Mark of the Crown
this subtle mark of succession was a characteristic of the true heir to the throne of Gala, but was not a specific birth-mark or identifying feature. The Mark was known to the Galacian Council of Ministers, who could test and individual for its presence. Viso was the primary member of the Council who knew the way to determine the presence of the Mark. Deep within the palace, a special room contained a mosaic floor of pale blue tile. An intricate pattern of silver marked a square within a square on the floor. Whenever a Galacian stepped into the center square, it activated a sensor system that swept the being with a cascade of lights. If the being wore the Mark, the shadows of light would outline them. A Galacian who didn't have the Mark would not cast a shadow.
