Corwyn begins to tremble. He looks both confused and scared.

"I swear to you I have no idea where that ring came from! I would never have repaid your generosity by stealing from you! You have to believe me! The last thing I remember was hunting in the woods, then waking up in the clearing last night ..."

He begins to look a little green around the gills again and vomits a second time.

This time, there is no gold, but you note that he's regurgitated a variety of small bones - rat bones by the looks of it.
