Joel agrees to help. But soon after he arrives in Spectraland, the situation takes a turn for the worse: the tropical island's majestic twin moons suddenly burst into flames, and Wavemakers-the people with the power to create magic through music, of which Joel is one-begin to go missing. Now Joel must solve the mystery of who is behind these malevolent misdeeds before he falls victim to them as well. Could it be the Silencers, a group of angry individuals who are opposed to the Wavemakers' very existence? Or perhaps another, even more sinister force that no one-including Joel-is expecting...
