I thought it would be really cool if Dagoth Ur had went on Nerevar's side if Nerevar tried to persuade Dagoth Ur to rejoining his old organization. For Sotha Sil's loss, he could actually restrengthen the Tribunal to an actual three including Nerevar of course. Dagoth Ur giving up his purposes? To have all his lieutenants who could be solid members of the Tribunal? This would be good for Morrowind as a nation. Having yet another major personnel would've been great.
First explain why that wouldn't be as improbable as Satan eating hamburgers with God at a company picnic.
being a christian I honestly must say thats the most interesting mental picture I have had all day...makes me wonder if mormons also saw jesus playing keep away from statan considering they believe they are brothers....though that also begs the question who is older...meh
anyway, if we look at all the facts, the tribunal is a lost cause from day one and no matter who you stick on it, it was destined to fail. Vivec may have learned the error of his ways but he still commited the error i the first place and was never actually punished for it so its still there...sotha sil was an isolationist who loved his alone time. Almalexia was driven mad by the power so mad in fact that tormented th people she 'loved' with an ashstorm. Not to mention the three of them banded together and killed Nerevar thus proving how absolute power corrupts absolutly.
Just being in the presence of the Heart made Ur more and more insane by the moment I mean did anyone actually cacth the fact He himself was building a giant metal god with which he would destroy all of nirn.
All that said. Sticking Nerevar in Vivec's place would most likely result in the Creation of a mad god whom would have the united forces of the great houses and the ashlander tribes.
Logically, Red Mountain would still stand and so would the construction of Akulakhan. So Logically... The construction would rapidly speed up, the resources would exponetially increase, An army would rise up from the province of Morrowind and the power of the Tribunal would push out all Imperial presence. The temple's Doctorines would be rewriten. The dwemer devices such as the weather witch would be utilized as tools of war and be used against the Empire to destroy supplies, kill or hinder forces, Slow any advances against Morrowind, Buy enough time for the completion of Akulakhan and Pretty much all Outlanders and Nondunmer would be exterminted by ethnic cleansing parties. The great Houses would be restored, the ashlanders would join the fray because Nerevar being their Warlord would call upon them, and the Chimer would rise up and consume all of Tamriel. Most likely they would strike their neighbors of Skyrim and Black Marsh whilst bolstering their defenses at the borders of Morrowind and Cyrodiil.
It wouldn't take much for the God-kings to keep such a small section defended against a single nation what with the treacherous bitter colds of Skyrim and the Perillous and terrible swamps of Black Marsh truely the only real ways in for the Empire. So the Chimer forces would begin laying siege on the lands surrounding Cryodiil thus blocking them off from all help. And finally once they are completely surrounded, Their once Vast empire now under the thumb of the Tribunal would come crashing down upon Cryodiil... Most likely the Chimer would enslave all the other races and use them as soldiers against The imperials, thus rendering the Imperial race extinct, and thus they would cleanse The Nord's next because they are the closest human threat, then the Redguard, the the bretons, then the Argonians, finally the Khajiit, and then the Orcs, wood elves next, and finally the Altmer...
Thats when they would branch out and consume all of Nirn...
so now that I have outlined every little detail in why the Tribunal is a bad bad bad thing in any shape or form or compilation or whatever you would like to call it.
pretty much...if Almalexia and Dagoth Ur are allowed to work together combined with the resources and backing of Nerevar...we have an apocalypse...
Nerevar is the Tiber Septim of Morrowind. Dagoth Ur is the Devil of Morrowind. And Almalexia is the Harley Quin of Morrowind. mix the three togther and the rule of thumb comes into play.
absolute power corrupts absolutly.
