In the eternal city of "Etta Castle", memory is the currency in circulation, the cornerstone of power, and the most deadly drug. People can sell their painful past in exchange for a moment of happiness; the powerful build their immortal rule by devouring the wisdom and experience of others.
Karen, a top "memory weaver", his talent is also his curse - when retrieving memories, he will experience everything in the memory immersively. He wanders among the reverberations of other people's lives, and has long been unable to distinguish between himself and echo.
A seemingly ordinary request for retrieval of dying memories plunges him into a vortex of conspiracy that subverts the entire city. He accidentally obtained a "key" that could unlock the truth of the world - an encrypted horrific memory from one of the city's founders. This key is not only the core of power that the ruling group "Glow Parliament" aims to gain, but also the only hope for the bottom resistance organization "Chorus of the Forgotten" to destroy the old world.
When the "source of consciousness" of the entire city - the huge ancient crystal tree "Tree of Silence" - begins to emit the wail of death, and when pursuits and lies come from all directions, Karen must make a choice: should she continue to be a numb bystander, or should she face the pain and love that does not belong to her and weave a path to salvation? In this cage built of memory, what he wants to find is not only the truth of the world, but also his deprived identity.
