Wearing a dreary gray and tattered looking robe, an old man with disheveled hair, and bloodshot half opened eyes steadily took steps towards them.

After the art piece was snatched, it was eventually resold before making its way into their hands, and after finding out, he had run over with determination in his heart to get his masterwork back!
