A symbol that guides someone on a path of faith. Without faith you become a scientologist...
But, pushing away your 'theory' (in all it's irrelevancy) I don't think the Triune were worthy of the title given to them by the Dunmer. It was in fact their "gods" that made them that way. I can't remember where I read it, but it was Sotha Sil who spoke against Azura, who reacted by changing the Chimer into ash-colored Dunmer. Sotha Sil said the daedra were growing weak. It's the aedra that create things, the daedra can only manipulate these things. Maybe the Chimer were oblivious...
