Ring of Power

It's an out-of-the-way side street on the outskirts of a remote town. The paving stones outside the house are cracked and the grass on the nature strip has grown wild. You had stopped in this town on your way home from a conference and your interest was piqued by the sign, telling you of the garage sale. As you expect, most of the things being sold are worthless knick-knacks and out-of-date books. However, one object catches your eye - an iron ring in the shape of a dragon. Before you know it, you hand over some coins and pocket the ring.
