Kerberos

Kerberos is the Moon of Galvan, and is Antares's right hand man. Xe helps balance the cosmic energy of the domain, and is skilled in monk-like combat. Xe has a way of feeling the ebb and flow of cosmic waves with xir hands, so it was only natural that xe would become a Moon. Xe helps train potential Stars of Galvan and other domains, and has even helped raise Antares's daughter, Aster. Kerberos is very loyal, and will fight to the death for Galvan.
