I found this recently. Blew my mind completely. I've been playing TES games since Morrowind, and have sunk hundreds of hours into each game. I knew that they had some serious history and lore, but I had no idea that it ran this deep. This is some uber-geeky stuff, delving into the lore and philosophies of the game and cracking it open to get to a theorized gooey center. It's very long, but very fascinating, and you might have to use some sort of illicit mind-altering drug to really get it.
