Having read this document several times, I never really attached much importance to the fight it mentions, between the Tribunal and Dagoth Ur: it seemed to consist in relatively small skirmishes, opposing three living gods against another deity and his seven brothers (the Ash Vampires). But delving further in the few texts and dialogues concerning this war, I've come to think that the conflict proved to be a real full-scale war, instead of small raids, though all of this remains a theory.
There is a mention of "annual raids against Dagoth Ur" made by the Tribunes with the help of Ordinators and Buoyant Armigers, but their numbers are unknown. Vivec also speaks of the retreat of the "surviving Buoyant Armiger", during their last campaign (led in 4 E 417). This could imply the use of important armies inside the ghostfence, and perhaps a series of sieges against the ash vampires' citadels, rather than a tactic of small raids.
So, here is my first question: how large do you think the war between the Tribunes and Dagoth Ur was? Was it a succession of minor raids for more than 400 years, or a series of large battles and sieges?
I would also like to know if this war could have affected the whole politics of Morrowind, including its relations with the rising Empire (For example, in the PGE 3rd edition, it is said, about the peace between Tiber Septim and Vivec, that "Septim, not eager to fight three Living Gods and also worried about Dagoth Ur's return, agreed to a treaty").
Hoping that my English is not too catastrophic and this post not too boring.
