Maybe this might help:

Ah, thanks. Interesting, but I don't "count" forum posts as canonical, regardless of who made them.
Just a recap on my favourite ideas so far:
Arcimaestro:
if you refuse, she'll get crazy and will scream something like "you want to keep its power for yourself! Hands! Kill him before he wears the ring!"
Then the doors of the High Chapel would be sealed, and the only chance to survive is to wear the ring, so you may travel to Sotha Sil and meet the god. (waht will follow, we'll see)
Helena
- motivation to work for Helseth?
- motivation to create ashstorms?
Alaisiagae
- Perhaps, while some NPCs keep hinting that it is a bad idea, you can have some of the Temple NPCs reassure the player that the Band isn't evil, it is just a tool to be used (for good or ill).
- Nerevar connection?
- Perhaps some new dialog could have her explain what she wants the ring for (well, not her real plan, of course). She could say she caught wind that Dagon is planning to invade Tamriel, and she needs it to thwart some of his minions/sleeper agents. The Band can supposedly allow the wearer to travel across all sorts of realms - perhaps even into Oblivion.
(So the idea that is forming is that she first of all lies and says that you need to turn on the ashstorm machine thingy to prevent some terrible ill, and then blames Sotha Sil and says that she needs the Mazed Band to stop Sotha, who has gone crazy.)
jackfrost:
- you need sotha sil to shut down the Dwemer climate changer
(... or to stop him wreaking further havoc)
[Jac: pls add global]
Alaisiagae:
The simple thing would be to have Barenziah maybe advise the player to play along with Almalexia's game, to see what she (Ayem) is up to.
... Then she could be all like "Oh noes! Sotha Sil tricked me, he's gone crazy from losing power to the heart and wants to steal the power from Vehk and me, he's sending Fabricants via the Band!"
Miriele:
Yes, this. Personally, I was also disappointed that I couldn't go to Vivec with any of this, even after it became obvious that Almalexia was losing it. You're on speaking terms with the guy, and it seems like something he might want to know (even if he'd probably just send you back on the theory that you can handle it yourself).
Agreed. Vivec needs some dialogue - but, like Berry, he could simply advise the player to play along and find some evidence.
