So, about the story of this cave: if you want to find all fragments by yourself - search secret rooms and walk to the desk in there. And if you want to read the whole thing - go to the 4th page of this thread: http://www.kongregate.com/forums/3-general-gaming/topics/465167-official-the-enchanted-cave-2-guide?page=4
At floor 62 I accidentally walked into a desk in the secret room and finally understood what journal pages everyone were talking about T_T I don't wanna start all over just to find all of them, but I really want to know the story...
