Korvia is a planet with an advanced humanoid civilization. Many years prior to 1960, the surface of the planet turned to molten magma, and so all the cities on the planet are hovering cities. Valzorr is part of the Korvian royal family. In the absence of the King and Queen, Zoxxo served as the Prime Minister until it was revealed that he was responsible for murdering the King and Queen.
