My name is Mo Hen. Three hundred years ago, the Twelve Towers destroyed my family, my wife died, and the Soul-Sacrificing Tree was burned. I signed a bone-corroding pact and became an immortal shadow slave, surviving by devouring the obsessions of the dead. In this world, there are no spells or talismans, only the power of "Shadow Refining," wrung from the darkness in people's hearts. The more I kill, the more my memories crumble, but my hatred will never fade.
Now the cycle has begun anew, and the roots of the Soul-Sacrificing Tree deep underground are trembling. Using my remnant soul as bait, I plant pact marks in other people's shadows, devour their arts, and piece together the truth.
The masters of the Twelve Towers think I went mad and vanished long ago. They don't know that hidden in my shadow are the deepest obsessions they held before dying, including the one who carved her eyes. A killing calamity is about to begin, and the towers will shake the world.
