I like mythology that makes itself. Often it's crap, but often, it's fun! Take good old Link and his Triforce now! It all makes sense, Gannon is just Gengas Khan and his Mongol Hordes!
What's better for a mythology starter then Action Comics #1's Superman? Not much else, and you can read it for free online.
Also, here's a picture of an Underwater SubCycle. Because.
