The Next Game will take place in ArgoniaNear the end of the Thalmor war. Skyrim, Morrowind, Hammerfall and Cyrodil have fallen to the Thalmor, and those who oppose the Thalmor form a resistance, operating out of black marsh whose military and natural defenses have kept the Thalmor at bay.
The Elder Scroll's MultiverseAs we all know, Akatosh, while a benevolent god, is Insane. Let's just assume that this insanity manifests as multiple personalities, innumerable personalities. Akatosh is time, so each personality would have it's own individual timeline, where any number of things could be different than the others. Everything would be split, Tamriel, Nirn, Mundus, even Oblivion and Aetherius. Akatosh, being King and Time itself, would be the only constant. Aaand Boom. I just made a theory linking every last player of Elder Scrolls together.
The player is not a single characterThis regards Oblivion in particular, where the titles we can hold and roles we can play are kinda disjoint. It's not impossible to rationalize the holy Crusader of the Nine Divines being one and the same as the murderous Listener of the Dark Brotherhood and the new god of madness at the same time, especially if you subscribe to the school of thought which holds the Champion of Cyrodiil went insane during the Oblivion Crisis and became a bipolar and amoral force of nature. On the other hand, the dramatic variations between questlines in both aptitude and moral disposition make me skeptical. Would leadership of the Mages' and Fighters' Guilds really be held by the same person? Is that even allowed? By my estimation, there could have been about five talented young adventurers running around Cyrodiil during that last year of the Third Era. What do you think?
The Aedra and Daedra are constantly fighting this huge offscreen war over who should control Mundus.Kinda hard to believe that beings of the same order, yet of two different origins would get along after what Lorkhan did. The Aedra believe that since they made the world, it's theirs, but the Daedra feel that since one of their own inspired the creation of said world, they get special dibs.
Nirn has a massive firey being in it's coreKeep in mind, in TES the stars and sun are actually holes poked in reality and not burning balls of Hydrogen. Dwemer ruins clearly have steam, and it seems the Dwemer had usage of Geothermal energy. My theory is that some sort of firey, volcanic being is in the center of Nirn providing said heat.
Humans aren't native to NirnThey are actually from Earth, they were abducted to Nirn over the centuries by the Dwemer and Daedra. Previously the planet was inhabited by the Dragons and Ancient Aldmer (who would diverge later on). Humans (particularly Nords and Redguards) are distrusting of Magicka because it was used by the Mer to subjugate them. Somewhere along the line humans began to out number many of the Mer groups (such as the Orcs). Forming the Tamiel we know from the Elder Scrolls series.
The PC in nearly all the The Elder Scrolls games are the same person.
The next game will take place in more than one province.With PS 4 and the next Xbox on the way, there's nowhere for the Elder Scrolls to go but even bigger, and the only remaining areas in Tamriel are much smaller than Skyrim, Hammerfell, Morrowind, and Cyrodil. The only way to keep the series expanding and uphold its state-of-the-art reputation is to set the game in multiple areas, rather than forcing the customer settle for less.
Jauffre is the Eternal Champion.He is about the correct age, and probably did a lot of cool things to get to his position.
Centurion was a dwemer brand.Most if not all dwemer constructs included in any game have the word "centurion" in their name: steam centurion, centurion spider, and so forth. This is very definitely a Nonindicative Name since, well, centurions are officers (literally "leader of hundred men"), meaning one might as well name their robot army Sergeants. It does, however, make perfect sense as the name of a highly popular forging company, offering advanced constructs and other defense mechanisms to protect and serve dwemer and their interests around the world. You deserve only the best to secure your home and workplace from the inferior species: choose Centurion!
The Guards in Oblivion are telepathic Humunculi.No matter where or when you commit a crime as long as there someone watching they come, even if horses are the only witnesses they come. They also seem to be able to communicate at distance and interrogate horses.
The Night Mother, Sithis, and Mephala are all the same beingnot sure how to better explain this one but considering that Mephala is hardly consistant even in the matter of its gender and it enjoys messing with people why not for a little amusement cause a schism amongst its own people?
Between II and IV, some mage discovered how to use Restoration Magic to cure baldness.This explains why the Emperor is bald in II, but has long flowing hair in IV. It also explains why there are no cut-balls in IV.
The Imperial City Dungeons double as a homonculous-producing facility.This explains why heroes often start off in prison with no backstory; they were created in prison. This also explains why there are no children in Cyrodiil; everyone is spawned in the Dungeons, fully-grown. It also explains why they can't take off their underwear, as they don't need to use their reproductive organs to reproduce (and note: in Daggerfall, you could strip totally naked, and male characters had no genitals.) And last but not least, it explains why soldiers and certain other types of people look identical to each other: those strains of homonculi are mass-produced.
Dagon's promises are all empty, and everything he says is a lie.Mehrunes Dagon's lovely promises of greatness and ascended mortality to those who follow him are all bunk. He doesn't mean any of it; that silly book he wrote is just his method of manipulating foolish mortals and tricking them into helping him take over and destroy the mortal realm. Had the heroes of Arena and Cyrodiil not stopped him before things could go that far, he would have betrayed his faithful mortal servants and slaughtered them too.
Why Claudius Arcadia wanted Rufio dead.If you talk to Rufio before you kill him, he refers to a women who he harmed in some way. Perhaps she was related to Claudius Arcadia, or was even his lover, and he wanted revenge.
The Arch-Mage in Oblivion has a secret.He's a vampire, a listener for the Dark Brotherhood, an escaped convict and the Grey Fox.
Who are you, at the end of Shivering Isles?Gosh, I guess this just isn't Wild enough for Wild Mass Guessing... but, I'm gonna say it anyway: at the end of Shivering Isles, you begin a transformation from mortal to immortal Daedric Prince. Like the final boss says, "Mortal? King? God? ...Perhaps you will grow to your station." Clearly, he's implying that you are (or may) become something more than mortal. Your powers are weak, sure, FOR NOW! But you still have the ability to change the nature of your realm... somewhat. And smite fools... a bit. And, let's not forget that you are immortal. Not only thanks to that weak-ass 'teleport back to the throne' spell, but also because if you die, you can just reload a save! Totally immortal!
Jyggalag was always the Prince of Madness
The Mannimarco who appeared in Oblivion was an Impostor
The Falmer will play some kind of role, in absentia or not, in Skyrim.
The guards in Daggerfall are artificially produced homunculi made from the same person
The Dragon that you can summon towards the end of Skyrim will be Martinfrom Oblivion
The Elder Scrolls VI will feature the hero saving the whole of Tamriel from the Thalmor
The Champion of Cyrodil was supposed to be Emperor
The Deadric realms of Oblvion are connected via a World Tree scenario.There is some large interdimensional organism-like thing which every one of the realms of Ovlivion are anchored to. It is this "tree" that holds the realms together and it's magic is what allows the Deadra to remain immortal. The Aedra made great sacrifice to create Nirn, however the Deadra are still dependant on this "tree," though they may not know it. If any realm were to be cut off from it in some manner both it and any that reside in it would cease to exist, swallowed up by Sithis.
Unrelenting Force will return in Elder Scrolls VI as a Greater Power for the Nords.Because knocking guards around with nothing but your voice is just too awesome/hilarious to keep to just one game.
Climbing will return in a later game as an Argonian ability.Because lizard ninjas.
M'aiq the Liar is a powerful Daedric prince with Dungeon Master qualities and is manipulating the events of at least the last 3 games.Like he says in Oblivion, he knows much and tells some. The point is, his knowledge goes much deeper than even the most wise scholar could dream of. Its so deep, that when he tells something, this knowledge changes the world enormously. For example, during Oblivion, he told the player that throwing weapons is foolish, because when holding your weapon you only need one. This causes the entire continent of Tamriel to forget how to make throwing weapons. He also told Levitation is for fools...and the levitation act is signed, outlawing it. And cryptically makes clear the player will see a dragon, resulting in the main quest ending. In Skyrim he even starts to get freakier. He appears at the most random locations, as if he is observing you from a distance. He calls mudcrabs 'horrible creatures' turning them into threats to low-level players. Then he decides to practically doom Tamriel by saying dragons were never gone, only invisible, which causes Alduin and his lackeys to go on a rampage. One can only hope he will not utter knowledge about the end of the world...
There will be a Skyrim expansion set in MorrowindThe events of the Infernal City novels basically trash Morrowind as a whole plot point. Red Mountain erupts, Argonians invade, and the Dunmer are forced to evacuate pretty much the entire province. Starting a Dunmer character in Skyrim prompts Hadvar to wonder if you are "another refugee", presumably from said events. The current state of Morrowind can easily be written into the backstory of an expansion. The Nerevarine could even make an appearance, being made immortal during TES III.
The Champion Of Cyrodiil was driven crazy by watching the world fall apartNot getting into why the new Sheogorath looks like the old one, one could imagine that the hero, now immortal and an eternal witness to the fate of the world, had to watch as the Empire fell apart, the provinces break apart, Morrowind suffer near destruction, their own efforts practically spat on by a group taking credit, and in general... everything they fought so hard for crumbling away into nothing despite their best efforts. The new Sheogorath isn't crazy and jaded because of some inherited madness, but because of the stress of it all. At least in the Shivering Isles, things are more constant and he/she is better in control of everything.
There will be a Skyrim expansion set in Bruma.Bruma, as seen in Oblivion, is culturally and environmentally similar to Skyrim, with a healthy Nord population. As such, it's possible that the Stormcloaks would want to capture the county and annex it into a hold of Skyrim. Or more likely, this would be a DLC quest, since it probably isn't big enough to warrant an entire expansion pack.
M'aiq the Liar is a Time Lord.In Oblivion, M'aiq says he's seen dragons, but he won't say where. He already experienced the events in Skyrim, then used his Type 70 TARDIS to travel back to the Oblivion Crisis.
The Dwemer were Time LordsThey had highly advanced technology, and were considered the most advanced race in the history of Tamriel. They knew how to make boxes that were bigger on the inside (as seen in Skyrim's main quest). They had steampunk, clockwork cities. They were Abusive Precursors and they all disappeared without a trace, supposedly due to meddling in things they aught not have. For all we know, their disappearance was Time Locked by M'aiq.
The Player Character is the reincarnation of the same person in all the Elder Scrolls Games.In Morrowind, we are told that the 'Player Character' is a reincarnation of a Chimer (Dark Elf) Lord named Nerevar. This wasn't the only incarnation for this character. The Prisoner at the start of Oblivion is another reincarnation. The Prisoner at the start of Skyrim is another. The prisoner at the beginning of Daggerfall was a past one. Its the same guy/gal coming back time and time again like a cosmic trouble shooter. This makes Nerevar truly a Hero of Another Story from a "lost" Elder Scrolls Game that never got made (with the first battle against Dagoth Ur being the final boss battle).
The Elder Scrolls 'Verse is literally an RPG 'VerseThis is a little hard to phrase, but bear with me. The Elder Scrolls universe in reality was adapted from the creators' D&D campaign. But the series does not take place in its own "Universe", but rather we are seeing what life would be like for actual characters in an actual RPG universe. First, the PC literally does not exist until you create him/her at the start of a new game. No history, no family, no friends, no background whatsoever other than "race" and "class". Second, the Multiple Choice Past of the world's history means that history is flexible. Only possible with a GM-induced Retcon. Finally, and most important: The Elder Scrolls themselves. Even Paarthunax can't easily explain what they are, only that they are "fragments of creation" and "come from outside time". They can't be comprehended by the people living there. What are they? They are the GM's notes.
Dwemer Metal is actually Conundrum mixed in with something elseThe "Secret recipe" used in making Dwemer metal has been lost in time, as well as the Dwemer. In Skyrim, underneath certain Dwemer ruins is "Blackreach", where Geode veins can be found. This COULD be their source of metal! You can only find Conundrum, Gems and Soul gems (which they could of used to power their machines). Conundrum and Dwemer metal are also a similar colour to each other.
If "Elder Scrolls VI" is kept to one province, it will be the Summerset IslesWar with the Dominion is all but a foregone conclusion by now (expect a Yol Toor Shul-sized Internet Backdraft if it isn't). The only question is whether the war will be Skyrim DLC or (as guessed above) the next game itself. Either way, Men weren't allowed on the Isles even when the Altmer were good guys, so a war/post-war occupation would be a perfect chance for Bethesda to have a game in that province and still have Men as PC's.
Martin becoming the Avatar of Akatosh was the equivalent of The Second Coming for the people of the empire.Notice how in Oblivion alot of people had lost faith in the Aedra and gone to the Daedra. No one is like that by Skyrim, so Akatosh actually coming down managed to convince many people to stay faithful.
Vivec's first mom is also a robot/cyborgVivec's first mom is possibly built by Sotha Sil or otherwise master-crafted to be able to carry Egg!Vivec inside. She also stays intact despite all the Dwemer efforts to get Egg!Vivec out of her. The prayer that Vivec gives her is probably some kind of shutdown signal, as he figures out that if the Dwemer don't remove him then he is gonna be stuck there forever. The Dwemer, being who they are, are so fascinated by this Robot Girl / cyborg that they try to duplicate her, although their simulacrum doesn't work as well and therefore breaks down. It's possible that the eighth monster-child, GULGA MOR JIL, is likewise related to Vivec's first mother. It has the exact same shutdown signal.
Elder Scrolls VI will be in HammerfellBethesda may want to replicate Skyrim's Awesome-Not-Strictly-Magicka system, and since the thu'um is a thoroughly Nord matter, just transplanting it to another province would be odd. But the Redguard have had this thing called the Way of the Spirit Sword, mostly lost in the modern day. Add in some reason for the player character to have a natural ability to jump the learning barriers (as Skyrim had for the thu'um via the Dragonborn thing), and some extension of the Shehai/Ansei's implied not-quite-swordly abilities, and it's perfect.
The heroes in every game is a reincarnation of the previous one.Not sure how it works completely, due to some time issues between the first three or four games, due to time issues.... It'll either be Time Lord style, or the reincarnation style from Avatar: The last airbender.
The Elder Scrolls is a prequel to the Fallout series and the magic is gone because of a major apocalyptic eventThe events of the Elder Scrolls happened so many thousands of years ago that Earth doesn't have any memory of that civilization's existence beyond mythology and tales that were passed down through multiple generations. Some sort of apocalypse happened that destroyed most of the magic and through evolution humanity became the dominant species as the others died out. How then does Fallout tie into this? Nuclear power. As it turns out nuclear power is a type of magic that was left over from the apocalypse and humans through science weaponized it by turning it into a bomb, unknowingly utilizing power from their ancestors' era. That is why radiation transforms humans into things like Ghouls or Super Mutants, and animals into special versions of themselves (i.e. ants turn into giant ants, giant scorpions, etc.) because exposure to the old magic is bringing them closer genetically to what their ancestors were like.
None of the player characters from any of the games are in any way related to one another.They're just five random yet extraordinary people called on to do extraordinary things. They're not related by blood, they aren't reincarnations, and with the exception of the Dragonborn and the Champion of Cyrodiil, none of them ever met each other.
The Elder Scrolls is a precursor to the events of the Legend of ZeldaTwo fantasy settings with all sorts of diverse/cool kingdoms and locations to travel in, and interesting characters and enemies to interact with; how can that simply be a coincidence? I'm putting this here just because.
There is no central hero in any central game.The grand achievements of each game (becoming Arch-Mage, the Madgod, Dragonborn etc.) are completed by at least two different individuals in each time of turmoil. Every time one of these occurs (that is, every major game so far), a warp similar to that which occured in the course of Daggerfall happens, as fate reorganises events to depict these grand achievements as the actions of a single individual. Sheogorath is an unlucky special case: being a Daedric Prince, and thus immortal, has left him even more confused before, as he reconciles his memories with the retconned reality.
TES 6 will have a title that's next in an alphabetical sequence.Could be just a wild crackpot guess, but seeing as we have Arena, Daggerfall, Morrowind, Oblivion and Skyrim, the next game could possibly start with a letter that's after S.
A future game will take place in ArgoniaAnd will allow the player to support the continued independence of the argonian nation from the Empire, as Skyrim allowed the player to fight for Skyriim's independence.
Dragons will still be around for TES VIThe next game wont take place too long after the events of skyrim, so dragons can still be found as boss like enemies which appear very rarely. the dragonborn didn't absorb the souls of EVERY dragon.
Jyggalag created HaskillHaskill appears to be a male Breton, only he's been alive at least since the time of Jyggalag's reign(why he didn't outright tell you about the details of the Greymarch... we can understand Sheogorath being a massive troll, it's how he is, but Haskill kept quiet...) and is mentioned to still be around in Skyrim's time. He knows how Jyggalag thinks and behaves and despite the realm of Sheogorath being wipe dout in every Greymarch, Haskill oddly survives the destruction. Either Jyggalag took a human and made him immortal, or Haskill is a daedric entity- perhaps a daedra given human form, or a fragmented piece of Jyggalag himself. Haskill acts in a calm and proper manner, unlike the rest of the Shivering Isles. He hates Jyggalag but that doesn't mean he didn't once work for him.
The Thalmor will be defeated by the time of the next TES gameBy the argonians.
Most or all the player characters are created by the elder scrolls themselves, or are an entity variant of them.The hero is never definite and at some times seems to simply vanish from reality, or should the achievements be written down or remembered quite literally change between sources. Now what does this remind you of? The thing the entire series was named after. Seriously. Plus, the Dovahkiin from Skyrim reads two different Elder Scrolls (possibly more if you try to read them outside a plot force), and doesn't go blind beyond a stagger, though this may be because player characters and dragon souls make for skipping the adverse effects. Plus, even the more hostile or randomly deadly princes never instant-kill the PC unless they're quite literally asking for it (ex. attempting to kill Sheogorath during the Shivering Isles), no matter how much Sheogorath wants to rip out your entrails, he suspiciously refrains from doing so. Presumably being a prophetic scroll thingy in man, mer, or beast form, they want you as opposed to shredding you.
The daedric princes are mostly bitter enemies by now.Well, imagine someone completes all the daedric quests and major questlines. Obviously, hero has pledged his soul to waaaay too many factions to sort it out fast. Barring Sheogorath's order-by-Jygallag nature manifesting early (pre-Shivering Isles) or Jygallag constructing a nice even timetable for everyone to share the toy (post-Shivering Isles), everyone has probably been arguing like mad over who gets the thing. In rare cases, the hero had enough filled soulgems to pay off everybody and go where he wants, but really, someone must have been low on extra souls and caused an argument. And these are the embodiments of concepts, some of which are less than friendly and conductive to calm diplomacy.
AlternativelyEvery single time a hero pledges his/her soul to more than one party, he or she just goes and gets some filled soulgems and pays them off and instead goes wherever he or she wants. The Dragonborn can pull a higher-value version using dragon and dragonborn (as of Miraak dying) souls. Presumably the daedra are fairly lax about this, considering that the few times it happened the champion in question either became immortal, Sheogorath, already had Azura's claim from the beginning, has Akatosh's claim and is ordered to Sovngarde regardless of race, etc.
There are racial afterlives for everyone.So yes, there IS a Khajiti Sovngarde-equivalent somewhere. Orcs probably just get sent to somewhere run by Malacath, so there may be an actual settlement on Ashpit's 'backbone'. The Dunmer probably have an afterlife run between Boethiah, Azura, and Mephala, possibly more daedra. Argonians are reincarnated via Hist, and if a major population change occurs more souls will be created for an increase and stored possibly on what remains of the Plane of the Hist, possibly the Um-Hist, or just in the same Hist providing said souls.
Jygallag's duties have been mostly spread between other Princes during his curse, and he's having to trudge through Oblivion trying to get them back.Peryite and Hermaeus Mora got the most out of it. Peryite got some of the duties related to order, and so used pestilence to make it happen. Herma-Mora got Jygallag's library (Apparently Sheogorath watches MLP and used teleportation fire to send the library to Apocrypha, or the 'burning' was faked and the library entered Apocrypha through the waters of Oblivion intact) because what better for the prince of knowledge and fate than a library that effectively IS fate? Hermaeus Mora also probably has an organization system for his library, but it is extremely arcane, eldritch, and generally bizarre and ordered more on a basis of land formations, sub-planes, and islands than an ordered library of shelves. Sheogorath-form Jygallag got/kept many of the realm's duties, but probably neglected almost all of them beyond "Don't dump the realm into the void, please.", even terraforming the Shivering Isles to some extent (I can't imagine the line-form-order Jygallag standing for such chaotic architecture. The islands either resembled a big square or a normal brain. Presumably the cities and such were added between Greymarches.) et cetera. Some of the other duties and powers may have went elsewhere (The Soul Cairn and/or Azura probably have a standing deal over whatever Hearts of Order are or similar), but most remained Sheogorath's and were accordingly neglected.
The Adoring Fan can cast Auto-LifeHe just happens to possess a much weaker version of the ability than most portrayals. He happens to know exactly how annoying he is, and so casts Auto-Life on himself before meeting with the Grand Champion, just in case s/he should turn on him. After a few days (due to the weakness of the spell) he revives, recasts it just in case, and picks himself up to go and search for the Grand Champion again, just because he's that determined to be of some help. Perhaps that's also how he manages to survive being left on a snowy mountain top for weeks because the Champion just wants him to go away. The reason he never brings it up is so that no one can cast Dispel and then kill him, and the reason he never casts it on the Champion is because he sees him/her as being so flawless, he'd never imagine them falling in combat.
Azura plans to integrate herself into Mundus without losing any powerThis is only to further another one of her plans, but hey. She seems to be doing lots of things that you'd expect the aedra to be doing, and even her portfolio (dawn and dusk) seems something naturally expected in the earthlike mundus as a baseline fabric of reality, unlike things that are less than naturally part of the world (Such as Clavicus Vile's portfolio), etc.
Azura hates Dunmer race and Morrowind.She became jealous when she saw Tribunal manipulating the Heart to become a godlike creatures. She tried to curse the entire race, but they became a successfull nation led by Tribunal instead of dying in fear and despair. Azura still needed to take revenge, so she manipulated Nevevarine to destroy the Heart. That led to destruction of Morrowind province, Dunmer genocide and Tribunal's final disappearance. Nerevarine then became unuseful, but too powerful, and Azura got rid of him.
The Ideal Masters are the result of Black-Soul Gems on Black-Souled Daedra like Dremora.Daedra are eternal; but their power can be redestributed. (Just ask Clavicus Vile.) When a Dremora's soul is captured; it's animus and properties do go to the black soul gem; and their "daedric status" is transferred to the black soul gem itself. When said Black Soul Gem is used up; the gem "died" on Mundus; but like all Daedra when "killed" it gets sent to a plane of Oblivion; in this case the Soul Cairn as living Black Soul Gems. Multiple daedric soul gems congregate and become the large floating Crystals known as Ideal Masters. This is why there are no Dremora ghosts in the Soul Cairn; and this is why the Ideal Masters are relatively "new"; it took a while since Mannimarco's ascension for Necromancer's to trap enough Dremora souls. (Even then, they usually focus on weaker humans; a lot of their creation can be credited to heroes like the Hero of Kvatch, or the Dragonborn.)
Both Azura and Hermaeus Mora will be "corrupted" in later games.Azura's by the shattering and possessing of her Star; increased by a magnitude if the Black Star is canon. She will be more influenced by the Necromancers and the Ideal Masters. Hermaeus Mora's change will be trickier. The secrets he absorbed from the Skall were "how to talk to the wind, how to listen to the earth." Mora is the Lord of Things Man Was Not Meant to Know....what happens when it learns things man should know? Mora will start to be driven sane by the revelation.
Jyggalag will play a big role in a future game or DLC.Jyggalag was so powerful that the other Daedric Lords put a curse on him, and at the end of Shivering Isles the curse is broken and he is free to roam Oblivion. Chances are he'll regain that power and will probably cause trouble in the Mortal Realm, most likely being the main antagonist of a future Elder Scrolls game or DLC.
Hermaeus Mora is an aspect of the Aka-Tusk oversoul along with Auri-El, Alduin and AkatoshXarxes was Auri-El's scribe, yet he's also Hermaeus Mora's scribe. Time and fate is part of Hermaeus Mora's domain, just like a certain dragon. In addition, he has an exceptionally keen interest in dragonborns, which as we all know, have the souls of dragons, which are part of Akatosh.
Hermaeus Mora is impersonating Shor/Lorkhan who is infact Alduin God of Destruction and Chaos.Evidence: 1:One of Hermaeus Mora's tomes was found in a chest supposedly holding the Heart of Lorkhan(which in Morrowind is destroyed). 2:Hermaeus Mora claims whenever you refuse service to him that you were already his pawn. 3:Alduin is mentioned in an obscure text to have corrupted and banished Mehrunes Dagon while Mankar Camoran claims that Lorkhan did it so for both to be true than Lorkhan and Alduin must be one and the same and yet.... 4:Lorkhan/Shor ordered his champions to help kill Alduin..... Or did he?..... 5:'mien is too bright for mortal eyes' which shows that the Shor who ordered Shor's Champions to kill Alduin is too bright for one to see his form so obviously they wouldn't know if they were looking at Hermaeus Mora. This would mean that Lorkhan/Shor is the Big Bad and that Hermaeus Mora is the Big Good who helped save the world without us knowing it!
A later game will have Jyggalag, Sheogorath and Hermaeus Mora helping you fight Alduin and Mehrunes Dagon at once!Jyggalag seemed to be on good terms with the new Sheogorath who's an enemy of Mehrunes Dagon who was corrupted by Alduin and considering the evidence for the above WMG Hermaeus Mora is Alduin's archnemesis and thus would be present for the big showdown between them.
Mehrunes Dagon was killed sometime after ES IV: Shivering IslesThe Hero of Kvatch AKA Divine Crusader, by the end of ES IV, has killed TWO mortals-turned-daedra with their own realms, and wrested control of an entire plane of Oblivion from a daedric prince. What those three instances provided was a nice learning curve and experience in defeating "immortal" daedra.
