In Harmony in the Moonlit Courtyard, Arion and MeiLin discover a walled courtyard aglow with hundreds of lanterns under each full moon. Drawn by the legend of "The Crescent Harmony," they meet musicians who play only when hearts are free of anger and fear. Under the guidance of harpist Vessara, they learn to calm their minds, give thanks, and forgive past mistakes through simple melodies. As their harmony grows, the courtyard bursts into bloom and weary travelers find fresh hope. This lyrical adventure shows that true harmony is more than music—it is a gentle song of kindness and understanding.
