So far we've had the Monomyth and Faith in the Empire describing all religions as different versions of the same story. Be it with some actors missing in some, some stranger ones in others. Akatosh, Alduin, Auri-El. They hold the same position in each phanteon. Gods of time. Different visions of the same set of concepts.
If Alduin and Akatosh ever talk about each other they should talk about them in terms of mirror images. That god, that is like me, but is not like me. Where they recognize their own thoughts, yet see themselves as alien. Yet Alduin in Skryim is just a Dragon. With a Dragon mommy and a Dragon daddy and little Dragon brothers and sisters. It's a completely different vision.
Now I'm borrowing terms from Shor Son of Shor, but the underlying concept, a world where gods are different cultural variations on a theme, as presented in the Monomyth and Faith in the Empire does not fit with the idea that Akatosh would sire Alduin. Had it rather then Akatosh been Anui-el, Fadomai, Nir, all names not present in the Nordic mythology, it would have made more sense. They've all been giving birth to gods.
If all religions are different variations on the same story then perhaps we're laying witness to the Dov's variant on the monomyth. Think of it this way, the Khajiiti pantheon likens the gods to kittens and littermates and whatnot. The Dov's perspective on this event could be even more abstract when translated into the common tongues of man, a bit like say, the Tsaesci perspective. Alduin is the son of Akatosh because he is the inheritor of an aspect of him perhaps. Paternal relationships could be to the Dov as say "eating" is to our Tsaesci friends; perhaps even the opposite. :wink_smile:
Also we haven't quite accurately questioned the fact of what precisely it's like to be Alduin laying witness to his species's variation on said monomyth.
If he is "Aka son of Aka" then have we met a mythical storyline equivalent in Tsun? (That is to say purely from the writers perspective, is Tsun the shield-thane of Shor implemented as a gigantic foil to Alduin?) Something that also made me think is why he didn't participate in the fight with Alduin...
Also if Aka and Shor are the Rebel-King pair of self-same twins on each end of the umbilical cord then is it relevant which one our Dragonborn is more representative of?
I think other games had these relationships implemented in a fashion less central to the plot, and over time we've all drawn up our ideas on how these things fit together, and perhaps my long awaited chat with Alduin has come out just a bit different than perhaps we all expected.
