Shor is to Lorkhan as Alduin is to Akatosh? They are both their own father, regardless.
Possibly.
I've been seeing some dicussion lately of the different cultures' pantheons, which imply that the different names for deities that are presumed to be identical with one divine in the Cyrodiilic pantheon, are somehow distinct entities.
Partly under the influence of a science fiction novel I read recently, I've been thinking that the nature of language is part of the story. That is, in the language of dragons, in which there is no distinction between debating and fighting, there is little or no distinction between signifier and signified. Mortal languages are subgradient to the language of dragons. Perhaps both are subgradient to Ehlnofex.
Getting back to the divines, perhaps by referring to the same being by two names, and telling somewhat different stories about that being under each name, would create a fracture in the identity of that being. And I think that might mean that the Imperial Cult is more important than we realized. And remember Tiber Septim's Temple of the One?
What happens if the Earthbones crack?
