Something has really been bugging myself and my friends as we work through Skyrim, likely as a result of the idea of Sovngarde being central to the main quest (as well as the Companions). Over the course of the game, the Dovahkiin has the opportunity to follow all the Daedra, join the Companions (devoting himself to Hircine), join the Brotherhood (Sithis/Mephala), join the Guild (Nocturnal), and be a true Nord(Sovngarde)/true Orc (Malacath). Generally, when a patron of Daedra dies, they go to the realm of Oblivion belonging to their master. In Morrowind, the Nerevarine was a reinacarnated god (or else he fulfilled the prophecy of one), and therefore the point was moot. In Oblivion, the Champon becomes Sheogorath, so he's obviously in the Isles. In Skyrim... where do you go when you die?

If you worship multiple Daedra, as well as being a true Nord, do you go to a Daedric Realm? Do they cancel out and you go to Sovngarde? Does one Daedra over-ride the other? Are your personalities ripped apart to the various realms to which you were devoted (i.e. your ambition going to Mehrunes Dagon, your anger to Malacath, your Craftiness to Nocturnal, your primal instinct to Hircine, etc.).

Basically, what happens if you worship multiple Daedra?

This question has been asked dozens of times.

Where you go when you die depends on a few things:

First and foremost, if you're a werewolf, then you go to Hircine's Hunting Grounds. This seems to take priority over pretty much everything from what I know.
Secondly, if you swear your allegiance to a Daedric Prince, then you go to their realm. If you worship multiple Daedra, then it depends on whom your allegiance really lies with.
Third, if you die with courage and valor, and you are a True Nord at heart, then you go to Sovngarde.
Lastly, if you are otherwise unaffiliated, you go to the Dreamsleeve.

Also, Argonians go back to the Hist, but I don't know what priority that takes.

Big Eye was in the Isles, so it seems to at least be lower than Daedric allegiance.

Good point. Lower than Daedric allegiance, higher than Dreamsleeve. And I have my doubts that Argonians are ever really True Nords at heart, so I think that gives you a good idea at where returning to the Hist is as far as soul-priority goes.

If your strong enough you go where you want to go. The Dovakiin could give Hiricine the middle finger whilst strolling into sovngarde despite being a werewolf.

I think you go to the plane which you resembled most in life/death. If you lived and acted as a werewolf you'd go to the Hunting Grounds, if you died in battle like a true Nord Hero you'd go to Sovngarde et cetera.

When a similar question was asked, someone said that if the realm in question wanted the soul that much, they would start a sort of bidding war with the other realms or hold a court to try and settle an agreement, which I think is pretty cool.

That is pretty cool

I imagine there would be a lot of paperwork to be done, maybe the different parties will have a Magna-Ge check it to see who has priority.

that wasnt exactly the traditional way of entering sovngarde, still being alive and all that

I did mean post death.

Dovakhiin post-mortem is gonna be a huge friggin' ball of dragon souls. Principalities won't even dare to glance at 'em funny, much less try to enforce some punk oath THEY made 7 eras ago.

This strikes me as a decent idea for a mod. An event that happens on your character's death, wherein you travel through the realms of Nocturnal, Hircine, Sithis and Shor to decide where your soul will go when you die.

This is generally how I see it. On the off chance that the Dragonborn doesn't become Talos 2.1 and therefore renders the discussion moot, he would be so spiritually powerful both from his own ability and the dragon souls he forcibly stuck to his own that I'm pretty sure he could do as he pleased.

Did Big Head die and go to the Isles though? Oblivion doesn't take place that long after Morrowind; he could have simply found a way in much like the CoC, unless I'm forgetting something that explains how mortals are living in the Isles...

Well, on the subject of the Dovahkiin, his soul is mostly aligned with Aka(as a result of all the absorbed dragon souls), so his soul would go to him.

Actually Aka doesn't need souls as the Princes do, neither as his aspects do. True Nord warriors go to Sovngarde as a gift from Shor yet not Lorkhan, and I'm pretty sure Shezarr has a different perfect missing place for his Cyrod followers.

If Dragonborn would not become Talos v2.1, perhaps he would become an Aedroth, a man-bull snowwhale whose voice is from his mother who is Kyne.

That basically is Talos v2.1.

@Nihilee Ah. Yes, I misspoke. However, since DK's soul is mostly aligned with Aka, I have a niggling suspicion that he will just become a part of Time.

Talos is a facelet of Lorkhan whose prime role is Lorkhan's Love of Mundus, aka the very idea and passion leading to the Creation, which needs both Aka and Lorkhan, perhaps plus another Magnus to complete into being, and thus he succeeds in bounding Mundus into the hub of the Wheel.
Dragonborn is Talos v2.1 only when at the same time 1, this person is born a Shezarrine, 2, he mingles enough dragon souls as Tiber/Arctus did with Wulfharth's soul, or mingles the soul of Alduin, and 3, he succeeds in stopping the Thalmor's plot or whatever of dissolving the Mundus bound, which in progress may be one of the causes that Alduin appears. (And perhaps a 4, a Magnus-to-be who keeps on watching
We now have 1 and 2 it seems, yet we know nothing about the third.

On the other hand, to be an Aedroth is quite simpler than this. If you absorb enough dragon souls, you become an Aedroth-a dragon eventually.

Since we're talking about Talos for a moment, you point out that he is a (facet?) of Lorkhan/Shezzar/Shor, which reminds me of the other side of the enantiomorph. For Lorkhan there is Auriel, for Shor there is Alduin (even if this aspect is shed,) for Shezzar there is Akatosh. Talos becomes the fourth-facet of the Space god, who upholds convention. In Akavir, Tosh'Raka becomes a facet of Akatosh (we presume.) Now a new Dragonborn rises, which will not necessarily undergo a form of apotheosis, but may; if this is the case, I argue that it will not be a mantling of Shor or Talos v2.1, but a new, fourth-facet of the Time god, and that a similar development may be occurring simultaneously in Akavir. I know it's arguing shades of teal when we consider the space and time gods to be different sides of the same coin, but it strikes me as plausible, all the same.

If so, barring the deal with Molag Bal referenced in one of The Elk's more recent works, I don't think even the Ur-dra is going to have much of a grip on the Dragonborn's soul. In any event, Convention will (likely) be reinforced.

I'm no lore master but I'd like to think that with the Dragonborns soul being so big and powerful. (All those dragon souls) That he could move freely between the realms of those daedra that he made promises to.

Prob'ly. Both if he stays mortal or becomes a god, he can probably go chillin' wherever he wants. Especially considering that Kodlack considers "rescuing" the other harbingers from Hircine's realm as possible, and he is a regular human.
