In Ancient China's Han Dynasty, there was a little county -- Lou Lan -- near Han. As a show of goodwill, Lou Lan gifted Han with their prince and princess. Sadly, some years later, they killed one of Han's peacemakers, causing the Han emperor to become incensed and consider executing the prince and princess. Luckily, their loyal childhood friend -- the empire's royal protector -- gave them his gate pass, allowing them to escape. Thus, the prince and princess embarked on a long journey back to Lou Lan.
