The Sages of the Master Sword are sages of Hyrule in The Legend of Zelda: The Wind Waker. They pray to the gods to keep the power to repel evil inside the Master Sword, the blade of evil's bane used to destroy the king of evil, Ganondorf, if he ever were to escape from the Sacred Realm. They pray to the gods by playing the harp and the violin inside the Earth Temple and Wind Temple respectively. The Earth Sage keeps the sword's edges in shape and the Wind Sage keeps the sword's gem glowing and the blade sparkling with evil-destroying power. Eventually, Ganondorf broke the seal and attacked Hyrule, but a hero did not appear to stop the malevolent warlock. The gods flooded Hyrule in response to seal away the evil.
Hyrule became the Great Sea and the survivors settled on the mountaintops of Hyrule, now islands, while Ganondorf, his army, and the rest of Hyrule were sealed in time on the ocean floor. Ganondorf managed to escape, and sent Molgera to kill Fado, the Sage of Wind, and Jalhalla to kill Laruto, the Sage of Earth. The two Sages were assassinated and the Master Sword fell powerless. The power vanished, the gem went black and the edges went dull. However, their magical instruments survived and were passed down their family lines. After Link from The Wind Waker took action, their spirits appeared before him and instructed him to awaken their descendants as the new sages. Makar the Korok (Fado's successor) and Medli the Rito (Laruto's successor) were awakened and restored the power to repel evil to the Master Sword. Medli restored the edges and Makar restored the power and gem.
