Go to the Temple of anjdfnas to find asdasjnsdfn who is the only person who knows the whereabouts of sajnksdfkjas. If you give them this book they will tell you the location of the dungeon of askjnasdkja wherein sdfkjnsdfkjsfd will give you the answer to a riddle which sadfkjsndfsdf can use to convince asdasdasd to marry them. Good grief.
