So Game Informer states TESO is set a Millennium before the events of Skyrim,

If we take this to literally mean about a thousand years, then that is ~300 years before the time of the Birth of Tiber Septim, and the start of the Daggerfall storyline.

There is a big empty space of a few hundred years here, which gives Zenimax Online a lot of freedom to work. Akavir also plays a large part in this area of history, incluiding the Empire being ruled by an a line of Potentates from Akavir, Morrowind being invaded by Akavir.


However two other possibilities are there.
1. Misinformation, perhaps they just mean long before the events of Skyrim without a specific length of time.
2. They could mean Millennium as an Era, with Skyim taking place near the start of the 4th Era, perhaps this would mean TESO would be at the start of the 3rd Era

Discuss.

They already said about 1000 years, as well as what's going on in the timeframe. There's no speculation to be done.

A thousand years before Skyrim is about the year 500 in the 2nd era, 300 years before the birth of Tiber Septim, 400 years before the 3rd era and 700 years before Daggerfall.

Indeed. The 1000 years actually seems quite deliberate and very well thought out. It puts us right in the chaos that followed the end of the Reman/Akaviri dynasty. There's basically a 400 year gap in the political history of Tamriel from the death of the last Potentate to the rise of the Tiber Septim, so the MMO is well placed.

yeps i did the math after i posted derp the big question I have is how will Molag Bal be a threat without retconning something hideous in to the timeline? At that stage there were no records of Daedric activity, and this is only a few centuries after Sotha Sil made his deal with the Daedra to prevent their meddling in Mundus.
Whilst 600 years may seem like a long time, to the tribunal and the Daedra it would be nothing, and the tribunal are still at the height of their power at this point.

Yeah, it was already said that ESO will be set in mid-2nd Era. So much happened at that time, they have endless possibilites to choose from.

Hmmm, I wonder would Paarthurnax be in this time frame? Considering how long he lives, I believe by this time he was teaching the thu'um. If this games expands all over Tamriel then I would assume Paarthurnax would be the one NPC from Skyrim that would have to be in it. Right?

Not really into to MMO's, mainly because my internet svcks, but I should have brand new ISP soon.. may try this since it comes out next year... I just hope this will not effect the single player games.

Sounds about right, though I personally rely more on the impreial library than uesp. http://www.imperial-library.info/content/second-era

Well hrm..by my math it puts us at 2E 501. And that area of time seems to be scarce so they have quite a bit of room to work with or have worked with.
