So if Nirn is the combined body parts of the aedric gods is the lava that flows out of red mountain etc aedric blood? And assuming it is when it cools it creates ebony? If so is it pooled by vvardenfell's populace for an easy source of ebony?
I apologise for such noobish questions but I merely thought about this this morning.

Thanks for any replies.

Ebony, also known as god's blood, is the blood of Lorkhan hence why it's only found in the northern countries like High Rock, Skyrim and Morrowind.

So it's not lava? If the planet is a mash of the 8 divines bodies then why is everything so....normal? Surely something's could be easily compared to aedric body parts? Lava=blood grass mud etc skin or am I taking the planet being body parts to literally?

I'm not sure if it is lava but ebony is entirely different from obsidian (http://en.wikipedia.org/wiki/Obsidian) You're probably taking it to literal.
