Introduction
Oh? You've found a jewel and you want to return it to its owner? I hear this story at least a dozen times a month ... Anyway, it's none of my business. Pay me the usual price and I'll give you the information you seek.
Cunclusion
This is a ring of the Dregson family. Judging by the color, it surely belongs to one of the youngest adults in the family. I would say Calvin or Pwyll. Anyway, you can find them both at the Grisenar Inn. They are the owners. I hope you can restore their jewelry to them.
