Biography
Prior to the events of the game, the Ocean King was attacked by a vicious creature named Bellum. Bellum was vile and could suck the life out of anyone who entered the Temple of the Ocean King. Bellum wanted the Ocean King's life force and sealed him in the Temple of the Ocean King and cursed the temple, so that should anyone enter the Temple of the Ocean King, their life would be sucked out of them. However, purple safe zones were left untouched by the curse, protecting those courageous enough to ascend the tower.

The Ocean King, quickly losing his power and feeling his life force fading away, magically cloned himself into Oshus, a wise human, and made his residence in a house on Mercay Island. Oshus also created the Phantom Hourglass filled with Sand of Hours so that he could enter the tower to maintain watch over Bellum from time to time until someone with the strength to defeat him arrived on Mercay Island. While maintaining the guise of Oshus, the Ocean King met Ciela, the spirit of time and courage. She had transformed herself into a fairy form to escape Bellum's wrath; however, her memory was lost and Oshus took care of Ciela, who came to call him "grandfather".

When Link is shipwrecked after Tetra is taken away by the Ghost Ship, he awakens on the beaches of Mercay Island, where he is awakened by Ciela. The two talk with Oshus about how to rescue Tetra from the Ghost Ship. Oshus tells Link that if he were to look for the Ghost Ship, he will never return. Later on, Oshus reveals the Phantom Hourglass to Link and also reveals Ciela's true identity as the Spirit of Courage. Aboard the Ghost Ship, Oshus reveals his true identity as the Ocean King and tells Link about Bellum.

After the final battle with Bellumbeck, the Sand of Hours helps free the Ocean King from the curse placed on him, allowing him to assume his true form once again. The Ocean King then tells Link and Tetra that their world will be free from the Ghost Ship and its evils before fading away.
