So in looking at the 3rd Era lore (where this should be ~1000 years before Skyrim), there's not a lot of time in between emporer deaths/crownings. I mean perhaps 3E 114 - 121 gives a 7 year stretch, but for an mmo to exist in a 7 year period only seems a bit constrained?
2nd Era, not 3rd. The 3rd one only lasted four hundred years.
Didn't see your edit, sorry.
