Sage

Those who guard the Sacred Realm with the royal family are called sages. The mysterious power of the early Hylians has largely been lost as eras have passed, but the sages and their descendants still possess this sacred power.

Each time the world falls into certain crisis, a new group of chosen sages awaken to combat evil.

In all of their appearances, Hyrule's sages and their descendants are fated to be targeted by Ganon and the forces of evil.
