@946000: [...] What's your backup?
Probably from the same Moth priest documents (can't really remember them right now. Will probably edit in), http://www.imperial-library.info/obscure_text/vehk_teaching.shtml, whatever the hell that freakin' document is that talks about that mage who was a higher-up in some magickal society, and I think that's mainly it, besides a few documents that slightly mention CHIM (it's really too many, but if i find specifics, will try to edit in).
Concerning the Dwemer, I still battle with what TRULY happened to them. I recall seeing a MK post (or someone refer to one) that stated that they "became" Anumidium and while I can believe that to some obscure degree, I find the text that states that they were displaced to Oblivion makes much more sense. I feel they just "became" a tower, but that makes crap sense.... I had a better past theory about that, but I'm so stupid I forgot it...or just remembered it too well. It's complicated.
CHIM itself "constantly distorts itself;" essentially, people don't know what the hell it is. As someone earlier stated, Zero-Sum is arguably the pinnacle of enlightenment, and I mostly believe this because it is the "common" conclusion; if someone tells you that everything is essentially the same thing and you therefore have no individuality, then the "logical" solution is to say "I AM NOT." CHIM is so rarely acheived because, like stated, it "constantly distorts itself." How the hell can you say "I AM" when "obviously" you "AM NOT?" CHIM distorts itself because it's so illogical.
Basically, only several TRULY know about CHIM specifically and fewer have ACHIEVED it after the Endeavor, which itself is so obscured to people. I used to think Zero Sum was a mistake too. Those who have actually strived for it have shown me otherwise. I also think personal character comes into play as well as knowledge.
