Okay, let's see if I can explain whats happening! I am on Sentinal Island, I have done all of the preliminary's like choosing my 4 partners, I have lit the 3 candles and I can't get too the boat on the tree. As you suggested I went through my contents and just discovered that the "Arcane notebook" is not in my contents. It's in the logbook that I lit the candles and that Sassan's ghost asked me to resurrect her. I've wandered all through Broken Valley and did all the tunnels that I could find. I spoke with the imp near Maxo's tower that say's that that he can't dechiper my information because I am missing three parts of four. So at this point I am really confused because I have done alot of searching and I still can't get into the Battle Tower. Please help!!!
