There is a ring that has floated through time, a cursed ring that came to be known as the Borgia Ring, due to having belonged at one time to Lucrezia Borgia, but she was not the ring's creator. This is a small fact that history has forgotten, but is also inconsequential, as it is the ring's power that is the point. The ring has a unique power, or as some would attest, a curse. The ring has the power to turn whoever reads the inscription, "In Canis Corporea Transmuto", into a dog.
The question is, who's hands would the ring fall into next?
