In the vibrant valley of Cantaria, music is a tangible force that breathes life into the world, making rivers flow and crops grow. But a creeping phenomenon known as the Great Silence is freezing the land into a muted, static wasteland where no sound can exist. Carys, a humble Song-Catcher who harvests melodies in glass jars, finds herself the last person capable of hearing the world’s fading heartbeat. Accompanied by a floating bell-fox, she must brave the frozen wilderness to reach the Echoing Mount, find the mythical First Chord, and shatter the creeping silence before the music of the world is extinguished forever.
