Okay... but from where are you getting this information? You're not just making it up off the top of your head; you had to have read it from somewhere.
Most of it is from the Obscure Texts, and small parts are from the Sermons. I'm not exactly the best person to ask, as I read the information as it is posted on the forums. I am but a traveler through these parts, while folks such as Luagar and Prowler are permanent residents. They probably know much better than I where the information comes from exactly.
And, sure, one might say since a lot of it is from the Obscure Texts then it's not true or official, but when the information doesn't contradict anything in the series, is fun, and also interesting and makes sense within the context of other writings, then why not accept it as true, at least until we get official information that replaces it? This unofficial (and yet, sort of official) information is important to piecing together much of the deeper metaphysical mysteries of The Elder Scrolls. Without it, we'd already anolysed all that we could about Knights of the Nine or Shivering Isles or mudcrabs.
