Might have been true at some point but the lore is very well documented in novels now.
Lim-Dul has a lot of background, and it's interesting. If you wish to remain ignorant don't bother clicking.
I'm not saying it's not out there, I just don't think that a majority of players have historically gone out of their way to read the novels, so I'd wager that's still the way most players absorb the lore.
