Siroc (Total War)

Mediator Ooccoo is the Oocca Mediator, a high-ranking position second only to Demoko himself.

First Golden Age
After the rise of Ganon, which nearly saw the holy Triforce falling into the hands of the Moblin King Ganon, the Sage of Light Rauru convinces Ooccoo that Hyrule Castle is too dangerous and that it should be returned to the Sacred Realm as it was in ancient times. Claiming that keeping the Triforce locked away from the world would lead to a decline, Rauru proposes to create a portal that could be opened to the Sacred Realm in times of need and suggests converting the Temple of Time into such a door. Ooccoo agrees and works with Rauru in secret to transform the Temple of Time into a portal to the Sacred Realm. Once completed, they create the Temple of Light inside the Sacred Realm and bring the Triforce to rest there.

Gerudo Wars
In 101 AG, after the fall of Hyrule Castle Town to the invading Gerudo, Ooccoo is called by Rauru again, who asks her to send the Oocca to help the Kingdom of Hyrule against the Gerudo. Ooccoo refuses, telling Rauru that since the invaders can't breach the Temple of Time, the war is of no concern to the Oocca, and that the Hylians will reap the consequences of bringing the war onto themselves. After having his request to see Demoko declined, Rauru begs Ooccoo again that the Oocca can so easily help save the Hylians, but she only angrily asks him if his people are really worthy of being saved, before reminding him to keep following her commands.
