Nosferatu

Noblesse is the title given to the strongest member of the Noble race. The Noblesse is one of the two pillars of Noble society, equivalent in standing to the Lord. While the Lord symbolises authority, the Noblesse symbolises power. The Lord leads and rules over the race publicly, but the Noblesse is the Noble's hidden protector, judge, and executioner.
But what if there was a being higher than the Noblesse a title shrouded from the ages, a being that was older than civilizations? What happen if the Noblesse and this being met?
