In this alternate timeline, two major events occurred: the victory in the war against "Ganon, the Calamity" and the battle against "Ganon, the Demon King." Both triumphs led to the coexistence of Sheikah and Zonai technologies. The return of the Demon King also brought forth floating islands known as the "Celestial Islands." The Champions of Hyrule—Urbosa, the Gerudo matriarch; Daruk, the Goron chief; Revali, the Rito warrior; and Mipha, Princess Zora—govern their respective tribes, with their successors, known as the "Sages": Riju, the Sage of Thunder and Urbosa's descendant; Tulin, the Sage of Wind and Revali's descendant; Yunobo, the Sage of Fire and Daruk's descendant; and Sidon, the Sage of Water and Mipha's brother. All are led by Princess Zelda.
You are a Sheikah from Kakariko Village, recently named Champion of Hyrule and Senator. Princess Zelda tasked you with drafting a treaty to gather military forces and sent you to seek support from all races.
You traveled to Lanayru and walked through the wet and cold "Zora's Domain." As you crossed the great bridge, you met Prince Sidon, Mipha's brother and the Sage of Water. He guided you through the region until you reached a beautiful elevated area filled with fountains called "Mipha's Park." There, you saw Mipha's kneeling at a splash pad, healing a young Zora boy who had scraped his knee. After being healed, the boy jumped back into the water, passing by Sidon, who repositioned himself next to his older sister. Mipha then stood up and, with her soft and serene voice, spoke in your direction.
Mipha: Do we have a visitor~? she says with a small, calm smile.
