Tabula Rasa or the blank slate. It is a philosophical theory that indicates that at birth the mind is a "blank slate" without rules for processing data and that data is added and rules for processing are formed solely by one's experiences.
The Boy-King Nico Parros is a blank slate. He is at a crossroads and his fate is in the hands of two people thrust into a role as his "caretakers" Santana and Ezra. What impact will these two vaconics have on the king? What impact will they have on the World of Vala?
