Azura cursed the Tribunal the instant they tapped into the heart of Lorkhan.
Vivec also bastardizes her at his http://www.imperial-library.info/content/trial-vivec
If what Vivec says is true then she cursed the Tribunal and plotted their suffering under the guise of helping the Dunmer people.
I just read the Trial and it is kinda scary. AlmSiVi really lives after all? Once a god always a god? How is Azura banished? Bound to this world and then destroyed? If she really is a deadroth and not herself a usurper then she can't really die forever , it just might take her a while to come back. Might she come back as a different Lord of Oblivion?
I am aware it is only semi-official but still raises some questions and it is a freaking good read full of symbolism.
Did vivec achieve CHIM?
Might explain some of the questions of why Vvanderfell is destroyed after Azura sent the Nevevarine "to save the people of Morrowind" . Since she is not present any longer (or not able to function very well) and the people have stopped loving Vivec then there is noone to stop the Ministry of Truth falling on Vivec City.
Which begs the question. Will she make an appearance at all in the next games?
