What do you think would have happened? How would he have handled Dagoth Ur or Numidium? Would he have been a wise ruler? (he managed the kingdom for ten years)

Awwwwwwwwww Crap, I meant for this in the Lore Forum

Saying he "managed" the kingdom is a bit of stretch. Wars broke out everywhere and the Empire started to fall apart. I'm also quite certain that he would never have sent the Nerevarine over to Vvardenfell, so Dagoth Ur would never have been defeated, Akulakhan would have been completed, and Dagoth Ur and his new God would have probably ran Jagar Tharn over along with the rest of the Empire.

If it got that far, that is. I'm not as familiar with the Daggerfall storyline as I am with Morrowind's, so I'm not fully aware of the repercussions from the real Emperor being gone.

Although wars broke out everywhere etc., most/some of that could be attributed to him focusing most of his resources on the Eternal Champion.

And Tharn was a master of disguise and deception, if he could fool the Council into thinking he was Uriel, whos to say he couldn't have pulled the wool over the Ashlanders eyes?

The same reason the Tribunal couldn't? but most likely because I don't think the Ashlanders would have given too craps about what was happening in the Empire or who ruled it, its not like the Empire could really enforce their rule on them. As for Tharn, he had been in power for years, and it didn't take years for the Eternal Champion to free Uriel. I'd have to agree 100% Velorien on this one, Tharn was by no means a management tycoon, and I would probably attribute the Empires decay to the power being in the Elder Councils power, rather than Tharn. It really didn't seem he cared much about the Empire, rather than the cushy life and prestige that came with being 'Emperor'.
