Like all members of the Asteri, Rigelus' true form was unknown and often required a host body to contain his power which wasted away as time passed due to the strain. He inhabited the body of a fae with cold blue eyes, sharp yet handsome features, dark brown hair, and ivory skin tone. Being in a fae body also gives him the access to fae abilities making him stronger than the other Asteris. He is also called "Rigel" pronounced as "Ri-gel."
