Spoiler alert, be careful and read at your own risk. I'll work on organization and finishing it at a later date. It's a work in progress right now
Let me know if I reference something that you don't know so I can add it to this list. Just tell me in the comments. This isn't a wiki of elder scrolls though just ideas and concepts and people that I think would be relevant to my story if you want to know more about elder scrolls, please go to https://en.m.uesp.net/ or the elder scrolls wiki for more information. I like UESP more for they are more detailed in lore but the wiki is great for the play-by-play in the actual Skyrim game, detailed information for quests

Concepts
Aedra
Daedra
Kalpa is a unit measurement of time essentially one epoch consisting of many eras after a kalpa is finished alduin is supposed to come in reset the world by devouring it and let it start over from the beginning to begin a new kalpa
Sovengarde the equivalent of heaven for the Nordic people it is essentially analogous to Valhalla in the sense that instead of being based on how good of a person you are, you are judged by your deeds and strength of arms be it weapon craft or magic craft both are OK to be tested on for entry by tsun who guards the whalebone bridge preventing you from passing to the halls of valor or shors hall until you are tested to feast and make merry until you are called on for the final battle
The void
Dragonborn
Gods/powerful entities.
Akatosh head of the imperial pantheon dragon god of Time and very concerned with keeping the current state of Tamriel going since everyone is currently worshiping him as the head God and he likes the current state of things. His son alduin in the near future (from a gods perspective) is gonna cause them all sorts of problems like eat the world so he wants to summon a dragon born to stop him
Alduin was created by Akatosh tearing a major piece of himself off and reshaping it into an immortal dragon god. His power level is between a normal god and a demigod so a minor God when he completes his divine duties. Due to him deciding to end the kalpa early, he has been can no longer use all his divine powers because he's not serving his purpose anymore. He tries to gain back his powers by devouring mortal souls of the Nordic heaven sovengarde
Sithis is neither aedra or Daedra but a primordial entity/sentient concept of change and destruction that came before the creation of the world as we know it and came to reside in the void which he considers his home and turf. in addition to what he's known for in the elder scrolls, he is the watcher of the void, the gatekeeper who protects aurbis from malevolent entities that are too strong and too curious about our world. This is why the other gods and Daedra put up with him and his murder hobo cult called the dark brotherhood and sentient trees that worship him called hists. His duty is too important and he's really Strong nobody wants to get beaten up by him in a one on one fight. He is known as the dread father and the creator of Shor/lorkhan
Magnus the god of Magic and the architect of mundus after creating the blueprint of the mortal realm and working on it's creation he decided to leave and head back to aetherius to work on his next project, he's kind of like a magician scientist architect God all rolled into one. think of him like the architect in the matrix
Shor/lhorkan/shezarr the God who have the idea for the creation of the mortal world and the process of creating the mortal plane borrowed power from some of the other gods which was invested in creation turning some of the gods into what is known as the aedra some into lesser spirits and some even into mortals this pissed them off and they decided to kill him, but he tied himself mundus turning his heart into the heart of the mortal world a linchpin of sorts so they couldn't destroy his heart and completely end him. They instead tied it to an arrow and shot it deep into the sea, which eventually became the red Mountain island volcano. He tricked the other powerful beings into investing their divinity/magic/essence into the creation of the mortal realm those that were the most powerful after their loss in strength became the aedra known as the 8 divines those that lost more strength became the ehlnofey the ancestors to the elves and those that lost the most strength became the races of men.
He is credited for the creation of the world, tricking other spirits out of their immortality gods of part of their power and being the father of mankind.
Kyne/kynareth the wife of shor and the mother of men and beasts she's associated with the sky and you can refer to her as the wind Mommy!
Mortals important characters and groups

Less Important characters and groups
Magic Items and artifacts

Other things like items plants and animals
Locations
The void. The mostly empty nothingness where aurbis and and other dimensions like earth reside or are manifested/projected. You can use the void to travel from one universe to another. It is the realm in between. That which resides outside of reality and there's plenty of castoff things there from relics of Bygone civilizations and worlds to Detritus and junk. It's the easiest way to travel from one universe to another but be wary of beings that reside in the void plenty of them are malevolent and curious about things they don't know and for some reason, a lot of them have tentacles or what your mortal minds perceives as tentacles due to your delicate sensibilities. Be ware the tentacular horrors actually it's best not to think too much on the subject. Occasionally void storms consisting of intense void energy cross the void like a normal storm. Please avoid them.
Aurbis the name of the elder scrolls universe that sits in the void
mundus the mortal plane and all the planets it contains
aetherius the immortal realm, heaven equivalent or positive plane where Magnus and the magna ge immortal powerful spirits/godlike beings reside. It pulls energy from the void and turns it into Magicka or magic particles which then bleeds into other realms like mundus who's sun and stars are also tears in the fabric of mundus leading to aetherius. Through these tears come magical energy which then saturates the mortal world
oblivion is the collective term for what can be considered the opposite of aetherius, the negative planes or in some cases the hell equivalent (a # of them are made of fire and brimstone). It consists of 16 known major realms ruled by Daedric princes minor realms where other Daedra reside and pocket realms. There isn't a fixed number of pocket realms some aren't stable and disappearing, and others are being generated. The number seems to be growing overall and the last time somebody actually checked they numbered around 37,000 Pocket realms in total. Good on you person or entity who took the time to count 37k dimensions.
nirn is the planet in the mortal plane mundus where the story takes place
tamriel is the continent on nirn where the story takes place it is considered central to the elder scrolls franchise, and is where the empire rules. Other continents include but are not limited to Atmora where the humans are originally from and Akavir the magical Asian equivalent in this world
Skyrim is the province/country where the game elder scrolls Skyrim takes place is the home of the Nords traditionally and previously the snow elves or Falmer who were kicked out/butchered by the Nords until they had enough living space for themselves. It is a cold land for a hearty people full of magic and mystery and ancient ruins to explore.
