Be sure to read ALL the books you find. If you dont then you probably will miss the ranaar language books. I missed book 2 and 3 and now I need them to finish a quest in act 4. Im sorta stuck because I missed one book in act 2 and one in act 3 and there is no way to get back and read them.
I missed them although I have read all the books I have found but I guess thoose language books are pretty hard to find.
It's not that difficult to guess the language of the Raanar: the letters are similar to latin alphabet.
Since I figured out that the message on the box was " Arch Enemies Lost In A Dark Ralm Soul Forged For Ethernity" guessing the raanar scripts wasn't difficult <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />.
