Cassiodor was originally a Harmost of Remus Sebastos, a person capable of rewriting the musical score of the Phobos. He holds the same position as Boethius, the traitor to the people of Remuria who seized control of Chaotic Symphony.
Cassiodor is also the Harmost the Traveler was seen conversing with, each time he dreams as the Imperator himself.
Because of the Chaotic Symphony, Cassiodor's soul inhabited a cat who first referred to himself as Ouranides of Ouranopolis, or Osse. Only when Osse spoke to Boethius during the Underwater Nocturne, has he gained his moniker, Cassiodor, once more.
In the Domus Aureus, Cassiodor assimilated with the Phobos, thereby filling it with his desire to end its reign. And with the help of Traveler to deal the finishing blow, the Phobos, along the remnants of Remuria, were freed, and granted entrance to the Great Sea.
