(...) as far as i know, reading the book is not yet..er.. possible... so im interested in how you interpret the Book of Names specifically, and if you could fill me in on something i may have missed in the game.
Hmmmmmm, actually I didn't know that, honestly.

I just assumed that it was known to Laanx's priests to provide guidance. I was inspired by some parts of Yliakum's history (
http://www.planeshift.it/setting_history.html):
These quotations follow a chronological order in the history section:
About the Book of Names (in the 2nd Epoch):
"In her [Laanx's] exile, she wrote the Book of Names for, even if she was confused and her mind distraught, she did not forget her desire to be worshipped by the people."
About Laanx rule over Kadaiko's Lemurs (in the 3rd Epoch):
"For a period, Laanx ruled Kadaikos harshly, giving to the Lemurs inflexible laws and a strict hierarchy."
About the Laanx's Xacha followers (in the 5th Epoch):
"Some of them [the Xacha], circumvented extinction and went back to their ancient traditions, while the
others spontaneously created a clergy and faith based on the Book of Names."
So, this last quotation led me to the conclusion that the Book of Names, have been written by Laanx herself/himself, would be the corestone for her/his laws and hierarchies given to her/his followers. But I return your own doubt to you: maybe I'm missing something I don't know, and you could also fill me in on that

Maybe an information wich I don't know/remember given by a NPC.
Besides that, if the Book of Names indeed can't be read (I don't mean
implemented in game, wich is a different question) by Laanx's followers, they surely have religious codes, sacred texts and theological books by wich they organize their religion and discuss their faith. I think this is the opening to different religious aproaches to the same god, thus improving roleplaying the way I said before.
Shouldn't this discussion be moved to another forum? How can it be done?
Well, waiting for more opinions, as always.
PS: I just remembered something: the Book of Names is on Laanx Great Temple in Hydlaa, in the second floor. I believe that's a room for priests only, but still, the Book is accessible to mortals, them. Or... the Book is there, but unreadable or untouchable by mortals, it would be just a manifestation of Laanx's power. I still take the first option, as long as someone doesn't prove it inapropriate.
