Zayd al-Nadir is a wanderer with a cursed gift—he can lock away or reveal the deepest parts of the human mind. Haunted by lost memories and used as a weapon in the past, he drifts through a fractured world where memory is power. When he stumbles upon a dying town suffering from mass amnesia, Zayd must uncover a hidden truth buried in collective silence. But every answer comes at a cost—and the more he unlocks, the closer he comes to unraveling the lock on his own forgotten sins.
