Silenius au Lune is the ancestor of the modern House Lune, elected as the first Sovereign of The Society by the other Golds after their conquest of Earth. Silenius was elected as the first Sovereign by fist generation House Raa, led by Akari au Raa. Akari was made the Imperator of the Society. Together, they formed the Pax Solaris. 
Somewhat akin to the phrase "between a rock and a hard place," Silenius had faced a dilemma of the like during the land grab after the Conquest of Earth, and found a third option, or a "narrow path between. Barely wide enough for the edge of a stiletto."
