"The island of Vvardenfell sunk into the sea."

Agreed. That's why the whole "Red Year" and the sinking of Vvardenfell didn't happen at all in my personal version of TES. Voryn thoughtfully made sure that the moon was brought down with minimal damage.

I realize my way of dealing such things doesn't do anything to help others with their own games, but I'll explain this here since this thread seems to be more about the "official canon vs personal canon".

The lack of Dagoth Intervention spell has never bothered me because in my way of looking at it, a new intervention spell does in fact exist in my personal Morrowind world. The way I worked it out is that the Temples are all still there, but they have gone back to ancestral worship rather than worshiping the Tribunal. So Almsivi Intervention is now Ancestral Intervention. To add to the feel that the Temples have changed, I've add some ash priests, either by leading them there or using the placeatpc command, to the Temple interiors. I've also added a mod that adds teleport-priests to each temple and at Ghostgate, which is good for players who don't want to use the Imperial Guild of Mages travel system, or for when I reach the point of my game's timeline when Imperial organizations are being shut down and pushed out. I simply use what is already there and imagine any changes that would be in effect.

Again, I realize that my way of doing things doesn't work for everyone. Quite a few people want things to actually change in the game itself rather than just imagining that "the Almsivi Intervention text changed to Ancestral Intervention". On in the case of your example, Dagoth Intervention. And there's nothing wrong with that. There's no right or wrong way to play Morrowind and for anyone who would prefer that such a spell exist, that's what the mod sub-forum is for. It never occurred to me to ever ask for or attempt to make such a mod because with the way I approach the game I've never had a need for it.

 

I like that idea, especially since it would add something to the game without adding yet another mod to the load list.

Just a gentle reminder of forum guidelines; please only use character accounts in role-play threads and use your OOC account for threads like this. The one exception is the occasional breaking of the fourth wall where a character makes a comment in a thread in character, as Gilvoth and Neloth occasionally do.
