That's pretty amazing. User made mods and lore enthusiasts certainly give non-canon a sense of legitimacy that I would typically give the cold shoulder. A shame that it will take so much time and manpower to put into fruition, as by the time their dream is realized, odds are TES6 will likely be in production, if not already released and most likely on a whole new engine.
Still crossing my fingers for Elsweyr.
Though based on the events of the war between the Septim Empire and the Aldmeri Dominion, I can see the next turn of events taking place in Hammerfall, as resistance and conflict are still ongoing there.
Sadly TES:Online looks like more of a distraction from the focal point of story and lore of the 4th Era. The Great War will see another climax, as we've already seen the treaty tread on thin ice in Skyrim.
