The nine mountains that guarded the land collapsed in a single night, and gray mist sealed off the earth. A nameless lamplighter, A Deng, awoke in a ruined temple with no memory of his own name. At night, he became the master of a palace that roamed the land, following the lamp's cable from city to city to protect the people and banish evil. At dawn, he returned to his ruined body and pretended to be an ordinary mortal. But the lamp should not have been lit: the Soul-Guiding Lantern had gone out long ago, yet now it burned for him. In the mist, he picked up a name: Xie Lan. And in the depths of the sea of mist, a mountain was about to fall once more.
