was cruising the internerd; found a nice piece of well thought out fluff about the emprah, and his relation to the gods of chaos, the old ones and the ctan.

personally whether or not its cannon, I tend to enjoy well reasoned "undercurrents" in a story, this is the main reason 40k appeals to me, or any of us I imagine, is that even if the fluff is superficial in some places, its very much mythic and primal in relation to the God emperor, the chaos gods, and the other various god like entity of eldar, tyranids, orks etc.

so give this a read if your interested in that sort of thing.
