TWK: Thou Art god
When Art made his vow to defend that pass, he was an overgrown kid. What complicates matters is the fact that when he actually undertook the defenses he was twenty years older, had the aid of a magic steed, and was a god. In fact, in all of his battles in the second book, after he came back from Skai, he was a god. That hardly seems fair. What had a god to fear in his contests with mere men? Death? He had already died and gone to Skai. What were the natural parameters of his powers as a god? Exclusive of the clearly supernatural powers he used when he broke his vow at the end of the story, how much stronger was he as a god than a mere man, and how much did that influence his prowess as a warrior?
When Overcyn Able bent his knee to Queen Idnn or King Arnthor, a Mythgarthr god was bowing to his supposed worshipers, a blasphemy of sorts, a reversal of the natural order of proper homage in the cosmology of TWK. I thought that was what got the Aelf in trouble.
And when Art the god stooped to dally with Disiri, he was twice removed from her, in terms of holiness. He was farther above Disiri near the end of the story than Michael or Parka was above him.
