeped in dream-imagery as he "sleeps awake" at Red Mountain. "The Dreamer Is Awake" is often found scrawled by the mad cultists in their strongholds. To further get into esoteric "lore speak": The implication is that Dagoth Ur has discovered an unspeakably dangerous middle-ground between CHIM, Amaranth and Zero-Sum where he exists in a godlike state because of his awareness of Anu's Dream but, unlike CHIM where he exists as one with it and maintains his own individuality, Amaranth where he exits the Dream to make his own, or Zero-Sum where he simply fades into the Dream, Dagoth Ur's twisted, traumatized and broken mind is being imprinted on the Dream of Anu. Through Corprus, the manifestation of Dagoth's will, he is turning Anu's Dream into his own.
- Alduin, Big Bad of Skyrim, is a draconic Physical God who is capable of eating the souls of the dead in Sovngarde and the only things that have been known to stop him are an Elder Scroll and the Dragonborn himself. There's a reason he's called "World Eater"; he was born to destroy the world. Lesser dragons are no less eldritch in every way save for their physical appearance. Dragons are ageless and ancient, having "always been," and possess immortal, divine souls. They cannot be truly killed unless that soul is absorbed by another dragon (or Dragonborn), and by using their magical language, they can cause small scale reality warping. The very concept of "finite", "mortality" or "entropy" is harmful to them. They might not even be truly dragons, but physical manifestations of aspects of the God of Time, Akatosh. Thus, they may be more like demons or angels than traditional reptilian dragons.
- The Numidium, a dwarven Humongous Mecha powered by the Heart of Lorkhan, the universe's "dead" creator god. Every time it (or a piece of it) does anything, it creates what are in-universe referred to as "Dragon Breaks," where reality and time is warped and can split into several different timelines that occur all at once. Examples of things happening in its wake include a mortal ascending to godhood, a section of Elsweyr being turned into a temporal toxic waste dump, a six-year siege being compressed into an hour, and an entire race simply ceasing to exist.
- The entire universe of the Elder Scrolls turns out to be this, once you examine and take apart its "hurling disk" structure.note The largest Dragon Break in Nirn's history occurred when an extremist cult attempted to change the nature of Akatosh, the god of time, by purging him of "unfavorable qualities." The ritual to do so apparently resulted in the destruction of the "hub" of the aforementioned hurling disk, resulting in an event called the Middle Dawn, during which the laws of reality needed to walk out of the room for a cigarette break. No one is quite sure what happened during the Middle Dawn, but accounts include gods walking among men, the sun changing color, battles that occurred for some being remembered as never happening by others, and children giving birth to their parents. The kicker? This went on for 1008 years. Not even the usually omniscient Elder Scrolls know what exactly happenned, with their glyphs simply disappearing then viewers attempt to look back that far, and the only method for determining how long the Middle Dawn lasted was by examining the phases of Nirn's moons, which, being made from pieces of the aforementioned "dead" creator god Lorkhan, were not susceptible for the influence of time and thus remained the only (mostly) certain constant.
