Fairy Patrol. The Show Goes On. Official Novelization

Once upon a time, gnomes and elves lived in peace and friendship. Together they guarded the ancient treasure — the willow lute. And nothing in the world was stronger than its magic. The evil sorcerer Satyr and his servants — the fauns attacked the gnomes and elves to take the marvelous instrument. However, he lost this battle.
But before his exile, the sorcerer shot an arrow at the lute and broke the musical instrument into two parts. Since then, the paths of gnomes and elves have parted. Each
nation took its half of the lute and carefully kept it, passing it down from generation to generation. But one day a terrible thing happened — someone decided to steal both parts of the instrument. The girls from the "Fairy Patrol" must find out the identity of the villain and return the treasure!
