Funny, those are the biggest points of intrigue for me. Well, elven lore surrounding the gods anyway.
The book wasn't about elves, the main characters just happened to be elven. The book's about the Griffons, and how awesome they were, as well as why they were "extinct".
It's also partially about blood magic and the taint, suggesting there's a link there.
I was bored by the temple of Mythal part in "What Pride had Wrought" (but fighting side by side with Ser Barris against was ****** awesome), those "gods" bores me to death.
And the protagonists being elves already make me dislike then, elves are a worthless race in any game be it in Warcraft (destroyed the Horde), Magic the Gathering (Goblins > Elves), Witcher (Order Path + Roche ftw), etc. Dont remember liking a elf in any kind of game, the elves of DA are no excpetions.
I hate the Grey Wardens, wish I could disband them and every nation make their own tainted soldiers to fight agains then
But I will give you that Griffons are cool.
