Luna stands at the shattered window of the witness tower, caught between her reflection, a new version of herself, and the humming wall. As the scar on her palm opens a door to the lit lighthouse, she steps through into a corridor lined with mirrors that show moments from her own past—but each reflection moves differently. She follows a trail of footprints that lead to a door marked with her own name, and when she opens it, she finds a room where a younger version of herself is writing a letter to Elias Vane. The impostor's lullaby echoes from the hallway, and the floor begins to dissolve into the spiral's original geometry, forcing Luna to choose between confronting her past and losing herself in the structure that the impostor has been rebuilding.
