I believe when Bethesda first announced they were having The Infernal City written, the article (which was soon removed) also suggested the two books would bridge Oblivion and the next TES game (Skyrim). It also suggested the next TES game would be 200 years after Oblivion, but this was some time ago. As you stated, Oblivion takes place 6 years after Morrowind, so who really knows. Although it's probably safe to say Skyrim will take place after The Infernal City.
Yeah. I just now realized it was 6 years. I really need to brush up on my lore. :facepalm:
I will say that just because Bethesda makes a statement doesn't mean that they have to abide by it. They're the creators of The Elder Scrolls, after all, so they have the main jurisdiction on what takes place when. So I wouldn't be surprised if they took back their previous statement and decided that Skyrim might take place before the events of
The Infernal City. I guess we'll just have to wait and see if the upcoming
Game Informer article has any info on when the game is taking place.
Also, I'm pretty sure Solitude is better than Winterhold.
Not for my
Dunmer Shadowmage.
Winterhold
A wealthy and influential county in Skyrim. It is heavily affected by Dunmer ways and ideas, being close to the border. It contains the Ysmir Collective, and the well known College of Winterhold. It is located in Northeastern Skyrim.
