Actually, I'm stuck on this one still. First time I was told to find something on Ryozo, I found them in the hall of records where the dragon resides. I put them in the barrel as I was told. Then I get this quest again, telling me to find the papers and report it to the authoreties. Well, I can find no papers anywhere, Harissa don't have a chat option for Ryozo and there is no reward in the crate.
