[Elder Scrolls] So what's Oblivion like? Actual Oblivion as in the space between realms I mean.

Is it like 40K's Warp, or legit outer space?

It is impossible for a mortal mind to comprehend.

You can actually see it, you know? look at the sky at a clear night, and you see "stars".  
This isn't actually stars, but holes in our plane of oblivion. Yes, Nirn is a plane of oblivion like the others.  
Significantly less on fire than most, though, i quite like it here.

The sun, like the stars, are also a hole in our plane of oblivion, made when the god of Magic, Magnus, left our plane of existence after making it.. It is much bigger, though, which explains why it hurts to look at it.  

So, more like WH40k warp, but less crowded.
