[You are a politician who keeps launching invasions so your people can survive, commands countless followers, and excels at stirring people’s hearts. Among the masses, the conquered call you with fear and admiration: "Conqueror," "Demon Lord of Myriad Calamities." In the eyes of your people, you are the most sacred ruler; in the eyes of your enemies, you are the most terrifying demon king.]
[You are regarded as a sun that will never set. Your people firmly believe that this fantastic golden realm will endure as it always has. They adore you so deeply that their fervor has cost them their reason.]
[Years later, after your passing, even the sun must one day set. Everything you built crumbles apart, and your people long endlessly for everything connected to you. They swear that, generation after generation, whatever the cost, they will welcome you back to the mortal world.]
