Discovering Ruunvald, Vol. IV

Found

 * Ruunvald Excavation, near exit to temple on barrel

Bugs

 * Just before exiting into Ruunvald Temple, turn around and walk back into the main cave, on the left at the brazier, the notes should be on a barrel there. Apparently, it tends to fall into the barrel, a clipping issue. To collect the book you might use  on the console and fly into the barrel. Sometimes the book may lie next to the barrel.
