In a world where humankind is the weakest and least
effective form of life, the gods (Wotan; Fricka, his wife,
goddess of family and hearth; Donner, god of storm;
Froh, god of light; Loge, god of fire; and Freia, goddess
of eternal life) rule proudly - although they are neither
the oldest nor the most potent forces or beings in their
sphere. However, their power is precarious: It depends
on their ability to compel submission from two magical
and creative races, the giants (builders of large things)
and the dwarves (builders of small things), both of which
aspire to supplant the gods.
Okay, so we know that Morn and Angus are Siegmund and Sieglinde, and the Amnion are the dwarves.
When characters like Warden Dios, Min Donner,
Godsen Frik, and Hashi Lebwohl take the stage,
they come, as one might say, "trailing clouds of
glory" - the ether of their Wagnerian avatars.
I will admit right now that I am by no means a Wagner expert, and most of my 'research' is from the same place as the above quotes; the 'ancillary documentation' in the afterward of The Real Story.
So which Wagnerian avatars best represent the dramatis personae of the Gap Cycle?
Warden Dios is obviously Wotan; he traded his eye for insight and wisdom, and it's said that from his watchtower he could look out over the entire world and see at a glance everything that was happening.
Min Donner is likely Donner, god of storms, but I see her more as Brunnhilde:
Broken-hearted - and aware of his own doom -
Wotan commands his favorite Valkyrie, Brunnhilde, to
make sure Siegmunde and Sieglinde are killed by
Hunding, Sieglinde's rapist/husband.
As Wotan's favorite, she thinks of herself as his will
incarnate.
(His 'executioner'?)
Holt Fasner is probably Fafner, a giant who built Valhalla and could turn into a dragon.
Valhalla = The UMCP? The GCES? Both?
Hunding = Nick?
Hashi Lebwohl = Loge/Loki?
Godsen Frik = Fricka? (Implied by his name, but 'goddess of family and hearth'?)
Norna Fasner's name probably comes from the Norns; goddess of fate who were frequently consulted by the gods.
"According to some mythologists, their mission was to warn the gods of future evil, to bid them to make good use of the present, and to teach them wholesome lessons from the past."
Davies must be Sinfjotli, as he is the son of Siegmund and Sieglinde, though I don't know much about Sinfjotli, or if there are any parallels between him and Davies.
I think more research is required. Feel free to jump in with corrections or additional ideas.
