Ten Thousand Lights and No Day

Three hundred years ago, the sun disappeared from the sky. The reason why everywhere has not fallen into complete darkness is because the nine "daylight cities" maintain the light in the world. The daylight is not an ordinary light, it relies on a "light book" to operate. Everyone's name, birth, death, deeds and family records will become part of the lantern book. Once a city is "removed", it will gradually lose: Road records with the outside world Records of caravans and officials Legal status of people in the city Other people's memories of this city Eventually, the city will disappear from all maps and history. Officials say this is a necessary price to keep the world bright, but no one knows the real reason.
