I'm playing a round of Oblivion and this just occurred to me: In order to open the portal to reclaim the Amulet of Kings, Martin needed the blood of a divine. Well, most of us know where the blood of the divine was found.
Since Martin's solution worked, I should think it would settle once and for all the divinity question regarding Talos.
I am sure that others have already thought of this, discussed this, etc., but I had to post it.
