Umm -- do you realize what the Worldstone really is?
The Worldstone is really the eye of Anu. It's a piece of Anu, and everything that exists, is, because of the death of Anu and Tathamet the dragon. Anu is known as the spirit dreamer. That gives a vibe of having the property of "creation" which is what the Eye of Anu (The Worldstone) was used for by Inarius.
Inarius created a pocket dimension to hide Sanctuary from the High Heavens and the Burning Hells. Anu's shining spine became the Crystal Arch upon which the High Heavens was created. Tathamet's husk became the realms of the Burning Hells.
The lore of Diablo III has become a very complex concept that's a bit hard to grasp, but doesn't really affect much what we have read in Diablo: The Sin War trilogy. The material we see now, in part, was brewed before Knaak wrote the books -- must likely. He writes based on guidelines passed on by Blizzard Creative Team.
At the time Diablo: The Sin War took place, most likely no one but Trag'Oul knew exactly what the Worldstone was. However, the story Deckard Cain is telling in Diablo III: Book of Cain comes from the pages of the Black Book of Lam Esen.
The Book of Lam Esen is part of a Diablo II quest. You find it in the Ruined Temple of Kurast in the Kurast Bazaar. Lam Esen was an ancient sage who studied the Skatsimi magic. Skatsim is the name for the Old Religion.
How could Lam Esen learn of the Old Religion when everyone's memories were wiped at the end of Diablo: The Sin War trilogy?
Only Rathma and Meldeln kept their memories. If I'm not mistaken, Trag'Oul was responsible for these two to be spared the memory wipe.
Thus, I think the clue to how the Old Religion came to be known by the likes of Lam Esen was through any of these three characters. Somehow.
