The Ten Sages (十聖 Jū Sei) are the leaders of the Mage's Guild. Their headquarters is on the island of Magister's City: Ishana. All the members are named after the numbers 1-10. In the Phase Shift novels, they are named after the first ten English numbers, while in XBlaze – Code: Embryo they are named after the first ten German numbers. Six of the Phase Shift era Sages are known and only four of the Sages are known in the XBlaze era. Nine is their most notable member. The ten seats of the Ten Sages have never been full.
A privileged class possessing the highest authority within the Mage's Guild. Only those that exhibited vast knowledge, experience, enormous magical power and a certain degree of contribution toward the Mage's Guild, could be appointed as one of the Ten Sages. As only few could fulfill those requirements, the ten seats were never filled at the same time.
