Magic era: war for supremacy

In an alternate reality, there was an era in which magic reigned as the ultimate power. Individuals blessed with the powers of magic, empires, and kingdoms sort to topel each other, gather resources to suit their desires and lust, and expand their territories. This era was themed as the 'War for Supremacy era.' Born as the first child into the House of Lucas, the royal and ruling family of the Camelot empire, Prince Lucas Zheng was conventionally annointed as the heir to the throne of Camelot whenever his father, the emperor, passed away. Prince Zheng was also passed the burden of helping Camelot and the royal house of Lucas survive for years to come from invaders and conquerors. The task was heavy; the opponents are smart and resilient, and friends and allies aren't what they seem to be. Will the house of Lucas last a long time? Will Camelot survive?
