Gyges

History
Gyges was the King in Ancient Greece. After coming into trouble with the Roman Mafia, he had a mage build a ring that could turn him invisible so he could flee the country. He managed to flee the country and go to live a quiet life as a shepherd up north, until he realized that the ring had two other properties. The ring made him immortal, and every few years, it would create an invisible clone of him that would walk from him in an opposite direction.

Current Impact
The clones of Gyges still exist today, though it is unknown where the original is. The clones often travel around and find people to mark as their companion, only appearing to them. These people are then often marked as mentally ill. Basically, Gyges is the invisible guy who homeless people speak to.
