Their civilization and society is structured under a monarchy with a king and queen ruling their people with their heir usually being a prince in line for the throne. In the non-canon Mortal Kombat: The Journey Begins, it's shown that multiple heirs to the throne must compete with one another and demonstrate their ruthlessness by fighting to the death. The victor thus becomes the ruling crown-prince who will eventually inherit the throne. Furthermore, on a single, particular day each year, it was customary to give the King a present.
Among the Shokan, there is one law that surpasses above all others: survival of the fittest and most ruthless.
Within this land lies the Kuatan Palace on a nearby plateau, complete with the huge statue of Prince Goro in the courtyard, and it is where a long line of great, ancient Shokan sovereigns that resided and ruled the kingdom from there. Prince Goro is next in line as the new heir to the throne and leader of his people.
