I have a theory.
What if, what if, the creator man from all the myths was one big creator man, as viewed by different people.
SCIENCE! shows us that sometimes when a guy see's a color he see's a different color than a different guy, like how dogs see everything as black and white and grey but we see infinite rainbows blending together like some kind of a, a, a spectrum of colors.
So what if when Elf-man see's the big creator man, he see's a dirty trickster (Lorkaan), then when Imperial-man see's the big creator, he see's a song-maker (like Benny Goodman or Frank Sinatra)! Then, then, when Nord-lady see's the big creator man, she see's a Tough Dead Warrior and he makes her swoon.
I call this theory "The One Big Myth."
