When Alduin goes about devouring the souls of the dead from Sovngarde and all that, would he also be able to reach those trapped by the Ideal Masters? Or would they be forever screwed over by there horrible luck and terrible life choices?

When Alduin eats a soul they seace to exist. I'd say the Soul Cairn is preferable. At least there are ways to be summoned back into Mundus.

Alduin can eventually enter every realm, for when he eats the kalpa, that includes Oblivion. Currently, I doubt he can enter the SC.

Well, Sovngarde isn't in Oblivion, as far as current understandings of the universe structure dictates.

I was referring to the Soul Cairn, which is a minor Oblivion realm. I think Sovengarde is in Aetherious.

Interesting... I wonder how much of a fight the Ideal Master would put up to keep him from devouring their cattle... I'd watch that.

I was stating that in response to the TC, but I am apt to agree, that it exists in Aetherious.

And wasn't that large...body in the sky the dreamsleeve?

Must see pics.

At the end of time? They wouldn't be able to put up a fight at all. He'd just eat them and the Cairn in one bite. If you mean before he begins eating stuff, I have no idea.
