Could the original 8 of the Nine Devinne be the Deadra Lord(s) of Tamerial. Tamerial is the realm of change, so could the lord change? Like in the year of Akotash, Akotash is the one in charge. It is just a thought I had.....

Think you misunderstand a good bit about Daedra and Aedra. I recommend you go read the boock "Aedra and Daedra" at TIL.

Also, Nirn, that is, the planet, could be considered the realm of STATIC change really. Not too sure Tamriel could have a "lord" at any point. Might also wanna read "The Monomyth." Good stuff in that one relevant to your question. I'm also pretty sure the FAQs in this forum could help tons, too.

That would be Lorkhan, at least if you believe Mankar Camoran. The very definitions of 'Aedra' and 'Daedra' make them mutually exclusive (though it should be noted that Mankar rejected the distinction anyway - to him, there were only Daedra).

I developed this idea some, after reading what Mankar had to say, and http://www.gamesas.com/bgsforums/index.php?showtopic=826220 on it.
