Recorded info, observations, and the occasional parallel to reality.

This is MK you are dealing with.

The common bonds between myth shed light on the truth which they were made to describe. A lone myth cannot be verified. It may be true, it may be a story; we can't truly say. But let's step away from myth for second. Consider this?three people are accused of stealing a cookie from a cookie jar. No one observed them, and you have only their stories to go on. Naturally, each story will be skewed, a combination of truth with lies born from the individuals tendencies. Pick out the common truths, and you can form a much better idea of who might have done it; pick out the lies, and you can see the diverging individuals. You may not know the absolute truth, but you can form a fairly good idea of it. The myths of the ES series work in much the same way. Still, if it settles anything, it's all basically summed up in http://www.imperial-library.info/mwbooks/monomyth.shtml. Tear from the weave its common threads, which are truth.

Also, remember that this is a game. The Devs aren't going to spend years making lore, and then suddenly go, "Oh, wait, just kidding. It was just a big simulation by some guys named Patty May and Andrew who got in a fight over their girlfriend, and who everyone keeps calling Padomay and Anu for some reason? And Vivec? Just some crazy guy who learned how to use the console to edit his stats via the "chim" password?" They may try to conceal the truth, but the truth remains. It's in the documents and the accounts, left to us so that we might aspire towards understanding (reject the contradictions of creation, but even then, Akatosh, Lorkhan, and Nirn remain, which is the main point). The worst they may do is make multiple "truths," leaving it to the player to decide which to accept (Goodall seemed to hint at as much in http://www.uesp.net/wiki/General:Douglas_Goodall_Interview interview). Pure Meaning by Impure Words. That is the method, truth within lies within ambivalence.

Basically, in short, we can't truly observe Mundus. We see only what we are meant to see. The rest we must discern from the lore given to us via books and letters. It may not all be true, but I think we're safe in assuming they aren't just churning it out so as to laugh at our attempt to solve it (Well, maybe, but I at least mean it isn't all false.) I have the odd feeling that I wandered terribly off track there. But yes, the common threads of a story usually hint at a truth, be it myth or differing accounts of who stole a cookie out of the cookie jar (and really, the myths of the ES series tend to more like the latter).

The Missing God hates himself? Interesting dichotomy. Then again god are not mortals.

Divine Angst!

You just had to say it didn't you? hehehe
