Don't expect the game to be Lore friendly, I mean it's 1000 years in the past, yet Orcs are playable? Heck they had just incorporated to the Empire during the late third era.
Basically, looking at other past MMOs, I'm looking at you WoW, they will break, bend, make new Lore that makes no sense just to snag more players.
Orcs being playable isn't really a problem. If there's a point of contention about their inclusion, it's that their lumped with the Bretons and redguards, rather than say, the Nords.
Probably not, the area is just going to be the same as in Oblivion.
"Let me show you the power of Talos Stormcrown, born of the North, where my breath is long winter. I breathe now, in royalty, and reshape this land which is mine. I do this for you, Red Legions, for I love you."
Or for your ancestors who I never really met, but who must have been pretty cool as well..
Before the inauguration of the third era, everyone in Cyrodiil lived with the painful feeling that their entire land was utterly wrong. No one could explain this mass psychosis, and everyone, at every moment, felt as if they were just being struck by it. It never felt like a old condition. It was as if every individual second of existence, past, present and future, had been simultaneously attacked by some unknown force.
