I read all about the Chaos faqs and I followed as order. The main problem is, I received all fragment (Or medallion, I guess) from the Imperial, The Waterway and from the Hunt "Orthros". I gave all the three fragment to Roh'Kenmou at Old Dalan's place in Lowtown.
And when I try to find Roh'Kenmu at the magick shop in Archades, I gave him the Moonsilver Medallion. The thing he ask me to find. And now he is gone.
The walkthrough says I have to go to the secret area at Nabreus Deadlands. I try to examine the shrine and nothing happened. Plus, Roh'Kenmou says he needs one more medallion. But I gave every medallion he need!
