Did Dagoth have a plan enslave or exterminate other races? Would corpus become a pandemic?
If Dagoth conquered Imperial City and killed the emperor, Dagon would still be able to invade Tamriel and with no one to help Martin relight the fires, would Dagon be more powerful than Dagoth?
Also, Thalmor would probably never rise to power.
I admit I have only slightly above average knowledge of TES lore, so maybe I'm not taking some important factors into consideration.
Anyway, I'd just like to hear your thoughts on the matter. What would Tamriel be like if Dagoth won?
