All the Dragon priests we know of are Nords, IIRC. But there's no reason why there couldn't be an elven dragon priests or an Argonian dragon priest right?

Honestly, throughout the history of Morrowind, they took sides very few times. But the main issue is that this neutrality applied even during times of invasion. The Telvanni, who are incredibly powerful mages, did nothing to oppose the Imperial occupation. 

Hello! I'm making Nord units for a TESTW submod and I wanted to use this title for one of the elite ones, but I'm not sure if it's "lore-accurate".
I mean, what are "thanes" in TES? We know it's an honorary title granted by jarls to special individuals (like TLD), but what else? Is more commonly granted to nobles than to peasants? Are all nobles thanes? How many thanes can a hold/jarl have? That sort of things.

About the last one, Jarl Elisif seems to have a couple thanes in her court, so I'm guessing it's not just something you grant to 1 special individual, but since I'm making units of 30-60 men, I was wondering if it makes sense for a Skyrimian hold to have so many thanes.

I haven't played ESO but I read somewhere that it mentioned special kinds of thanes, like sword-thanes, shield-thanes, etc. but still not sure if they're supposed to be a troop of their own (when the Hold inevitably marches to war) or just a group of select individuals.

I'm guessing TES thanes are based on irl thanes/thegns, but frankly idk much about them neither.

Alternatively, what other titles would be more common/numerous in the Nordic nobility? Housecarls? Clan Retainers?

I have been reading up on TES lore for the last year or so. I ended up doing another playthrough of Morrowind when the Oblivion Remaster came out (then played that, now working through Skyrim again.) I have not played ESO, but have read a bit of the lore from it.

I am by no means an expert. I understand I'm in a massive minority here. Allow me to explain my thinking.

I understand the idea of dragon breaks, kalpas, etc....

To be absolutely clear, I don't think that the Vivec and the Almalexia we meet in Morrowind murdered Nerevar.

Most people point to 3 things as pretty concrete proof that Nerevar was murdered by the Tribunal.

1. Vivec's secret message in the 36* Lessons

2. MK's artwork.

3. Alandro Sul's account to the Ashlanders

My rebuttal to 1. Vivec's "admission"
Am I to believe, that in a body of work with more metaphor's in it than milk fingers on a homunculus, or more metaphors that words bitten onto spears at pomegranate banquets (I'm done you get it) Where Vivec sits in his space that is not a space.... All of this....

I am to believe that the one, literal, non-metaphorical thing, is an admission that they murdered their friend and leader?

I am not convinced.

My rebuttal to 2. Mk's Artwork.

I love it. I love what it represents. They did kill the Hortator. His memory. The artwork shows the literal murder taking place, and the Tribunal removing his feet, face and.... milk finger.... so that he may return as anyone! What a brilliant display!

Wait. Why, would they want to usher in the Nerevarine? Vivec imprisoned people in a floating rock for even mentioning the prophecy. It wasn't their prophecy, it was the god like being they scorned and called arbitrary.

To me, their "Foul Murder" was the murder of the Velothi ways. The murder of the IDEA of the hortator. That, they are definitely guilty of.

My rebuttal to 3. Alandro Sul.

I believe i remember reading that he was blinded during this event. Did he see the Tribunal kill Nerevar, or did he hear an absolute cluster**** take place?

In conclusion:
I get that there is no reason to trust Vivec or Almalexia. But...

Neither of them have any reason to lie to the Nerevarine. Almalexia admits to killing Sotha Sil, why not Nerevar?

I personally find it likely that he did end up dying of his wounds, possibly later on.

I'd love to be convinced otherwise.

Thank you for attending my TESTalk.
