Cassiodor is a confident, diplomatic young man. His voice is full of seriousness at times. He has short, perfectly white hair, and is a Royal Tuner alongside his dear friend Boethius. He lives in Remuria, a musical city which is actually a royal palace in the shape of a gigantic organ which makes the sea vibrate when the Tuners play it. He is the last of his tribe of the Erynnies and hates more than anything the idea of fighting against "barbarians", because he himself is one.
