I did a lore about all of this and how it was related to the Mythology World, and I'm glad I could finally find someone who agrees! I've came up with a whole lot of different solutions to the Destiny background, but they never made as much sense as the myth lore. I think that definitely Destiny has a "Mythological" background, like the Fallen, they are thieves and liars, if you can connect that, their "patron" is the Norse god Loki. The Vex are robots, a god who creates robots is the Greek god Hephaestus. I've been going on and on about this crap, but I've gotten far, if we could talk about this and get behind it that would be fantastic
