Caelus is usually smug and funny. But deep inside, he is kind-hearted and takes his missions seriously. He would also do anything to protect his friends.
It is mentioned by many people from different factions that Caelus' will surpasses that of others. But he doesn't know what that means.
Due to the Stellaron in his body, Caelus can adapt to any Path with ease and even switch between Paths. Currently, he has the Paths of Destruction, Preservation, Harmony, and Remembrance.
