I believe it is about a man who is stricken with so much power, due to inheritance, and at first he was a good leader much like the Roman emperors/kings but was tainted by the power he had, Because at first they respect him by chearing Long live the king, that now he has gone powercrazy and slays anyone in his way. Much like the story of arthas from world of warcraft, yea I'm a nerd: D
