Urn #1 is near the mountan range that runs north and south in Demoncalw, If you follow that mountain range down near the Barracks and continue around the mountins (do not cross the bridge to the barracks) you will find a chest near the mountains guarded by some Orcs . . the Urn is in that chest.Urn #6 is located in a chest next to the hill upon which sits the Temple of Varmen where you had that battle with Morgana and her Coven of witches. The chest kind of blends in (optcally) with the hill, so you have to look carefully.
I am not sure about that entry in you log. It sounds like you need to go back to Castle Birka and talk to LG. If that doesn't work, it means you probably did something out of sequence. Ar any rate it doesn't appear to affect the main line quest as log as the seer gave you the quesr to go to Glacier's End and clear out the Drow Hive and obtain the Ether Jewel. Once you have done that and go to the normal exit portal there (with both jewels in inventory), Tamara will meet your party and open the portal to the Fortress of Anarchy (the final Battle in Part 1)
