I did all of the wishes for Ryneus and defeated his possessed soul. I went back to his cabin where I was supposed to get him a horse to take him back to Ark. I got the wild horse nearby and came back to the cabin where he was laying in bed. He said something about making a fire. From there I interacted with him and get "Silence". My quest for "A song in the Silence" updated to Return to Arc with the blackstone. However I do not have a blackstone in my inventory and the other quest line for "Salvation of us all" still says Find the Dal'Geyss blackstone and bring it back to Archmagister Merrayil. I made my way back to Ark and returned the other two blackstones but there is no option for me to turn in or give him the supposed third one I got off of Ryneus. Am I missing something here or is this a bug? In the cave Ryneus said that the blackstone was in an amulet but I have searched the entire household and village and cannot find it! Has anyone else had this issue or possibly know what direction to point me in?
