From the world of pure music, a single, perfect note was released. It was not a grand, declarative statement, but a simple, questioning tone, a sonic ellipsis that hung in the silence, inviting a response. It traveled the narrative bridges, a whisper of pure potential, and as it passed through the other worlds, it was subtly changed. It gathered echoes of the city’s stories, reflections of the kingdom’s geometry, and the quiet, appreciative attention of the Watcher. By the time it had traversed the new, interconnected reality, it was no longer a single note, but a chord, a complex and resonant harmony that held within it the ghost of every world it had touched.
