Mysterious Blue Pan's Flute

What do you want to ask me about? What is this?! The Pan's Flute! And it's blue, too! This is the first time I've seen one like this. I know that a spirited knight's steed comes to the sound of the flute... But why is it blue?! Take it to Archaeologist Jajan in Dratan. He studies the secrets of the gods. Perhaps he knows more about blue flutes than I do.
