If the Novun are associated with the Danuar, then we'll just have to investigate the Danuar.
Fortunately, a research assistant I know recently discovered traces of them.
Go to [%dic:STR_DIC_W_LDF5a_E7] and talk to[%dic:STR_DIC_N_LDF5a_Sopocles_E].
Ah, Akaia must have sent you. Yes, I found information about the Danuar. In fact, I located the ancient text, [%dic:STR_DIC_E_LDF5a_FOBJ_E_RuneDiary].
I went to collect it, but, unfortunately, I'm no warrior. I was ambushed by monsters and dropped the book as I ran for my life.
(This book could fall apart at any moment. You can barely make out the faded "Danuar" on the cover.)
I've been waiting for your return, [%username].
I can't tell you how worried I was that someone else would take the book.
Amazing... It's intact. The things we could learn from this!
I've skimmed some pages about an enormous catastrophe, but that's all I can tell you right now.
I need time to study this.
Go to [%dic:STR_DIC_W_LDF5a_E7] and talk with [%dic:STR_DIC_N_LDF5a_Sopocles_E].
Search for the [%dic:STR_DIC_E_LDF5a_FOBJ_E_RuneDiary] and obtain the [%dic:STR_DIC_I_doc_quest_12565a].
Return to [%dic:STR_DIC_N_LDF5a_Sopocles_E].
See Sophocles, who has found traces of the Danuar.
Akaia wanted to study the Danuar, if the Novun are associated with them, so she sent you to see Sophocles, a research assistant who has discovered a Danuar book.
You obtained Fall of the Danuar and brought it back to Sophocles. He said you could learn a great deal from the document, given time to study it.
