This quest was marked obsolete by Blizzard and cannot be obtained or completed.
Ask Daryn Lightwind if you may borrow her book.
This book looks as if no one has opened it for quite a long time. Its covers are quite worn, and its pages yellowed, but after examining it, you notice that it might be just what Troyas is looking for.
You pick it up, but realize you should probably ask before borrowing it.
