Starsinger

Starsinger (クリスタル使い) have a connection to the great crystal that allows a starsinger to predict the future, and in certain cases, even manipulate the very fragment of time. They are considered to be "true oracles", as their prophecies are often quite accurate. To date only a certain bloodline of female clavats have been revealed to have such abilities.

"The strength of that power is said to surpass even that of the gods. But there is a price to be paid for a mere mortal to wield that magnitude of power." - Tilika

"A price must be paid if a mortal seeks power greater than his natural capability. It is with her soul that Chelinka pays. And you, Yuri, pay with the length of your life." - Kolka
