The 13 Signs of the Sideriac are the stellar constellations of Hyerune that appear across the night sky throughout the year. Many of the constellations represent mythological animals from the ancient stories told by the earliest inhabitants of the world and have remained popular to this day.

Many people believe that the prominent Sideriac Sign during the time of an individual's birth will influence that person's personality and success in life. Furthermore, these signs are sometimes used to predict future events in an individual's life though this is mainly done in the Kingdom of Valoria.
