Odin, tainted go? Or shapeshifting phantom? (Possible Spoilers)

[Evane]

Urth was a prominent figure. In Norse mythology, she is the goddess of fate. I think by killing her, Odin was forever cursed. I had this idea that Odin was a failed or an early Allagan "hero-augmenting" experiment that escaped. That's why they sent their hero (Acheron or another successfully augmented one) to clean up the mess.
