The last light of dusk fell across vermilion walls and green-tiled roofs, lending the imperial city an air of mystery. The vendors along the main road had already begun packing up, while only the taverns kept their lanterns hanging high, lighting the way for passersby. A man in a blue robe walked slowly down the street. He seemed ordinary, yet every step was measured with precision, exuding confidence and composure.
