Sky City

The City in the Sky is the capital and home of the Oocca, located far in the heavens above Hyrule's surface. It also serves as the sanctuary of Demoko, first Sage of Time.

The Return of Sulkaris
Alerted to Sulkaris' return and goal of killing the other first Sages in 127 AG, Demoko mobilizes the Oocca for war and begins a mass invasion of Hyrule in an effort to destroy to Fallen Sage. The City in the Sky destroys much of Goron civilization on the Death Mountain rage via orbital bombardment in an effort to obliterate the Gohma, but fails to succeed in doing so. Fearing that the Oocca will destroy all of Hyrule in their efforts to kill Sulkaris, the coalition Hylian forces warring with her temporarily align with the Gohma against the heavenly invaders, allowing Sulkaris' forces to invade and infest the City in the Sky through ground portals. Though the city manages to evacuate, it plummets from the heavens, crashing into Hyrule's surface.
