Actually Eliminster survived and Manshoon was an upper ranking mage,

The trial of vivic was a role-play is done in the forums, it can't be called offical.

opps.

I wasn't the one who brought it up.
If we start to talk monkeytruth, I talk monkeytruth.

He might have been voicing his own theory for Vivics abduction by daedra not referencing a roleplay post.

He mentioned the Trial of Vivec and Vivec banishing Azura.
That's clearly from said Roleplay...

That's why I don't like CHIM always when it appears every topic complitly derails, because there is need to explain existence of inventory window.
Lessons of Viveck always striked me as something that trys to tell, "no real guy, I was really always born god, I mean did you read this weird [censored] I wrote, this really happend"

Considering it was a roleplay between dev's, official is exactly the word I would use to describe it.

I will never understand what CHIM fully means...

Yep I agree. Hell most of our lore isnt found ingame but due to the writings out of game from the Mr. MK. I say its official because if we say a group of devs that roleplayed the trial AND commited it to writing, it needs to be official or we can say a good 75% of lore isnt canon either.

Is anyone severely worried that Fyr may be in Dragonborn and the writers will ruin the best character they created? Cause I kind of am.

One of the things that made Divayth Fyr so interesting was his ambivalence towards the Main Character in Morrowind. He had a cure that basically killed everyone else who ever took it and wanted to watch as your character drank it. I would hate to see him suddenly care about people.

He had those artifacts and didn't care. He can walk the various planes of Oblivion and doesn't brag about it, or even really want people to know. He has the last living Dwemer literally in his basemant and doesn't care if you find out.

I just worry. He was cool because of vast understatement - like when Tom Bombadil put on the Ring of Power. I just hope they don't blow it.

If they do, I suppose I can always just pretend it didn't happen and go play Morrowind again.

Some time age I wrote something to explain CHIM a bit in detail, Ill copy/ paste:

CHIM is the point, a hidden message, of the 36 lessons of Vivec you find in Morrowind.
Its a state of ungradiation.

In the Aurbis the general trend is subgradiation, things tend to split up into smaller and more numerous things.
Such as Anu and Padomay into the Original Spirits, such as the Aldmer into all the elven species we see today.
It is a fundamental property, like entropy is in our universe.

Lorkhan saw this and rejected it and came up with a plan.
He tricked and coerced and convinced other Et'Ada to join him in a great project, the scope of which none could achieve alone.
Magnus was the architect.
When it became clear that the realisation of the project of Creation demanded great sacrifice some left for Aetherius, Magnus among them.
Some stayed and poured themselves wholly or partially into Creation in order to stabilise it.
To continue they needed to invent birth and death, they needed to become smaller and more numerous. They became the Earthbones that are the natural laws and the Ehlnofey that became every living thing (except the Hist).
So the pattern of subgradiation continued on Nirn.

Until Talos and Vivec and maybe those we dont know about that achieved CHIM or another form of apotheosis.
For that is the purpose of Creation, to be a stepping stone, a trampoline, for the parts to reach higher than each individual spirit could alone.

What is CHIM?
CHIM is an Ehlnofex word meaning starlight or royalty.
Achieving CHIM is anologous to achieving nirvana on our world except that it is more pro-active and involved.
CHIM is looking back all the way through all these steps of subgradiation, to the ever bigger, until the realisation that Anu and Padomay themselves are just the musings or dreams of an unsapient Godhead trying to make sense of itself.
Failing this, it keeps splitting into ever smaller fragments that examine and try to make sense of itself until finally the viewpoint jumps up again and a person like Talos or Vivec sees the Godhead.

CHIM is knowing you are an infinitesimally small part of the Godhead, knowing that everyone and everything around you is as well, yet at the same time having a great enough level of self-love and love for the other to keep your personality from dissolving in this deluge of realisation. Many on the road to CHIM fail this test of love and zero-sum out of existence.
CHIM is not only realising it is a dream, but a lucid dream. Because it is a dream, because everything is me, I have god-like powers over reality.

An entity reaching CHIM however is unlikely to use it large-scale to influence events.
As said, it is realising you are in a very real way everything.
If your left hand fights your right, youre not likely to cut any one of them off.

Here's my rundown of my experience of Divayth Fyr:

• He's one of the oldest, if not THE oldest Telvanni wizard you encounter on the MQ in Morrowind.
  
• Despite his age, he has a witty mind and a "don't-give-[bleep]" attitude towards the other, snooty Telvanni or towards custom. So despite being 4000 years of age, he has a very youthful, jovial character.
  
• This supposedly old man wears a full set of Daedric Armor, save for the helm. (http://www.uesp.net/wiki/File:MW-npc-Divayth_Fyr.jpg) Note - Daedric Armor in Morrowind was much heavier than it is now. It took a very high Strength attribute to be able to don this juggernaut plating. And ol' Fyr totes it when he's in his lab like it's nothing.
  
• He has the guts to work with victims of Corprus, the disease every other NPC calls a "death sentence" once you get it.
  
• Like some sort of Chuck Norris of the TES world, he can make children out of thin air.
  
• He doesn't mind if you steal his stuff. On the contrary, he rigged his home and Corprusarium to challenge thieves and adventurers for sport.

It's safe to say he's a badass. A smart badass who also happens to be a powerful wizard.

Thank you for providing information I was to lazy to come up with.
