Three hundred years ago, the Heavenly Stele devoured the true names of all living beings. History books dared not record it directly, referring to that night only as the Night of Heavenly Taboo. From then on, a name was no longer merely a form of address, but proof of existence. Those without a name registry could not enter the cities, and no one would remember them after death. Ye Ming, a soul-caller from the northern frontier, has no true name, yet he can hear the remnants of the dead and borrow their power. Each time he does, he must surrender a piece of his own memory. On the night the border city falls, he meets Xue Er, a girl who carries snow. She can seal memories inside snow, but every time she uses her bloodline, someone will forget her. One restores the names of the dead, while the other preserves the memories of the living. Together, they flee the snowy mountains with a dying lamp, searching for the truth buried behind the Heavenly Stele. Everyone wants to trade the names of all people under heaven for a peaceful world, but Ye Ming insists that everyone should write their own name. Even if the world ultimately forgets him, he will reclaim the names lost that night for Xue Er and for all the nameless.
